Numbers

In audio, it's often the case that bigger is better.

In fidelity, too. Take the Shun Premier 5.5" Santoku - what's the point, if there's a 7" (we've got two)? Or the Shun Premier 6" Chef's Knife. What's the point, if there's a 8' and a 10, &c? (We've got them, of course. Who wouldn't, they're stunning).

Now for a mid-range driver, however, 5.5" to 6" is about ideal.

Sure you can have your 2" wide-bander bandied about, and multiplied ad-infinitum in a transmission line today. Or, say 15" er in an egg-shell display. We're talking the ....

For only $204.40 at Madisound, however, Scanspeak's 15M/4531K Revelator 5.5" is one amazing midrange driver. You'll get a better mid-range eating healthily, or carrying speakers, than designing them, though that could be a hair-thinning experience, should you like it.

Regardless the drivers by Scanspeak (Revelator) and SEAS (available via Madisound) are long regarded as audiophile favourites.
