Hi,

I just picked up four EV DL15X drivers that I was hoping to use to build some passive subwoofers (two or more). The problem is that I don't know how to interpret the specs well enough to figure out what size cabinet might work well with these. Any suggestions or advice is welcome.

I'm hoping to match them to a set of JBL LSR32 monitors. The JBL's go down to 60 hz, so I figure the EV's should be able to supplement them well enough to 'fill out' the sound a little more on the lower end, but I'm kind of lost beyond that.

I'm thinking of experimenting with an active crossover for the subwoofers, but that is something I will also have to figure out as I go along. If plate amps would be better, then I'm open to that as well.

Thanks.

There's a lot of info on the data sheet including a couple of box recommendations, 4 cu ft tuned to 35 hz or 6 cu ft tuned to 30 hz. There's even predicted response graphs for the recommended enclosures.

But with 4.1 mm xmax they won't get very loud so it's a good thing you have 4 of them.

Personally I probably wouldn't use these for subwoofers due to the very limited displacement potential but they would probably be pretty good in a 2 way with a waveguide tweeter.

I was half afraid of this. So these drivers are probably best used for something other than a subwoofer, is that right?
 
Depends what your goals are. If you don't mind having 4 boxes that are 6 cu ft each and you don't need to get lower than 40 hz and you don't need extreme spl you could go ahead with the recommended box.

I wouldn't, but it would be better than the average garbage subs sold in big box stores.
 
Everything about the specs of those drivers makes it look like a low-mid driver for 2 or 3 way mains.

If you wanted to make bass bins for prosound use, I'd say find another driver. But given the monitors you're matching to, I'm guessing you're indoors and probably not looking for PA levels of sub.

Certainly workable, in that case, provided you don't mind some large cabinets.

Might see if they sim well in this cabinet? The eminence drivers are similar in intended purpose and parameters. This will work great for crossing over around 60hz. Just a thought. As stated earlier the xmax is what limits your ability to make bass. Using all 4 drivers, you can make quite a bit of it, but it will take a lot of cabinet space.
