5.25 in. MTM +SUB vs. SINGLE 8or10in. + SUB

sorry, I'm confused.Doesn't the M in MTM stand for midrange? How are you not going to use one and still use the MTM terminology?

If you are going to be using a sub, then most definitely keep the midbass units at 6.5" or less, preferably in the 5-6" range. The upper midrange response is vastly better than an 8" will ever have, and you don't need the drivers to go that low in the bass. If you want a specific recommendation, use the Vifa 13WQ, it is a classic and still one of the best midbass units out there. Look up the Ariel by Lynn Olsen (I can't recall the website), it is one of the best uses of this driver and has a ton of info and support. Even if you don't end up doing this exact kit, it is still a good way to start your education.

Sorry, I had a brain hiccup. Lynn Olson's website is www.aloha-audio.com, the Vifa driver is P13WH.

MTM = MIDbass/TWEETER/MIDbass Karls heres my choices FOCAL 5K4211(5inch poly/kevlar) or 7K4411(7inch poly/kevlar) CABASSE 17M18(6.5 FOAM) SEAS W17E(6.5 magnesium) or W18E(7inch) I'm confident the MTM design is the way to go. Do you suggest the 6.5 is the IDEAL size M/B? I would tend to think the 5inch Focal is too small but could the 7 inch Focal be acceptable? Tough choice all 3 are SUPERIOR drivers! I tend toward the Focal 7K4411 poly/kevlar. any votes well appreciated!
