Hi Ian.
I should have said “a” previous version, which were the 2.5-way DSP5200SE like yours (see my photo from 2021) which I still use L-C-R in a home theater surround system. They continue to offer unbeatable performance for the price and form factor, don’t you think? Ask your dealer for the new v3.20 firmware if you haven’t upgraded yet.
My Meridian fandom started with the 5ks in the 1980s !!! then, initially, Smileys here in the New Mexico theater built in 2003. DSP9 are a huge step forward, confirming for me that the company has not only survived a management buyout and the founders’ departure, but done some serious R&D in the meantime.
