Goldwood GW-8PC-4 8" Heavy Duty Woofer 4 Ohm
Goldwood GW-8PC-4 8" Heavy Duty Woofer 4 Ohm is rated 4.5 out of 5 by 22.
Rated 5 out of 5 by from Best so farVery articulate, clean mid-bass that slams to my satisfaction. I use it as my woofer in a 3-way tri-amp system powered by a A500 amp. I tried the Dayton Designer series and they were overpowered with this setup and choked. My system is 2 Canton tweeters, 2 ge8pc-4 and 2 18" classes subs powered with Rocksan 80/ch, A500 200/ch, and crown xls1500 525/ch using MiniDSP for crossovers. This setup sounds awesome. Thanks PE!

Rated 5 out of 5 by from Great replacement woofer for my Allison CD7sRather than repair my 30-year old cone rubber, I decided to replace the entire speaker. As I had the original Allison spec documents, these Goldwood speakers line up almost perfectly technically. More importantly, they sound great. I'm so pleased finding the speakers.PS - I purchased replacement 12-inch woofers for my Allison CD9s a couple years ago from Parts-Express. I recommend them.

Rated 5 out of 5 by from Very low distortion! Very high power handling.The woofer is very low distortion as far as I can tell. The speaker terminals are very nice. The magnet is rather large as well. Very clean sound. No punchy bass but is good enough. Doesn't have enough excursion (3.5mm) to make a whole lot of bass. Guess thats what a sub is for. It doesn't go to 7k hertz or whatever it is. Only about 2.5khz which is good enough to cross with a tweeter. The power handling is very nice as well! Probably more than just about any other one minus the pro speakers. I also love that it is 4 ohms as it produces a bit more volume and is compatible with car amps.

Rated 5 out of 5 by from Fit the Bill NicelyPurchased these to replace worn out Prodigy tower speakers. They sound better than the originals and seem to be a perfect match for the crossover in the towers. I had called PE because I initially could not find an 8 inch speaker in 4 ohm with the power requirement I had. I am running these in part of a 7.1 surround sound powered by a Denon AVR-790 system. All I can say is they ROCK! PE got back to me quickly and I had these speakers in TWO Days, no special shipping. Love these speakers and PE! Thanks!!!!!

Rated 5 out of 5 by from Great valueSound every bit as good or better than the Jamo drivers I replaced.

Rated 5 out of 5 by from Nice in active setup.Used them crossed over at 3 khz 12db/oct. LR. Very responsive, accurate and no audible distortion at 2/3 their power rating..Music tells them to do something and my ears and Holm Impulse seem to think that they are doing it right.They have good looks and the cast frame is nice.

Goldwood GW-8PC-4 8" Heavy Duty Woofer 4 Ohm

I require the outside diameter to be exactly 8 inch's. Is the "Goldwood GW-8PC-4 8" Heavy Duty Woofer 4 Ohm" exactly 8 inch's outside diameter? Fitting Boston Acoustics T1030 woofers.

Asked by: Danny T
Yes these have a diameter of exactly 8".

Is this driver optimized for sealed or ported. I'm about to build a enclosure for them and am going back and forth sealed of ported. I would build it to your recommendations and tune it to 44hz. I have a minidsp so I can send them any signal at any slope.

Asked by: Shoe
This will work well in either type but you will get more useful bottom end in a ported enclosure.

Expected performance from 2 of these connected in series for a 8 ohm load in a MTM 42" tall tower with 275-070 tweeter and 260-142 crossover? The tower will be divided at about 34" so the woofers can get their own 2 ft3 compartment with 2"x2" round port.

Asked by: Big_Louis_1971
Unfortunately we cannot say how the speaker as a whole will sound, but the box and port configuration looks good for a pair of those. You will have an F3 of 44 Hz and a tuning frequency of 33 Hz.

I'm looking to replace the warn out woofer in my Allison CD7 speakers. After 30 years the 8" rubber cone is cracked. I believe specs are 4 ohm. What are suitable replacements? I'm looking at GW-8PC-30-4. What's your advice?

Asked by: BBRandy
This might be a good option. The main thing to check would be the actual driver dimensions. There is some variation on speaker frames so the outside diameter and cutout is important

Woofer Selection & Performance

Hi, i am looking for some guidance here before making the purchase. I am replacing a woofer driver for a studio set-up wich i use for DJing. The unit is a yamaha HS10w. The sub is rated at 150w Dynamic power (so about 75rms) @ 4ohms. Overall frequency is 30Hz-180Hz (-10db).I wanted to use the Goldwood GW-8PC-4 8" as it appears to have more balls and could probably handle the deep-mid baselines without getting flooged out as the OEM driver struggled.Is that a good selction for the unit? Will the amp be able to power the speaker given that it is rated at a lesseer RMS that the speaker itself.
Asked by: Bruza005
This driver would probably work OK for the application although you may want to look into the Dayton Classic 8" subwoofer which is ideal for the enclosure you have and has more excursion capabilities for higher output potiential.

I am considering putting two of these in one box,I intend to double the volume of one for volume.I"m having trouble determing port size. Any help woul

Asked by: saw buck
In theory, if a single driver calls for a specific box size and port then two drivers would be doubled with 2 ports to make a bass reflex or vented speaker.But first understand what the difference is between sealed and ported is. A sealed box presents the speakers frequency as It's design dictates. The sound is tight in characteristic, meaning a solid transient responce. A kick drum will have a good thud as well as low pitch. An explosions will have some felt concussion because it is tight air movement.A reflex or vented box, depending on the port tuning will enhance a narrow band of low frequencies making them louder and appear sonically stronger at the expense of some loss in tightness. There is some subjectivity over preferences here. In audio reproduction each has their place. In my band, subs are ported bass reflex double 18", but my home system is sealed 12" and very tight.You have a unique opportunity to design what you want. I would consider the two subs with an internal baffle divider and only one tuned port. This couldgive you both characteristics to some degree and if desired a second port could be added later.A port can also cause a subtle air velocity noise but I have never found it to be a big problem. Dont be afraid to experiment and have fun.
