Audiopipe TXXBDC4 in a Tuba30 ?

#1 Post by djthunder » Tue Jul 30, 2019 5:43 pm

Just curious. I know generally car audio drivers are not the preferred, but these are built like tanks. Curious what people's thoughts are on these in a Tuba 30? I run a mobile DJ service, and today's hip hop music is seriously about equal to bass test CDs from 5 years ago. This kind of driver will take that kind of abuse. Thoughts? Opinions?

Here is a link to the specs:

Thanks :)

Those are a pretty beefy drivers for the price tag. I know a guy running a bunch of them in a hooptie see attached picture. If the driver has the correct specs and will fit in the enclosure than run it. I doubt the specs are in tolerance though.

You won’t get any more out of the cabinet design than the prescribed drivers but if the specs are in tolerance you may save a few bucks as those pipe subs are only like $100usd ea.i have AutoTuba plans in front of me, the Vas is 14l for the 10” audiopipe sub the AT requirement is 15-45l. The driver is 1” to tall to fit as well. Can’t speak about the t30 requirements.

It's too deep to fit.

Shouldn't be for the original Tuba 30 design. The updated designs, yes, but in the original design, as long as the Tuba30 is wide enough, should fit okay?

I wouldn't. Its response models very poorly in the T30.

I am not looking for a more efficient driver, but some advantages I could possibly see with the TXXBDC4 12", is the 1100 watt RMS power rating, and the huge Xlim. These drivers are designed to move a crazy amount of air.

Also, the power handling is attractive. I am aware of the law of diminishing returns, but one of the reasons this power handling number on this kind of sub is important, is because the music, especially for hip hop/rap events has changed. People who are running the EV ETX-18SP cabs are blowing drivers without clipping their built in amps. I think the reason why is because, particularly for hip hop and rap music, the bass line changed a bit more between the time the EV ETX-18SP cabs were designed and put to market, verses the last few years. The bass line in this music has been getting progressively lower for quite some time, but now it's effectively like a BASS TEST CD from 7 or 8 years ago, only it often goes even lower than those Bass Test CDs did. Low notes are held for extensive periods, effectively putting more power to the coil than originally expected. For a lot of modern hip hop and rap, the gap between RMS and music program is a lot smaller. We used to power a subwoofer based on 1.5 or 2x the RMS rating. You do that now with a hip hop track, and you are likely going to be in trouble.

What I find attractive about a sub like the TXXBDC4 is that it is designed with this kind of abuse in mind, with a huge Xmax, and a 1100 Watt RMS rating, a super stiff cone, and good cooling, and a price tag of around $170.

For a Band / Live performance, where you don't need to deal with that ridiculous bass line, I would not see any benefit, other than if you like heavy things...LOL (the driver is about 30 lbs.)

Just looking for possible solutions for current problems. But also looking for input, as maybe there are reasons this would not work, or perhaps there are better solutions.

Also keep in mind, I am looking at the Tuba 30, because I've already built a pair of Tuba 30's before, loaded with the Eminence Definimax 12 at the time, then owned a pair of Titan48's. Finally got to old to haul those around, so went to a set of 4 Bass Reflex 18" loaded cabs... and coming full circle and missing the output of the Tuba30s...LOL... Considering just going back to a pair of Tuba30s, maybe keeping one of the Bass Reflex 18" cabs for small gigs.

Darn. You are the man though. So I guess I guess I will check that one off.

With 17mm xmax they won't take 1100w, they're limited to maybe 400w at 30Hz. The huge xlim is a necessity with the very sloppy surround they use, which gives very little cone control. It's one of the reasons why it doesn't work well in a horn. The Definimax 12 was OK in its day, but only had 6.2mm xmax. That was decent enough in 2005, not so much today. With 13mm xmax one Lab 12 equals a pair of Definimax 12 in maximum output.
