best 4.5" midrange drivers under $1K

yes I agree with the ringing of the non paper, but have you tried excels? They certainly dont hv common weakness compared to other nonpaper..hence my search yet on nonpaper

Accutons cant go low unless the 6"-7"..even 5"one cant go as low as others in my experience

but have you tried excels?

No. But I am old school and a woofer or mid/bass with a voice coil diameter barely bigger than a typical tweeter kind of rules them out for me. You are talking thermal compression big time, IMHO - even at modest levels.

but try excel whenever wanna opt to metal without ringing with still gives you involving and sweet sound

yeah it's 4in afterall..i cant go bigger cause dont wanna to rework much on enclosure and my listening space is limited if not small

The cone may be 4" but have you looked at the specifications for the voice coil. It probably uses a 26 MM diameter overhung voice coil - a diameter no bigger than most dome tweeters. These tend to get hot as the small surface area and long coil in a short gap and which means that heat dissipation can be a challenge. The metal phase plug is intended to help cool the pole piece but it is the voice coil that will get the hottest.

What struck me was the low distortion of the

Tangband W4-1337SA ($55)- click on harmonic distortion

It seems the be even lower than the ATC unit.
