I'm in process of sloooowly upgrading my HT in my living room. Eventually I will have a more dedicated room in the basement but that is years off.
On to my question.... My entertainment center takes up a whole wall. It doesn't go all the way up to the ceiling. On either side I have approx 5.5 cubic feet to play with. Is having subs up that high (7.5 ft.) have any negative effects? I will reinforce where they sit so they are sitting solid.
I was thinking about an ABC enclosure built around the Dayton 10" HO DVC. Seemed to model pretty well in winisd. I've built sealed, ported and one 4th order bp before. Wanted to try something different. +-2dB from 24-80Hz, -3bB @20Hz and -10dB @16Hz. I'll have a HP filter @ 18Hz to keep excursion down. They should play around 105dB each with 200W each. The enclosure will be approx 2 cuft between the two chambers plus port size which I haven't figured in yet. I should have more than enough room.
Any thoughts would be great!

Other than transmission of more sound through the ceiling rather than the floor, there should be little difference at the listening position assuming a crossover in the 80 Hz range.
That won't be a problem. They'll be crossed between 60 and 80Hz.
Now that I think about it, I hope I won't be transferring too much into the shelves making everything rattle. Should I couple and try to keep it as rigid as I can or decouple and try to minimize vibration?
Coupling the sub enclosure to the top shelving support will add it's mechanical vibrations to the acoustically generated shelf vibrations. If the sub is well braced, that shouldn't make much difference.
Too many unknown "moving parts" to predict what's going to rattle- often times the most annoying "sympathetic vibrations" come from stuff that is quite distant from the enclosure.

What I was thinking I could do is attach a price of 3/4" or 1" MDF across the top to stiffen it up and add some mass.
