I've got no dog in this fight, but I would caution you to not get just DBH218's. Yes they are incredible alone or in multiples, but if you get a call to do a show in a warehouse for 200-300 people you don't want to be hauling even one of those beasts in there to do the gig.

I might be inclined to do 3 TH118's with 2 SH46's per side but also have 2-4 DBH218 or maybe 2-4 TH221's if you really want to dig. Run the deep subs when you need it and cross it over into the TH118's where they are more efficient.


With a rig like this you can do 1 over 2 SH46/TH118 for a small club or do the full monty for an outdoor thing with a couple thousand punters.

I’m pretty sold on 4 BC215’s center arrayed with 2-3 SH46 over 3-4 TH118XL per side. A SH46’s tipped over a single TH118XL per side for DJ monitors. I’m wondering if a single stacked/flown J7 per side might be an appropriate option for larger outdoor events.

As far as scaling up goes I’m wondering if a single stacked/flown J7 per side might be an appropriate option for larger outdoor events. I’m curious if a single J7 *really* needs 4-8 BC215’s. That seems like a lot of sub for a single J7.

I need to contact my local dealer to see if I can hear some of these combos.

As Ivan essentially said, IF you're doing a gig where you need to run the J7s at full tilt (big IF) - then yes, you'll need that many subs.  J7s have a lot of output.

For smaller events - you simply turn down the J7s and don't bring the full number of subs. 

What about J7s and BC215s as your main system, and something lower cost for small events - single SH46 over single BC215 per side, which could also double as awesome booth monitors.  No need for TH118s. 

For really small events - just take a single subwoofer. 

If you have really really really small events - a single TH-Mini and some Go2 mains is hard to beat and not expensive.

That’s a lot of sub output. But, I’ll bet that set up would sound pretty effortless when dialed in.

I would stack 4x TH118’s per side with the J7 atop the TH118’s or flown (not always possible) and center array 4x BC215’s. Is this enough sub for two J7’s?

If you are talking about just TH118s, then a "good target" for Dance music events outside would be 10-12 TH118s for each J7.

I know it sounds crazy, but that is based on my experience

That DOES NOT mean that you need that many for a particular event, just because you are using J7s.  You would be surprised at how much area you can cover with 1 J7 per side.  Especially when quad amped.

I’m looking for 120-125dB at 50 feet.

This is where DETAILS/specifics really matter.

When you say 120-125dB, what time response and weighting are you talking about?  Is that just the subs, or the subs and the tops?

It makes A HUGE HUGE difference.  I have measured quite a few events in which the difference between A slow and peak is 30dB or more.  Some 40dB difference

Adding 10dB worth of subs gets expensive, 30dB is a couple of zeros difference in price.

I know that you have an idea of what you are looking for, but a simple number (especially in SPL) can be pretty worthless to others, who "assume" it means something different.

For example 2 TH118s per side will give you your SPL requirements in peak output, but if you are looking for A slow, then you need to be looking at around 200 TH118s PER SIDE.  That could really affect the budget-especially when you talk about the extra amps, cables, trucks, distro etc

Umm, you serious about that? That there is a lot of hearing damage potential.

[Jeremy Young]

There’s 24dB of loss through the inverse square law; from 3.2’ away from the source (rated peak) to 50’ away.  So if you need 125dB (hoping this is a peak number) you need 150dB from your source.  Even the J7 stops at 147dB.  You’re into the J4/J6 territory, which is usually a good moment to reflect and reconsider your expectations. If we go with your lower number of 120dB at 50’; the J7 can do it; peak only. 

[Tim Weaver]

Deafness. It's whats for dinner.

[Craig Hauber]

then you need to be looking at around 200 TH118s PER SIDE. 

What would that be in Matterhorns?
