Yes that was exactly what I was thinking but Brandon spec'd a longer overall enclosure than what Kevin built.

But yes that's pretty much what I was thinking but with two PR's one on each side dual-opposed to cancel out all that inertia.

I would not recommend this orientation nor would I recommend pairing only two PR's with two HST18's.

Would there be an additional pair of PR's on the other end? It could work if you had another two PR's on the opposite side.

Yes, haha forgive my absolute lack of MS paint skills. I meant to label that as 2 PR's on each side for a total of 4 PR's with the HST's front firing. My bad

Ah okay. So yeah that might work out.

What kind of volume are we working with here? I'll do some sims for you.

Frikking huge if I went that route. But i need to measure here in a little while to see. anywhere between 18 cuft to 25cuft if I spanned the back of the couch, went 18 inches deep, and made it a height of 40 inches to fit the PR's stacked on the sides. It aint looking too good to get it much smaller than 18 cuft going this route.

Hmm yeah. 18cuft is gonna be pretty large. It will work though. A quick sim with the PR18-2100 nets a ~14hz tune but the PR's run out of excursion with 1,500w input. Lot's of Xmax on the HST18's left over which isn't necessarily a bad thing.

Funny I am going to be building a Sunfire like sub in a few months. I have a lot of scrap wood and thought it would be nice to have a small subwoofer for shiz and giggles. I was looking at the either a SA-8V2 and custom 8 PR's or possibly going to a 10 version. Although I would probably stick with the SA line up because it is easier to get PR's with more Xmax than a X series. I just wish I could find a small plate amp for it. No worries though as an Inuke 1000 should be fine on the little sub. (8 version)

That being said I dont know what kind of limitations you have Beast but what about 24 PR's for your setup?

Possibly get away with a pair of them with a pair of HST. I have not simulated this but just a thought.

24" PR's would have to go in the same space, on the sides of the box, so I could do that and get away with 2, but that makes the box even wider, which is not going to work. Honestly I am almost dead set on just another sealed near field for the two HST's. I know, not all that special, but it is really all that will fit in the space, without tossing the rear row and riser so far back into the room that there is literally no room to walk (Or throw darts) in the rear of the theater Gotta make a little sacrifice here as the PR build is something I would REALLY like to do, just not in the cards.

When you dont live in simulation land sealed is terrific. When your busy only looking at simulations it seems like sealed is such a waste. So I think you will be just fine either way.

I don't need a sub. I have plenty. Heck, I'm shipping off an old one now. ..but I have such a strong urge to do this too! Heck, if there was a good long through 6" and PR's and tiny plate amp, I'd probably be pushed over the edge of sanity :-D

i thought you had something like 30 drivers powering your bass. do you think more spl from the p.r. system would really be worth it?

Not sure what that quote was from, actually.... BUT I ended up with a dual sealed. I tried to look at ANY way I could do PR's on this setup, but I just don't have the space between rows to make it happen. 12 cuft. for the big boys, as narrow of a box as I could manage, at a measly 14 1/4" deep. Will make a great bar for the second row and brutal destruction for those ballsy enough to sit in the front row:

Yes, that box went Westerly, gotcha

To supplement, I did this little guy. Nearfield, for fun, with the HST's. Seems like a great trade-off to me
