    These woofers are great!

    Overall: 5 out of 5

    I have a pair of Electro Voice Sentry IV speakers that are nearly forty years old. The original woofers lasted 4 years. I have been using various woofers through the years as replacements and have never achieved the same quality of sound as the original EV woofers. Well I believe I have come as close as possible to the performance of the original EV's with these very inexpensive woofers. They are set up the same as the original Alnico EV's (two 4-ohm speakers in series). The tight, clean, clear bass reproduction is phenomenal. I am thoroughly satisfied with the price and performance of these woofers.

    These things thump as much as a gnat flying into a bass drum.

    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.

    Overall: 1 out of 5

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