These subwoofers worked perfectly as replacements in my old dbx subwoofer enclosure! I'm so happy that I didn't have to junk the entire rig just because my 20 year old subs wore out! I installed these two subs in my sealed subwoofer cabinet that sits on the floor. The box measures 1834; x 1234; x 834; and is packed with insulation. The subs fit perfectly in the holes and the terminals matched exactly. The bass from the subwoofer is great! Sounds like it did when I bought it. The price was very reasonable, too! I couldn't be happier with these subs.

Replaced the deteriorated speakers in my Klipsch Promedia 4.1. Sounds the same as the original to me, and saved me from buying a whole new speaker system for my computer!

I bought them to replace OEM Klipsch Promedia 2.1 woofer and they would bottom out at 25 volume with sub woofer level also at less than 25. I went ahead an ordered the Eminence Beta-6A that is a beast of a speaker. Magnet almost as big as the cone. Worked awesome.

GREAT replacement for JBL 2600 drivers. I can't rate the side by side to the original JBL woofers , but these sound great. It also looks like the 34;rubber34; surround on these will live much longer than the JBL 34;foam34; surrounds. JBL seems to use a very weak foam material , re-surrounding (repairing) the JBL with a after market rubber/foam ring to fix it might not have sounded so good. These speakers cost just a bit more that 34;repairing34; the originals, seem to work perfect in the JBL cabinet. Running them on a Dayton DTA 120 digital amp, they do just fine.

These sound really good.

What a great replacement speaker.I used it in a polk audio bookshelf speaker,and I cant tell a difference in the sound quality.wlWould definitely suggest.

awesome!! replaced a blown woofer in pair of bookshelf SONY 1970's speakers I got at the flea market for $10 bucks. pricey but worth it. sounds great!!

I used this to replace a driver in a Klipsch v2-400 Pro Media computer speaker system. It does bottom out a bit, but I am very pleased with it. Great value.

Very nice replacement drivers. My decades old EPI 70 woofers were shot; these had a great price, so tried them. Fit perfectly and deliver nice tight sound; with no boominess.

I used this woofers in self-made 3-way floor-standing tower cabinet. with 2 pcs. (powered parallel) in each speaker. For calculation I used WinISD and BassBox Pro 6.0 Enclosure internal volume - 1,2cu.ft; port length -6,8"; port diameter -2"; tuned at 38 HzThe result is very deep, powerful, elastic bass. Hard to believe that they are just 6-1/2", so there is no necessity to use additional subwoofer. Really the Best Bang for the Buck!
