Those are the M8a. Browse around that forum and you will find several projects using them - WT and WTW in ported boxes as well as the big dipole where they are used as mids. Good drivers but they need to be crossed pretty low because of a resonance at about 2500 Hz. Jon crosses to the tweeter with a quasi-8th order Cauer elliptic filter at about 1250 Hz.

i have searched after some projects but no luck yet... maybe its just me that cant find anything... i now the filter should be around 1-1.2 not going to be a problem...

i will look around the site again

I built the large ported M8n's here:

The M8n is extremely similar to the M8a, but the basket is stamped not cast.

Im Using the M4N along with the Tang 2" with phase plug in a .75 ft^3 ported cabnit and i am shocked at the bass extention of the little 4" driver. Im shockes that it has somthing you can almost

call punch down to 45 hz. I am a big fan of hivi now, for the price there better than vifa imho.

With apologies for any confusion, I didn't build the speakers pictured in the first post of the link I attached - the ones I built are shown in the last page of that thread.

The ones built by Tibor in the first post are extremely nice.

According to a couple design programs those M8a are more aligned to a sealed enclosure. Anyone tried that ?? 59 hz F3 or there abouts
