Product Details

HiVi M5a 5" Aluminum/Magnesium Midbass

The HiVi M5a has been optimized for an extended and dynamic bass reproduction in vented systems. The driver utilizes a unique one-piece aluminum/magnesium composite cone; the diaphragm's superior rigidity provides immediate and accurate reproduction of transient attacks. This contributes to a more naturally dynamic sound as well as superior definition and articulation in the mid-bass region. Using Finite Element Analysis simulation, Hi-Vi optimized the complete magnet structure and specifically shaped the pole piece to achieve symmetric flux distribution along the travel path of the voice coil, which provides better driving force linearity. It also reduces voice coil inductance modulation and DC offset of the moving system at high power levels. The result is much less distortion and more effective voice coil cooling. The driver may be used in a small closed box as a midrange unit in a 3-way system and the good extension (50 Hz) in a vented enclosure allows for use in a 2-way two-driver or MTM configured system. Recommended crossover frequency region for a 2-way system design between 2-5 kHz.

HiVi M5a 5" Aluminum/Magnesium Midbass
HiVi M5a 5" Aluminum/Magnesium Midbass is rated 5.0 out of 5 by 6.
Rated 5 out of 5 by from Cool look, amazing sound!Built a 1.3 cu. ft. enclosure with a HiVi M8a woofer with a 3" port, HiVi M5amidranges, and Dayton planar tweeter. Pretty amazing sound! Plus, it's the firstspeaker I've built that really doesn't need covers.

Rated 5 out of 5 by from Low cost but amazing qualityI have these guys set up in a home made MTM, ported, upright bookshel style home made cabnits. With 4 of these total, X'ed over at 3000Hz to a set of Morel silk domes, makes for a GREAT combo! Great bass response, and a good passing to the 3000HZ point, in which the tweeter takes over for smooth voice. If anyone is going to do a MTM with these guys, I would recommend crossing these over at more like 3500-4000 HZ, pushing its envolope, but this is for if you have a sub. I currently have a Polk PSW125 sub, as well as a Deffinitive audio center, with 2 cheapo sony's for rears, and these MTM fronts blow all them outa the water!

Rated 5 out of 5 by from Absolutely unbelievable!I have these in some DIY bookshelf speakers, along with Dayton titanium domes, in a ported enclosure. I am currently running them with a 1970s Realistic receiver, and the sound from these things is simply mind-blowing. The specs say these woofers go down to 50hz, but they sound like they are playing lower! Bass drums come through beautifully - with no sub! These speakers sound better than many floorstanders I've heard. Would definitely buy again!

Rated 5 out of 5 by from Really nice 5" driver for transmission lineThis speaker does a good job as a woofer in my own transmission line design. My point of reference is the Jordan 5", a full range speaker well-known for its quality which I've mounted in the recommended Jordan enclosure. The HiVi 5" is in some ways more competent in the bass than the Jordan, (amazingly stable) but doesn't go down as far as the Jordan. Still, a fabulous performer, great value. I've matched it with a 3" HiVi as a squawker, and a Peerless tweeter. The combo produces a sound which is about as clear as I've ever heard in my life, and takes complexity in it's stride.

Rated 5 out of 5 by from A great little wooferI am using 2 of these in a MTM configuration creossed over at 3000 to a Tang Band 25-302SH 1" tweeter. the speakers have surprisingly deep and fast base response and are very smooth

Rated 5 out of 5 by from Very Nice SpeakerI bought this as a replacement speaker for a blown surround sound speaker. It sounds better and slightly louder than the original. It was listed as 5 inches but is closer to 6 inches (including the mounting ring). I had to make some modifications to the original enclosure to get it to fit. I am not an expert in how speakers are measured, so I am assuming it fits a five inch hole. Great product overall!!

For Vented Box, What Size Port Is Best? Thanks

Asked by: wilber1944
I would recommend a port that is 1-1/2" in diameter and 3-1/2" long for the 0.43 cubic foot are space.

Is this speaker shielded...?

I notice the model below this one states it is a shielded speaker perfect for home theater use, this model does not. I am just curious if this model is shielded, and if not is there a practical way to shield a non-shielded speaker?
Asked by: dvdmaximum
This speaker is shielded.
