Product Description
The Viva Voce Speaker Loudspeaker Kit by Jeff Bagby
A 5.25″ 2-way using the Eclipse W520E and Morel, CAT308 Tweeter.
The Story
So how does the Viva Voce evolve from the Continuum?  I had sent Jeff a set of our new W520R woofers and he discovered that the frames of the two woofers were identical. Jeff wondered what would happen if he stuck the Eclipse woofer in the Continuum cabinet? Turns out, they mimicked the Continuums very closely with a minor crossover change.  Then, in late 2017, when the Continuum tweeters were discontinued, Jeff had another idea to swap out the Dayton tweeter to the Morel tweeter – both having the same diameter faceplate. With a few changes to the tweeter network, a new kit was born – the Viva Voce – Living Voice.
The Viva Voce can be built in two different formats – a sealed cabinet like the Continuums or a larger, vented enclosure.  The floor-standing prototype version is pictured. The internal volume is about 16L with the rest of the cabinet acting as stands.
The Morel tweeters have been in production for years and have always been a favorite and excellent substitute for Dynaudio without being harsh. My first audio test for any tweeter is track 3 from

James Newton Howard and Friends. If they reproduce the sparkle of the triangle, I’m happy. The Morel’s do this perfectly!
How Do They Sound?
Like the Continuum, the response with the slight dip in the 300-500 Hz range works very well on a desktop or a stand. The overall response appears to follow that of a lot of Control / Mastering mini-monitors. However, on a pair of stands, it sounds much bigger than it is, which is very impressive. I would put it up against any speaker this size made by anyone for the overall presentation. And it could be advertised as a professional monitor.”
