...they weigh 185lbs each. they appear to be well-built, but still i worry about the bottom sub supporting that much weight...

any experience with stacking heavy subs? i seem to remember bosso stacking his ravens, but i don't think they were this heavy...

Why stack them? Place them separately to even out room modes.

If you have great results why mess with it? The only thing you gain by stacking is more output but you give up the smooth freq response. But if your curious about it just go for it and tells us your results. To me seems like alot of hassle for nothing.

I don't know how you define "great results". If you're goal is just maximum headroom, then stacking is the best option. However, (IMO), flatter frequency response across more seats is a much more useful goal. I would sacrifice a few dB of headroom for flatter FR, all day, every day. But hey, they're your subs... do with them whatever you want.

Haven't I ever wondered "what if"? confused.gif What if.. what? What if I stacked my 3 Submersive HP's? Here's my FR now:

Subs, no speakers, Audyssey XT32, 80 Hz crossover:


Subs + Speakers, Audyssey XT32, HP Prgm 2:


If I stacked them in the front of the room, this would be my FR with +9 dB of headroom:

Front:


I don't need the headroom. I'll take the flatter FR all day, every day.

well...first off, i want to thank you guys for yer input...good advise as always

but, with all do respect, i didn't ask if i SHOULD stack my trinitys

believe me, i've had them in many configurations, along with dual mbm 12's...my question focused on my concern with stacking such heavy subs


i will probably end up leaving them in the position they are currently in...they sound and feel great...but you never know...in my room, my setup, stacked trinitys in the back corner just might kick arse

I can only offer analogous info as I don't own any trinities, but if the sub is well made they can generally hold a lot of weight. For example, people have stacked SVS PB13 Ultra's three high, and they weigh 155 pounds each (so 310 pounds stacked on top of the bottom sub). I've also used my Ultra's and my old PB12 Pluses as impromptu step stools to adjust my rear surrounds on occasion, and I weigh 260 pounds. I haven't heard of anyone having any issues and the sub looks pretty well put together, so I'd *guess* that it should support the weight of another Trinity stacked on top. Of course, that is just a guess.

Have you tried asking Definitive if they have any positions on the idea?
