Im thinking I want to go back to point source loudspeakers to safe some space (college student). These were used in an open baffle line array and recieved on the order of 1-2 watts a piece at maximum.
I have the full specidications burried somewhere on my computer. But the published specifications were something like:
"Acoustic Research" brand
QTS: 0.7
FS: 40hz
Xmax: 6mm (a bit optimistic I think)
SPL: 85db
Outer diameter: 6 5/8
Z: 8 ohms
When I started using them I noticed the foam surrounds were very brittle. I added a bead of PVA glue around the surround so it wouldn't come off the frame, and two medium coats of "Modgepodge" on the cones and surrounds to protect them. I originally had 24 of them, but I was only able to save 20.
These have great extention down to about 50-60hz open baffle, with usable output down lower. I would reccomend crossoing them over with a tweeter array around 3khz or lower and highpassing them around 80hz with a dedicated substage if you want to approach live levels open baffle.
Asking $95 USD plus shipping OBO for all twenty. Using something like the ApexJr. tweeter at 50 cents each would yeild a very affortable line array. Pictures will be posted shortly.

Here are the full specifications, just found them:
Specifications: *Power handling: 50 watts RMS/75 watts max *VCdia: 1" *Le: .77 mH *Impedance: 8 ohms *Re: 7.5 ohms *Frequency range: 40-4,500 Hz *Fs: 40 Hz *SPL: 85 dB 1W/1m *Vas: 1.57 cu. ft. *Qms: 5.07 *Qes: 1.41 *Qts: 1.10 *Xmax: 6.5 mm *Dimensions: Overall diameter: 6-5/8", Cutout diameter: 5-1/2", Mounting depth: 3-7/8".
Still trying to get pictures to cooperate. Will get those soon! (sooner if I have interest
)

)Got some pictures off my phone finally. Keep in mind that there are only 20 available. The other four are still mounted on the line arrays in the pictures. I have since thrown them out and was going to condense the line arrays to 5.5-6 feet tall (And less wide) but I decided against it.
I paid 8 each, so for 20 thats US $160 plus the shipping. Taking a loss!
