Default sub cabinet for eminance 15" sub

I have a pair of 15" 8 ohm eminance subs that were manufactured for a oem customer by Eminance, Im have the following info on the speakers:

05-RE OHMS 6.94 13-FS HZ 44.57
06-LE MH 1.13 14-MMS GMS 49.34
07-QM 5.32 15-CMS mm/N .2584
08-QE .800 16-RMS NS/M 2.5976
09-QT .690 17-VAS LTRS 266.16
10-XMAX MM 2.80 18-SD SCM 856.34

Just thought I'd put this out there, what kind of design are you looking for? this strongly impacts the size of the ideal box. Thanks Assuming Bass Reflex (ported) I'm not sure if I would try and use these below 50 Hz as 2.8 mm of XMAX isn't much.

Ballpark I'd say 4-5 cu. ft. sealed or 9ish ported to get something remotely flat, my intuition and preliminary analysis tells me it may be futile to build a sub out of those drivers so you may have better luck using it as a low driver in a PA speaker.

What I learned from a short sim: 50 watts at 50 Hz will exceed it's excursion, don't bother making a sub out of it unless you only want to use it for very low output applications.

Thanks sabaspeed521, I really wasn't sure if they would make good subs or not, I got them from someone using them as bass amp speakers, I was hoping th use them on the low end of my pa setup... Eminance told me they would rate them at 150 Watts rms

sub cabinet for eminance 15" sub
sounds like a "Beta" or similar weight (~38-42oz) ferrite magnet motor , lowish moving mass - do they have a 2.5" diameter coil? (Beta15cx had a 2" coil and qts around 0.53) it would be a waste of wood and packing space imo to make a real big box. Some old PA stuff which was vented probably had 3 or more dB peaking due to small motors.

From those specs, I suspect they were for a 15" and horn top box, so okay for small vocal/ band PA, but no use for a home sub.

Well, you could put it in 600 L tuned to 24 Hz to get ~108 dB ~flat down to 30 Hz with 10 W or ~187.4 L tuned to Fs to get ~115 dB down to 40 Hz with 150 W, though severely under-damped as Freddy assumed.
