    I've used three sizes of the 8 ohm versions in this series and love them all. Build quality is great, sound is at least as good as the original, and price is ridiculously low. For rebuilding, repairing old equipment for resale, these cannot be beat. I even resell these as replacements in my shop, my customers love them. There is no better value out there.

    I ordered a woofer before this one and was damaged too. I think i'll never buy from you again.
