I am new to the forums (obviously), but in light of my recent acquisition will be spending quite a bit of time here. I recently was given a pair of altec Lansing speakers which I can identify only by the look of the speaker since I have yet to locate a model number on the speaker. It appears to be a 9872-8a, although the crossovers do not appear to be original. Both woofers are in good physical condition and sound ok. The horns are both non functional. One is missing the diaphragm and loading cap, the other is complete but ohms out as an open circuit. My amateur diagnosis is that with new diaphragms they should work. I have located aftermarkets for 33$ and OEMS for $110. The HF driver that was complete was labeled as an 806. The one that was not complete was missing the metal cap with binding posts.
So on to my questions:
1. Is it worth the extra to buy the OEMS for 3x the price?
2. Is there anything I should know before installing the new diaphragms? I'm assuming they are self centering.
3. Where would the model number typically be listed on these speakers so that I can verify what I have?
4. Can I install the loading cap and diaphragm to the driver that is missing the metal cap and just attach the wiring directly to the screw terminals on the loading cap, or is the metal cap with binding posts necessary for proper operation? ( I am having trouble locating a metal cap without buying the whole driver)
5. What kind of wattage should I use to drive these. I have a pair of brand new 1987 model rca dimensia amps which put out 100 watts per channel that I had planned to use with these. Will 100 watts be enough or will I need to bridge one amp per speaker?
6. Any extra help is appreciated. I am well versed in newer home equipment, but have never delved into pro audio equipment or for that matter any equipment that is this old.
Thanks in advance,
Justin
