Had a session last weekend with some folks and the HB's were a hit.
I had gone to Wal-Mart and found two sets of poof balls. One are what I believe Louis is probably mailing me: they are a lightweight spongey "POOF" sphere.
The other is a "POOF" football which is MUCH more dense and fits in the port perfectly.
I have a less than optimal setup in that since we have kids, I have been using 3I's in a bookcase/entertainment center. Old picture but gives you an idea. Kid friendly, not so much sound-friendly.

The HB's replaced those and they needed to have the ports sealed or they were too boomy. I also have a Deep Hemp which really does integrate wonderfully with both 3i and HB. FYI, I added the same spikes seen on the Hemp sub, to the platform it is sitting in the pic.
So, we decided halfway through the night to swap out the Genalex re-issue 12AU7s with the E80CC (which I normally use). These were all tested on my Amplitrex.
Then since John had brought his JW Audio Cryo cables, we had to pull the pseakers out and we ended up leaving them on the floor with spome makeshift risers; about 3 feet out into the room.
Then we unsealed the ports.
These Hoyt Bedford's sing. Proper placement of course did so much for these, but honestly, as I think Bronal stated upthread, the tone is just incredible unsealed. Maybe this matters more with some types of music. We tried briefly putting the footballs back in but they sounded a bit too tonally constricted. More experimentation is needed (see below).
Switched off the Deep Hemp and was SHOCKED at how good the bass sounded. My room is pro-treated but failrly well off: I have (7) absorbers and carpet, couch/chair, Acoustimac baffles, a large Art Panel, etc. so maybe this helped with the boominess perceived by Bronal. My room appears to be larger as well and is "ported" with an open wall to the rest of the house.
We listened to a lot of music. We didn't even have any stands, which I am looking for (planning on setting them up for critical listening only). I reluctantly put the speakers up last night, knowing my wife would be home with our 1-year old, so I set them as far away from the wall in the bookcase as to still be stable, and I put in the light weight Poof balls as opposed to the footballs in an attempt to tune the sound a bit better.
I will next play with the JW Audio Cryo wire which so far is a serious contender for replacing my Clear Day cables. Thanks to Louis for designing, building, and pricing such a wonderful and NEW speaker. I imagine it would be rather easier, in this economy, to regurgitate a design etc. so hats off.
Now I really have plenty of volume with the Mini-Torii; more than I will ever need.
