OK at first I was a little worry received the wrong speaker made the call let know a mistake was made. No problem at all they maded correction didn't cost no extra shipping and handling.received correct speaker sounds great almost as good as the m&k speaker I finally bust after 25 years.

Bought a Vox Guitar 3W Practice Amp. The speaker in it sounded terrible. Swapped it out with this 5-1/4 in Mid Bass and it sounds awesome now. Thanks!

Boston Acoustic gave me the specs for my bookshelf speakers. ie 89 dB/watt/meter frequency response, etc. I measured the opening and this one is all but indistinguishable from the other. IN fact I am tempted to purchase a second because I am so well satisfied. Boston Acoustics and Polk Audio were terrific on the phone and it was a change from robophone!

Sounds Great
This replacement woofer sounds great. Bought it for my Onkyo book shelf speaker. the size was different from the original woofer, but a little router work solved that problem.Also way cheaper than buying new speakers. Thanks Simply Speakers.
