HiVi B4N 4" Aluminum Midbass Round Frame
HiVi B4N 4" Aluminum Midbass Round Frame is rated 4.6667 out of 5 by 24.
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 ;)

Rated 5 out of 5 by from Excellent Quality!I bought a set of these a week ago and I am very impressed with the quality! I paired them with some ¾" tweeters and a 2 channel 15w amp and the outcome was amazing!

Rated 4 out of 5 by from small but excellent sound.Just received for the first time 8 nos. of this item and still not installed yet on the speaker box, but i did test it by fixing wire then connected to amplifier and I'd compared the sound with my existing 8" mid-range / woofer 225 W speaker made in USA (already fixed on speaker box with crossover), not to mentioned the brand, HiVi B4N 4" with out crossover has more better sound than my existing speaker. The finish in general appearance, workmanship is very good. I am really satisfied with the performance of this HiVi B4N 4" all though still not fixed yet on the speaker box, the sound is very good. Moreover, the delivery with Parts-Express is very fast, better than all other on-line shopping services.

Rated 5 out of 5 by from Very musicalI bought these to (experimentally) replace the drivers in my Pioneer SP-BS22-LR bookshelf speakers. Lucky for me they were the exact same size, including mounting holes, so it was just plug and play. I changed out the left side first, and left the right as stock. Listened to several songs and moved between speakers to hear differences. The original Pioneer driver sounded much more harsh and "fatiguable", with very bright mid-highs. The Hi-Vi, in contrast, seemed much warmer and blended right in. With the Pioneer, I felt like I was listening to speakers, whereas I was listening to music with the Hi-Vi. Not mind-blowing, but certainly not bad for a < $200 speaker setup. It was definitely an upgrade, which is what I was hoping for. Well worth the $30.

Rated 5 out of 5 by from Awesome clarity, natural sound!I built a custom set of two ways using the B4N and ND16FA as a tweeter with the Dayton Audio 3500hz crossover and they sounded phenomenal! I don't know why you would spend more on a speaker. They have a natural, balanced sound.

HiVi B4N 4" Aluminum Midbass Round Frame

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.

hey part express im confused online it says 50 to 3000hz and catalog it says 50 to 10000hz already installed these to me they sound more like 50 to 10000hz what are they? to me they sound more vocals then if they where 50 to 10000hz?

Asked by: confusing

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.

Asked by: salmonline
My bad... 0.28 cubic feet, not 0.028.

Hello, I own a pair of RtR 1530 and I have already upgraded the tweeters with DC28F-8 and noticed a big improvement. Would these Mid speakers work well as replacement for the stock speakers? I am going for sound quality, not huge power handling.

Asked by: Ohiosean
The only thing that might be a problem is the overall sensitivity. The HiVi is quite a bit lower than the woofer and tweeter so if may be slightly drowned out. You may consider something from FaitaPRO instead.
