I've had really good luck running a Crest Pro9200 off of regular services.  2200WPC @4 ohms.  I don't think you need the 30A unless you bridge it.  Pretty simple, no frills, just a basic clip limiter.  But if you're running external DSP it's reliable, not too expensive, and works well for LF.  In a PSW sub shootout some years ago, the Crest and a PL6 were the only amps that produced an audible difference on subs.

That's also a good choice.

The biggest thing is to use a decent quality amp and stay away from the cheap ones.

That being said-the IPR 7500 is a surprisingly good amplifier-especially for the price/weight.

I picked up two IPR7500's from a member and so far in my testing they appear to be very solid.

I am not really asking much of the reserve as I have them powered with a 240V 30 AMP circuit.

Running two 18's a side (generic B&C loaded cabinets 18PS100's)

240V, yes.  208V if you're on 3-phase.

I'm looking into the TH-118s (a pair as well) and would like to run them with a PL380. That said, this talk about the PL4.5 has me intrigued...

I can only comment about the Danley products.

When you say 'spend a lot powering", that is often a misconception.

You don't have to use a large power amp-just because the cabinet is rated for it.  Because of the higher sensitivity, you will get more sound out of the cabinet as compared to a front loaded cabinet.

So for the same size amplifier the horn cabinets will be louder.

But also because they handle more power (voltage actually), they can get even louder.



So between the 2 TH118s and a single DBH218.  The drivers are the same-so the total power to do either setup is the same.

The TH118s are a lot easier to move around for 1 person and get up stairs.  The DBH218 is a bit harder to get up stairs and out of vans/pickups.

The output of 2 Th118s vs a single DBH218 is roughly equal.


The TH118s will have a little smoother low end, while the DBH218 will have a bit more punch on the top.

A single DBH218 costs a little less than a pair or TH118s.

The physical sizes are also a bit different and the DBH218 could take up more floor space.

For overall portability, the TH118 easily wins.

Hopefully that helps.

Not to be picky but a single DBH218 is a little more than a pair of TH118's (:

T.J. is right, not allowed.

Bad Josh! Your punishment is to listen to Skrillex on a system consisting of JBL 4530s run full range, with piezos for HF.  106 dBA for 2 hours.

ye gads! Doug that sounds mighty... harsh???     

But yes, I thought it makes good sense with the built in presets and all that, but I can see where I ran afoul of the rules. Sorry about that.

So I guess I'll take my punishment and move on... and let it go.

That said, the Crest Audio Pro 9200's are really solid basic amplifiers, you could run two TH118's per side with no problem.

Also, the Crest Audio Pro-LITE 7.5 is a great amp, too! Very lightweight, lots of output. It is worth noting, however, you CAN NOT bridge the Pro-LITE 7.5. (The Pro9200 is capable of being bridged)

In both cases you can easily run them off a 20A outlet unless you start running sine waves at full output. If you keep it up long enough, the 20A breaker will give first. You will need to plan for DSP to provide alignment between the subs and whatever tops you are using. I've got a recommendation for that too, but based on my current level of punishment, I'll keep that under my hat.

I disagree. Have both setups with the same tops. The DBH sounds like a single horn loaded sub. The 118's sound full and round.

I think he meant the DBH is more in price.

I don't where his pricing comes from, but a DBH218 is (or should be) less money than a pair of TH118s.  Unless somebody is giving him a wrong price.

One for one the DBH costs more.  But the performance is also no equal.  Generally 2 TH118s is roughly equal to a single DBH218 (give or take what you are looking for)
