HiVi B4N 4" Aluminum Midbass Round Frame
HiVi B4N 4" Aluminum Midbass Round Frame is rated 4.7 out of 5 by 20.
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.

Rated 5 out of 5 by from WOW, WHAT A DRIVER!!!!I built a pair of Paul Carmody's "Overnight Sensation MTM" speakers and these are the recommended mid driver. These things really sound great. You can't go wrong with these. They love power and sound fantastic.

Rated 5 out of 5 by from very good speakeri love this little speaker, in the right box it sounds way bigger then it is. i bought two for a center channel i also used a paradigm tweeter i had laying around. this was way better then the paradigm 4'' inch speakers before and a third of the price. sound is very clear, never harsh, pretty deep bass for a speaker this size. very good buy

Rated 5 out of 5 by from Very Nice small midbassThe HiVi B4N 4" Aluminum Midbass is indeed a very nice driver at a GREAT price. Initial modeling revealed some very interesting results. Looking at the parameters one would think that this speaker was designed mostly for ported enclosures. However, beyond 1K the SPL becomes quite erratic in a ported enclosure suggesting that there might be some midrange shout since graphing shows areas at least 3db above zero.The surprising thing comes when you model this driver for a sealed enclosure. The SPL output peaks completely flatten out making a smooth curve that begins to drop off after 1K. The output curve shows that crossover should be between 2-3K (from a SPL point of view). Also the volumetric requirements of the sealed enclosure are quite modest resulting in a just-right sized box. I would suggest that these drivers make for an excellent MTM design. By wiring two in parallel you will see a 6db gain (about 91db @ 2.83v/m) that makes matching a tweeter much easier without employing a L-pad or resistor.Since the F3 for this configuration is rather high this suggests that a satellite/subwoofer configuration would be ideal. In this situation a standard second order Linkwitz-Riley crossover works very well since bass delivery to the B4N does not muddy the sound – if anything it improves the impact of drums and fast-attack bass. The end result of such a configuration is a high power satellite that produces excellent imaging, precise yet fluid upper spectrum reproduction that should be ideal for small to mid-sized listening environments.

i want to build a box for two hifi b4n and one vifa 1" tweeter what size should i make it and crossover need i to use

Asked by: cheech
I just completed a project with the B4N woofers and different HiVi tweeters. My box enclosure was 15.25 h x 10w x 7d outside dimensions with 3/4" material. I ported the system with a 1.5" port tube 3.4" long. I'm very pleased with the result.

What size disconnects should I use with these?

Asked by: Mike985
As a rule, I solder all speaker connections and restrain wiring with tie-wraps to the speaker frames. This not only eliminates the need for lugs, but mainly for troubleshooting; knowing the speakers are soldered, a failure [no sound] is likely something else [on the outside]. This goes especially for HT ceiling and wall installations.If you must use lugs, industry standard is 1/4" spade-lug. Some are smaller, 3/16" and recently I have been seeing 1/8" terminals on some import speakers. Buy a bag of each [mates, slip-on crimp or solder lugs] and you'll be covered for all your DIY speaker projects.

hi. can someone help me with speaker box design i volume.?

Asked by: rooobal
EBP for this driver would be about 88, which would make it suitable for either a sealed or vented box. in a sealed box of about 5 liters, f3 would be around 76 Hz with a total system Q of .717 (very good). in a vented box of around 8 liters, the f3 would be about 42 Hz with a 1" X 3" port (tuning of 47 Hz). personally, I would lean toward a sealed enclosure -- you'll lose a little in efficiency (and bass extension), but the system will have greater power handling and less distortion at higher power levels, generally. good luck!!

I noticed the manufactures response graph and the Parts express graph differ. Which one is a better example to follow.

Asked by: Greg H
They are both accurate although measuring configurations may be different. It appears Hi-Vi uses a bit more smoothing to their graph which will make it look different. I would use our graph for design purposes personally.

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.

Will this work?

Greeting, I have been looking around the site for several weeks and enjoy what I see. I have a few questions about a JamBoxx I am Building. I have plenty of woodworking skills so my basis are covered there, I just need help on the electronics end.Here is my plan.This unit will be for use in my garage while I am working. I am not looking for max volume etc, just a great clean sound at low volume, at minimal pricing.The size of the box will be 20 inches wide by 10 inches deep and 10 inches tall.The amp I am using is theLepai Digital 2x15W Mini Amplifierwith Remote USB MP3 SD FM (Lepai Digital 2x15W Amplifier with Remote USB MP3 SD FM 310-302)The speakers (2) I was considering are theseHiVi B4N 4" Aluminum Midbass Round Frame(HiVi B4N 4" Aluminum Midbass Round Frame 297-429)And I will be using the MP3 output of the amp to play music from my Galaxy S2.Here are my questions.1. Are these speakers gonna work in this box?2. Do I need to port the box or seal it?3. I have tried many of the online speaker box calculators, but cant figure out how to use them, is there a very simple one?4. Are the speakers I have chosen enough, or do I need to add tweeters?5. How hard would it be to add something that would allow me to pick up AM radio (so I can listen to the ballgames)? And what would you suggest?
Asked by: danconway327
This speaker is not nearly enough for a box that size. The box is far too large for this speaker. I would suggest looking at plans for the "overnight sensations" here on parts express. I would use a tweeter if you decide to use it though.
