Novice Speaker Builder....HELP!

Postby tgauger » Wed Oct 03, 2012 2:43 am

Dear Wise ones,

I am a car audio guy who is dipping his toes into home audio speaker building. I have built many subwoofer enclosures in the past and have a decent grasp of home audio. I've also worked in radio broadcast so i am very familiar with what a good speaker sounds like, so your efforts will not be in vain.

Basically the deal is this. I have a set of drivers and tweeters (new stuff) that a friend gave me. I would like to build a nice set of tower speakers for my living room. I do not have specs on the tweets but they are 1" silk domes. The drivers are (cheap) GRS 8PR-8" speakers with the TS parameters are as follows.

Specifications: • Power handling: 65 watts RMS/90 watts max • VCdia: 1-1/2" • Le: 1.07 mH • Impedance: 8 ohms • Re: 7.58 ohms • Frequency range: 40-5,000 Hz • Fs: 52 Hz • SPL: 85 dB 1W/1m • Vas: 0.76 cu. ft. • Qms: 4.77 • Qes: 1.45 • Qts: 1.11 • Xmax: 3 mm • Dimensions: Overall diameter: 8", Cutout diameter: 7-5/16", Depth: 3-7/16".

Ideally i would like to build some 5ish foot tall towers. Ported would be preferred, just because im gonna have to try to maximize the bass response from a driver with only a 3mm xmax but Id be fine with sealed. Folks, any help would be appreciated. If you guys could give me some sample boxes that would be awesome.

Thanks so much.
