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, 8, and 16 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 musical driver
I purchased this driver for my first 2-way speaker project, and I couldn't be happier. I am by no means an audiophile, but I thought a speaker build would be a blast, as I love woodworking and stereos, so it seemed natural. All I can say about this driver is WOW!!! I have it in a 25"h x 6.5"w x 8"d tower with a Silver Flute 53-1055 tweeter, and a 2" dia x 6" long port, some polyfill, crossed the tweet at 3k, and voila, gorgeousness!

I also have a set of bookshelfs I just finished with SEAS aluminum drivers and another set of the same tweets. They don't even compare to the clarity of sound the 5.5's put out. I'm assuming it is the enclosure size, so I am going to build towers for the SEAS, but they would have a loooong way to go to match the sound of the Flutes!

I would very highly recommend these drivers. I believe I will end up building a 7.2 surround system using these drivers in every tower! They are that awesome!!!
