HiVi B4N 4" Aluminum Midbass Round Frame is rated 4.6522 out of 5 by 23.
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

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.

What is the Le (Voice Coil Inductance) value of this driver? And is there a way I can derive this myself from available data so I can stop bothering everyone with this question? Or is this something you need the DATS for? Thanks so much for your help.

Asked by: ChagrinFallsScott
The Le on this driver is 0.77 mH at 1kHz. Unfortunately you can only measure true Le with speaker measurement software.

how would this be as a mini subwoofer in a 35W  I-pod dock?

Asked by: speakerfreack
In 0.3 cubic feet with a 1" x 4" port (part number 260-470) this will work surprisingly well as a small subwoofer.

when doing calculations for crossovers should i use the dc resistance or the impedance of the driver?

Asked by: bcaa
The DCR will be the most accurate figure to use for this type of calculation.

Help with wiring ten b4n into a center channel

I have built a sound bar with ten b4n and five tweeters now I want to build matching l&r boxes so I need help with everything from box to wiring to crossover for all boxes the l&r will have 5 b4n and three tweeters each. They need to stay at 8 ohms any help would be great thanks
Asked by: cheecheman
You cannot wire 5 x 8ohm speakers to equal 8ohms. You can wire 4 to reach your desired impedance. 2 sets of 2 paralleled then wired together in series, or 2 sets of 2 in series then each set wired in parallel.Might I suggest you seek help in the PE Talk Tech forum. Also search for Paul Carmody's Overnight Sensation MTM. I have a pair of the OS MT and they are nothing short of amazing. Maybe you could build an MTMMM and substitute a more efficient tweeter and applicable crossover. Generally you do not want to use more than one tweeter per speaker.
