shaolin95 is on a distinguished road
So the VTF-3 MK5 HP goes lower and with more output than my vtf15 Mk1 ?

I own 2 of the VTF15 Mk1 (and one MFW15) for 3 subs right behind my seating area.
I was surprised to find this information from Sound And Vision measurements:

The VTF-15H’s close-miked response with one port open, normalized to the level at 80 hertz, indicates that the lower –3-decibel point is at 24 Hz and the –6-dB point is at 18 Hz. The upper –3-dB point is at 162 Hz with the Crossover switch set to Out.

While the VTF3 MK5 shows this:

The VTF-3 Mk5 HP’s close-miked response, normalized to the level at 80 Hz, indicates that the lower –3dB point is at 17 Hz and the –6dB point is at 15 Hz. The upper –3dB point is at 144 Hz with the 4” port open, 3” port blocked, EQ = 1, Q = 0.7, and the Crossover switch set to Out.—MJP

Which is very close to the VTF15 Mk2!

So if I want those super low frequencies, getting the VTF3 will actually be a decent upgrade???
