OLD SPEAKER PROJECT

smiley33 ...I bought some rather old speakers to find them re-fitted with Eminence 15" drivers.

not sure what I actually have but the following strings are printed on the side of the magnets

PE15 - 3008
15904 8 ohm
67-92250058 G1

If anyone can help me identify these, maybe I could use them for a new build project. Also acquired a McKenzie 8ohm 100w looks dual concentric - in an old stage monitor - sure it will come in handy for something

hope someone can help this newbie dummy and help me get into the 21st century

many thanks .... :oops: smiley33

Have you tried the Eminence Web Site, if it's an old speaker, they may have an Archive section.

thanks - will give that a try now

looked at Eminence site again, seems that anything pre -2000 would have been custom made for other companies (prior to their own public ranges), found out a couple of things mainly that it would be from 1992.

I have e-mailed Eminence in the states and now waiting to see if they can supply any params....

Thanks again for the suggestion Tony

A kindly chap at Eminence let me have some info on the drivers that I acquired - as follows:


15904 was a custom designed OEM speaker that we manufactured to one of our customer's specifications. It is an 8 ohm speaker with a 3" voice coil and a 95 oz ceramic magnet. We do not rate OEM designs (that is left up to the customer to test and rate their cabinet or amp), but a conservative thermal power rating based on the voice coil diameter would be about 350 watts. Here are the T/S parameters:


05-RE OHMS 6.51 13-FS HZ 47.90
06-LE MH .60 14-MMS GMS 55.85
07-QM 5.01 15-CMS mm/N .1977
08-QE .410 16-RMS NS/M 3.3548
09-QT .380 17-VAS LTRS 203.57
10-XMAX MM 1.10 18-SD SCM 856.34
11-BL TM 16.29 19-EBP 116.2
12-EFF % 5.23 20-SPL dB 99.2

Unfortunately I am still trolling my way around the site to educate myself but still trying to get my head around t/s params etc.....

Does anyone have any idea what I could do with these based on the supplied info above or should I give up and try something a bit newer....

George C :whistle:

t/s a little better looking:


05-RE OHMS 6.51
06-LE MH .60
07-QM 5.01
08-QE .410
09-QT .380
10-XMAX MM 1.10
11-BL TM 16.29
12-EFF % 5.23

13-FS HZ 47.90
14-MMS GMS 55.85
15-CMS mm/N .1977
16-RMS NS/M 3.3548
17-VAS LTRS 203.57
18-SD SCM 856.34
19-EBP 116.2
20-SPL dB 99.2

looks like all the info you need is there, use this set of figures and enter them into horn resp, bassbox pro, akabat etc.... and start designing a new box

thanks Bee..... I'll get some of the software and see what happens

Been messing with Hornresp for a week or so now - but find ripping lumps of hair out seems less painful... Akabak and basspro don't really want to download either..

As a PA Dummie I am still trying to get my head around some of the t/s parameters but I am getting there.

the Eminence drivers I have the params for - came in a sealed cabinet...

am I right in thinking that an EBP greater than 100 is better suited to a vented box of some kind?

the cabs are 4.5 cu ft (127 litres) capacity and I wonder about simply making them vented by putting in a port depending on the Fs of the speaker..

I guess I don't really just want someone to GIVE me the answers - however a nudge in the general direction would be brill - if possible

Either way I am having a bit of fun getting my brain working and learning as I go ---

Many thanks
