would it be a huge mistake?

I own Genesis 500's and have had them for 5+ years, I would highly recommend them and other Genesis products despite the company's going out of business. They are great products. I guess if a driver goes bad, you'll have to do some research to get a replacement, but on this thread there's already a post by a dealer (Sound Ideas?) who has replacement parts. I have been eyeing all the 750's for sale cheap lately, and the 928 subwoofer, which is a great product too. If you can get Genesis speakers for cheap I would definitely buy them. The possible bad management of the company doesn't affect the great design and sound of the speakers. IMO.

If you like them and the price is right, buy them. If you've bought used equipment in the past, most do not come with a transferable warranty so it's the same situation. Also, just because you buy a product from a company in business today doesn't guarantee they'll be in business tomorrow.

Good luck,
Dave

Well, it would be a lot less complicated if the parts were off the shelf. Unfortunately, they aren't... and finding replacements will become more difficult as the years pass. Just look at all Apogee owners... not exactly easy to find parts when they go bad. Just keep in mind that if you buy a pair and cannot get parts, you are really out of luck. If you are buying a more expensive pair(200, 300 or 1.1), I would pick up a few spare drivers immediately while you know the parts are available.
