Nightshade v.3 Information
BobbyG2 replied to sundownz's topic in Sundown Audio - GREAT Amps/Subs! GREAT Customer Service!
The QTS with stock coil and aluminum pole sleeve is fairly high ; would have to check it exactly when built. I can also expand the OD a bit to raise QTS further as there are 3 options wider on the OD than stock with the sleeve system So yes, we can do pretty much anything with the motor and sleeve system. Awesome man, thank you. I know what my next substage upgrade will be than. -

Think that with all these options an 18" sub ideal for infinite baffle could be built? (qts ~.6, fs < 30hz) -

SA8 Free air

Yeah, that's infinite baffle. Neither the SA 8 or SD2 8 will work well in infinite baffle. Here's a good quote I found that describes what you need to look for when choosing a driver for IB better than I can: The SA 8 has way too low an Qts (.33), and a little too high an Fs (35hz). The SD2-8 has an acceptable Qts(.58), but way too high an Fs(45.2hz). You're going to want to find an 8 with an Qts of >.6, an Fs ~30-35hz, and a decent amount of excursion. With infinite baffle, I highly recommend getting drivers with more cone area! a Single 8" is not going to be very loud at all. But if you must, than the Dayton RS HF 8" is what I'd recommend. A little low on the Qts(.5) side but with an Fs of 28Hz you shouldn't notice that. Be careful, though, it doesn't have all that much excursion(9mm), and cone area and excursion are the things you need for output in infinite baffle! http://www.parts-express.com/pe/showdetl.cfm?partnumber=295-456 -
