Any probs w/this combo: shuttle6 in to 2 cabs (TB153 and genz 12t)

corba · #1 05-08-2011, 08:51 AM

I tried a shuttle 9 on the TB153, it sounded good.

I tried a shuttle 6-12t combo, it sounded fine.

I tried shuttle 6 12t+TB153 (both cabs 8 ohms), it sounded GREAT.

I know the TB153 is said to be best solo, but perhaps only due to the power increase, the 12t+TB153 sounds best IMO.

am I missing anything from phase cancellation (both cabs have tweeters too), spectrum clash or other imbalances? If I understand ohms law, the same wattage is going to both speakers. I did smell a little heat/break-in coming off the 12t coil after a lengthy jam (w/drum machine also in circuit).

I think due to the power boost @ 4 ohms and maybe combined with the fact that I'm mounting the 12t combo on top the TB153 for better projection, I will gig with this combo, unless anyone sees any problems with this config. thanks.

otherwise, I'm tending to go w/my ear on this...

Anything sounds better from close when louder. Your best bet is the 4 Ohm TB153. Out in the room, combining the 12 and TB153 may cause problems.

Should not be a problem.

Do you believe that mixing a 3 way 15 and a 2 way 12 (both 8 Ohms) is a good idea when starting from scratch???

BTW, not trying to be snarky and I agree it'll "probably be OK", but not optimal and in some rooms could be problematic.

I'm curious of agedhorse's response, but I'm not starting from scratch, i own these components currently. thx.

I'd guess the nEARful crowd would not recommend mixing these.

I wondered that when I read how a few are combining their 15/6 cabs with a 12/6 cab, or something along that lines, but def they were stating a 15 + 12 cab. I thought someone would chime in to say that's a bad mix.

Then again, I have not read exactly where a TBer has done this and loved it-hated it and/or what's happening beyond the stage area when they've done this. Maybe the question gets answered in one of those fEarful/nEarful threads, I've not read those completely thru in awhile. Lotta folks are in the if it sounds good; use it mindset.

Combining a fEARful 12/6 with a fEARful 15/6 works because the cabs were designed to work nicely together.

I'd say that if the OP likes the sound, and it works for his application, and if he feels he will need two cabinets in some situations, then why not?

Personally, I always have bought 8 Ohm cabs so I can use two on outdoor festival, or arena gigs. For the last six years, my rig has been a 700RB II driving a Goliath III 410. Plenty for any gig I do, really, but on a couple of fests, I've stacked a Dr Bass 1260 (12" 3-way) on top for the extra coverage, and haven't detected any noticeable phase issues at all.

I'm just not all that anal about it. as long as i'm playing quality gear that's not grossly mismatched, and all my notes from low to high are reproduced cleanly and clearly, I'm satisfied. I can use EQ for frequency corrections when needed.

I am a big fan of the fEarful, and while I don't own one, I do have a Carvin LS1503 with a Kappalite 3015LF that I'm using on my "self carry" dates.
I think if I was going for the Avatar TB 153, I'd try to find a good 115 to sit under it. Maybe something with a Kappalite 3015 in it.

If you already own both, no biggie at all to pair them. The 12 on top may make it easier for you to hear yourself. Overall though, the 12s contribution to the room will be overwhelmed by the 153.

And they would both be crossed to their (identical) mid drivers at the same point, with the baffles reversed to keep the mids lined up nicely.

Personally I wouldn't mix those two cab's as they are unlikely to be voiced identically. So the EQ that may be necessary to fix an issue in one room, may not play nice with one of the other cab making it tough to find 'center'.

FWIW - the 12.6 and 15.6 sound good together not so much as they were designed to work together - the relative efficiencies of the cab's are WAY off with the 12.6 being the less efficient cab. Power handling on the 12.6 is also limited in comparison. GB wasn't really thinking about those cab's as a working pair from the start. The reason they do work together as well as they do is because the cab's are voiced identically. So your EQ tweaks have consistent results.

The additional volume of the 12.6 is going to be noticible but not really that big a deal - what will make a difference is having that 12.6 in cube format, stacked up high where it is easier to hear on small stages. Then again, with small stages often comes a small room so often the 12.6 by itself can be overkill... I need roughly 4 to 6 feet away to feel like I'm getting a good feel for what is going on using 12.6. I perfer 10 to 12 of course...

From what I read, a number of guys have done the 15.6/12.6 stack because they can; then they go back to the 12.6 when they don't need the db's of the 15.6 ...

I ran one gig with a pair of 12.6 's - and with even 300 a side (WT800) - it was complete overkill for me - outside! (that was against mic'ed drums, a Fender HR Deluxe and Fender HR Deville 4x10).

To net all that cr@p out ... adding the GB 12 is going to be marginal at best, troublesome at worst. Given the much higher power handling of the Avatar, you also run the risk of smoking the 12 as you may not hear it complaining under the roar of the Avatar... IMO - keep the 12 for use when you don't need the db's of the Avatar. Consider a larger head to drive the Avatar harder ... YMMV

question for aged horse or anyone else - when you are using the two cabs and thus going from 8 ohms to 4, are those two cabs both connected directly to the amp (the Shuttle 6.0 having two outputs), or is one of the cabs connected to the other cab? And can you briefly explain why one is the right way and the other not, ohm-wise?

Thanks!

My assumption is that everything is parallel, both amp and cab.

So connecting two 8 ohm speakers will yield 4 ohms

chuck3 · #14 05-08-2011, 02:17 PM

"parallel" meaning you're using both outputs on the amp, one speaker plugged into each?

Sorry to be ignorant of this terminology, which I should know.

You can connect them any way you like (amp>>cab>>other cab or amp with separate out to each cab). If both cabs are 8 Ohms you'll get a 4 Ohm load with half the power to each cab.

.

I believe I've probably posted at least fifty times that virtually any two cabs together will sound better than either one alone. This would be a case in point. The question is which would sound the best, two 12T, two TB153 or one of each. I suspect two TB153, but if one TB153 and one 12T is what you've got then by all means use them.

Marty Forrer · #17 05-08-2011, 03:08 PM

Go for it. I use a Shuttle 12T on top of a SWR 4x8.... works fine.

No explanation needed.....either way you hook 'em up is right. It's identical.
