Synergistic Research HFT and FEQ Room Treatments, and XOT Crossover

Howard Kneller has posted a review of the HFT ($75 each) and FEQ ($750) room treatments, and XOT crossover ($399/pair) at SoundStage! Ultra. His conclusions:

“Synergistic Research’s HFT, FEQ, and XOT work, but their effects were not on the usual scale of audiophile tweaks; e.g., “I definitely heard a difference.” In fact, relegating these products to the category of “tweak” would be a mistake. They fundamentally improved the sound of my system. I suggest that you rush to a Synergistic dealer to give these remarkable products a listen. I doubt you’ll go home empty-handed.”
