Default HIVI for DIY project?

Hi Guys,

What are your thoughts or experience on using the hivi M6N and M5N and M8N drivers as a 2-way or 3 -way speaker project?
Some people love them some not? Metal cone breakup a big issue? Crossover issues? Using soundeasy to design it!

Some people recon the drivers are hard to work with, some love them?

Please give me some straight forward advice regarding these HIVI drivers.

Thanks

I used two M8N as subwoofers in a BMW E46 (not exactly what you`re asking) and did not like them. I have not measured them as it had to hapen quickly but will share a few comments.

There was glue all over the surround and parts of the cone, like someone used a really big brush. The frames are stamped steel and it was thin, some other lower priced drivers use thicker steel. The overall build quality, except the glue phenomena, appeared in tact with their price. Cones looked beautiful.

Thx for the reply but Imy talking more like speaker cabinets.. I have hivi driver with no glue marks or anything but before I design a box for them and spend money on crossovers etc I would first like to know how they perform. Sound quality , breakup etc..

Both the M5N and M6N sound very good, especially for their price point. They will both have break-up since the cone is metal, but buy a robust tweeter and cross around 1,500 Hz with the M6N and 2,000 with the M5N and you can get a very nice design.
As far as the M8N, I thought it sounded good in a 3-way. If I remember, it requires a pretty big box (60L) to go vented and get low. But if you're not trying to get low 30's, you can have a much smaller cabinet design and still have very punchy bass.
I would got with M5N or M6N in a 2-way if it was me. 3-way are harder to design, much more costly for XO parts and if you have a sub already, no real need.

Google Paul C undefinition and he has a design called the Swope where he uses the M5A. Very nice design(s) and XO should give you an idea of how easy these HiVi's are to work with.

Thanks I think I'm going to try them. Breakup can be sorted with the crossover so should be all good. Just as long as they sound clean & crisp with a warm bass.

The yellow fiberglass cone HiVi would be the only I would consider. Otherwise there are just so many similarly priced drivers with easier-to-deal-with breakup and more advanced motors to use the metal cone ones the OP listed. They were neat for their time, but that time is long past.

I would be looking at the M8a. With its highish qts would work quite well in a sealed enclosure of 21L with an F3 of around 60hz. This driver is capable of very extended range and would probably require a largish bass reflex enclosure of approximately 55L by my calculations for an F3 of 30hz.
Personally I have a pair of HiVi M12's operating in a 40litre BR enclosure, in a 3 way set up with a seas midrange and peerless tweeter. Crossover points are 400 and 3000hz. Very happy with the results. After extensive research, this was my driver of choice in the HiVi range boasting smooth, extended useable response up to 1.5khz. They possibly have a warm sound which would also be the case with the M8a's which boasts the same metal magnesium and aluminium cone. The build quality of these drivers is excellent.
Im a fan. Also have a look at some of the Seas prestige range. Great value

Bit off topic but I have M12's too. 4 in U frames xd at 125Hz, very happy with them. Build quality is excellent

The m5n and m6n have been used numerous times. The m8n CAN work in a 2way, but needs some work in the crossover and mated to a tweeter that can cross low. Ive heard one iteration that pulled it off well and that was from Ben Shaffer (Wolf on Parts Express TT).
