Product Details

HiVi M6a 6" Aluminum/Magnesium Midbass

The design of the HiVi M6a woofer has been optimized for extended and dynamic bass reproduction in vented speaker systems, and the driver will reproduce sound with great precision. The M6a utilizes a unique one-piece aluminum/magnesium composite cone, and the this advanced diaphragm's superior rigidity provides dynamic and accurate reproduction of transient energy. This contributes to a more naturally dynamic sound, as well as superior definition and articulation in the mid-bass region. The high temperature voice coil former, air transparent spider, and venting of the coil promote good power handling.

HiVi M6a 6" Aluminum/Magnesium Midbass
HiVi M6a 6" Aluminum/Magnesium Midbass is rated 4.8333 out of 5 by 6.
Rated 5 out of 5 by from Outstanding Value.I purchased these HiVi MId-Bass woofers a few weeks back to use in a custom enclosure. Being that I'm only a hobbyist, I brought them in to work to obtain a professional opinion from one of my co-workers who builds professional Bass Cabinets in addition to owning his own recording studio. When I showed these and their specs to him he was very impressed. When I told him what I paid for them he was floored and now this guy is a parts express customer as well.

Rated 5 out of 5 by from Very happy with my purchaseBought 4 of these, and I couldn't be more happier. I replaced the 6 1/2 2-way stock speaker from my 4 new Polk Floorstand Speaker. Very good bass response, and crisp middle range. Absolutely transformed the Polk into a completely different system.

Rated 5 out of 5 by from Ultra compact sub.I built the Cerberus ultra compact subwoofer from plans available online. I substituted this 6 inch for the 6.5 inch specified for this ported enclosure. Test signals at 35Hz were audible but from 40Hz on up surprising good. Tested in my living room it could do the job but was not intended for a space that large. In the 8' X 10' workroom it was built for it is outstanding. For a 6" economy speaker it moves a lot of air without straining.

Rated 5 out of 5 by from WOW THE BASS!I built a pair if tower speakers with 4 of these in each with a HI Vi RT2H-A. After going to stereo shops and listening to what was available I decided to build my own speakers. I do have allot of money in these ($1000) but I used the higher quality crossover components and Kimber wire inside. These speakers sound better than anything I could buy by far!!! At times they sound like subwoofers as far as the bass goes. I compared these to Klipsh towers and the Klipsh wont hold a candle to these. I have had friends come over that have spent way more than I did on speakers and they say mine sound twice as good as theirs do and want to know what company makes them. LOLNow I need to finish the cabinets.

HiVi M6a 6" Aluminum/Magnesium Midbass

Is this one the off white satin color or the brushed copper? several pictures are of the satin, but they are old pics. concerned because they will go in a dark red cabernet stained speaker.

Asked by: hangnail
The current picture online is actually not right, they have the flat satin finish and not brushed copper.

Will this driver work in a free air application (car door)?  Thank you!

Asked by: extraclassic
This driver will work okay in a free air application although I would not expect much below about 60- 80 Hz from it. A high pass around this frequency is recommended.

I want to build a cabinet with 3 of the M6a's. How do I go about calculating air space in vented cabinet when they share same air space?

Asked by: Mark83
the box size would triple for three of them. Most of the software like bassbox pro will also calculate boxes for multiple drivers.

cone color

how different is the cone color compared to the HiVi B3N 3sthanks
Asked by: ikymagoo2
The cone colors and finish types are quite different, the M6a has a solid color and is a satin type finish whereas the B3N/3S is a brushed aluminum type finish and is more copper colored.

will this work

will this speaker work in the Dayton Audio B652 6-1/2" 2-Way Bookshelf Speaker box if i add a port ?
Asked by: hiviman
Hi HiViYes it will work and very well.Tuned @ 50 Hz with 1 port 3" dia and 10 inches long and one end flanged.43 Hz knee point -3dB, Max SPL @ 35 W 100.There is a peak of +4 dB @ 60 Hz.Pretty loud for a bookshelf.Total inner vol 17 Liters.The rear port air velocity is slow enough, so @ 35 watts will not "wooff" the port.The frequency can be tuned lower and the peak will desapear, but the lenght of the port will make the speaker size a little big for a bookshelf.Good luck,David
