These speakers were part of my favorite system. They were in a 1993 Saturn SL2 powered at first by a 2x25 head unit, then a 2x50 amp. They are so loud, that I literally couldn't stand it. They were used for about 1 year. Here are the specs:
Manufacturer: DEI Audio
Size: 6 1/2 inches
Magnet: 10 ounce
Power Handling 50 watts RMS/60 peak
Impedance 4 ohm
Freq. Response 70Hz - 20kHz
Efficiency 93 dB 1W/1M
Tweeter description 14mm mylar dome
Depth 2 1/2 inches
Again, I don't have the grills (sorry).
They sell for 109.95 each new. Take that into account when presenting an offer. I am willing to sell them in 2 sets of 2 or all 4 together. I don't care, just as long as I get rid of them and they go to someone who can appreciate them.
