The Silver Flute line offers exceptional value, build quality, and versatility.

The woofer cones and dust caps are made from a special mixture of wool and paper fibers. These wool fibers help reduce cone resonance, and give the woofers a slightly warmer sound than traditional paper cones.

The woofers have durable rubber surrounds and robust cast metal frames. The large voice coils are vented through the back plate.

These Silver Flute woofers are available in 4 and 8 ohm.

Consider this product for home stereo, surround sound, autosound systems, and commercial line arrays.

Please look at the mechanical specifications carefully as terms like 5", 6.5", and 8" are generalizations.

Very good value

Reviewed by AlexTF1 on 03/01/2016

Considering the actual price, this piece offers a pleasant result, but one not consider this a low bass woofer. They shine more in high bass-midbass-midrange area. And can be used without crossover in no-over-the-top systems.
Sounds better than price suggests.

Is worth on a budget systems.

Outstanding Value!

I am using these in my front doors in a 2-way setup. I built custom fiberglass enclosures, and I am in love.
The enclosures are just about .75 cubic feet and ported with 2" PVC.
I am never going back to weak mid-bass, ever!

Good value driver

Reviewed by [email protected] on 11/22/2012

Used these in a project to build a pair of loudspeakers using fairly inexpensive drivers and see what could be done with cabinet and crossover deign. The result was failry pleasing. The units aren't great below 60Hz (see response curve @ http://phase-n.blogspot.com/2011/08/phase-iv-complete.html) and there's a bit of a hole at about 180Hz though this is probably a cabinet design problem since the hole wasn't there when I tested the driver resposne in free air. I've been listening to the speakers using this driver them for over a year and am not unhappy.
