Goldwood GW-15PC-4 15" Heavy Duty Woofer 4 Ohm
Goldwood GW-15PC-4 15" Heavy Duty Woofer 4 Ohm is rated 4.5 out of 5 by 12.
Rated 5 out of 5 by from Sounds greatReplaced a fried woofer in a classic old Shure 709...really sounds nice!

Rated 5 out of 5 by from Great build quality for the moneyThis really is a Heavy Duty woofer for its price range. These woofers have the efficiency and ideal rising low end response to be used in a dipole system. Using two of these woofers in a "W" frame dipole arrangement with some EQ boost on the bottom octave will make for a truly capable open baffle sub woofer!

Rated 5 out of 5 by from Replacement Woofer for Infinity SM152This speaker was used as a replacement for the Woofer in my Infinity SM152 speakers. The bass was as good if not better than the original and the fit was perfect. A great replacement for the money!

Rated 5 out of 5 by from Awesome ValueI purchased 2 of the Goldwood GW-15PC-75-4 15" Heavy Duty Woofer 4 Ohm speakers for replacement in some very old Traynor floor wedge monitors. I wanted to use them to supliment a set of new Yamaha stage monitors. I went low cost because I only needed some fill in sound so I decided to rebuild the cabinets I already had.After install, I tested them with a small amp to make sure thery played but didn't set up the regular PA system. That weekend, I set the Traynor rebuilds up and W O W! The low end was smooth and clear volume was right in line with what I needed to achieve except the mids & highs were a little less only because the horn drivers were old. I late replaced them with sillenium drivers and now the Traynors are my go to monitor and the Yamahas are my suplimental.A great speaker for any price and definately for under the 100 buck price.

Rated 5 out of 5 by from AwesomePaper speakers suck, but this speaker is better than most expensive woofers. Once you break in the speaker it manages to hit all the lows and no distortion.

Goldwood GW-15PC-4 15" Heavy Duty Woofer 4 Ohm

I'm finally putting this driver into a 4.5 cu. ft. cabinet. I want it ported to play low, not forced - just a good, sensible bottom end. In otherwords, best fidelity. Thank you for all your help.

Asked by: denzee300
In that volume I would recommend a 4" diameter dual flared port that is 6" long. This will provide a tuning frequency of 29 Hz.

Where do you suppose i could find an accurate response curve? I don't have the ability to test these. Thank you.

Asked by: denzee300
Goldwood provides a sample response curve on the product page which can be viewed in the PDF below.www.parts-express.com/pedocs/more-info/290-336-goldwood-gw-15pc-75-4-more-info.pdf
