Seek info on Spectrum 208's components..

I bought these in 1985 and have always liked them. I took them apart today because I have spent way too much time on this site lately:)

The cabinets are chipboard, BR design, two way (kinda cheap, but nice walnut veneer). Internal dimensions are 13 1/16 W x 24 1/4 H x 8 7/16 D. 3" rear port about 4" long, lower half of cabinet. The woofer is mounted above the tweeter.


7 1/4 woofer, cloth dust cap, foam surrounds, paper cone. The only markings are: 117085 on the magnet and either B13-003 or 813-003 on the cone.

1 3/4 cone tweeter. No markings anywhere.

The crossover I just found out uses a metallized polyester capacitor, which I also just found out is not the best.

Not the highest quality speakers, I guess, but the drivers sound okay, and I was wondering if anyone could shed more light on them to help me decide what to do with them.

Here are some photos, the woofers first.

The crossover. Sorry about the focus.

The capacitor is an Eletrocube 4.0 +/- 20% 400V. And like I said, it metallized polyester.

The resistor has 2 (omega) 10% 5W printed on it.

It also has a 0.75A, 250v fuse connected from one end of the capacitor to the negative speaker terminal.

Thanks for any extra info or advice about what to do with this stuff.

The smaller brother to this model is the bookshelf 108a model. It got good reviews. same drive units. My friends and I had the 108's also. They sounded great with all kinds of music... the woofer was run direct, and the tweeter 12db/oct/ but very smooth. They were a really smart design for the money. They outperformed alot of other speakers i had.
