Wardsweb, Where to get more info on the Studio One Pi towers?
Quote from: wendell on 27 Aug 2006, 06:01 amWardsweb, Where to get more info on the Studio One Pi towers? I built the Studio One Pi towers using Pi Speakers' stock Studio One kit ($150/pr) in a tower enclosure I designed using WinISD. The objective was to build a nice looking, high WAF, high sensitivity, and very affordable speaker in a tower enclosure that coaxes good bass from the Eminence Alpha 8 without the loss of sensitivity that would result from baffle step compensation. The stock One Pi standmount enlosure's smaller volume limits the bass extension a bit, and I've found it's just as easy and cheap to build a floorstander when you're DIY'ing it. The result is about 95dB sensitivity and bass extension into the 40's for a total cost of about $250/pr, a good speaker solution for anybody having a SET amp in the 2 to 8 watt range who can't quite afford any of the high sensitivity speakers that are commercially available. The latest version I built is 36" high, 9.5" wide, 13.25" deep, with a 4" by 4" port.
You may need to add a swamping resistor to flatten it out some.
Hey Josh,Watch the impedance spike at the JBL's Fs. You may need to add a swamping resistor to flatten it out some. Are you planning on a PP or SET amp? If it's a PP, a little negative feedback will also help boost the amps damping factor just a smidge.
