DJ Rig and self power

[LelandCrooks]

Over the weekend I provided the PA for a wedding reception for a friend of my son. I think it's the first time I've had anything out that was just dj use. Always for bands before.

2 t39's 24 wide, 2 dr250's run off a digmoda DDC520. 500w sub, 250w top capable amp. I ran it in mono, took his laptop feed and ran it to 2 right inputs on my board. I have another setup with this same amp in 20" wide t39's, but the 24's are better. One of these days I'm going to pull the 520 amp in the 20" t39 and install it in the other 24". That way I'll have a stereo rig with the 24's, and use the t3910's and other DR250s for extras.

Smokin' I believe is the appropriate term. The dj had been in asking me about building him a rig. About 2 minutes into the dance he told me to build for him exactly what was running. Didn't hurt that setup took all of 5 minutes, including me carrying in everything.

I left at midnite, I understand the party went on til 4.

Leland,

Exact setup I was looking to buid (24" T39's and DR250's). How did you come about at 24" for the T39's? Was it sound, or easy of moving around? I have a chance to go 30", and room to load in and out of a vechicle. I hear often T39's at 20", 22", 23"..etc. Did you wish you had gone 30" or even 22". Trying to settle on width, hopefully 24" will be spot on. At this point not being able to compare A/B, suggestions are paramount.

Also, I like the idea of the DR250's. Knowing that it will take more effort to build verse's OT12's or OT15's. But, I have the skill's to pull it off with the DR's. How did you decide on the DR250's and not OT's or even the DR200's or DR280's? Just curious as to your choice of Cabinets and Size, would be helpfully.

I too would be working with Live Bands, and also from time to time, DJing, as yourself. Room sizes from 100 to 350 People. Sometimes outdoors, but not too often.

Thanks

Way back in the dark ages, DR250, DR280, tuba 24 and tuba 30 were all that existed. So my first cabs were DR 250's and tuba 24's. Since then I've built every iteration except DR300's.

Nothing has as of yet touched a DR. Otops are good, omni's are good, Jacks are good, DR's are another level altogether.

I originally had 4 t24's. When the t48 came out I replaced them. The switch to t39's is fairly recent, and I'm glad I did. Much more manageable. I first built a pair of 20's. I mostly did the 24's because it's such an efficient use of plywood. The difference is noticeable. I much prefer the 24's. I believe it's the best compromise width for 39's and t48's, in terms of performance, size, and manageability.

Nice! I'd love to do a powered system like this, but I love having the subs out for the girls to dance on. Wouldn't want them getting anywhere near the amp/cables on a powered setup.

Are you going to start offering the amp by itself?

Thanks for the help, Leland. Since the day I have started here, 1 week ago, I have read so many post, hours and hours worth. It seems that DR250 and T39 24" is a common theme. Something I will look forward to building. Plus as you stated, "I believe it's the best compromise width for 39's and t48's, in terms of performance, size, and manageability".

Just how many years ago was that?

+1, I love it when the cutsheets turn out well.

I also really like the idea of the Digamoda amps (I'm a sucker for simplicity), but they are out of my price range.

Out of curiosity, they mount into the horn path, don't they? Can you do that with other tubas or titans? I always thought mounting a plate amp in the mouth of the horn was a bad idea...

Well, yeah it is. I did the math and the losses in volume are pretty small. I mount them fairly low on the back side so I have a wider path to install them in. As far as blockage, nothing is over 3" high, which is invisible to bass. The loss of volume is all that matters.

7, maybe 8.

As soon as user configurable software becomes available.
