Not sure what the model number of these speakers is. I'll provide as much info as I can. The drivers all seem to work, but they are very old and most likely outdated by today's standards. The cabinets themselves are in pretty bad shape, I will strip them down and re-stain them with a ebony stain and re-varnish them. I am not sure what to use as a grill replacement, though, but I know I will want to use magnets to easily remove the front. I was thinking a white color to contrast the black cabinet, and I want something metal that is very transparent.
Prepare for information overload
The cabinets themselves are 19 11/16" tall, 11 7/16" wide, and 10 1/4" deep. Those are outside measurements, and the wood is 1/2" thick. There is also some padding around the sides in the interior, so by my estimations the internal airspace for the 8" driver (the other two drivers are of course sealed) would be best rounded to 1.2 cubic feet.
All the drivers are 8 ohms.
The 8" subwoofer has "I-502-223-II", "94-SDS" written on it and it is 4W.
The 4" midrange has "I-502-221-II", "93-SDS" written on it and is 2W.
The 2" tweeter has "222-11" written on it and is 10W.
The center of the subwoofer is 6" high from the bottom of the cabinet, and centered.
The center of the midrange is 7" above the subwoofer, and it is offset to the left of center by 2".
The center of the tweeter is 2 1/2" above the midrange and offset to the right of center by 1 1/2"
The port is 2 1/4" wide and 8" long.
The crossover is very, very basic. It consists of a 2uF cap filtering the 4" midrange and a 1uF cap filtering the tweeter. The subwoofer is not filtered at all, and thus runs fullrange.
Whew! Did you get all that
When I rebuild these cabinets, keep in mind that I don't want to spend a lot of money, but I do want to improve the sound quality as much as I can.
I was thinking this shopping list:
Crossover 3-Way 8 Ohm 800/5,000 Hz 100W 260-210
Dayton Audio DC200-8 8" Classic Woofer 295-310
JAMO 20470 4-1/2" Sealed Back Midrange 299-952 (I think it will fit, both drivers have the same diagonal measurement.)
JAMO 20132 2" Paper Cone Tweeter 299-965
I am a little worried about the tweeter fitting, the holes are the exact same distance apart but as you can see in the photos the old tweeter only has two mounting holes and the new tweeter has four, so the bottom hole of the new tweeter will hit the wood block that the port is mounted on. I'm not sure how to fix this, would it be possible to bend one corner of the tweeter up so it fits?
I would greatly appreciate any suggestions to my list.
