Barry, I'm sure your Heresy sounds very good. You say a bass reflex is louder, yes, but your closed version goes deeper into the bass, below the Helmholz resonance that makes the cut on the bass reflex. Your efforts to find a suitable subwoofer were certainly a great challenge that you mastered. It is not so easy to harmonize the speakers...
We can also talk about the SME. So many exciting and interesting topics smile

I'm not sure, you know the Klipsch Jubilee? I was under the impression you thought I was comparing Westminster to a "Klipschorn"?
The Jubilee is a two-way system for the home, or three-way in the cinemas. The high-mid horn starts at 500Hz, it's a combination of conical and Tractrix. The horn is a CD principle (constant directivity). From about 6000 Hz the phase plug of the driver takes over the wave guidance. At the crossover frequency, the radiation of the bass cabinet and the mid-high horn has approximately the same pattern.

The bass is the legacy of Paul Klipsch. It delivers much less distortion than the old Klipschorn and the impulse is very fast because it works with 2 x 12 inch drivers. It opens to the front like the Westminster does. If I can find it, there was an AES paper when the Jubilee was introduced about 20 years ago. Because of the large area of the mid-high horn the Jubilee sounds even more like a Westminster than the old corner horn. And the bass is incredibly dry, airy and physical down to 40 Hz. Here is a picture when I had the pair in my living room. And...all of you who don't know speakers of this size, we're not talking about a rock music club (yes, it would work as well with this speakers) but about mimosa-like nuances, if you connect a 300B for example.

A photo when they were in our living room. Paul personally introduced the speaker to CES in 2000. He was well over 90 years old then. Roy Delgado developed the Tractrix/conical horn for it.
