Product Details

Goldwood GW-8024 8" 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-8024 8" Butyl Surround Woofer 4 Ohm is rated 4.303 out of 5 by 33.
Rated 4 out of 5 by from Economical replacementI bought this as a replacement for my son's 2002 Avalon. OEM replacement was very expensive. This speaker is a good replacement. Though not as much base as the original, it definitely makes a difference in the sound of the system. Great alternative, especially for the price!

Rated 4 out of 5 by from Good substitute woofer for original JBL in my 2003Installed in my 2003 Toyota Avalon to replace original JBL woofer. Job took several hours to install but the bass is now operational and sounds good.

Rated 4 out of 5 by from Good sound.This isn't a exact fit for replacement of the woofer in the back of your suburban. You'll need to get a mounting kit. also the speaker is too long/ depth wise to fit snug w/o it. other than that the sound is awesome. really didn't know how much I was missing until I replaced it. one other thing , the electrical connector from YOUR hardware (speaker wires have two sizes. Sm & Lg. this speaker has males ends that are standard size. so your Lg female is going to be loose connection. easy fix if you've done wiring before w/ speakers.

Rated 5 out of 5 by from Replacement Woofer in my 2002 Toyota AvalonThe site was easy to navigate and I found the recommended replacement speaker easily. I sent a request to confirm this unit as a legitimate replacement and got a quick response. The shipment went out right away along with a confirmation email. I received the speaker and installing it was a breeze. The original speaker was 3.7 ohms and the replacement was 4 ohms and I can not tell the difference. It sounds great and I am very happy.

So i serched for an inexpensive replacement and found the Goldwood 4 ohms repalcement. Oerdering / shipping/ and install was so quick and easy.. The important part is theysound better then the original factory woofer. I'll be replacing the other one thisweek.

Rated 4 out of 5 by from Good replacement sub for a ToyotaLike many Toyota Avalon owners, my woofer eventually died because of mechanical deterioration of the foam surround. I lived with it for a while by cutting the wire to the speaker to eliminate the annoying distortion, but the JBL system was severely lacking in bass without the woofer. BTW, I have a 2004 Avalon, and my parents have a 2002 Avalon, and we both had our woofers fail in the same manner, so this seems like a common problem.I goggled for a replacement, and found some people were using this woofer, so I took the plunge. Some people also have their old speakers repaired, but I opted not to do that. Parts Express had the speaker to me 3 days after ordering, which was great for standard shipping.Installation was fairly easy, but I can only speak for the 2004 Avalon XLS. I think older Toyota Avalons might need more work, such as rear seat removal from what I read on the internet, but here are the steps I took, no rear seat removal needed.1) Removed the rear 3rd brake light cover by pulling firmly on it, straight back away from the rear window. Don't pull up on it, just level to the rear deck.2) Removed the four 10mm bolts holding the plastic mounting plate. Use a mirror to see them if needed. A socket and ratchet fits no problem.3) Some slight trimming of the rear deck was needed for me, using a box cutter. You can see the impression of the 3rd brake light assembly on the felt of the rear deck, I cut to about half an inch of the impression. The material removed is under the brake light when it's put back on, so the cuts won't bee seen.4) The brake light can just be moved to the side, there was no need to unplug it for me. You will also see a plug for the speaker that needs to be disconnected: this has a locking tab on the side that must be depressed. (do this after you get the speaker mounting plate out)5) Now, with some wiggling and turning, the speaker mount plate can be removed, but it's still a tight squeeze even with the rear deck trimmed.6) NOTE: for my speaker polarity was not as expected: there is a black and red wire to the old speaker, and one would assume black is negative. This was not the case for me. I connected a 9V battery (using alligator clip jumper wires) to the old speaker, which is not polarity marked, and noted the direction the cone moved with negative to the black, positive to where the red wire went. To my surprise, connecting the battery negative to negative on the new woofer resulted in the cone moving in the OPPOSITE direction. Due to this, when I wired the new speaker, I put red to the negative terminal, and black on positive. Possibly my original sub was wired wrong, but I wanted the cone direction to match the old, since it never sounded bad when it worked.7) I then removed the four Phillips screws on the bottom of the plastic plate (which had been hidden when the plate was installed in the deck) and removed the top ring (which has the mesh) and removed the old speaker. It was all stuck together pretty good, but some elbow grease got it apart.8) This new speaker can not be mounted in the exact same way as the old, as it has no tabs. After some experimenting on the workbench, I decided to sandwich it between the bottom plate and the top ring, being careful not to make the screws super tight, since the plastic tabs they go through will have a gap between the plate and ring. I suppose one could peel the foam off of the top of the new speaker, but I didn't bother, as I thought this would provide a bit of a seal, and prevent vibration. How you mount the speaker is your preference, but this seemed easiest to me, no drilling, etc, and the speaker would not stick too far into the trunk. In short, I used a "top mount", with the mesh ring holding it all together.9) I then soldered the wires to the new speaker terminals (the wires are short, so make sure you have rotated the speaker correctly), with the black wire going to positive, as discussed above. As a note, I did try the wires both ways as a test, and did not notice a difference, but I wanted the cone to move in the same direction as the old speaker when the same polarity was applied. Maybe the old speaker is designed to be reversed polarity, or maybe it doesn't matter since there were no polarity markings on it, who knows for sure.10) Reinstall, basically the reversed of the steps above.OK, now my observations on how the speaker sounds after using if for a few days. This new speaker is 4 ohms, vs 2 for the original, so the bass is not as loud, but it is still very good. The original speaker magnet seems a bit larger as well. But the original also seems to have a cheaper cone (paper, it appears) and the infamous foam surround that fails.I turned my bass control up a few clicks than what I used to have, and faded a few clicks to the rear, which dialed it in nicely. If you are a bass fiend, you might want to get your old speaker repaired, of find another, but for me there is enough bass. Maybe not having the woofer for so long made me appreciate it. The bass is very clean, and not boomy. Zero distortion heard, even at maximum volume. I listen mostly to classic rock, so those who like super deep bass for rap and such might not be satisfied. For me, this was a great fix to an annoying problem. Seriously, if you are an audiophile who wants super bass, you would probably replace the entire system anyway, as this audio system is old and does not even have USB, etc. But for me, this replacement speaker got the sound back to near-original, in a very economical solution.I hope you found this review helpful.

Trying to replace the subwoofer in my 2000 Yukon, which has 2 ohm rating. I am assuming I can parallel the wiring to make it 2 ohm. Will this speaker work ?

Asked by: beachstock
If the original woofer was a dual voice coil model, meaning it had two positive (+) and two negative (-) connections, you cannot tie those wires together. You can however use a single coil sub like this Goldwood and it will work, you will just get slightly less power from the amp due to the 4 ohm rating.

would these be a good replacement for a vintage pair of MTX aal 83  3 way home speakers? my woofers finally wore out after 20 years!!!!

Asked by: sansuidave1
This would work okay although a better option for that cabinet would be the Dayton Classic 8" which you can see below. This requires a cutout of 7.2" so slight cabinet modifications may be required for it to fit properly.
