Dual Def Tech Trinity Subs

[Below10hz]

Anyone else even considered this insane idea?

I currently have 2 Def Tech BP7000SC's that I have driven by an Adcom 555SE. I am using this system only for music. I am fond of organ music, which requires quite a bit of bass response.

I'm quite pleased with the two towers alone but I have a large space with a very high ceiling to fill with sound. As far as I know the Def Tech Trinity subs are capable of 10hz. Which other subs might compliment this arrangement?

My budget is 8K for all this. If I can go less that would be even better but I'm willing to go to either a HUGE single sub or do dual subs that are identical.

I can provide more details if needed. My HK 2-channel stereo is used as a preamp, it has dual sub (R/L channels) output.

Thanks very much,

the Trinity looks like a good sub, but I would turn to internet direct options if you are unable to get a really good price on it. Definitely get something else if you can only get the MSRP on the Trinity. I wouldn't pay over 2k for a Trinity, considering what you can get elsewhere.

Is the receiver that you are using a HK 3490 or 3480? That is what it sounds like. If so, let me know, you will have an interesting problem, just like me. I love bass-heavy music, and that is the receiver I have, the 3490. Problem is, even though there are two sub-outs, there is NO BASS MANAGEMENT on the thing. There is no internal cross-over! It might not be a problem for you, depending on your situation.

Some alternatives to the Trinity are the Seaton Submersive, The HSU ULS-15 quad drive, Elemental Designs new A7s-650, or the A7-900 if you want to go really massive. Some A7s-450's would also do the trick. Or some Epik Dragons. There is also the Rythmik F15. Any of these will be a far more cost-effective solution than the Trinity, unless, of course, you can get the Trinity at an amazing discount. I have some ULS-15s and Hsu ships them with a demo disc with organ music, and it is amazing- some subwoofers you can feel in your chest, but the deepest ones you feel in your stomach, that is what I found out with those.

Shady provided some great options. One more to consider is the SVS PB13-Ultra. http://www.svsound.com/products-sub-box-pb13ultra.cfm

Agreed, a very good list provided by all here..

In all my hunts for the best subs, as far as pre-built (Ive built my own)- no question in my mind the Submersive should be #1 to be considered. I'd put very very good money on it that said sub will outperform pretty much all other options IMO.....

Dual Submersives would be even better...

You will see alot of people came off very high quality products to move over to Mark Seaton's Submersives... Worth your time to check it out....

Don't get too hung up on all the "below 10hz" stuff, I have watched many chase that goal, and achieved it in the DIY community and in the end moved on to very good quality middle teens output, something that pretty much any of the subs mentioned will easily provide, depending on your room. Just my opinion...

Yes, I am going to look into all those options. I've been looking for the Trinity at a discount and can't find one. I was intrigued by it since it powered the digital organ in the church in NYC. I've actually been there during one of the performances and it was to say the least, quite amazing.

Yes, I have the HK 3485, the internal amp bypassed. Doesn't the sub itself have a crossover and you just set that and be OK? Seems not what I was thinking. I never had a sub attached so I never tried it.

Thanks so much for the info!

The Submersive is a terrific sub, from what I have read, but it isn't necessarily the best performer, although it certainly is one of the best in it's price range. The A7 900 would definitely best it in output, and it's supposed to have excellent sound quality too. It's caveat is, do you have a place for something so large and the ability to move around the 400 lbs behemoth? How would the Submersive stack up against a pair of HSU ULS 15s or Rythmik F15s? It is not the best without qualifications, as with any of those subwoofers; they all have a slightly different role.

As for the HK3850, I'm not certain about that receiver, but the newer version of it does not have bass management, so I doubt that it would either. What does this mean? Yes, you can use the subwoofer's crossover, but the speakers are still going to try to play the full range too, as opposed to being cutoff by the receiver. This is not an ideal situation if you are an audiophile bent on the purest sound, but it really hasn't bothered me much, although I would prefer not pushing my mains to try that kind of heavy lifting at those frequencies. It is probably not going to be a big deal to you, and I don't think you would notice unless you were really listening for it. All this depends very much on what speaker you are using, of course.

Either way, can your speakers keep up with the massive subs you are planning on adding to your setup? You will need some serious speakers to not get overwhelmed by something like two Trinitys. By the way, if you are really going for that massive, deep pipe organ effect, the A7 could certainly do that better for cheaper, if you can accommodate its massive size. You might also call or email Mark Seaton and inquire about his Terraform design.

By the way, you might also consider tying your subs to the left and right channels instead of the subwoofer outs. This may make more sense if you are going to have two subs, and if you are going to place each sub next to a speaker.

One more thing- if I were you, I would take a close look on how you intend to power two large subs, electrically speaking. Two or more large subwoofers may be too much for the electrical circuit they are on, especially if it's only 15 amps. I wouldn't put any of these on the same circuit unless it was 30 amps.
