Rythmik FV18 Servo Subwoofer Sound Demo Report

[Imureh]

Those numbers are from revision 1 of the FV18. The new FV18 revision 2 has 4"' ports instead of 3.5" and you can also get a paper cone version which adds even more output.

You are correct. Brian has confirmed that below 40hz the version tested at databass has identical performance to the rev 2 paper cone and above 40hz the paper cone has +3db more output.

Years later, I just purchased dual FV18s and have dual FV15HPs en route. Old tech in 2022 that still sounds pleasant.

FWIW sweetchaos on ASR has a pretty good database going, too https://www.audiosciencereview.com/forum/index.php?threads/subwoofer-comparison.20494/

Would Audioholics be able to get the FV18 & FV15HP back in for review and measurements 2024? Since then they also had the G25HP developed and I'm curious how that stacks up to the perlisten offerings as well.
