Rated 3 out of 5 by from don't push itI had one of these last a year. It sounded very good and moved some big air around. But the amp was 900 watts (real RMS) and a little over the speaker rating RMS. It sounded good right up to when the voice coil opened...

Eminence Omega Pro-18A 18" Cast Frame Woofer Driver

Hello, Is it the eminence speaker inside the Yamaha dsr118w? If No. which one is it? Thanks in advance

Asked by: monrod
We do not have a direct cross reference for what Yamaha uses unfortunately. This woofer will work as long as the impedance matches the original, but Yamaha could give you a better idea of the model used, though it might be slightly different than a consumer Eminence model.

Would this sub work in a JBL Mpro 418 cabinet.  That cabinet came with jbl2241gpl but those woofer are way out of the budget.

I have a par of these in 4 ohm that I purchased from PE. I would like to build a pair of vented cabs for them. Hoping to build a cab with about 6.5 cubic' internal area. Would that be large enough for this driver and if so, what port size and depth?

Asked by: tbinford
These will work very well in that volume. I would recommend two 4" diameter ports that are 6" long for a tuning frequency of 34 Hz.

What gauge speaker wire should I use to connect the sub to the cabinet speaker terminal?

Asked by: Johnny miller
You wont need anything bigger than 14 gauge for connecting this woofer.

Would this woofer work in a HT set-up? What should i tune it at?

Asked by: Jay C
Not unless you plan on only using it for 30hz on up, as a PA sub it was not designed to play below that. The Dayton DCS450 is a much better choice for HT.

will this Eminence Omega Pro-18A 18 work with a swr big ben

Asked by: boof
In short - yes - it will work. The cut-out should be about the same, and the BigBen is deep enough to house it. However, the Eminence Omega Pro-18A is a substantially more powerful and more sensitive speaker than what comes in the BigBen stock. Also, you will find that this speaker will not playback the higher freq like the stock speaker. Since you haven't stipulated what amp you are using it with, or whether you are using it combined with other cabinets (for higher freq etc), it may be wiser to stick with a speaker closer to the original specs (approx 400W RMS@8ohm, 30-2500hz, 91-95db SPL)
