More VS testing.
Tried with and without the "extra" iso’s on the MA layer, shown in earlier pics. These are strictly not needed for the MA’s as they will utilize the iso’s under the plattform, just as the BK’s and BOSS do. Good news, all measurements shows better values WITHOUT the upper iso’s. So they are gone
So, MA with 2 layer to left, 1 layer on right. Curves look similar, only higher numbers.
Removed the 18" boss, and tested some VNF options with VS.
First of all, here is the difference in TR with the JBL box in the middle position behind the 2 seat couch(to the right of measured seat), or NF (left pic), and right behind seat (right pic), or VNF.
Again, curves are similar, but higher number for VNF.
Here is the 3 different VNF options, from left to right: 4xJBL sealed, 2xJBL +PR
, and SI18 sealed. Look at the improved Y-axis on the PR
version!! Right in the meat band at 15-30hz!
All these were done with NF box ON THE PLATTFORM!
So i tried to unload the NF box from the plattform, and this was the result.
A lot of TR below 30hz is lost! Seems smart to have the NF’s on the plattform
Here is MA+JBL PR
in left pic and Ma+SI18 to right. Look at how the PR
extends the Y-axis from ~25hz to below 20hz
And here is all TR together, MA+BK+SI VNF (boss removed) with different settings.
To the left MA and BK are on sub1(FF sub channel) and same phase.
Middle is BK inverted phase.
Right is BK on sub2(NF sub channel) in phase.
All curves look pretty ok, but watching content they feel different.
So i settled on the left curve, but i always check some demo scenes after i am done to listen how it sounds, and i found some new clips from The Meg, this is when the helicopter lands on the rig at sea. Timestamp and setup in title.
And setups are same as pic above. Look and the massive difference in numbers in the middle pic!! Only change from left one is BK are inverted! This one is massively more impressive in feel than the "more correct" left setting.
BK’s on sub2 looks very similar to left pic.
Here is the clip right after the above, and here the table is kind of turned a bit.
So ATM i have no BOSS, but with the setup today it feels pretty darn good, with a lot of shake and wooble, and very punchy too.
These test i could do without building somthing, but next project will be the downfiring PR
(will it convert that massive Y-axis spike to Z-axis?), 12" BOSS and BK cantilever.
And then decide final config, LOL.
