Ozzy - I own 10 HFTs and a FEQ. They are crazy good so your DIY version being even better really intrigues me. I understand you use 1/8" copper caps. I found the Hareline cones on Amazon. You said to use the "large" cones. The "large" cones are 1/4" according to Amazon. Is that the correct ones to use? The other options are medium at 7/32", small at 3/16" and x-small at 5/32". Yours appear to fit so well I just want to make sure I order the right cones to fit the 1/8" caps. Thanks again Ozzy!
Synergistic Research HFT + FEQ
I heard this tweak at RMAF and brought it home on a 30-day free trial. Unfortunately it turned out to be a real system killer. I had 20 of the HFTs and tried them with and without the FEQ, using a ladder to put them up and take them down repeatedly. I couldn't believe how awful it was. Made it hard to enjoy my otherwise excellent ~$45k system.
I had a similar experience with their Quantum fuse. Never did trust anything with "Quantum" in the title. HiFi Tuning Supreme fuses, on the other hand, made my amps sound significantly better.
