Are first order crossovers best?

Yes single drivers do have a mechanical filter being the driver itself.But there's a bit more to it than that.I think Wayne Parham explains it very well here Electrical filters and Acoustic Filters.Also when it's right ..it's pretty darn good.Martin King and Bob Brines have found a method that works well.Though single drivers..especially mass loaded transmission line models won't play at rock concert levels.What they do within their usable SPLs and frequency range is terrific.One of attributes of their design is minimal impedance and phase angle shifts.The difference can be heard if one were to only take time to listen.The distortion levels are the lowest I've heard in my home and anywhere else for that matter.My Magnepans didn't have the speed of these single drivers with 50 wpc,even with a 600 wpc channel amplifier on Maggies.Bombaywalla
thanks for the links ..this is good stuff!

Yeah I love my Driver cone breakup and distortion, too bad it still sounds best! Crossoverless Zu's see system. Not a single full range however, it uses 2 :)

Apparently, this thread has become but a public forum for a couple folks to correspond... ever hear of email? Your dialouge seems to have gotten off topic some.... with point & counter point rehetoric about personal perspectives... though input is more than appreciated, getting back to the gist of the thread might well serve others, right? ...and not be "Who's right & why" sort of thing. OK?

You ever heard of google? Maybe you should do a google search and save us all the trouble.You ask a question and got great answers. The last time I checked this was a public forum. I think some of the links provided are a wee bit more than personal opinion.

Merry Christmas

Blindjim, with all due respect your originaly posted thread wasn't very specific.
