This debate over self made speaker unit is like comparing apples and oranges. Who in the entire hifi business is designing the speaker units themselves and all the electronics in an active way?
To my knowledge there is only Cabasse who makes "special" active filtered and multi amped loudspeakers while making their own (and good) speaker units, not sure the amps are 100% cabasse though.
The flagship Cabasse "Sphere" loudspeakers are active with seperate amp and filters, but of course this fancy system cost 150 000� or more!?
Even then when you compare the DSP8k's and the Sphere, the M's are way more sleek and home friendly! according to the M30 brochure "At Meridian we believe that high quality sounds can best come from small loudspeakers. [...] The reasons are that a smaller loudspeaker, apart from being easier to install, radiates sound in a more 'familiar' way - more like a speaking person - and this results in an easily interpreted sound, producing solid stereo images and the illusion of being at the performance. A smaller loudspeaker also gives less colouration due to cabinet vibration."
Now I know why I love my DSP3100!
