Goldwood GW-208/4 8" OEM Woofer 4 Ohm
Goldwood GW-208/4 8" OEM Woofer 4 Ohm is rated 4.0833 out of 5 by 12.
Rated 4 out of 5 by from Great replacements for my old speakersI'm refurbishing an old pair of Bose 601's, and needed some 8 inch by 4 ohm speakers that closely matched the specs of the originals. And these fit the bill. If I were keeping these for myself, I may have gone with a more expensive selection, the next model up in the Goldwood line has rubber surrounds, which would last longer, but these are very nice speakers, and I was very impressed with the quality for the price, still superior to the woofers that came in these speakers. They should provide even better response and higher wattage rating than the originals too. I haven't heard them yet, but I have high expectations just from the quality of build and rated specs. So I can sell these refurbished speakers and they should make the new owners very happy.Note: they were a little large for the openings, just barely, 3/16 or so, that I had to increase the openings to accommodate these speakers.

Rated 5 out of 5 by from Perfect Replacement Speakers!!!Got these to replace the worn out woofers in my pair of 1976 Bolivar stereo speaker cabs & must say, they sound as good as the originals!! Very good price too. I couldn't be happier with this purchase.

Rated 4 out of 5 by from Surprising accuracyI was pleasantly surprised with the accuracy of the voice range. I'm using three of these in a very large center channel speaker and the dialog is clear and the drive projects across the large room, also.

Rated 5 out of 5 by from Great drop in replacement for an AR-4x woofer.I was looking for a pair of woofers to replace blown ones in a pair of AR-4x speakers. I ran the numbers on this one and found it to be a perfect match for the box. When I got the drivers I could see that they matched the originals so closely it seemed like they were designed for this speaker.Installation was smooth - mounting holes were in the same place as the originals, so it was a quick drop in replacement.I checked them by running them in an A - B check with another pair of AR-4x's with the original woofers - they sounded identical! At this price I was pleasantly surprised to find such a perfect replacement driver.

Goldwood GW-208/4 8" OEM Woofer 4 Ohm

90 dB @ 2.83W 1m or 90 dB @2.83V 1m?

1) 2.83V or 2.83W?2) Vas=0.81 cu ft and Qts=0.7. Will this do well (fair) in car without enclosure?
Asked by: RLee
I apologize for the typographical error, the correct specification is 90dB @ 2.83V/1m. The web copy has been corrected to reflect this. And yes, I'd say this speaker would be a good performer in a free-air mobile audio application.
