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.

Eric, I appreciate your friendly and adult response, as I did not indicate anything negative, only to say, what I like. And yes, horns are an old design. But, as I mentioned on another thread a few weeks ago ( I believe it was your thread " designing a pair of 60K speakers), I brought up the famous and popular Dahlquist DQ10, and, with no response, btw, from my post. I indicated it had relatively inexpensive, off the shelf drivers, and was a 5 way design. Everyone I knew ( even myself, a horn user ), owned a pair. I asked for an explanation on why they were as wonderful as they were, and I know folks who still think they are ( I am not one of them ). My belief is all speaker designs can be wonderful, and as a given, nothing is perfect. But, I believe you said it best, and completely agree. " Whatever works for you ". Enjoy ! MrD.

Erik is right about a 2.5 way having a lot going for it. It is perhaps the best choice for audiophiles that must share living space and audio gear (no dedicated room). I put my Dali Epicon 6s in this camp. No need for a sub, darn near full range and big, gorgeous sound. My wife is good with the looks and size so this 2.5 way is a win/win in our home. Many want that full range sound and must place the speakers in a shared living space. Based on his criteria Erik is spot on in my estimation.

As an aside, placing my rig in our open to kitchen living room was the best thing I ever did for enjoying music. We have music on all the time and now my wife enjoys with me. So sweet! I am no longer alone in my my music cave!

You can see our shared room and rig under my virtual system.

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.

The Sound Labs and Acoustats may play @110 dB, but my old Quads sure won't ;-) . Not sure about the Sanders, Music Reference, Martin Logan, Kingsound, and others.

The wharfedale diamond 230's are a 2.5 way speaker that received numerous positive 5 star reviews from 2 or 3 publications. At only 600 bucks on discount a steal!
