Rated 5 out of 5 by from A GREAT DRIVER [FANTASTIC PRICE]I WAS REALLY SUPRISED AFTER I INSTALLED THESE DRIVERS IN NEW SPEAKER CABINETS THAT I BUILT FOR A FREIND, THEY SOUND BETTER THAN THE SAME SIZE PERLESS DRIVER I HAD USED 1-WEEK BEFORE. THESE ARE REALLY GOOD DRIVERS AND THERE VERY CHEAP...! ! ! I DIFFENTLY WILL USE THEM AGAIN.......... WOW ! ! ! ! !

Rated 5 out of 5 by from Good dealI had to replace a speaker in a Boston Acoustics Micro Media system subwoofer box. This speaker was an exact replacement. The only thing that I had to do to remount it was shave some material away from the mounting hole because the new speaker had a smaller mounting flange. No big deal. The speaker is like new for cheap.

Rated 5 out of 5 by from Perfect replacement driver.I blew a woofer in a Polk R10 bookshelf speaker, and needed a replacement driver. I bought a pair of Goldwood GW-205/4s5-1/4" woofers for the job. The cost from Parts Express was amere 25% of the factory quoted price for essentially the same driver! They sound great, and I'll be buying from Parts Express again in the near future.

Rated 3 out of 5 by from A good value, but not a great speakerI would not consider this driver for an application in which the driver would be visible. My two drivers were constructed rather sloppily, with exposed glue seams and foam gasket around the surround applied haphazardly (the holes in the surround were mismatched to the holes in the driver by about a half inch, and the other driver had the foam gasket material falling off the driver).The terminals for the connections are the usual male spade, but they are of very poor quality and its difficult to slide a female connector over them without the whole terminal bending and collapsing. Furthermore, they are mounted at an akward place on the basket which inevitably places the connections in interference with the mounting surface. Unless you bend the terminals inward, the connections will likely hit the mounting surface, knocking them off as you mount the driver. Frustrating.Performance is average, though considering the purchase price, these are still a very good value. None of the flaws mentioned prevented me from successfully installing the drivers, and once installed (in a 2 way ported cabinet) they sound acceptable. There is some breakup as they make their way towards the crossover frequency, and low bass sounds muddled (I wonder if they would be more at home in a sealed box after looking over the specifications).Overall, I'd buy these again if I was shopping at this price point, but if I could spend more I would buy something with better quality control.

Goldwood GW-205/4S 5-1/4" Shielded Poly Woofer 4 Ohm

I have a 1998 bmw 740il I need to replace the 4 speakers in the hi Fi subwoofer no sure which one to buy the 4 or 8 ohm?

Asked by: luimora1112
Unfortunately we do not have a cross reference for this type of thing. You will want to replace it with the same impedance as the original so you may need to research the stock speaker impedance to be sure. If the speaker still functions you could fine the DCR using a standard volt meter that measures resistance.
