Goldwood GW-S650/8 6-1/2" Poly Cone Woofer 8 Ohm
Goldwood GW-S650/8 6-1/2" Poly Cone Woofer 8 Ohm is rated 4.2083 out of 5 by 24.
Rated 5 out of 5 by from The right driverI am building a new center channel based on the Goldwood GT510 tweeter to match front left and right speakers which have that same tweeter. I am using this woofer in an MTM configuration along with an MTM crossover I got on ebay. In the MTM configuration, this woofers sensitivity matches the GT510. I only have the center channel speaker in a home made break out box for now just to see if my design is good. Well, it is. My front channels now blend perfectly. Really good price, too.Does anyone know what 6 1/2" or 5 1/4" driver would match this tweeters sensitivity in a single driver setup? I would like to try that for rear channels

Rated 4 out of 5 by from Good WooferI bought this along with a Dayton crossover and Tang Band tweeter to replace thecomponents in a 40 year old BSR bookshelf speaker. OK, so it would not take muchto improve on that. This speaker fit the old mounting exactly, so I was pleased aboutthat. And using the crossover in place of a filter cap, made the whole speaker equalto a modest studio monitor. I compared it to a small Klipsh bookshelf I have and ithas much better high end. I have not had a chance to compare it to some JBL 305sI have, but it seems pretty good at this point. I have it crossed over at 1.9k whichcould be higher, but it seems fine as is.

Rated 5 out of 5 by from Awesome upgrade to OEMplaced these in the rear doors of '01 Suburban. They are not an exact fit as the magnets are much bigger but I got them in there. The sound is superior to anything I listened to, up to 4 times the price and they were the correct impedance ( 8 ohm ) which is impossible to find except at PartsExpress. Front speakers, subwoofer and tweeters were purchased as well and will be reviewed upon installation. Presently only the rear doors are connected and it sounds good enough to leave as is.

Rated 2 out of 5 by from Can't Take The PowerEven when used with a good quality crossover, could not take the power & blew immediately...before they went out, they did sound good, but had low volume compared to other speakers in the system. Power ratings are actually much lower... I had them crossed over with a 120Hz high pass 6db, purchased a different manufacturer's speakers and they have been in use for 5 years now without a problem.

Rated 4 out of 5 by from Excellent bang-for-the-buck woofer replacementI bought these to replace the blown stock woofers on a hard-to-find pair of Sansui S-M90's. They were a literal drop-in for the speaker, and they sound great for the price. The quality of the bass produced was unexpected at this price. My only complaint is that I noticed they were priced cheaper in their magazine then online.

Rated 5 out of 5 by from Great sound, great priceMy old Sony's woofer cones were falling apart. I was looking for a replacement and this fit the bill. It sounds excellent for such a affordable price.
