The triple woofers are 800W, each mid is 75W for a total of 300W and each tweeter is 25W for a total of 100W. Hence 1200W.
House of the Rising Sone Out in the mid or far field Dedicated mid-woofers are over-rated

Trevor, Really like the folded QRD designs. Think I might try a building a folded design using foam/board the way you did. Just have to figure out how to stiffen and support the fold … probably a combo of ply/foam held by standoffs. If I put the screen out 8” I can apparently get some effectiveness down to 125Hz … not sure how he’s calculating that … as he gives a theoretical number of 250Hz.
On the speaker blocking … I’d like to have some space between the screen and the front of the speaker … so no blocking behind. Just need enough space around it.

Might be a while as the plan was to have the screen, carpet, and seating, to get baseline measurements, before starting any treatment projects. The screen and projector are supposed to be here this month. The seats hopefully by August. The carpet I haven’t ordered yet. I might have to come up with an alternate plan as once the projector and screen are in … Im not gonna be able to wait! I’ll try and post an update to the HT thread soon.

Mojo, Kind of looking back and had some questions … Is that for max excursion? Heat dissipation? or something else … Was it measure at a frequency or broadband (noise or other)? Guess I want to know how you measured it … I.e. what does this wattage actually mean and if instantaneous power above that is useful. I’m assuming it is … It’s been a while since I’ve taken my electromagnetic courses … almost want to bone up on it again … but Can’t even remember how to do differential equations no less Maxwells anymore …

Ok…I’ll bite … you managed to separate the cone, voice coil, surround, and spider from the magnet and basket … btw that spider looks like you chewed it off with you teeth.
