Since this is an initial review, I'm hoping to see more detailed specs before placing this in either my mental Rolodex or File 13.
A few things caught my attention though...
Talk about other REL subs recreating the “beautiful and almost impossible-to-execute decay patterns as a note descends into echoing silence in a large hall,” is laying it on a little thick. Thank-you, REL, but please excuse me for needing more than vague statements on your products' performance.
The top plate on the HT seems a bit odd. Are we talking about some kind of mass loading of the structure? If so, how is this better than the usual approach of constructing the cabinet out of really thick MDF/HDF that is well braced internally? And why on top? Is it some kind of heat sink too? Doesn't make sense for a Class D amp to generate the heat to justify such a big piece of metal. Eager to hear more...
REL faces tough competition. SVS and HSU are darlings of DI. ML and Paradigm are more upscale, but not too far outside the REL shopper's field of view (especially for shoppers pondering two entry-level subs or one mid-priced one). It's going to take more than a similarly priced product to cut into the market shares of these companies.
It will be interesting to see how these REL products measure and compete...
