Looking great! I love the brace work. Too bad most of it won't be seen. :(

How are you liking your rig so far? Have you got to fire it all up yet?

I've been using the omnitops for a while now, probably 2 years, I love them, they incredibly clear, clean, and open.

I don't have the same experience with the titans. I built two of them back when I built the omnitops. 2 titans aren't enough for most of what I do. I have a stash of double 18 beasts that I built years ago, pure brutes, and that's what I've been using. I just now got two more titans built, for a total of 4, so that should be enough for most of my gigs. I do know that the titans perform like a totally different animal when V coupled. two titans V coupled will keep up with 2 of my double 18's. Most places don't have room for V coupled titans, so I've been using the double 18's. I have a gig Friday night, a room I am very familiar with, and a room that eats bass. I plan on trying it with the new titans. We'll see how it goes.

I like the brace idea. Nice albums. How are the speaker stands working out for you? Are they stable? I imagine they are their own cab cart as well, huh?

Thanks for sharing.

I never used the speaker stands. I had them almost finished, then hurricane Ike hit, and a huge tree fell on my house. By the time I got all that taken care of, the speaker hoist project had lost priority. Then my typical sound job changed, from churches to clubs, the speaker hoists didn't seem like the way to go. I have a total of 4-12 omnitops per side now, 2-212's and 4-112's, so for big events where I'll be using all 8, I'm looking at building some lightweight A-frames to hang them from. something that would be stable outside in the wind.

Takes me back to Scout days. :hyper: Between running the wilderness survival courses and general teaching, those A-frames are burned into my head. :lol:

didn't work out. Titans wont keep up with my double 18's. They are impressive in that they get the most out of the available AC power, since they used 1/4th the power of my double 18's, and they weigh considerably less, but when the band gets cooking, they just can't keep up. Three titans would probably keep up with 2 of my double 18's, and I know that two titans v-coupled come a LOT closer, but they take up too much real estate v-coupled. Titans are impressive but just don't fit into my usage.

well, They are beautiful, regardless of how they sound. Since you have a total of 8 omnitops.... its no surprise that 4 titans cant keep up I guess? What type of venue/music do you cater to?
Built:
2x Tuba 30s delta12lf loaded (gone)
4x Otop12 d2512 loaded
8x t48s (18, 18, 24, 24, 30, 30) 3015lf loaded
2x AT (1 mcm, 1 gto 804)
2x SLA Pro (dayton pa6, 6 goldwood piezo loaded)
1x bastard XF208

2x OT212 (delta pro 450a loaded, eminence psd)

I've been using one 2-12 OT's on each side as in the photo. If it were all 8, the subs would be covered completely up. Rock band in medium sized club. The only club I tried them in is hard on bass. I've done the club many times with the same band, and the room eats bass. Had they done well in that environment, then they'd be good anywhere. It was basically an A-B test, since the only thing I changed was the subs. This is my typical application and they just don't fit. Not saying anything negative about the titans, they just don't compare to what I have been using. If they were all I have, I'd build some more and then it would be good. If I could v-plate them all together, they do well, but not enough room for that.

Wish you were closer to compare your 24" to my 30". They're bigger, but I've never had any complaints about a pair keeping up with 4 OT112. 6 OT112 seems a better match for me, and I like the kick to hit pretty hard.
Qualitatively, do you find any difference between your 18"s and the Titans? Are the mixes with Titan's cleaner in the low-mids?

Yes, the mix is cleaner in the low mids with the titans. Every gig I've used them on, the bass guitar sounds better, is much cleaner. I'd say I wished I could compare mine with some others, but I can compare them with each other. I built a pair about 2 years ago, did a lot of testing on them. Then I just built this pair, and I've compared them all, and they sound the same, same output from all. If there was something wrong, I don't think it would be wrong with all of them. I also tested them side by side, adding them one at a time, and every time I added one, the sound got louder, suggesting that they were all in phase. If I had the option of putting them all together, I think they would keep up, and if I put them together v-plated, I'm sure they'd keep up, but those setups are not always an option.

That's been my impression with my mixes vs other 18" loaded rigs as well. Things just work, I don't have to fight the bottom end of my mixes with EQ to try and clean things up. After spending a few years mixing on my Titans it's a very apparent difference when I have to use someone else's rig.

Not thinking you've got anything wrong with yours. If everything's the same across the board and they begin to compete with the double 18"s, they're good. What I was thinking was if yours are 24", the charts show the 30" may make up for the difference you're hearing with your double 18"s. IIRC, it was mostly in the bottom end you found the 18"s to pull ahead, and that's also where the v-plate makes the most difference by extending the horn and mouth area. You might find a pair of 30" wide would keep up with your others. If it's not an issue of max output where the 15" runs out of steam long before the 18"s, then I think that's very plausible.

You might be right, going to 30" might do the trick. In my tests I found that 2 double 18's vs. 2 titans 24" were right together at 80hz, but the titans were down 4db at 60hz. With the v-plate, they were the same at 60hz and and same at 80hz. The v-plate had no affect on 80hz, but a dramatic affect at 60hz. I did a few outdoor shows with two titans v-plated and 2 OT12 on each side. One v-plated titan pair with a pair of OT12's on each side. The titans kept up just fine. In my club test, I had your typical club setup with a pair of titans on each side standing up side by side with a pair of OT12's on top of each side. I ran the titans two on each side of a QSC PLX 3402, which is rated 1100 watts per channel at 4ohms, so since the titans go 10 ohms, which would be 5ohms per side on the amp, there should have been 450 watts going to each titan, and I had to have the clip light lighting with each kick hit to get it up to a usable level. Just not acceptable. Sometimes I need to set up the subs on each side. I have to run two amps with my double 18's since they are 4ohm, but the bottom line, convenience is great if the results are acceptable, which in my case, they aren't.

Maybe you should give some big-iron Class AB a shot on those T48's, or try running one per amp, like you did the 18"s. IIRC, RonK was saying he's not so impressed with the newer switching amps on bass material when you push them to their limits. PLX's are light and letting them coast individually might do better than loading up the amp. I'm running two at a time off a channel of my PLX3602 and not having any issues.

If you were up to it, you might try building a sample 30" cab. It took me under 3 sheets of 4x8 ply and about a week to crank one out. You've got the drivers to spare and you could probably get some money on the forums for the unloaded cabs if they did the trick. The 24" still isn't a slouch, just not quite as loud as you're used to. Yours look good and uniform, easily saleable.
