Goldwood GW-8004 8" Coaxial Speaker
Goldwood GW-8004 8" Coaxial Speaker is rated 4.2222 out of 5 by 9.
Rated 5 out of 5 by from Great productUsed as replacement ceiling speakers in customer home and found bass enhanced greatly as well as cleaner, crisper highs.

Rated 3 out of 5 by from Cursury evaluation87 dB W/M is rather low. look at a Altec 409B. that low sens costs$ for power amplifier output. But then power amps are cheaper now, i guess. Still havn't figured out how they get 1000 watts from 12VDc in a amp with virtually no heatsink and 16 Ga wireing!!

Rated 4 out of 5 by from Keep it simpleI have just used a pair of these 1n some old dead antique RCA 100A speakers. I built them for rear channel cabinets in my vintage theater room. The sound just great in this application.

Goldwood GW-8004 8" Coaxial Speaker

I have a pair of the Dayton 8" ceiling speakers in a 1.6 cubic ft enclosure and the bass is poor. On a whim, I mounted some cheapo 5.25" pioneers and the bass was a little better...what? Now I'm looking into replacing the Daytons with these...thoughts?

I see there is hole on the back of the speaker.  Is it threaded for mounting a plate and a 70v transformer>

Asked by: Fastncool
The hole is simply a screw that holds the magnet to the basket assembly.

What would create better bass response for 2 of these in a space restricted box, a port or a passive radiator  

Asked by: mosbro18
The term "better" is relative. A sealed box will provide a smoother response, while a ported box will provide a bit of a natural bass boost. I usually recommend using a sealed box for these drivers, anything from 0.5-1 cubic foot will work well.

Seems like these would be good as open baffle drivers. Anybody tried that? Also seem like a good substitute for an expensive point source. Any thoughts or suggestions greatly appreciated. Looking at the 8" Visatrons also for open baffles.

Asked by: ibroke
These would work well in an OB application reaching into the low 50's pretty easily. I have not used them for this however, so I could not comment on the sound. They have been quite popular for our customers for numerous applications.

If I placed these in a cabinet with two other 15" woofers totalling 1000W RMS, how many of these should I put inside to match the output? for use outside for smaller parties and such.

im looking into buying a few of these for ht use and was wondering what box dimensions would you recomend using 3/4 inch mdf? or if these would be any good for ht use?

Asked by: ernj
These will work well for HT use. Assuming there will be a separate powered subwoofer, these will work well in anything from 1.0-2.4 cubic feet sealed.

This is an interesting driver for possible open baffel or sealed box line array like 8 per side. what would the low freq response be in say a 6 cuft s

in a 6 cubic ft sealed inclosure, 8 of theses drivers in a 6-cuft sealed inclosure , what kind of low freq response could youexpect to get .
Asked by: sammy malone
Eight of these in 6 cubic feet sealed provide an F3 of 63 Hz.

I need the QTC for my online calculator but that specification is never listed along with the other specifications , why is that ?

Asked by: sammy malone
The Qtc is not a speaker parameter, it is a box parameter. This is generally a number the program gives you based on the (sealed only) box volume and the speaker T/S parameters.

What is the center to center distance for an 8" Standard EIA 4 hole mounting configuration?

I have old antique pyramid shaped speaker enclosures with 4 studs on a 7-3/4" diameter bolt circle. Will these speakers fit over this pattern?
Asked by: Anonymous
Yes, the common spacing EIA standard for an 8" speaker is 7 3/4" o/c. This speaker should be a direct fit.

Ballpark for a notch filter?

By looking at published curve, can you guess at a notch to tame that bump?
Asked by: TicoLizard
A notch filter is used in association with the rise in the speakers impedence at resonant frequency. I don't understand use of one in an application with this speaker as a single speaker on a channel.Please provide more information. If this was to be used in a 2 way box with a 10" woofer I would most likely try an LCR at between 3.5khz and 4.5 khz.

Could I put 4 of these in a series-parallel to get 8ohms?

I was thinking of buying multiples of these and having 4 surrounds for each rear surround channel. Driven by 115 watts RMS per 4 drivers.
Asked by: eikm
Yes, you can wire 4 of these in a series-parallel configuration to achieve an 8 ohm load.

how would I build a vented box for this speaker to get the best overall response.

I/ve checked some speaker box calculators and find it hard to believe that I need a 3 foot tall box.
Asked by: jalang63
Please see the previous question and answer for the optimum vented box size.

where are the driver specs?

Neither your website or my package for these speakers have the woofer specs. How would one know how to design a proper vented cabinet without the driver specs?
Asked by: jalang63
The manufacturer lists the specifications as:Specifications: * Power handling: 35 watts RMS * VCdia: 1" * Le: .68 mH * Impedance: 8 ohms * Re: 7.6 ohms * Frequency range: 35-20,000 Hz * Fs: 51.1 Hz * SPL: 87 dB 1W/1m * Vas: 0.985 cu. ft. * Qms: 3.77 * Qes: 1.2 * Qts: 0.91.The optimum vented enclosure is quite large due to the Qts. I show that it would need to be 5.325 cubic feet and use two 3" diameter ports that are two inches long (I've listed a port below that you could cut to the correct length).This would create a cabinet that is tuned to 37 Hz, which is also close to what the F3 would be. I would list the power handling of this configuration at 20 watts RMS due to Xmax. Maximum output would be around 103 dB.
