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.

Thanks so much for your quick response. Answers to your questions

1) I am not technically limited to the drivers i have, but would like to keep this cheap (ill go big later when i know what im doin). Also, I already have a crossover (2 way, the original that was paired with the tweeter in the original old altec lansing speaker ) so if i go to a 3 way cabinet then i have to buy/build a new crossover....which id like to avoid.

2) Indeed, my goal is a first time functioning DIY speaker. Im not looking for Focal performance....just decent sound and a chance to learn some enclosure building for something other than a sub.

I found that the crossover is spec'ed at 2500hz. What do you think would be an appropriate box volume ported and sealed?
