While enjoying the sound of my new P3ESRs very much, I couldn't help wondering what the following imaginary speaker might sound like, built with all-Radial drivers of course. But before I explain what "the following" is, let me (at the risk of being long-winded) explain what gives rise to this idea.
1. I recently purchased a new pair of computer speakers called iNNosound Piccolos, made by a small company in South Korea. They look like another other little speakers made for that application, but they're not: they key difference is that they have not only internal amplification but also an internal DAC, and one 2.5" (!) Peerless driver per side. They sound amazingly good (for what they are) and voices in particular come through very clearly and naturally. They remind of how a simple single-driver setup as found in say a car radio or a TV or a table radio (and the Piccolos are quite a bit better than that) can sometimes sound better than a typical "hi-fi" speaker. Despite lacking loudness and extension, they can sound more real, somehow (though not more real than a Harbeth, of course!). A review of the Piccolo - which is quite accurate - can be found on the 6 Moons website.
2. Another interesting speaker than I've seem reviewed (but have not heard) is made by an Austrian company called WLM. What's interesting about them is that they have a couple of models that use a cone tweeter with a 2.5" diameter, crossed over at a very low frequency (1200 hz, I think).
3. I seem to recall reading a post by Alan about running the 8" Radial driver full-range, and being surprised by how good it sounded.
So, putting all of the above together, I can't help but wonder how a Harbeth with, say, an 8" Radial woofer and a 2.5" Radial cone midrange/tweeter might sound. I expect that dispersion in the high frequencies might suffer a bit compared to a conventional dome tweeter, but might there be other advantages to offset this? Also, if this were a feasible concept, it would truly be an "all-Harbeth" product, which I'm sure many loyal fans of the brand would support.
