Rated 5 out of 5 by from Did I steal these?!I purchased 4 of these to replace some 3 1/2" mids in a cheap HTIB surrounds for the garage. I wasn't expecting much as these are only 0.1 cu ft boxes.... Wow!! I can't beleive the sound that comes from these little drivers! Have these wired to a Pioneer vsx-824 as a 2.1 in garage and 2.0 by the fire pit. Might pick up 4 more for outside and weatherproof them. Yep, think I stole them!! Thanks PE!

Rated 5 out of 5 by from Simply amazing.You probably already know by reading other reviews, but these drives are absolutely astounding. I have never heard mids so clear as these, and they're only $15!

Rated 5 out of 5 by from Fantastic!Picked these up to replace the stock, very harsh, mids in my JBL Loft30 bookshelf speakers I use at my computer. Couldn't be happier with the way they sound! Powered by a Lepai LP-2020A from parts express. Definitely a great setup for those of us in a condo/apartment that can't go too too loud ;)

HiVi B4N 4" Aluminum Midbass Round Frame

Can you use these in a car for door or panel speakers?

Asked by: Beachbum
I don't see why not, as long as you high pass them. They will probably only work down to around 100 Hz or so depending on alignment.

What would be a good woofer (6" or so) pairing to 2 of these on a sealed enclosure separate from the woofer enclosure on a tower set up?...  

Asked by: Diego B
Just about every woofer we have will work in this application. Please contact our tech support for more help with this question, tech@parts-express.com or 800-338-0531 x1.

I have 4 of these drivers and i want to build 2 towers with them. Each side will have 2 4" drivers and a Vifa tweeter on a ported box right over a long box where a 6.5" woofer will be.  What volume should I accomodate the 2 4"? 

Asked by: Diego B
The recommended sealed box for a pair would be 0.16 cubic feet, but if they will be acting as dedicated midranges the box volume won't matter with them crossed at ~250 or higher.

If I were to put one of these drivers in a 0.28 ft.3 MTM box with a 1.5" x 2" port, would it perform well? What tweeter, crossover and how much fiberfill would you recommend?

Asked by: salmonline
These will work fine in that volume, but that port size will tune too high in my opinion. If you can fit it, a 1.5" diameter, 8" long port will provide a better tuning frequency. If 8" is too long, a 1" diameter, 3" long port will give you the same tuning frequency. Tweeter choices are very open, just about every tweeter we sell will work with this woofer one way or another. A very popular option would be the Dayton ND20FA-6 crossed at about 3,500 Hz. A couple handfulls of fill will work well, usually we recommend a half pound per cubic foot of airspace.
