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.

Goldwood GW-8028 8" Butyl Surround Woofer 8 Ohm

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.

These speakers seem to match perfectly with the replacement speakers for EVENT 20/30's. My main concern is will i be able to put the shielding from the old speaker onto these speakers. These speakers look identical right down to the piston diameters etc. 

Asked by: AB TEX
In order to properly shield a speaker you have to use a bucking magnet that is glued to the existing magnet, in the direction that they are forcing themselves apart. You will only need a shielded driver if the speakers are very close to an older CRT type television or monitor, they do not effect a flat screen TV.

What is the optimum internal volume of a cabinet for two of these?

I am intending to build two cabinets with two woofers in each. They are to be used as my surround speakers, and modeled after my Infinity Column II's I bought back in the '70's. They have tens in them and are about a foot square and 40 inches tall. I would like the finished product to be roughly 80% of the Infinity's.
Asked by: Speakerasm
The recommended enclosure for these is about 6 cubic feet sealed. They will work in a smaller volume that is heavily stuffed however. You can expect in room response into the mid-upper 30's.
