The absolute best my Cornwalls ever sounded was back in the day when I had a SONY SEQ555ES in the system and could easily check or recalibrate at any time. These days, affordable RTA software with a Klipsch branding would be a superior way to make sure the legacy lives on with the ability of every Klipsch owner to hear their speakers at the level Paul envisioned.
No one else is doing this in an affordable, easy to use manner, and the EQ built into home theater receivers is mostly inaccurate and ineffective.
