Personally, I prefer the look of two stacks. :mrgreen:
haha touche, I only ever got to hear 6 in action. Now I only possess 4 of them, which is more than enough for the shows I do. FWIW there was a shootout between the DR200's and DR250's a long time ago and the DR200 unanimously won out. It wasn't a beating, IIRC it was just a subtle smoother dispersion in the mids but everyone heard it. Please make and update a build thread when you start this project, a project this size is what we live for here!
Built:
17" width 10" driver Autotuba
2 x 29" width dual Lab12 Tuba60
6 x DR250 2510/asd1001
In progress:
2 x DR250 2510/asd1001
For best results, point the loud end of the array towards the audience

Just out of curiosity, what size crowds do you anticipate? 8 DR's is a lot of horsepower. When the homepage says it can handle 2000 people it means it. These cabs are no joke when it comes to output. 8 cabs are a bit of work, you better get started on the asap to get these done! BTW I still think a 150w amp is too small for these cabs. Headroom is what makes these things sing, clipping is just bad news to the ears. I started off with a smaller amp on these things (inuke3000) and they got loud and all but it wasn't until I got a bigger better amp that these things came alive and almost scared me on the output.
It's not-so-much the head count of the crowd... The venues for the performances I do sound for are always a little obscure. My family is a boating family and my dad sings and plays 12 string. He's slowly created a name for himself in the boating community and is starting to play at a lot of yacht clubs. Sometimes he plays solo, sometimes uses drum and bass backing tracks, sometimes a 4-5 piece band. Typically he sings to an audience of people rafted up in their boats. Sometimes they play off the back of the boat, sometimes he sets up on a dock, and occasionally he plays indoors too. Sometimes the audience is upwards of 200-300 feet away at the deepest and other times I need to get sound across a wide but shallow area, maybe 60' deep, yet 300 wide. Bruce made a comment on another thread a couple weeks ago when I naively mentioned 100' speaker cables... something about that I must set up on really large stages. Well, kinda. I'm setting up on a 200' dock in a couple weeks and hope to cover 200 feet wide and 200 feet deep on rented QSC gear.

I trust your opinion on the amp selection, yet I also trust Bruce's more conservative recommendation too. I do know he sets his limiters and highpasses on the conservative side. I also appreciate and trust Joe's experience with his DR200's and from what he's saying he has his limiters set at 35v and has never pushed them into limiting. So, I have 3 valid opinions ranging from 100 to 300 watts per channel. I'm really curious what Yoda himself will recommend.

I see, 8 cabs will definitely give you lots of options to cover the many different layouts.

That will give you an idea for coverage. I did a similar gig about a month ago with some rented yorkville gear. 2 15" tops and a single horn loaded sub covered that entire bay nicely, sound travels really well over water. Loading 1000 lbs of gear onto and then out of a boat wasn't so much fun.

Sheesh, I can't think of a better life than boats and PA systems and a gigging Dad. Good form. ...I'm writing this from a caravan in Wemyss Bay on the Clyde (Scotland), so my appetite is half getting salted, as much as an arm chair sailer can get anyways.

It's be nice to see more pictures/videos of your setups.

The advice and opinions varies quite a bit. I don't suppose it would be asking too much of you to expand on that a little? :fingers:

Bruce says 30v, J says 35v. I wouldn't disagree with either. I wouldn't cheap out with an amp that will only do 30v cleanly, as that won't give any headroom and it won't offer additional protection.

Thank you Bill. I appreciate it. I picked up an Ashly NE8250. We'll see how it does.

What a beautiful venue! Was it live or recorded music?

I hear ya about schlepping all the gear. I've put a lot of thought into creating my system as compact and light as possible for that exact reason. As impressive as a rack full of amps looks, it's just not realistic to load the typical heavy and cumbersome amp rack or storage chests full of cabling from a 4' high pier or rocking dock into a transport boat, to then put it in another boat, and possibly from that one to another... and then have to reverse the process. All my rack-able gear is in manageable 4RU rack bags or plastic wheeled Gator Gear racks. Other than being manageable, it keeps the gear from beating up and scratching the boats too. I'm doing the DR200's in 1/4" ply and the neo drivers are only 2½lbs, so they should be about half the normal weight. Not sure there's any fat to be trimmed off T39's though, other than choosing the lightweight 3012LF Neo driver.

I made a typo ☹️
My DRs were limited to 25v it was my old T24s that we’re limited to 35v
I still have never run up against the limiters, but thought I should make that clarification

WOW! I certainly do appreciate the clarification. Are you sure about that though? You set your limiter at roughly 78watts? And, they're so loud that you've never bumped into the limiter? That's pretty amazing. Are you sure that's not for the IPS150/tweeters?

Don't get too concerned about watts. We've all been hammered over the head with 1000 watt speakers from manufacturers for so long that we are actually starting to believe that it can't be loud without a lot of wattage.....those 1000 watt boxes NEVER see 1000 watts to any of the components - they are limited, just like what we do.....or they blow up just like ours will if we aren't careful.

You are right that I'm pretty conservative with my settings - that's probably why I've never blown a 12 inch driver in the 10 years I've been running these boxes....did have a compression driver crap out once - still not sure what did it, but I think it was because a capacitor blew up in the crossover.

Here's another way to look at it that has never been discussed, so I'll throw it out there.

I don't really worry about my tops very much when it comes to limiting for the simple reason that my tops can outrun my subs. Since my subs are limited and I know at what point on my mixer I'm gonna' start hitting that limiter, even if I'm on stage and running sound from there - I know where to stop. And I know if I stop inside my subs' limit - then my tops will be ok.

Of course I rarely run sound from the stage anymore.....been a couple of years and probably won't ever do it again as my band situation has changed. But, if you are out front - you'll hear if things are getting out of hand.

Not trying to dissuade you of limiting the tops, but rather I'd say if you are concerned - then set the limiter lower and see if you get everything out of your system at that setting - I'm guessing that you will.

Oh, and I agree to getting more power than you need.....you can't trust the power ratings on just about anything anymore....
