Had time to play with the BB last night and it’s really growing on me. Think it’ll do wonders for tight muscles in my back too. Bonus!
Awesome on the BB. Cool as well on the settings I'm using on the HB. I'm also running (which I forgot to mention), a negative HS at 12hz/-5hz/0.9Q and raised overall levels in the miniDSP by 5db in addition to the other to pick up the single digits more while keeping everything else about where it was. This could be done with another LS and no level raise, but chose to add the raise in this way for this boost.

You may or may not like the settings I use in your system, so you'll just have to mess with it. Also, same goes goes for the settings on your BB. Levels, shape of curve etc. Then try to get the HB and BB to feel as one encompassing/engulfing TR experience working together if that makes sense.

For example, in Iron Man when he is testing and tuning his Repulser/Blasters in his hands right before he suits up to fly over and kick butt after seeing that dude on TV. You know, that mega hit where he shatters the glass and the one right before. It hits so hard that it feels like its ripping my insides apart LOL. Insane punch and just the right amount of sharpness, with such a feeling of crushing power within the body and chest area from the pressure of PV and TR combined. Today it actually hurt my insides and chest area and one of the first times that my system has really, really scared me. Like seriously scared me that it could be hurting my chest or something internal. I kept on with the demo though all the way through to where he suits up, then breaks the sound barrier (which is beyond insane (just as much or more so than the first couple of blaster shot I was talking about)), then the mega single digit hit that follows, then probably the most vicious 2-3 second TR hit of all right after that single digit part. It hurt my chest area (like beyond good hurt this time) and blurred my vision!!!! I was relieved when it was over actually LOL. It was so intense I realized I was squirming in my seat like I was almost trying to get away from it or something. This whole demo was the most insane thing by far that I’ve ever experienced!!!!! And it was at only -20mv

So yeah, I can’t believe I said that it might be too intense, even for me with such a thirst for this feel that I thought I may never be able to get enough, even with all the crap I run together that REALLY helps when combined. Don’t get me wrong though, I absolutely loved it, but I do need to back off the sealed BB in the mix a little bit, or I may be paying the price at some point.

I don’t want to end up with a heart attack or something. I know that sounds crazy and I feel kind of ridiculous saying what all I just did to try to describe the feeling of it all but is the best I can do. Words don’t really do it justice though. If anything, now, I think I need to pick my single digits up more to match the above intensity levels, even though 6 JBL HoverBOS kills in the singles!!

Please guys, don’t take all that the wrong way, I’m not trying to brag and say my system is the best thing ever, but for me, it’s by far the best my system has ever performed and surpassed my craziest expectations. There are some pretty crazy systems in here now that I’m sure would give the same kind of experience, maybe even more so.

To say I’m thrilled is a MAJOR understatement and I owe a lot of it to this forum and all the great contributing members here with ideas and enthusiasm that push our systems to greatness and beyond. I’m so very thankful for this and happy to be a part of it!!!!!

Ok, so I just spilled out a LOT of stuff there but is how I truly feel about it all. Hopefully it doesn’t make some of you too sick to your stomachs LOL
Yeah, ok so this is your version of "being happy with my setup and just enjoy some movies", ??? LOL, you have never been more active than now !!! What’s gotten into you??

Just kidding, really cool that the sealed BB was such a improvement from open baffle. This was what we discussed in PM on how it would work. Well, obviously it works, LOL. And as usual, the way you put it forward, you know i just have to try this too, Hahaha. I’ll see if i can get some test done next week

Does this mean your VNF’s are a thing of the past now?

3x18" cantilever HB next ?

Not according to 3ll3 that is one advantage of the qvibe/viberry, no heavy sensor(phone).

LOL, yup !!

But i kind of agree with you, at least as it is getting at these levels. Heck even the couch is airborne with no load on it, LOL. But like you, i really don’t like pins in my bum

And also, it is a LITTLE weight on it, if you remember back in the Viberry thread i tested with just sensor, sensor taped to the raspherry, and then taped to the powerbank. Sensor taped to raspherry was the smoothest curve.

I am cross posting updates in my thread and here. If anybody minds, let me know, and i can link instead


Got the VNF back on the sled I just went out in the garage and found the legs i made for them earlier, and used them to space them up for clearance between the hoverboss JBL magnets and SLAPS. Again: not pretty! But it’s just for testing



3" + clearance now, should be plenty.




You can see the HB JBL’s, the BK and the VNF/ SLAPS here, LOL.




Made another run with Qvibe, and it is really starting to get wild in the single digits, LOL. 142dB at 7hz ! ! ! (Martian airlock clip again)



Impressions:

Well, even with all this the 6x hoverboss is just crushing it !! UN-BE-LI-EV-AB-LE ! The rest of the TR devices adds a couple dB each here and there, but they are simply no match no more for the HB, LOL.
And the VNF on top of sled adds the same SPL and punchy sound as before, not as much TR, but again, what surprises me is, how much SPL the HB adds! Not so much down low, but from 17-20hz it is very audiable, so it adds SPL to the rest too.
And luckily it doesn’t seem to be any cancellations between the SLAPS and the rest, either SPL or TR wise, so that’s good

Isn't this outside of the audible range? How can it be "very audible" from 17-20hz?

I meant from 17-20Hz and UP

«Not so much down low», as in not audiable below 17-20hz.

And as usual, the way you put it forward, you know i just have to try this too, Hahaha. I’ll see if i can get some test done next week

3x18" cantilever HB next ?
LOL …yeah, kinda ate my own words there saying I was done and content last week after adding the HoverBOSS to the mix huh

BB had to be tried, as more feel in the chest like I was getting in my last system was a place in my current system that still lacked in comparison. Then guys started talkin it up in here about a driver mounted to the seatback, then you know what happens next Hahahahaha.

Seriously though, too easy not to try. And yes, like we were talking about in PM, I had a feeling it could be crushing but don’t think we realized just how crushing with some PV added to it sealed. Sometimes things just fall into place once you get going with experimenting. I think it’ll work just as good in your system as it did in mine. We’ve got different style seating for sure but should still really work great I would think. Pretty crazy just how super powerful it can feel, but no surprise actually when you think about it. It’s a DIRECT shot to your body, or upper body I should say, with nothing else in the way really, not only TR but that crazy potent PV that is basically strapped on your back. It just doesn’t get any more super-duper nearfield than that LOL

So, for my next move and what to do with my VNFs. I don’t know actually. 3x 18” canti-levered HoverBOSS could be crazy for singles and a little above. There is definitely more stuff I could do yet. I still haven’t even tried the BK attached to the BB like I was planning, which could end up being yet another direct kill shot to the upper body in their own way. I’ve also kind of thought about 3 separate Hover Platforms for each seat instead of one big one. That way, it’s not all jiggly and moving like crazy when the wife or daughter is watching with me. My daughter can’t sit still for long before she’d wiggling around and stuff lol. That’s about the only thing I don’t like about the tubes of hover or even the squishy isos I think. So, that would fix that. It may even move more freely for singles without the platform being so wide and heavy.

IDK though. I should probably just leave it all as it is and just enjoy the hell out of it with the VNFs sitting a little lower an on the floor like they are now to make room for the BB on the seatback. I’m probably crazy if I decide to mess with it anymore. But I guess that’s already been established LOL. Pretty much everyone in this thread is “crazy”, no offense anyone hahahaha

BTW, killer TR in your readings and new vids man!! Just killer!! Thanks for posting the progress with your monster TR rig my bro!!

No, just on the outside of the seatback. I wanted to try this before I cut a hole and was so amazed at the difference, I’ve just left it like that so far. I still just can’t get over how crazy good it is. You have to try it in your system!!! I can’t imagine anyone being disappointed in it.

Was checking out the sealed BB in the mix tonight on some different stuff since the wife hit the hey early. I’ve already seen Ford vs Ferrari a few times, but went back through some sections of it. This movie with the BEQ just feels absolutely amazing!!! Huge and awesome feeling ULF from the HoverBOSS (BKs and MAs help too) and with the addition of the sealed BB in the mix, I could feel every engine rev, zoom by, gear shift, rumble etc in my chest BIG TIME!!! It’s is so realistic and exhilarating that it’s actually like you’re in the car experiencing it for reals, maybe even better LOL.

Guys, I just cannot recommend this sealed BB enough. I think there is no way it wont totally blow your minds and take your already fantastic TR systems to another level of awesomeness.

I can’t wait to hear what more people think about it when they get it integrated into their systems.

I think m0j0 said something similar about his BB with the hole in the chair version, that it just does something to your experience that whatever gear you may already be running and however great it is, (HoverBOSS, MAs, BK LFE’s, or VNF’s or all of them) it just can’t quite do. I think mainly because it’s directly coupled to your back for the TR and the PV (particle velocity) being so close to you that it just enters your chest and upper body area. The combo of this TR and PV is just nearly beyond words it’s so good.

That said, the sealed BB all by itself is missing a bit of what everything else combined below you feels like too. I wouldn’t be totally happy with just sealed BB alone. Well, It’s still great but missing a bit what everything else adds as a whole for the totally enveloping grand experience. At least for me. At the minimum, IMO, HoverBOSS AND sealed BB need to be the backbone of your TR, then if you wanna run BKs, MAs or whatever else in the mix, then add that too. I would NOT want to be without my BK LFE’s either though LOL. And then there’s the MAs …gosh I love them too LOL I may have a sickness I think hahahaha

I sealed the bottom of the seatback in the middle seat so I could jump into the other seats for an easy comparison




It definitely feels better with it sealed at the bottom, the seats that are still open just feels like the vibration from the driver moving, the sealed one makes you feel it more inside your body and also has more power deeper down.

It also has a lot of spl, I measured in rew and the BB had more spl around 50Hz than my subs combined, lowered the gain by 7db and added a 7db LS at 30Hz and it doesn't interfere with my FR anymore

I tested a few scenes from TIH, the sonic cannons right when they first get fired up before that ULF part you can really feel that extra sharpness and punch that the BB gives, and in the street fight you can really feel the sharpness from the footsteps and machine gun when they jump to grab the helicopter in slow motion

Here is a picture with the VNF's in place



And here with the BK's

Because I can now control the air in all of my HB tubes at ones without removing my couch, I tested what pressure felt best. I thought that more pressure would feel better but it didn't. I tested 2 scenarios,
I pump the tubes on till the couch was just floating of the isolators when I sat on it and pump the tubes so the isolators are still on the grond without sitting in the couch. With the first scenario the BOSS gets slower and more bloated. I find the second scenario much better the BOSS is much faster and feels tighter, but still has the great TR because of the tubes.

Just an update for anyone that cares. I'm on day 4 of having opened up the mount on my chair and fully eliminating the SPL. I basically went from a 12" mounted on a board on my chair back to something more like 2 1x4's mounted on the back. The original mount felt great but my ears were not feeling too good with it. The current mount is great. I never feel ear strain any longer and just feel the great tactile results from it. For soft-back seating, this seems to be the way to go. I have also removed all my other shaker systems and am only running the 2 12's in the sofa.

On another note, I discovered the DSP in the inuke3000 DSP and discovered the app to control the DSP via PC. I wrote an interface that allows me to do simple things via my PC universal remote now such as turn up sub gain, turn up shaker gain, load a preset. I also configured it so that different presets are automatically loaded when I start my music player vs when I start kodi. Working on that has been super fun also

Gee, think there might be some interest in that project around here?

Isolators definitely need to be touching to get a natural and commanding feel from the HoverBOSS. For those wanting a scientific way to dial in the air pressure of your BOSS tubes, I posted a method here.

This method provided the best HoverBOSS experience based on lots of testing and measurement data of platform bending. Remember, the platform still needs to be very rigid and supported properly, especially with HB and the 100-150 lbs of shaker force now available for each driver. The isolators provide that rigidity

SPL from BB can be a nuisance for sure. It's because SPL doubles each time the driver distance is halved to your body. With BB, your head is basically right next to the subwoofer Even the mightiest of far field subwoofers would have a hard time keeping up with BB if the SPL isn't mitigated somehow

I've found BB (currently semi-open baffle) combined with HB makes my far field subs somewhat unnecessary. That is, until I move to another seat without BB. Then those far field subs come back into the mix and enhance the experience once again.

I went out today and bought some plywood and a 16" inner tube and started making some sawdust. I should be able to start comparing the two versions sometime this weekend. I have an iNuke3000-DSP and will power each BB version separately and adjust levels if needed. I'll also use aron7awol's recommended LS filter to flatten the iNuke response to 4Hz, but won't add any other EQ during the comparison.

A pic of my seatback bottom is attached with the dust cloth pulled back to show the left side of the cavity opening. One thing I didn't notice before is a 1/2" layer of padding between the leather and thin plywood on the back. This extra layer gives the appearance that the back is slightly curved, but as far as I can tell, the plywood itself is completely flat. I plan to keep this layer of padding in place for the sealed inner-tube version (the extra padding below the leather should actually help make a better seal). For the psuedo-sealed (m0j0) version, I'll probably pull out this padding after I cut the hole in the back so the BB plywood baffle can be bolted flush against the seatback.

My thinking now is to not add foam to seal the gap at the bottom for the psuedo-sealed version. I'm worried if I restrict the airflow too much, the BB driver may be exposed to potentially damaging pressure changes if someone decides to suddenly throw their weight onto the seatback. With no one in the seat, I estimate cavity volume to be about 3/4 cuft. When someone is reclined with their weight on the cushion, this volume is likely reduced by at least half. That's a lot of displacement to ask a 12" driver's suspension to absorb. In any case m0j0 is getting good results with his BB, and I doubt his seatback is sealed either. It doesn't seem likely any recliner manufacturer would intentionally make their seatbacks air pillows.

I'm looking forward to hearing/feeling how the two versions perform. Both will be SPL challenged at low frequencies - the inner-tube version because of the tiny volume the woofer sees, and the psuedo-sealed seatback version because of front/back wave cancellation. I may also try an alternate sealed version. Instead of sealing with the inner tube, I'll add 4" deep sides on all four edges of the plywood baffle, and then bolt that to the back of the seatback to complete the sealed box. For my size baffle, I should be able to get about 3/4 cuft of woofer loading.
Darrell.....looking forward to learning more about your findings with both configurations.

With either configuration, I think you'll find the limited SPL will be a welcomed benefit because BB is so close to your ears

I have a thick carpet pad. Using the 4 quarters method should I press down on the quarters into the carpet/pad as far as they will go?

In my experience, a tube of pipe insulation foam works well, too.
