2 EV or not to EV ?

Good day, everyone.

I have a couple of questions and thought this would be the best community to get some answers.

A couple of years ago I had a couple of JBL 2226's, a couple of EV DH1A's and a couple of B&C DE250's laying around. I found someone online who knew how to build and finish quality cabinets, combining these components and, along with a custom crossover, bringing new life to my listening experience. They are part of my home theater setup along with Focal and Polk and being powered by Arcam.

The frequency response is beyond what I though it could be. The 2226's are crossed over around 800Hz where the DH1A's carry to 3Khz and the DE250's take it from there. The crossovers have pots so I can adjust when things are either a little bright or not enough, and I absolutely love the sound and how low they actually play.

While watching a movie the other day, the sun was poking through my blinds and hitting one of the 2226's. There was a lot of low-end rumbling and explosions in the movie, which I like, but noticed the cone on the speaker moving quite a lot. I know this is normal, but I started thinking about maybe having a dedicated subwoofer(s) to help support and complement the 2226's and cross them over around 50-60Hz.

I have some other components just sitting in my basement right now doing nothing but collecting dust...they are 3 Electrovoice EVX-180B's.

I've read some other reviews on them and asked my friend about designing something to house 2 of the EVX-180B's, as there were favorable comments on them playing down to 27Hz. He, in turn, stated that the JBL 2226's could probably use the help around 50Hz, but that the EVX-180B's are not much better than the 2226's, and that I should consider selling them and getting something better.

Can anyone here assist with any information (pros/cons, different drivers, different cabinet designs, etc.) about this? I'm open to ideas and it would be greatly appreciated.

Cheers

Hello,

I believe the speakers are tuned to 40 Hz and there is a filter set to 30 Hz as of right now.

I was hoping to utilize 2 of the EVX 180B's in one cabinet, set somewhere under or beside the the flat screen. Kind of like a TL880, but am open to different cabinet design as well.

I have several options and frequencies to set a highpass on the mains once I add a sub, so that's not a problem.
 
It's not so much the volume as it is being able to clean and clearly hear and feel all that was recorded. Sometimes speakers need assistance at certain frequencies. In this instance, I would like a subwoofer (or two), powered by a separate amplifier, to handle anything below 50-60 Hz. Doesn't have to be loud, just clean.
 
Below 50-60hz subs operate in pistonic mode where xmax alone determines how much spl can be generated, and that means these drivers will be power limited to a fraction of their thermal rating. But two 18's in a typical home listening environment should be able to produce lowend you can feel even with only a couple hundred watts so this is worth a shot IMO.

Two separate subs should produce better results too, in smaller rooms cancellation nodes are more prevalent and having the ability to put drivers in different spots will break up those nodes into smaller areas thus smoothing out coverage better.
 
Doesn't have to be loud, just clean.
There are certainly other 18" that have more excursion and power handling that work in smaller boxes than the EVX-180B, but they are plenty clean, and don't sound bad pushed past Xmax.
Two each in 10 cubic foot tuned to 30 Hz at 200 watts (each) should hit 124 dB, about 10 dB more than I'd ever use at home..

That said, since you have three, and "the more the merrier" as far as room placement, (and displacement) might as well use them all!
