Goldwood GW-215/40/8 15" OEM Woofer 40 oz.
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.

what size and type box best for this woofer ?
would this work in car woofer set up? if so what size and type of box? if used in a 4 way home stereo set up crossed over at 120 hz, what size and type of box?
Probably a larger box, as the woofer selection guide states that a vented box of 60+ cubic feet give a fs of 17hz!! Realistically though, with this drivers specs, the larger the enclosure the better and it would have a smoother response. With this drivers high Q a large(!!) enclosure. Ported is fine
