Hmmm so you have a traditional (non mini boss) and are using NO isolators under the riser but you are using isolators between the riser and the seating? Is that what you are saying? I'll have to try that on my back row since I have a traditional riser back there.
What numbers are you using on your negative high shelf?
Ah ok, Xbox should be able to get Atmos too if Atmos is offered on certain titles.
Yes correct on the boss riser. It’s a full size and just sits on the carpet and pad with NO isolators, making it sealed (or sealed for the most part). So I guess not really a BOSS riser any more since it’s no longer open baffle. It’s way more of a sub riser now, just using the carpet and pad of the floor to seal it from the bottom, instead of an actual bottom on the riser itself.
Kind of crazy I guess since floated with isos is what is prescribed, but works better in my system like this as a sub riser. I like the feel of it better and measures better with VibSensor as well with more authority down super low. Pretty crazy that I get quite a bit more ULF TR out of it like this (even with no LS) and doesn’t ever bottom (at least at my highest listening levels, which is around ref bass levels at my loudest).
The feel is a little different than floated on isos (partially less bounce feel I guess you could say), but feels extremely realistic to me. It also doesn’t have the jiggly jello feel either, which you may or may not like.
But yes, I also am running a few isos on top of the platform in between the Crowson MAs in the back. Mainly because there are so many little feet on my HT seats, that they are needed in the back since I have the MAs (2 per seat) on the back inner framing feet of the seats. The isos go in the back outer feet. Then just using blocks for the front of the seat feet instead of isos. I did quite a bit of testing and this felt the best on my seats setup like this. So just these isos on top in the back (4 total for 3 seats) soften the TR just enough making the ULF TR feel a little better than without any.
Out of all the BOSS platforms and configs I’ve tried, (even 3 of my 18’s mounted cantilevered) this one just felt the best setup like this. Measured the best too, at least down low in ULF territory.
Yeah try it, you may really like it. But then again, may not be as good as the way you have it floated now, especially since your riser is quite a bit bigger and heavier than mine and with less drivers. Might be worth a try though. Ya never know.
Maybe the reason it works so well for me, is that my riser is fairly small at 40” x 8’ and only 6” tall, plus has 6 of the 12” JBLs in it. Just 3 of the drivers works pretty darn good though, but 6 is definitely more powerful.
So for the negative HS, through a lot of experimenting with a variety of good movie demo, I really like it set at 34hz/-10db/Q 0.9. This rolls it off pretty good above 35-40hz, but can be adjusted pretty easy for more gradual slope from low to to high if desired, and or just bump up or lower where the frequency is set. I mainly just use the negative HS in place of the LPF because the timing is better with my VNF subs. I do the same on the MAs, although I have the MAs set at a lower frequency. LPFs introduce delay, whereas HSs don’t (or not nearly as much anyway).
But yeah, pretty crazy the amount of fantastic feeling TR the full size BOSS riser can dish out, especially down low, just setting on the carpet and pad with no isos. Surprised the crap out of me actually LOL. That so goes against the way is prescribed and ‘suppose’ to work . But hey, I’ll take it no matter the reason. Gotta go with what feels the best I say, whether it ‘should’ or ‘shouldn’t’ be better.
Just to give you an idea of the TR hat this thing is capable of setting on the floor with no isos under it, check out these VS measurements with BOSS/subwoofer riser only (no VNFs or MAs in be mix).
White Noise 0-50hz on the left and EOT intro on the right (where I have it set in the mix at ref levels) and pretty easily pegs the Z axis LIMIT and hits over 1e-00 down towards 10hz. And without bottoming too, which was a nice surprise as well. Plus no LS on the bottom end either, just the negative HS (well actually on these graphs I had it set as LPF @ 35hz with BW 12db/oct slope, but sma Eli d of shape with the negative HS).
More pics and info about it all in my thread, but thought I’d at least post these two VS graphs to show what it can do with no isos. Pretty crazy I thought, and ended up loving the way it feels. Your floated BOSS may give similar readings though and may feel better to you. Good VSs or not though, you gotta go with what feels best. But it’s nice when the objective lines up with the subjective. It does happen sometimes lol
The EOT intro VS reads real similar to Sott’s subriser with his 2 18’s (although his is set to g’s and mine to m’s) and follows the PVA of that intro just about perfectly, like we want. That was pretty cool too I thought that they read so similar. Ha, guess it’s basically like setting on a sub cab itself and can be pretty darn good for TR
