Members hangwire Posted March 4, 2013 Members Share Posted March 4, 2013 so I bought this for $30 and for a 2x10 cab from a repurposed PA cab [i assume] it is just fine. The ports for whatever/tweeter are just empty space now I poped the back jack plate off before I realzied it was a front mount speaker set up. So i slipped my phone in to snap some speaker back pics: and I have seen no name square magnet speakers in old cabs before... usually they sound not too bad, but this thin black magnet with the cab sawdust on it in the foreground is something I have not run across... looked almost waxy. and the front: the front of the square magnet one^ and the one I am confused about ^ with a really shallow cone and wide middle part. anyone see something like this? is this still a PA speaker? I was thinking of doing one 10" guitar speaker and one 10" bass speaker in this thing... but seeing this weird speaker has me looking for indentification before I take a next step.

Members lefort_1 Posted March 4, 2013 Members Share Posted March 4, 2013 Andrew, Are there any numbers on the frames of the speakers? I can't see them in the pics, but they might be on the portions we can't see. It looks like the rims are front-mounted... you might have to take them off to see the numbers. Once visible, I can give you a manufacturer and date-made. Link to comment Share on other sites More sharing options...
Members hangwire Posted March 4, 2013 Author Members Share Posted March 4, 2013 not as interested in that, more in the weird cone to center ratio and the weird back of that speaker... Link to comment Share on other sites More sharing options...
Members duncan Posted March 5, 2013 Members Share Posted March 5, 2013 Looks like a subwoofer. That's what my money's on. Link to comment Share on other sites More sharing options...
Members imbuedblue Posted March 5, 2013 Members Share Posted March 5, 2013 The dust cap size and weight affects the frequency response of the speaker. It can serve as a mid-, high-frequency radiator. So, the smaller and lighter the dust cap is, the more extended the high end frequency response. Larger, heavier dustcaps acutally lower the driver resonance by sheer mass. Subwoofers tend to be all dustcap and very little cone. This is all subtle though and dependent on a lot of other factors.The striations on the outer edge are there to allow the cone to move freely.Anyway, I'm betting that bottom speaker is just some budget PA/stereo woofer with the label removed. If you Google "10in raw speaker" you'll probably find similiar stuff. Link to comment Share on other sites More sharing options...
Members hangwire Posted March 5, 2013 Author Members Share Posted March 5, 2013 so here are some pics. the square magnet one only had a stamp on the cone and a red blurb and the other one had a label and cone stamp. neither had anything on the rims. this one was WAY heavier than the square wave one Link to comment Share on other sites More sharing options...
Members hangwire Posted March 5, 2013 Author Members Share Posted March 5, 2013 oh and i tried to get an ohm reading for bothg speakers and it really didnt settle with my DMM at all... the closest i could say was 16ohm which is weird since 1 speaker clearly says 8 ohms Link to comment Share on other sites More sharing options...
Members imbuedblue Posted March 5, 2013 Members Share Posted March 5, 2013 That black one is made by Eminence. You can probably email them for specs. Link to comment Share on other sites More sharing options...
Members hangwire Posted March 5, 2013 Author Members Share Posted March 5, 2013 Yup they already email back and said it was a pa speaker they made about a decade ago for an outside supplier... So being a pa speaker, it would be closer to a bass voiced speaker then guitar, right? Link to comment Share on other sites More sharing options...
Members majafa Posted March 5, 2013 Members Share Posted March 5, 2013 the square magnet speaker kind of looks like a bigger version of the CTS speaker that was originally in my Kalamazoo Reverb 12. Link to comment Share on other sites More sharing options...

That entirely depends on the specific model. There are "PA speakers" that are voiced for various different frequency ranges... not all of the 12" "PA speakers" are designed for lows / low mid reproduction, or full range reproduction. Some are targeted just at the mids, or just the lows. See if Eminence can supply you with any of the technical info on that particular speaker, or its specifications. That would let you know a lot more about it, and give you a much better idea of whether or not it is suitable for guitar duties. Typically, guitar speakers have a usable frequency range of about 80 Hz to 6 kHz. A bass driver that was designed for a PA cabinet might only run from 30 or 40 Hz to 300 Hz... it just depends on the speaker, and what they were trying to achieve.

Members imbuedblue Posted March 7, 2013 Members Share Posted March 7, 2013 I'm guessing it's also an Eminence just because it has the same cone stamp and red dot as the other. Link to comment Share on other sites More sharing options...
