Product Details

Goldwood GW-8028 8" Butyl Surround Woofer 8 Ohm

Butyl rubber surrounds are superior to foam in two important ways. First, the butyl rubber resists moisture and will not dry rot, providing years of service. Second, the rubber surround, due to its superior damping characteristics will greatly reduce cone break up and ensure low distortion. These woofers are ideal for replacing and upgrading old, worn out drivers. They all feature a polypropylene cone, vented pole piece, foam gasket, soft poly dust cap, and stamped steel frame.

Rated 4 out of 5 by from No complaints this timeThe sound of these speakers amazed me. I almost didn't have to use my powered sub base box because of the incredible sound range. I have them crossed over but I am not sure at what frequency because they were replacements. I'm breaking them in using a 40 Hz pure tone bass.

Rated 5 out of 5 by from great oem replacement and or upgradeinstalled these babys into a older toyota celica with the subs in front doors... these woofers fit without much modification and sound extremely better than the oem. system responds down past 40Hz with ease!

Rated 5 out of 5 by from Solid soundI purchased a pair of these to replace the woofers in a pair of KLH Model 32 speakers that were originally part of a system purchased in 1975, or thereabouts. One of the original woofers had weather damage and was distorting. These GW-8028s dropped right in, and matched the output of the original tweeters nicely. The low end is very crisp; not muddy in the least. I first compared several 8" woofers on specs and believed these Goldwood replacement would be the best match for the originals. My suspicions were spot on, as they sound absolutely amazing.

Are these magnetically shielded for use in a home theater system? More specifically, to repair a set of Sony SS-U4030 speakers?

Asked by: YellowEyedWolf
These are not shielded, but this should not be an issue unless you have an older style CRT "tube" TV.

will the goldwood  gw 8028 8" woofer be suitable for the bose 601 series 2 ?

Asked by: fatal1tywulf
The Goldwood is better suited in a sealed enclosure. It will work if you wanted to seal up the ports, but the Dayton below would be a nice solution if you did not want to stuff the ports. The cabinet cutouts might need to be modified for either option so you will want to double check dimensions.http://www.parts-express.com/dayton-audio-dc200-8-8-classic-woofer--295-310

I am ready to assemble my system but there is no Polarity marks on the GW 8028 woofer. Is there a way to figure it out? or does it not matter (which I don't think is the case).

Asked by: PauseButtonAudio
The terminals are marked but it can be hard to see. With the woofer facing up and the terminals facing you (as pictured), the positive terminal is on the left side.
