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.

My set of "augmented one-way" UniField 3 MII speakers are pretty great.  So I nominate this design for consideration.  For what that may be worth.  Most likely nothing, to anyone other than me.  Highs, mids, lows, imaging, beauty both in sound and visually.

Eric, I understand you are in an apartment, and your post does cater to listeners of the same sort. But, I feel, if a speaker ( system, actually ) cannot handle musical peaks in the 110db range ( of course, using recordings that have wonderful dynamic range, not just playing loud ), whatever the design, I would not want it. And yes, I am a horny kind of guy, lol. My ears, btw, still measure well, for a 65 year old. Enjoy ! MrD.

Totally understood! You should get what is best for you. :)


But we can't really call Horns the most popular speaker type either. :)


Blessed are those who can afford a dedicated listening room.

Best,

Enjoy my 2.5 way Vienna Acoustic Mozart Grands very much. Well more than that. Erik with your parameters I agree a 2.5 way has a lot going for it. It can be looked down on by some because it makes a few more compromises it seems like from an explanation from speakers builders, but not much on sound

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.
