SEAS Excel W18NX-001 (E0042) Nextel Cone 7" Woofer

I purchased four of these units for an MTM tower speaker experiment with an extended bass shelf response. Internal volume of each cabinet is approximately 1.32 cubic feet with a 3 inch precision vent at a touch over 9 inches in length tuned to roughly 38 HZ. Due to the internal cabinet damping material I have chosen( .5 inch foam) this may also be contributing to a bit more internal volume the drivers are responding to. For whatever reason on some forums other enthusiasts had made the claim they could not get any appreciable lower extension from these drivers but I will simply state that isn't my case at all. I find myself now turning off my sub woofer just out of intrigue at the smooth lower extension I am getting with these units which is easily reaching down into the high 30 HZ territory and perhaps a bit lower with usable output. These are great sounding drivers with a unique tonal quality and detail that is greatly enjoyed. They look the part too and one can cast aside any doubts as to whether the aesthetics of these units will deter from the visual impact of whatever project they are taking on. Well done SEAS!

These drivers were used a 2-way TWW tower speaker. After burn-in, I found that they were very smooth sounding speakers. They have a tube-like bloom in the midrange that gives a very smooth texture. All the detail is there. I would put these in the Sonus Faber type of sonic signature category. Excellent choice if you are after that type of sound.

I'm using it in the car combined with SEAS Excel T25CF-001 Tweeter (a good price for an Excel line driver). Madisound has provided me a crossover plan and I have to say that this is the best driver match I ever had. The nextel cone provides softness and musicalitty. Even with some spectrum peaks, normally expected in cars, the overall audio quality is impressive. Strongly recommended.

Used these in a 2 1/2 way design along with the T29CF002 tweeter. Could be the best sounding woofer Seas makes.

'I have had these woofers mounted in my car doors in the stock location for the past year. They were recommended to me by several people, and have provided excellent results. They reproduce everything thrown at them flawlessly and without adding any coloration. Imaging is excellent. They will play fairly low, relieving the subwoofer off all but the true sub-bass. I have them crossed at 60Hz and at 2.5khz. I have the Seas W18NX mated with the 1" ScanSpeak Illuminators and the two make an excellent combination. Someone should design a home speaker using the ScanSpeak 1" Illuminator and the Seas W18NX. Yes, they are a bit pricey, but you get what you pay for. If you want one of the best woofers available today, get the W18NX. Highly recommended.' Review by Shiv Naimpally. Posted by Madisound.
