Synergistic Research HFT's


Not to open up a can of worms but I am reaching out to people who actually have tried the SR HFT's or Black Box.  I am building a new house and my two channel room is my great room / kitchen.  The dimensions are 20'W x 40'L with 16' cathedral ceilings.  This is not the best 2 channel room but it worked well in my last house.  So the question I have are there any tweaks that I should be considering to improve the overall sound performance?   I know the obvious answer is Acoustical Panels but that won't fly in my house.  I already have all of the Perfect Path Technologies products for my system.  I already have SR Blue Duplex's but might change to the orange.  So now I am looking at what I can do to improve the sound in that kind of room without Acoustical panels.  The rest of my system includes:  Canary Audio Grand Reference 2 mono amps, C1800 Pre-Amp, InaKustic 3500P Conditioner, Lumin X-1 Dac/Streamer.  My cables are all upgrades also.  I have been looking at the SR HFT's and Black Box.  Comments?

Hmmm... some tough criteria, conditions. Some of these solutions also may not be acceptable, but here goes:

Portable/movable sound panels. Take em out when listening, roll them away when not. Use for personal enjoyment of system, and keep tucked away when entertaining. 

Window treatments or retractable sound fabric "wall" for window/door 

I presume you already have considered sizable floor rug and potentially stuffed furniture with cushions, etc. 
I would try synergistic UEF Panels and Dots - very musical - put em on the walls as outlined in instructions for a couple of days - and then remove the panels - the sound stage collapses. You will want them back in. 

I tried the  HFT's - they work as  advertised. But I preferred the UEF panels. YMMV. 

I have 8 UEF panels and I think 10 dots. 
Hoping if anyone can advise. I have open back speakers, i intend to buy the HFT speaker kit to place on the speakers. For the walls, which would suit open back speaker, the HFT or the UEF Dots?

I am from Australia so it would be hard to make use of the 30 days trial.

I dont have a dedicated music room so it is an all in one TV, home theartre lounge room so there are 2 sets of speakers the open back only for music and HT LCR and surrounds.

I have 3 sets of the standard HFTs. I can confirm what was stated above they work as advertised.
