Need specs on 8" speakers.

Searched but could not find specs. Looks like an Infinity speaker.

Need the specs on this 8" speaker.

Frequency response. Impedance. Max power

That did not take long. It will lead you to links for the rest of it. But, the typical speaker of that nature is w/in 3dB from about 500 hz to about 4 ,000 dB, and generally able to handle a 200 Watt amp that does not clip. Al l of the above depending on the crossover design, of course.

** From that data sheet we learn the woofer is a nominal 4 ohms type with a polypropylene ( see through) cone with response to around 3kHz followed by a smooth roll off. There is no LP filter in the x-over.

The 25-100W power rating quoted is for suitable amplifiers, at 4 ohms, so the magnet should be at least medium size with a 1.5 inch voice coil.

Seeing as most of the sound comes from this driver, one ought to replace both in a stereo pair.

I do not know how to translate what is on that spec sheet suggested to the woofer only specs. The posted freq response seems very short.

I see replacement 4 ohm speakers with better surround material and much higher frequency response but not sure if they are proper to use as a replacement for both woofers (two per enclosure) in the RS-4 speaker enclosures.

Back in the days I just bought speakers from Infinity but now these are not available.

This will be the third set going in and would probably be more replacements if I had not just used them with bad foam. Seemed OK as long as the volume was kept low.

Locally I can get a refoam but the material is questionable and more importantly I can get new supposedly compatible speakers for less than the cost of a refoam.

And the replacements use some poly-mica material or unspecified instead of the material used in the Infinity.

I doubt I can do a refoam myself at age 75.

Anyway, there are so many refoam kits out there that I have no idea which to use an what the material is. I want the speakers to last longer than me so my daughter can inherit a good set of speakers.
