Not aware of Snells needing an electric crossover. You need to check out the woofers because they go bad in these units if overdriven. There is also a Snell users group on the web. My thought is the speakers should sell for $800 in good condition.
Snell Type A II Speakers
I have a pair of Snell Type A II speakers. Does anyone have an idea of what they might be worth. They appear to be in pristine condition,but have been stored indoors at a friends house for the past ten years. I no longer have the electronic crossover unit they originally came with.I am considering moving to my home to test and then sell. Will they work without the electronic crossover? Any suggestions?
