titan 48 vs. double 18

I think that there are isolated cases where a 2 x 18 will beat Titans, but not in price, weight, or other means.

That said, I enjoy seeing the data from these comparisons and tests shared - and also the respectful way that it is received. Thankfully, we don't have flame wars on the forum.

I'm not done with them. They aren't broken in yet, and I've only done one actual concert with them. I know there are some highly respected front loaded subs with processors that beef up 50hz with eq, so that should not be a problem, adding a bit of low end to the titans. I'm curious if others tweak the titans with eq on the lower end? This was to be part of a very efficient lightweight rig I can set up by myself. That is still a strong possibility. The one gig with the pair , one on each side of a PLX2402 was just to see what they would do with that, and if I let the amp's limiter light blink they actually punched pretty well. From now on I'll use one of my PLX 3402's, should put out about 560 watts at 10ohms.

also, I did a 2 on 2 test, 2 titans is all I have so far. I'm sure a 4 on 4 test would be drastically different, but 2 on 2 didn't get the low frequency extension to measure up. Again, I'm a fan of the Titans, actually a one on one test would mean 2 titans against one double 18. I was comparing one titan with a single 3015 to a double 18 with 2 eighteens.

Absolutely. I tweak the lower EQ on both Titans and Tubas in small stacks, you almost have to. If you look at the SPL for a pair of T-48's it's about 10dB down @ 40Hz and 7.5dB down @ 50. I wouldn't necessarily recommend pushing another 10dB @ 40, but there's no reason you can't bump it more than it's normal response.

The 4 cab chart shows only about 5dB down @ 50 and 6dB @ 40.

someone else reported that their tuba's kicked in, night and day from one gig to the next. I got the titans out again last saturday night, and they rawked. Big and fat. I again had them center coupled in front of the stage with monitors on top. One OT on each side this time. I had to cut the titans back a bit, they were outrunning the omnitops. I do think that 3 titans would keep up with 2 OT's on each side. Of course with 3, you'd have to stand them up side by side. I ran the titans one on each side of a PLX3402 in stereo mode. They seemed to like that.

Understanding there's not always room, have you tried the V plate yet? There's your third Titan and it's virtually free.

I think the V plate will come in when I get some more BF speakers built and do away with my current big rig. I'm thinking 4 OT's and 4 titans (titans V plated) will do anything I need to do. Still working on a plan to get the OT's elevated.

I meant 8 OT"s (4 on each side) and 4 titans

Makes sense, I was thinking 4xT48 would be slight overkill for just 4xOT12.

I set my T48's up this weekend with the V-plate (thanks Leland) and OMG!!! I was idling 1/2 of the CE1000 at <10 Watts playing some Gato Barbieri (que pasa) and the bass response was awesome. Clean, clear and thunderous.

I had set the system up in the driveway and the neighbors for blocks were looking to see what the rumble was. My amps didn't even crack a sweat.

I can't wait to finish the DR250's to put on top.

Glad it fit. I slapped that thing together in about 15 minutes. Not exactly an example of my best work. I'd never tried it out.

My titans may not be ready yet....But I've used lots of horn loaded subs and love em. When they couple together outdoors, watch out

.
Double 18's do wimp out over distance quickly as do most Direct radiating boxes. The horn acts like an impedence matcher coupling the pressure from the speaker inside the horn, to the outside world. In addition many horn loaded designs have sealed compression chambers or speaker chambers that help keep the speaker physically together due to air resistance fron within. Most direct radiators, especially double 18's, (or god forbid Nexo!) are either ported or wide open. The Double 18 has no back pressure to help prevent over excursion so they usually just blow pretty quickly or start falling apart. I never blew an 18 in any of my W bins over an 8 year period (non ported version) before selling them to move.

Indoors the double 18 has a "sound" that people like.
Correct me if need be.

Edit: Spelling.... if I could only type as fast as I think..
