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.

Goldwood GW-8028 8" Butyl Surround Woofer 8 Ohm is rated 4.3968 out of 5 by 63.
Rated 5 out of 5 by from Great Bose 601 Woofer ReplacementTight fit in Bose 601 Series iii cabinets (these speakers were just a bit too large); however, install went fine without box modification. After listening to for several hours I still get that wonderful Bose 601 sound I have gotten used to. I and all my friends have always loved these speakers and with the replacements installed we think they are every bit as good as the originals.

Rated 4 out of 5 by from Excellent valueI ordered these for an install in a 1956 Chevy Belair. I wanted to use a band pass design that I used for many years with the original Kicker Competition drivers (circa 1991 or so) and I was looking for a specific sound for my father in laws car. I searched all over for drivers with similar specs to the old Kicker drivers and then landed on these. They worked perfectly. The entire system in the car sounds terrific and the bass has a smooth, even response that gets really low. I couldn't be happier with the sound and the fact that these drivers were cheap made them one of the best buys of the year!

Rated 5 out of 5 by from Just what I neededI used a pair of these speakers to replace the OEMs in a set of Radio Shack bookshelf ported 2-ways that were nearly 20 years old. The foam surrounds had completely failed. The replacements dropped neatly into place and the speakers sound as good as new.Had a heckuva time when the shipper lost the package for a week, but the folks at Parts Express did everything they could to help...even offering to ship a replacement set before the shipper finally 'found' the misdelivered shipment.

Rated 5 out of 5 by from Better Than OEM Drivers in CSW Model SixWhen the foam surrounds rotted away in my 15 year old Cambridge Soundworks Model Sixes I refoamed them only to find the driver was blown from not having the surround to hold the cone in place. Being a new pair is only about $200 I didn't want to spend a ton replacing the drivers... At under $50 for the pair these Goldwoods fit the bill and fit the enclosure. the screw holes didn't exactly line up so I rotated the speaker a bit and drilled new holes. The end result... They spound better than new! They match up nicely with the Model Six cone tweeter. The low end response is noticeably lower and more accurate than the OEM ones. Even my wife (who does not have a judgmental ear) noticed the difference. If you want to fix up a pair of Model Sixes or Advents or even upgrade their performance. You can't beat this driver.

Rated 5 out of 5 by from Blown pun intended......continued.../I had a old pair of Infinty RS3001's. I decided to replace the speakers simply because the cabinets were to nice to throw out. I chose these woofers after reading these reviews and because of the price. I am stunned at the quality. They are a great match for the Dayton tweeters I chose. I am sure I could have spent more money on another model and been happy as well but I went on the budget and was totally satisfied. I am a customer for life...My Infinity's live again

Rated 4 out of 5 by from Cost effective, great sounding wooferAs another reviewer stated below, I replaced the blown woofs in my Advent A1104's. Good bass response, and a perfect fit with no alterations. I use these everyday as part of my home theater setup, and I have been very happy with them. TV, movies and music all sound great! I would recommend these to anybody looking for a good replacement woofer for their classic Advents.

Rated 5 out of 5 by from Awesome value. Just break em in.These are awesome now they are broke in. My wife complained when I first installed them, but after a week she remarked that our system sounded so much better. I got these to upgrade a set of Sony speakers. Since the old ones were adequate but now worn out. The bass is so much accurate and deeper. Sound reproduction at low volume is greatly improved.

Rated 4 out of 5 by from Very good replacement wooferI needed replacement woofers because of a blown 8" in a 2 way ported PSB system. Parts Express tecnical assistance provided two reccommendations and explained what to expect from each. I purchased one which was received very quickly. The pair of speakers were easily installed. The only work reqired was to drill new mounting holes. The opening was correct.The sound is not the same as the original. I would describe it as more brilliant but with tighter more pronounced base. A different but good sound. I am very satisfied with the results and my first experience with Parts Express.

Rated 4 out of 5 by from Good value speakersReplaced the woofers from a pair of Bose speakers given by a co-worker. The woofers were in bad shape. I ordered these woofers and arrived in two days...a day early. I installed them in no time and the speakers were up and running...sounds good.

Rated 5 out of 5 by from Great speaker for the priceI purchased two of these woofers for an old pair of bookshelf speakers I have hung under the eves of my house outside above our hot tub. After 13 years outdoors the old paper woofers finally gave out. Although these are not rated for outside use I'm sure the poly cones will hold up at least as long if not longer than the old paper ones. Already the sound is much richer (more bass for sure) than the original due in large part to the larger magnets and butyl rubber surrounds. I am running these through Marantz MA500 125 watt amps and they sound great.I was also pleased find printed on their box that they are actually rated at 190 watts max (on the web page they are only rated at 90w).

Rated 4 out of 5 by from Served its purposeI needed two 8" woofers to replace the ones I had. The foam surrounds had dry rotted. I selected the Goldwood because it was cheap and I wasn't concerned with buying very high quality. Also it has a rubber surround that I am hoping will last a lot longer that foam. The sound quality is good enough for my usage in my college apartment. I can get the floors to rumble. I did have to drill new holes in the speaker box, but other than that, they are exactly what I was looking for.

Rated 4 out of 5 by from Replacement for broken spkr in audio testing boothUsed as a replacement speaker in a hearing testing booth attached to sophisticated audiometer. Worked great and calibrated well. Took 5 min to install and was less costly that the $150 (each) speaker the company wanted me to use.

Rated 5 out of 5 by from Good for Oldies but GoodiesI bought 2 woofers to replace the origional woofers in a pair of Realistic Electostat 2A's. Had repaired old Cones far too often, these drivers are a superb match sonically. Only caveat the 2A's mount from inside the cabinet so had to compress mounting gasket, and use a jig to mount using the origional Hardware without removing the grill cloth.

Rated 4 out of 5 by from Good ChoiceI used this woofer to replace a blown set in a Sony 3 way Speaker. They seem to handle much more power without distorting, than the original woofers. Very happy with this replacement speaker.

Rated 4 out of 5 by from Good sound for your dollar!I bought a pair of these to replace the blown 8" drivers in my JBL 3310 theater surrounds until I could get a better pair, but the sound I'm getting from them is nice enough that I can wait a bit. I wasn't expecting it, but the sound from them is close to what the originals were like. I couldn't be happier with my purchase!
