lately i've been giving this mtm design some thought. GENIUS!! Think about it.... Why try to extract low hzs from a single 8 or 10 inch woofer. let a great sub (CABASSE 12 or 16 ) worry about the below 40 hzs and the dual 6.5's can do the rest. think about it. with dual 6.5's you get more than twice the surface area over a 10 and almost 2x the obsolete 12. dual 6.5's give a relaxed presence to the many different midbass hzs. thrown at the driver. the 10 is doing his very best but some complex music has got him comming and got him going. the 21st century speaker is begining to take shape. heck its here! thanks to a guy by the name DR. JOE APPOLLITO. the question of superior dome tweeter vs superior ribbon tweet i can't judge until i hear the RAVEN-2. the superior dome tweets to do battle with the RAVEN-1 and RAVEN-2 would include the SEAS MILLINIUM the top FOCAL ADT CABASSE. the winner takes on the PHILIPS R8T isodynamic. got a note from a guy that belongs to a group that designs equipment and tests to determine a drivers qualities. really complex stuff. he said he's can't stand when someone votes big on one driver and shoots down another. then he lists about 10 super high tech variables that can affect a drivers potential. i agree with him to some extent. but a lab is not going to price its superior driver about the same $ as its entry model. ain't no way. AND we all know that some amps and cdp sound superior to others in the same price range. same with drivers. some are better than others in simular circumstances. so take time to find out which drivers you're buying. don't just buy by speaker name. buy with knowing WHICH drivers your getting. or better choose your own. yep thats what i'm talking about. heck you can't design your amp or cdp, you buy after researching the product. same should go for THE MOST IMPORTANT COMPONENT IN EVERYBODY'S SYSTEM. when you go buy a speaker from your local hifishop ask him what is the name and model# of the drivers. he don't know! IF a commercial lab DID offer these same drivers in a design you're looking to fork out $5K to $15K. and would they sound as good?? i got my opinion. you may think its bias but first go listen to your speakers. all right blast away
