Our living room is very small, so the 3DP waveguides are in the basement 'system', where it's dark, cold in winter, and noisy when HVC is running. Small Syns take up almost no floor space and don't dominate our little room.
Bill, you need to build a listening room in the basement! HT!? My basement was the same when I moved in, nothing, no noise control, ... But now I have a listening room to-the-max. It's soundproof! Imagine that! Took awhile, but it is doable.

Hi Bill, could the latest iteration of this printed horn (HF + Mids ports only) be used in a two-way? If so, what frequency are the mids crossing over to the woofers?

But your house is huge!

In Portland, 600' is considered "big"

^^ like he said.

Also, my basement has 7' ceilings and I can't get more than about 15' from the furnace unless we have the whole HVAC setup reworked. So I just took it as a personal challenge to get something sounding good in a small space.
I do wish I had a big basement, though

I should have rephrased this; I understand that the crossover frequency is dependent on the interaction between the horn and woofer. What I meant to ask is an estimate of how low the unity waveguide holds a pattern with HF and mids only.
