Speaker of the Century Award Goes To ....


The 2.5 way speaker.


You guys probably thought I was going to fanboy over a brand, and I'm not. I'm going to fanboy over a speaker design. IMHO the 2.5 way speaker is THE ideal high end speaker for the majority of enthusiasts.


First, what is a 2.5 way? It is a speaker with 3 drivers, but the mid range lacks a high pass filter, so  it shares output with the woofer.  It has a number of advantages over smaller and larger speakers:
  • Similar footprint to stand mounted 2-way speakers
  • Ideal bass output for apartments and modest homes
  • Easier to integrate than big speakers
  • No subwoofer
  • High sensitivity compared to a 2-way using similar drivers
  • Reasonably priced


A number of brands have taken this approach including:
  • Focal
  • Joseph
  • Monitor Audio
  • DIY kits like the Klang Ton Ophelia, and Zaph Audio

So for the average enthusiast who is not a San Francisco billionaire I argue here (for the sake of an argument) that the 2.5 way speaker should be considered one of the great technical innovations in terms of users and results.

I am 65 and can still hear 18,000 Hz just fine. I do not normally play at 110 db but I do have a sound level meter and the system will go that loud w/o distortion. A comfortable loud volume is 95 db.
Tweek, properly set up Acoustat 2+2s with sub woofers and 200 watt class A amps are so much better than Pipe Dreams which could not throw an image to save their lives. 
BDP  We use to stack quads and with Hartley sub woofers. We could get 95 db out of them but we still use to blow one a week or so. 
Teo you are so wrong. I get 110 db out of my ESLs and the only limit is amplifier power. You will never find a dynamic loudspeaker with near the realism of a floor to ceiling ESL which obviously you have never heard which means you have absolutely no idea what a top 1% system sounds like.
