Title: Buy twice the number of EON518s versus PRX718XLF? Make your case to dissuade me.
Post by: Benjamin Goulart on September 10, 2013, 02:16:22 pm
Comparing the 18 inch powered ones, is the top PRX 718xlf sub really worth more than twice the EON518s sub?  For the price these are going for, you can get twice the number of EONs that are easier to carry and end up having larger box volume in pairs per the PRX.  The EONs also have neodymium magnets while the newest JBL PRX has regressed to ferrites.  How much better construction could the PRX really be to make it worth it?  And between the added box volume of two EONs AND the allowance to run each at a lower, less distorted wattage level, then isn't the PRX pricing unreasonable?  If you really think going the PRX route is worth the price & weight increase and halving of box volume per dollar, make a convincing case for it.

Eon has a 42 to 100 hz plus/minus 3 dB

PRX has 35 to 87.

Eon Max spl is 129 dB

Prx max spl is 134 dB

So the PRX goes deeper and is about as loud as 2 EOn cabinets. If I was buying it would be worth it just to carry half as many cabinets.

Two eons is 130 lbs. one prx is 80 lbs.

Anyway, I suppose this means I can read a spec sheet... We're you looking for something else?

I wouldn't be carrying both EONs at the same time.  Its lower weight would be a benefit.

The box volumes are also comparable, so from a pure physics standpoint two EONs would have nearly double the box volume.  Isn't that good?

I don't trust response specs on speakers.  I find they're usually exaggerated, especially on new models that are now using inferior components to last year's model and there's an obvious incentive to try to justify the new model.  Might go deeper.  Might not.  Either way, I will convolve/EQ the system.

Either way I will also spend about the same amount of money.  Car space isn't much of an issue, but carrying weight might be.  Are 2 PRXs going to get louder and sound better quality-wise than four or five EONs for the same price?

Lower quantity of higher quality wins (basically) every time in audio.

You only gain volume when the boxes are pointed at the same space and the frequencies are of course in line with each other. In other words you will not see a 3db boost at all frequencies when you put two EON's per side up. You could however increase your coverage area. Suffice to say the PRX line will sound better out of the gate, produce more volume on it's own. The only trade off that you will experience by going with the PRX is that you will have less coverage than the 4 EON's would produce.

I would go for quality over quantity myself. But your business model will be the ultimate factor. If you pull more low end business and need more speakers to cover the area, then the EON's would be a good investment. Conversely, if you need to cater to a higher end client that will pay more and you don't need 4 boxes to cover your general area, then the PRX may net you some more pull for compensation? You have to follow the money. I have a Behringer powered mixer that was $300 bucks. It is my busiest mixer and has paid for itself 20 times over and continues to just make me more money. My Yamaha LS9-32 doesn't go out as much and is going to take a bit longer to pay for itself and generate profit. I have a set of first gen PRX's and theyt too have made me lots of money. I got them 6 years ago and can say that they have paid for themselves many many times.

You're mixing up tops and subs.  The OP is talking subs, you are lost somewhere in between.

To the OP:

You are not grasping the difference in output.  If the specs are accurate (or comparable, which is likely in that both products are JBL), the 7dB difference in the SPL rating means that the PRX's are putting out TWICE THE SOUND of the EON's.

If you need a small sub or a pair of small subs, grab a pair of EON's and use them for the light hauls.  But if you want serious SPL out of your subs and don't want to wrangle twice as many boxes, go with the PRX's.  They'll take up less room to haul and less space to deploy.

Besides...EON's suck.

The probability of two EON518S coupling indoors and producing a 6dB increase in average SPL and having less distortion than individual units running at the same SPL is very good, even if they are not within one wavelength of the frequency-weighting being measured.  There may be some diminishing return if they are not coupled and near each other in numbers higher than two, but that can be resolved easily by actually putting them next to each other.  And there's no option to spread the PRX's out if half the number are purchased of them at twice the price.  I understand that you guys have serious hang-ups about the EONs, I would just like to hear specifics about how the new PRXs are actually better than twice the number of EONs.  How are the woofers better?  How are the plywood cabinets better?  Are the amps better beyond just the watt multiples?  JBL dropped Crown.  I already know the EONs have higher magnetism-per-mass magnets, lighter cabs (65lbs versus 81lbs), and would be double the cab volume with twice the number of EONs over PRX's.  How are the PRX's so superior that double the number of EONs is not worth it when space (both in vehicle and venues) is not a consideration?  Someone mentioned on another forum that the EON voice coil is only 2".  Anyone know what the PRX coil size is?

PRX plays lower, gets twice as loud and sounds better. 

That's all.

None of the shit in bold matters.  Really.

Here's the deal.  The PRX get louder, go lower, and sound better doing it.  Each PRX is roughly double the output of the EON and goes almost a half octave lower, something the EON can't do no matter what. 

As for transportation, venue, etc.  Everything has a cost.  Everything.  Even just sitting there taking up space.

You seem to have posted with your mind already made up.  Why the trolling?

And if it hasn't been clearly explained yet, 1 PRX-XLF sub is just as loud as 2 Eon subs. Plus it has the benefit of playing a half octave lower.

Why would you buy inferior subs again?

Iím trying to give one of the options a fair shake in a discussion that might have a tendency to move away from rational facts.  It certainly moved towards calling me a liar and a troll in a hurry, though.  Thatís welcoming.  I did not have my mind made up.  I still donít.  A lighter sub is appealing.  I can lift 65 pounds without a problem.  Iím unable to deal with hundred pounds in large bulky configurations easily.  I might be willing to deal with 81 pounds if the sound and construction is superior.  If the results are roughly equivalent in output and sound quality, though, which is certainly possible based on the prior facts I had that are devoid of biases against intra-brandings, then I would spend the money on the lighter form factor.  If the PRX is definitely superior quality sound & construction, including at high volumes compared to 2X the EONs in the same situation, with facts to back it up, then I will deal with the additional weight of lifting the individual subs.  But itís pretty clear thereís a lot of bias and attitude that one needs to weed through to get to the facts on any of these audio forumsÖ whether those biases may be justified or not.  Iím not going to spend my money just based on emotionally-charged comments.

Lower weight per sub, larger cab volume size with multiple subs, and lower SPL per cab necessary for the same output (which may allow for lower distortion) are the only potential reasons to consider the EONs.

The XLF canít quite play a half octave lower, but I understand what youíre saying.

Why do you keep mentioning cabinet volume?  I don't understand how that matters to the discussion.  I also don't see how, if a cabinet is being run within its limits, lower spl per cabinet is an advantage. It just means you need more and doesn't mean a thing in regard to distortion. 

Additionally you seem to want people to prove a negative, that the prx isn't better.  You can try to prove the eon is better and you can try to prove the prx is better but you can not prove a negative.

One argument that hasn't been made about the prx is that they are a new production run.  Given that jblmis going away from neodymium due to rising cost and limited availability, how long do you think replacement drivers will be available for the eons vs the prx.

The argument seems to break down like this:

2 eon more or less equal one prx except the prx goes lower.  You would rather carry 60# twice than 80# once, and apparently don't have a hand truck to move your subs or a ramp to load your vehicle.  You have unlimited truck space because you don't have a problem carrying twice the volume in subs.  You aren't concerned about the lower half octave you would be missing.  The choice seems clear.  Many of these points are what would swing most people to the prx but not you in YOUR situation. That's fine. Enjoy the subs.

Not only that, but I have used both of these subs in question and THERE IS NO COMPARISON. The PRX is as close to a real big-boy sub you can buy from the MI market. The Eon sub is a toy bought by know-nothing DJ's that shop at guitar center.  So, if cabinet volume means that much to you then, by all means, buy 4 eons. It doesn't matter to me a whit....

1)I might be willing to deal with 81 pounds if the sound and construction is superior. 

2)If the results are roughly equivalent in output and sound quality, though, which is certainly possible based on the prior facts I had that are devoid of biases against intra-brandings, then I would spend the money on the lighter form factor.

I am just a below x2 average joe doing some small scale rental for parties, do not even own prx series till today due to the price.
Previously was comparing eons 518 with 618xlf, bout 3 weeks ago was asked to go down jbl's distro to listen to the 718xlf as the agents wants to earn the commission.

1)Sound wise on prx series sub, (618xlf or 718xlf) really sounds better, & it gives out lower frequency better then Eons 518s.(I was also considering eons too, due to cheaper price-tag as i hv $$ issue).
Construction wise - To me, they about there, unless i ripped it apart to see internal bracing.

2)Sound quality wise, PRX is better>> As for output, if you play them soft, prx still gets to hear "more" deeper bass. If you play them loud, prx gets louder &  sound nicer with the rumble.

3)I do not have facts to show you as i never record it down when i test them myself.
(I believe you, getting the sub, will turn them up. If not; it defeat the purpose of the xlf sub that used 1500w "Not sure if that number is peak/program or continuous", if not using them loud, might as well get some computer sub and call it a day, No?).
*I do not know if 1pc 718xlf sounds as loud as 2pc eon518, but 1 pc 718xlf is louder then eon518 at same setting at both plate amp's back, only xlr is changed & songs repeated.

4)Maybe you can try testing your intended purchase with other products that are recommended with 30Hz~35Hz content, then you will know why PRX is better. Yours ears will then tell you if those are facts.

5)Maybe the FS of the said driver of "2278G" from 718xlf is lower then the driver "268G" used in eon518s, thus able to play lower frequency better.
OR; the internal crossover is playing tricks.
Distortion-If all are at their max power, i do not know the xmax nor the limits of each driver, BUT; you can let 3 of the sub (eon518/618xlf/718xlf) to bottom out also, no problem.

6) Half a octave or not, me a noob does not know, but its does sound better with deeper bass & nice rumble. i trust my ears.

Just a thought; if $ is not a concern of yours; go get Danley or built Lab horns, play louder & deeper/lower.

Never said I didn't care about deep bass.  And while you cannot metaphysically prove a negative, one has to assume there is not going to be a significant difference between two roughly similar things until there is sufficient reason to think otherwise.  Otherwise one must assume they are enough the same once one accounts for such obviously differing issues as total wattage (i.e. twice the lower wattage units).   Saying "EON sucks" or "EON is for amateurs" or "you're a troll" doesn't make much of a convincing case.  In fact, it tends to undercut your arguments.  If you know anything about engineering challenges, then you should know thereís often a possibility of achieving amazing results on a cheaper, more compact, or lower-weight requirement.  And yeah, the specs do not indicate quite even half an octave more extension, and with how multiple subs interact to sometimes smooth frequency response (there are actual tests that prove this can happen), I had to assume that improved response with more EONs was a possibility that statements about the 1 EON being inferior to 1 PRX was not accounting for.  Across multiple forums, with some pretty good specs (still not complete info), and some very generous tests some have said they've run, it looks to me like half the PRXs than EONs is very possibly the better-sounding route.  The more reasoned arguments are compelling that itís likely worth the extra weight.

Why do you keep mentioning cabinet volume?  I don't understand how that matters to the discussion.  I also don't see how, if a cabinet is being run within its limits, lower spl per cabinet is an advantage. It just means you need more and doesn't mean a thing in regard to distortion.

3)I do not have facts to show you as i never record it down when i test them myself.
(I believe you, getting the sub, will turn them up. If not; it defeat the purpose of the xlf sub that used 1500w "Not sure if that number is peak/program or continuous", if not using them loud, might as well get some computer sub and call it a day, No?).
*I do not know if 1pc 718xlf sounds as loud as 2pc eon518, but 1 pc 718xlf is louder then eon518 at same setting at both plate amp's back, only xlr is changed & songs repeated.

4)Maybe you can try testing your intended purchase with other products that are recommended with 30Hz~35Hz content, then you will know why PRX is better. Yours ears will then tell you if those are facts.

5)Maybe the FS of the said driver of "2278G" from 718xlf is lower then the driver "268G" used in eon518s, thus able to play lower frequency better.
OR; the internal crossover is playing tricks.
Distortion-If all are at their max power, i do not know the xmax nor the limits of each driver, BUT; you can let 3 of the sub (eon518/618xlf/718xlf) to bottom out also, no problem.

6) Half a octave or not, me a noob does not know, but its does sound better with deeper bass & nice rumble. i trust my ears.

Just a thought; if $ is not a concern of yours; go get Danley or built Lab horns, play louder & deeper/lower.

Doesn't weight per sub become a horrendous problem with the Lab subs? 180 to 300 pounds each?  I have a difficult time just lifting a bulky 100lbs into a vehicle.  It seems like I'd need a crew of three or a ramp to deal with a Lab.

Look man, these guys are right. Any of the XLF PRX boxes are just going to sound much better and about twice as loud as the EON, and take up half as much total weight and a reasonable per box weight. I've used both the latest EON and the 618XLF. The EON sub sounds 'fine', about all I could expect out of a sub at that price, but the PRX is a pro product. Sounds like a different class. The opinion here is unanimous, not sure what you can ask for besides that.

Well, there's nothing metaphysical about _this_.

The probability of two EON518S coupling indoors and producing a 6dB increase in average SPL and having less distortion than individual units running at the same SPL is very good, even if they are not within one wavelength of the frequency-weighting being measured.  There may be some diminishing return if they are not coupled and near each other in numbers higher than two, but that can be resolved easily by actually putting them next to each other.
Not within one wavelength but theoretically within 1/3 wavelength to avoid cancellation at any listener locations and within less than 1/4 wavelength to get more than the nominal +3dB summation of two random sources at all listener locations.

Why do people ask questions and then argue when they don't like the answer?

There is a large part of the population that only wants validation of their opinion. He is not really asking a question. What he is really saying is, tell me how smart I am that I reached this conclusion all on my own.

Then when the community tells him otherwise he gets defensive.

Sucks for him. But in a way it also sucks for me, because guys like this end up providing the shitty PA's that I have to use night after night. I can't tell you how many times I've walked in to a club to see somebodies "better idea" of a PA system.

I agree, it is silly. I sympathize with the urge to seek validation of pre-existing beliefs that are not well justified, though. I fell victim to this when I was first here, it is very easy to justify something in your mind when other people are telling you it is OK - so people seek that scenario. In real life and on the forum I now try to consider how what I want others to answer affects how I form questions of them. Another thing on my personal list of weird real life Internet forum lessons...

If he's my competition, then yes - he should buy EONs.  My PRXs will spank him right out of a job.

Knowing nothing of either cab.
If 4x eons have same cost and Db as 2 PRX. PRX having lower bass with the only advantage being each eon is 20lb lighter. Wouldn't you take the extra 1/2 octave,deal with the 20lbs and walk to the truck 2 less times?? And why is total box volume a concern,I allways thought is was quality of driver with the correct box around it?
And besides think of concerts would they use 2x inferior gear to get to the same result,just to save weight?
