SS-H3600's - worth keeping? or throw out

[Madumi]

I'm trying to figure out if it's worth bi-amping some sony satellite ss h3600 speakers.

I'm figuring a TK2050 four-channel DIY might do for the amp @ about $150 total... Any thoughts on whether the speakers are worth it? I'm not in a position to buy different speakers, so it's just a use it, or throw it question.

Any input would be appreciated :-)

specs are as follows:

Satellite unit:
sens: 89 dB/W/
range 200-20,000 Hz
8 Ohms
50 W max input power

Bass unit:
sens: 89 db/W/
range 40-200 Hz
6 Ohms
70 W max input power

I tried looking up the drivers in the unit, but the Sony part numbers don't seem to help too much. Here's a copy of the only schematic I could find: link

The tweeter is a 2cm soft dome type, mid-range is an 8cm cone type, and the woofer is a 15cm cone type.

Any thoughts at all?
