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.

You bring up an interesting perspective, but it is exactly that the 2.5 is  ubiquitous and the ET is not that makes them, in my mind, the clear winner in terms of market and mind share.

But I don't fault the form factor! :)

PS - In case anyone is wondering, I used to have Focal Profiles, and now use a 2-way.  I still think the 2.5 way speakers have a really great combination of features that, as a speaker "type" is hard to match.

The Janszen Valentinas that I use are a 2.5-way design: cone woofers and a electrostatic element divided into two parts, only one of which reproduces the very top frequencies. I like them a lot, though I'm not sure how much of that is due to the the 2.5-way part of the design.

Mike,

I don't think that being a 2.5 way makes a speaker better sounding, but more convenient! :)
