Top tip for the Vandy lovers with external subs (2WQ or Sub3), I recently upgraded my M5-HP filters to M5-HP TEF filters. This is the same high pass filter circuit and capacitors used in RV’s M7-HP filters in a more modest enclosure. The difference is SIGNIFICANT. The bass is so much tighter and punchier (traits often at odds with each other). The mids are more airy and expressive. Accuracy of all musical details notched up a level. I use them with 3A Sigs with two 2Wq subs. Highly recommended and a modest investment compared to the sonic returns.
RE: VLR-CTs. I used these in my room with a Sub3 at AXPONA this year. I received many positive comments about the sound in my room from attendees that spent days listening to systems 10x to 25x the cost of my room equipment. They like backwall so placement is friendly. They are great by themselves in a small room. Add a sub and they continue to perform in medium to medium-large sized rooms. At AXPONA, I was asked repeatedly if the sub was “on” or “connected”. This wasn’t due to limited low frequency representation, rather, how seamlessly the VLR-CTs and Sub3 worked together.
