Hi everyone,

I’ve published a new 2-way design for those who are interested in a small form factor stand-mount loudspeaker.

The Kensho Two – M2

“Kensho” is Japanese for “seeing nature.” It means seeing one’s true nature; perceiving the self, but can also in Zen Buddhism mean “a brief experience of enlightenment”.

This loudspeaker is a small 2-way using a 5” mid-woofer and a horn-loaded ribbon tweeter in an 8 liter enclosure. As an option the loudspeaker can be built using an 11 liter enclosure.

The horn-loaded ribbon tweeter has its own very unique sound character and it blends nicely with the mineral filled Polypropylene cone mid-woofer.

This moderate priced loudspeaker performs very well and it delivers a very generous soundstage with a large height, width and depth perception.

I love using it with my 35W tube amp, which can play it strong with authority and without problems.

If you hate ribbon tweeter sound – don’t read any further – This loudspeaker will give you plenty of “ribbon” sound.

For details see:

Very nice looking! I'm always on the lookout for a 5" or so woofer with low enough bass to use in a home theater, but that minimum impedance is a challenge to use.

Also, very nice phase matching at and above the crossover section!

What did you end up using for acoustic offsets?

That's a measurement secret...:)

Kidding!

The drivers relative acoustical center off-set is -18mm @ 2.5m for the mid-woofer at tweeter hight with a center to center distance of 130mm.

With other words the ribbon tweeter is 18mm behind the mid-woofer.

In order to partly compensate for that I use an electrical fourth-order cross-over section for the mid-woofer.

The horn mounting of the ribbon tweeter is the reason for the deep acoustical center of the tweeter and a 6 or 8" woofer would perhaps be a perfect match considering this, but then you would have a problem with the high cross-over frequency requirement of the ribbon tweeter.

This ribbon tweeter requires an acoustical fourth order cross-over with a cross-over frequency of 3kHz or higher in order to work properly considering the distortion profile.

Hi Göran, I this is an old thread, I'm curious which do you prefer the Kensho Two -M3 or M3?

Both seem like they would make great candidates to convert to a 3 way with Jeff Bagby's SB acoustics woofer module, what do you think?
