"Ever since my 200 pound, refrigerator size, speakers started showing up in public and in the press I've heard the same thing over and over: 'Why can't you just make some bookshelf speakers that fit in my apartment?'

Of course, it doesn't take a wizard to make a bookshelf speaker and I am constantly experimenting with smaller designs. But I couldn't find a package that I felt really represented what I am after: wide range, present sound with great speed and Iife-like dynamics. I've finally found my solution, and it's an unusual one, so I'd like to give you some context to how I arrived here:

In the early 2000s I was working in Tokyo, where Nom de Guerre had a development studio. I would frequently make the rounds in Akihabara, the Mecca of Japanese 'audio maniacs.' Hino Audio, one of my favorite places to get fresh inspiration, had 4-5 different storefronts on one street. I happened to hear them demoing a very beautiful sounding 12" coaxial driver. The speaker was obviously a new production unit, but had a lot of the attributes of the vintage gear that I'm drawn to and inspired by. I asked what it was and it was the JBL Professional 322c, a 12"ceiIing speaker that's usually installed in large high quality commercial projects Iike airports, theaters, etc. The driver is beautifully built and has a classic JBL sound, but it's mostly unknown in the HiFi world because it's not marketed for this purpose.

On a whim I ordered the 328c, the 8" Iittle brother of the 322c. It didn't take long to realize that this was my solution for a smalI speaker. It has really great transparency and imaging. Wide range enough to stand alone as a 2 way, or play above a sub for the bass heads."
