Product Details

Vifa NE315W-08 12" Subwoofer Speaker

The Peerless/Vifa NE315W-08 12" subwoofer's open cast aluminum basket design minimizes internal acoustic reflections and helps cool the neodymium motor. An additional heat sink supplements thermal dissipation. The cone is constructed of a coated natural wood fiber, with a butyl rubber surround designed by finite element analysis for linearity of performance. FEA techniques also contribute to the motor's copper cap, which reduces inductance and extends the driver's upper frequency range.

Vifa NE315W-08 12" Subwoofer Speaker
Vifa NE315W-08 12" Subwoofer Speaker is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from Best woofer in three way floor speakerThis is the best woofer I have ever heard in a three way design. It is the clean musical, and how no unwanted boom or coloring.

Rated 5 out of 5 by from 4 Custom built subI purchased this sub woofer and mounted it in a Parts Express 3 cubic foot Gloss black (SWC3-BK 3.0 ft³ Subwoofer Cabinet Gloss Black). I did considerable enforcement of that cabinet and ported it with a 4 inch port 17 inches long. A decision made with help from parts express tech adviser. I powered it with an external sub amp that has 250 watts @ 8 ohms (apex SR). The finished sub goes very deep, and has incredible punch. It is musical and still able to do Home Theater work with ease. Tight with out boom. The product description claims "incredibly deep, clean bass fundamentals" and it lives up to that.

Vifa NE315W-08 12" Subwoofer Speaker

What crossover point is recommended between the NE315W-08 and an Usher 8498A?

Asked by: Auburn81
These drivers can handle a wide crossover range, anything from 300-600 Hz will work well.

What box and port size would this woofer require?  Also if I were to use 2 in a three way what you be the efficiency (db)?  

Asked by: gold
I would recommend a 3 cubic foot enclosure per woofer with a single 3" diameter, 17" long port for a tuning frequency of 25 Hz. Two woofers wired in parallel with give you 6 dB more output.

Would this woofer work well in a ported 3 way design?   Or is more suited for subwoofer applications?  

Asked by: gold
This will work well as a woofer in a 3-way. I would recommend a crossover between 350 and 450 Hz.

Sealed Cabinet Size

I have just ordered the 12" Vifa sub and am looking to purchase a sealed cabinet (not ported) for it. What cabinet that PE sells would be best suited to the characteristics of the sub, when run in sealed mode ? I prefer sealed to ported due to sharper bass notes.I have a Peerless 12" XLS sub that I bought a few years ago and is serving me well. It is in a sealed cabinet and sounds great. Will the Vifa measure up to the XLS in a sealed cabinet ?
Asked by: AVKESQ
The Vifa will work well in the same sealed cabinet as the XLS, around 0.9 cubic feet. The XLS will have more output capabilities due to its longer excursion, I cannot say how else the two will differ.
