Product Details

Goldwood GW-6024 6-1/2" Butyl Surround Woofer 4 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-6024 6-1/2" Butyl Surround Woofer 4 Ohm
Goldwood GW-6024 6-1/2" Butyl Surround Woofer 4 Ohm is rated 4.0 out of 5 by 10.
Rated 5 out of 5 by from Breathed new life into our old JBL Control 5 MonitorsWe have 2 sets of old JBL Control 5's that have woofers with rotted out surrounds. We opted to replace them, but with a more economical woofer. These were the perfect choice. Correct impedance and power handling as well as a perfect fit. I even think that they made them sound a tad warmer( I think the 5's sound a bit bright to begin with). The bass appears to be better than with the original woofers. If I could have only done an A/B comparison. Seems to be a good replacement over the $55 original woofer. Plus they have a butyl rubber surround which will never break down like the foam ones do.

Rated 5 out of 5 by from Used as ReplacementsI have a pair of 20+ yrs old Polk Audio 5jr's and I blow one of the speakers. After doing some searching it was recommended that I use these as a replacement. I replaced the speaker in both boxes so they would be matched. I can't even tell the difference in sound quality. The specs on these seem better than the original Polk specs. Very happy with these.

Rated 4 out of 5 by from Good Low End Response!I tried this on a whim. Installed these 6024`s in a pair of 20 liter boxes. Used a passive c/o 12db AT 100 HZ. Box response software shows a QTC of .90, F3 of 57.6 hz., and a F7 of 45 hz, all from sealed cabinets. Oh yes, had .5 RE resistance factored in. The 45 hz. at F7 is very beleivable as the low end of these woofers is very forceful. I would use these again with the caveat of needing a somewhat larger box which will keep the QTC from getting out of hand. At .90 it is getting a mite thumpy, yet still ok. The woofers WT3 measured out at +/- 5 to 10% from one another. This could have been better, hence the lowered rating.

Rated 5 out of 5 by from WT3 test confirms these are good Polk replacementsThe previous reviewer must have received defective woofers. WT3 woofer analysis shows that the Goldwood 6024 woofer impedance curves to be better than the 6502 Polk woofers. The plots show that these Goldwood woofers have better mid-band/bass response which can be heard. This based on the impedance staying low through out this part of the band. The Polk 5, 5A's lack in the low bass/midrange department and this is were the Goldwoods shine. WT3 is a excellent tool for woofer analysis. I also conducted a blind test using 4 different people on Polk 6502's installed in Polk 5A's verses the Goldwood 6024's and the results again prove that this Goldwood woofer has better midrange response and tighter bass with better punch.So with all this data I am unclear as to why the previous review had issues unless he received defective woofers. If you want the original flat sounding Polks then buy 6502/6500's, but for alot less money these Goldwoods work great.

Rated 2 out of 5 by from Look for something better.As another reviewer did, I purchased a pair of these to replace the woofers in a pair of Polk speakers. I was disappointed with the sound quality - these are certainly no replacement for Polk's 6502 woofer. Worse Goldwood seems to have quality control issues. The two woofers I received sound significantly different and have significantly different sensitivities (at least 6 db).

Rated 5 out of 5 by from Great Polk Monitor Replacement***Very Suprising*I have purchased 4 sets of these 6.5"s. In 4 and 8 ohms. They perform excellent. Much better than was expected. The dimensions are perfect for the old Polk Monitor Series. I have replaced some noisey Polk 6.5's with these and was astounded. After break in these thing really came alive. The mids picked up and the lows were more punchy and controlled. These things have a decent Vmax and a large voice coil and 90db 1m/1w. Decent build quality. Try a pair in your old Polk Monitor 5jr's, 5's, 7's and see for yourself. I'am truly amazed how these things perform. Best keep secret. Don't want the price going up!!!

Goldwood GW-6024 6-1/2" Butyl Surround Woofer 4 Ohm

How are these for replacement of late 90's Town Car subwoofer? Do they fit? Do they have enough excursion?

Do the electrical characteristics match closely enough?
Asked by: Joanne
Unfortunately, we do not have a cross-reference as to which of our products will (or will not) fit into this vehicle or that. For subwoofer replacements, I would recommend going with an actual subwoofer, rather than a woofer, which is what this product is. Aside from that, you want to match the physical dimensions and impedance.
