I have all the plans if you want them!
Yeah, I couldnt figure out what the midbass horn design was accomplishing other then a massive headache for me, I scrapped it in the first 4 hours of cutting when I screwed up two angled piece and then chucked a piece of wood at the wall for no reason then to clear my head
Dual JBL 2226s gave me 100dB sensitivity already.
Well, that isn't very encouraging news! Is this the same design that John Sheerin posted on DIYaudio? I should probably just go sealed as originally planned anyway; perfect match for the 4 2-driver IB manifolds.
Funny reading the excuses about lack of progress on the HT projects. I can whole-heartedly identify!
My biggest excuse for lack of progress is I really wish my room was larger than the 12x24 that it is. But everytime I ponder the possibility of an addition or consider selling the house and rebuilding, the reality is the cost-to-benefit ratio is really ****** for the added square feet.
As for the amp debate, I'm sure cheap low power amplification would provide quite a few dB and sound just fine doing it in Scott's system. Not what he would probably want for a long-term solution, but how much power is really 'needed'? Totally subjective, but obviously DIY guys tend to lean towards the overkill side of things.
Over a period of years I've aquired 8 QSC DCA-series amps -- (5) 1622, (1) 2422, (1) 3022, and a 1644 -- for power in my theater, but why in the hell do I 'need' to have 15k watts on tap to power compression drivers, hugely efficient 15" midbass, and 15"/18" IB drivers in a 300 square foot room? Kinda boggles the mind.
So in a concession to practicality, there are 2 Emotiva LPA-1's slated to do the job instead. Hopefully the noise floor issues Doug had won't be as bad in my room...this option seems much more sensible than a huge cool looking rack full of 8 highly respected QSC pro amps with unlimited power reserves on tap...(er, um, wait a second here...)
