Goldwood GW-215/40/8 15" OEM Woofer 40 oz.
Hi, I want to build either a vented or sealed box for this speaker. I tried using it as an open-baffle and just cannot fill out the sound that way. I do not have room for a fully vented box. What would I get at 27cu/ft vented and sealed?
That volume is quite a bit larger than the sealed recommendation and quite a bit smaller than the vented. This woofer is not a great candidate for a vented design. I would recommend keeping it sealed, you could get away with four of these in that volume and have good results. With one your F3 is 28 Hz, but your power handling is very low. In that volume the woofer will reach Xmax with only 15 watts of power.

Could I use this speaker for a replacement woofer on a vintage Peavey TKO 75 guitar amp?

With a QTS at 1.09 would this be recommended for an open-baffle mono subwoofer? I made a pair of open-baffle 2-Way speakers and think this might marry up well mounted on a 2 x 4 foot floor panel........
A quick search of the internet finds that this is a common use for this and similar high-Qts drivers. I think this woofer should work well in your application.

I see reports of woofers crossed as low as 125Hz so if this one is rated at 20Hz to 2.5kHz what governs the crossover point? I'm using a Selenium D250x as a midrange with appropriate horn.The woofer is in an H frame a la Martin Kings work.Appreciate help
The crossover point is governed by passive crossover components, which at 125 Hz would be quite large, or an electronic crossover if used in a multi amp system.

MMS wrong? Diaphragm Mass Inc. Airload (Mms) 0.07g
Seems to low for a 15" woofer.less that 1gram of air??
This is a typo on Goldwoods spec sheet that was mistakenly transferred to our website. Actual measured Mms is 110 g.

use in 2 way pa speakers?
Could I replce old drivers in a 2 way pa system with thease woofers? There are no crossovers in the speakers either.thanks
Well, you kinda got me on this one. I have to believe there is some sort of crossover, no matter how simple, inside the speaker. Is the tweeter a piezo? (no magnet structure on the back) If so that may explain it. Anyway, yes, you could, but it would need to be a decent size box, preferably a ported one. Plus, this speaker is "rated" up to 2,500hz, which is about were 2 way PA cabs would be crossed over anyways. Just don't hook it up to a very high powered amp unless it has limiters on it.
