These are not tweaks IMO they are a well designed room treatment alternative.
WAF is off the charts. They work. They have a refund policy for 30 days, no one is pulling your leg.
What can one do for a room for $299 ? Not much. Phase one just may be enough.
No rush no hype all I am conveying here is try them. With TWL plus cords no need for Alan Maher crystals. Just to much of a good thing. To many crystals can muck it up, right Pete ?
