Title: 2 x TH118 (vs) 4 x TC2800 (vs) 1 x DBH218
Post by: Will Cash on July 27, 2016, 12:17:44 pm
Alright, I know I've been posting a few of these. Hopefully this will be the last.

I think our tops are going to be a pair of the RCF 4Pro 6001-A...

We'll be mixing live avant garde, electronic, DJ, and occasionally full band acts in non-traditional spaces on a Soundcraft Si Expression.

How would we fare with a pair of Danley TH118s as opposed to four TCS 2800s or ONE Danley DBH218?

Seems like we are going to spend a lot powering the Danleys properly... What are y'alls thoughts on this?

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.

Forget TCS.

DBH is 350 pounds of logistical hell, but it's a damn fine subwoofer.

2x TH-118 is the way to go.  Split them when you need to, add on in increments.

We stacked these by hand; managed to get a lift for the out.  The apparent scowl on my face is from having to stack twice.  "Oh sorry, we have to move the stage".

What is your AC distro situation?  If you can run 240v some interesting options are out there.

Actually it is 277lbs--just being "correct".

Stacking them 2 tall is not hard.  3 high requires some more hands.

4 requires you to put the cabinet on some cases-and lift it up.

Or use a lift.

It does feel like 350. Danley should check their scales :)

I'd love to hear what 4 subs to one top sounds like. I have 1 sub for one top. 2 subs would be perfect for me but it's working great so I can't justify the cost.

My subs just move from stage to storage when the room is used for meetings . But if I was travelling I'd go with TH118's. No question.

It's not my rig.  The tops cost a lot.  A Danley dealer can tell you; be prepared for sticker shock.

I have not used those RCF boxes, but I'll guess it's a good match and also that they sound pretty good.  You'll likely want to get to 2x TH-118 per side.

I have been using identical systems...one with a single DBH218...one with 2 TH118's.
The TH118 setup sounds much better IMO. Plus...if one goes down...you can still do the show.
DBH doesn't sound warm like the tapped horns do. I want to replace it ASAP with 4-6 TH118's.

Thanks everyone. Pursuing the TH118s...

Any advice on powering these knowing that certain venues may only offer 20A circuits?

I've heard that the Danley DNA amps come with Electronic Breaker Protection allowing the user to limit the draw per circumstance. Are there other amps you know of with this technology that would be sufficient for these subs? Cheaper the better for us....

Any professional large amp with a universal voltage input - Powersoft, Crown ITechHD 12K, etc.

If you plan to run 4 TH118s on a single amp (2Ω per channel load), you're going to need 208v/240v to get full output.  Better yet is one amp per pair of TH118 and 2 20A 208v/240v circuits.  With only 120v power available it will work but you will leave some output on the table.

One time in an extreme case I blew a 20A breaker on my ITechHD12K powering just a single pair of TH118 (4Ω load), but that's hard to do, and was a little hard on the Danleys (I've since gotten better limiter settings).  Logistically the TH118 is fabulous.  Small, lightweight, built-in dolly.

Yes, the Danley DNA 20K4 Pro is the right answer to your amplifier conundrum. If you get passive top loudspeakers, you can use two channels in the amp for them and the DSP to process them.

External Breaker Protection works really well. Tell it you have the amp plugged into a 20A breaker and it will keep the breaker from popping. Yes, this does limit the ultimate maximum output of the amplifier a bit, but it is not that obvious unless you are really pounding on the amp.

Likewise, the amplifier automatically switches between 120V and 240V modes of operation, so if you are clever you can run it on 240V when it is available, whilst falling back to 120V when you have to.

I'm the amp guy at Danley. I'd be glad to answer any questions you may have.

With due respect and not necessarily disagreeing with your suggestion, as the "amp guy at Danley", I'm not sure it's kosher to declare that your product is absolutely the right answer to the OP's situation. 

I can think of several reasons that other amps may be a better fit than the Danley in this case - integration with existing control systems, and power configuration being two.  If the OP will rarely have access to circuits greater than 20A, a high-power 4-channel amp isn't the right choice.

I think it makes perfect sense to suggest a Danley amp with Danley presets for Danley subs. Even if he doesn't use the other two channels it's still the best amp for the subs and will work on any outlet. Maybe not the most cost effective, but certainly the best option from an efficiency and limiter protection standpoint.

Well, it's against forum rules for a manufacturer to plug their own product unsolicited, and I disagree about a mega 4-channel amp on a 20A circuit. Why pay for 4 channels if you can't use 2 of them?  As much as I support the black box model, sub presets aren't rocket science and Danley has supplied them for other manufacturers' amps.

Since your tops are powered, you may look into getting the powered TH118s. You're going to need an external processor either way.

The powered Danley subs come with 2 presets.

One is a low pass @80Hz and the other has no lowpass.

So you can use an external processor to put the low pass where you want it

I always suggest an external processor with powered speakers just to have better control.  But in some cases it is not necessary.

The choice of amps would also kind of depend on the tops you decide to get. I know somebody here was using one QSC PLD4.5 a side, I think using 3 channels to power the TH118 and one channel for an SM80. That seemed like a pretty elegant arrangement to me.

For one pair of TH118 -

How would I fare powering each sub on its own XTI-4000 vs a single PLD 4.5?

I know it's not the right thing to do really, but what about a single CS 4080 HZ?

I would stay far away from the XTI4000 for subs. It doesn't have the power supply for any sustained bass notes. The XTI4002 was is better but still not great.

I've had really good results with the RMX series on subs. They're fairly inexpensive too.

You will be initially limited by your 20 amp situation.  Traditional iron amps won't work.  You need a modern design.

I have not used the IPR so I can't comment.  Maybe someone else can.

I have used lab.gruppen fp14000 on wall current in a demo situation very successfully for subs.  But that's a pro solution and priced accordingly.

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'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.

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.

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.

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???  :o  ;D  8)

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)

Whatever brand you go with, PFC really helps with circuit breakers, in my (somewhat limited) experience...
