Just to reiterate my thought about the SLAPS:

Ok, so a i have now loaded my TR Sled with(amongst other) a 4xJBL cantilever BOSS + the 2xJBL+1x PR VNF/BOSS box on top of that. And it works awsome.

But somehow it just seems i have more gas in the tank....i still feel using 8 total JBL’s pumping free air, seems like a waste, altough it works great for TR, and then i end up with just 2 VNF boxes with "just" 4x JBL’s total(+2x PR) for NF SPL.

So the Pr setup i use now is:

2x 4cf NF boxes each with 2xJBL +1 x downfiring SLAPS M12. MMS for BOSS action= 544 x 2= 1088grams.

And then 8x JBL total in cantilever BOSS. MMS= 179 x 8=1432grams

= 2520grams total MMS for the whole couch.

What i am thinking is:

Use the 3x NF boxes each with 4xJBL as i had it from the start, only adding 2x SLAPS m12 downfiring in each box, so MMS=544 x 6= 3262 gram TOTAL (no BOSS).

This way i will get more MMS for better BOSS function, AND still have all the 12x12" JBL’s for VNF duty making SPL. Plus the added low end from the 6x SLAPS.

The WINisd looks rather similar for the 2xJBL+1xPR as it does for the 4xJBL+2xPR, only more midbass for the latter, but no disadvantages.

Yellow is 4x sealed, blue is 2+1PR, and red is 4+2PR. Both active and passive drivers behave similar in both PR setups, stroke wise.



And instead of 1 xPR working at ~60-80mm stroke, i will have 2 per box!

Sounds like a no-brainer in my brain
So, according to Winisd, doubling the drivers and PR’s in the same box will behave pretty much similar, the stroke of both driver and PR will be the same, so it will be 6 SLAPS pounding instead of just the 2 i have now.

Well, passive radiator surve the same purpose as porting a sub, it makes it more efficient around tune and requires less power to reach the same SPL. It has advantages and disadvantages compared to sealed, just as ported has, but you can search that online I am no expert, i just normally "wing it", LOL.

Normally because of the massive MMS on a PR you need to use two of them and mount them opposite sides to balance them, but that is presicely the effect i am tapping into for VNF and TR duty by mounting them downfiring. So i am getting all the advantages(and diasdvantages for that matter) of a "ported" sub with the added side effect of the increases TR. This only work if the SLAPS is mounted downfiring, otherwise it will cancel out SPL, so it is a pretty spesific use of this kind of config for a spesific purpose.
Simply put: i am going against normal recommendations for this, to exploit one of its disadvantages

For a normal farfield sub with SLAPS, you need to consider other rules.

Thanks, so if I'm reading that right with the SLAPS in a down firing position you will get less SPL but increased TR, or am I reading that wrong?

Two of my VNF boxes has been used with one SLAPS until now, so had to get creative when i reconfigured for two SLAPS pr box.

Strangely enough, one of the new cutouts fit in the old center cutout, completing the circle for one cutout, only requiring a slice for the second circle to make both new circles complete. Lucky i guess

I wasn't sure how to interpret this, so hence my question. I wanted to clarify if you were doing this to get more TR even though there is a lower SPL (disadvantage). I just wasn't sure what the disadvantage was, so again just trying to clarify.

I said if mounted OTHER than downfiring it will cancel SPL

So, if you have farfield subs and nearfield sub, they all have to be in phase, right?

And if you have TR devices, the TR from them also has to be in phase with the TR from your NF’s and FF.

Altough my NF when fitted with just the JBL’s does contribute to TR because they are so close, it is mostly in the Y axis, and by adding the SLAPS downfiring i kind of get a mix of a regular NF box and a BOSS plattform, adding a lot of TR in the Z axis, which is what we want.

If for example i mounted the SLAPS upfiring, the SPL would be the same, but the resulting TR from it would be in inverted phase! And to get the wanted TR in phase, i would have to invert the whole NF box, and thereby the SPL from the NF would be out of phase with the FF’s!

So for the TR from the SLAPS to be in phase with the sound(SPL) from the NF’s, you have to mount the SLAPS downfiring

Does that make more sense?


EDIT: a bit more reading about PR:

https://www.css-audio.com/single-pos...ter-Than-Ports


EIDT 2: a lot of info is earlier in the thread when me and Aron spitballed about the SLAPS.
I first got the SLAPS because i wanted more SPL down low from the boxes i already have, and then the BOSS came around, and my idea evolved to a NF/TR combo that i just had to try. And the rest is history

Yes that makes sense now, thanks for explaining it! Thanks for the links I will read up on it and go back earlier in the thread as well.

No worries, just ask if there is more


Well, i got done with the SLAPS conversion today. Went from 2xJBL&1xSLAPS to 4xJBL&2xSLAPS pr NF box. So, no more BOSS per say, it is now built into the nearfields in the form of 6xSLAPS Kind of hard to get a good pic underneath there, but here is 6 SLAPS in a row :



A bit of a hack job getting it spaced right and heavy as hell lifting it in place, but i made it.

No time to test it proper yet, but will provide more info when i do.


Oh, and it seems Viberry is up and running too, so will be fun to test that one out too, when time permits

Got some tweaking done today on the new JBL/PR setup. And... this was fun, holy crud the upgrade from 2JBL1PR to 4JBL2PR is MASSIVE!! I has A LOT more TR than the previous setup, even though i have REMOVED the normal BOSS drivers! I now have INSANE WOBBLES ALL THE WAY DOWN TO BELOW 4hz !! I actually think it has more TR in the single digits than the MA’s ! It actually lifts the whole back of the (heavy) plattform without me in the seat, LOL !

And the Viberry is a awsome tool for measuring TR, here is a video while watching a clip from The Meg :


I can’t seem to hold the phone steady enough, everything is shaking, LOL.

^^^ I guess I didn’t realize you removed your BOSS drivers in the process but sounds like it doesn’t matter and is now way better!! Ha, yeah, I bet those 4JBL2PR are just killin’ it like you say, sounds like you are in ULF WOBBLE heaven!!! And that powerful down that low, I bet that is just sooooooo super cool feeling!!! Bro, you just keep on raising the bar. …. just when you think your system’s TR can’t get any more INSANE, you take it up several more notches, I LOVE IT!!!!!!

I can only image how powerful that is cantilevered, as I got a taste of BK again today cantilevered, instead of right under me. This time with all 4 of them and with some different settings, so seemed to work way better than the last time I tried it. Whatever the difference was it worked, and man I couldn’t hardly believe what I felt. As we know though, the BKS are only good down to about 10-12hz. BUT, It was so strong feeling on what I demoed that it felt like it was hurting my insides LOL. I love this feel and always have, so I welcomed more of it than what I was getting (which I didn’t think I could get much more of). Will update when I get a chance and am pretty stoked about it. I don’t know that it’s a MASSIVE difference like your latest change, from what I had with them positioned under my but. Well maybe, it’s enough to shock me in the difference it made, so maybe it was massive hahaha

Yeah, i had "only" 12xJBL’s to play with, but it is pretty clear that this was a better solution
As i have said before, the TR Sleds are incredible sturdy and stiff, but they are starting to creak and make noise with these monsters now. And because of the weight of the VNF boxes, i only have 4 screws fastening them to the plattform, but i am starting to wonder if they have the capability to fly off the plattform, LOL !!
I would NEVER have believed that a couple of drivers could have so much force !

Another added benefit compared to the old sealed 12xJBL version, is there is now a ton more chest punch!! It seems basically just adding the 2 SLAPS pr box made the JBL’s themself much more effective! When sealed i ran 1 channel of NU6K pr box at 4 ohm, so a total of 1.5 NU6K. Now i run just one amp, with 6 pr channel at 6ohm, and it POUNDS compared to before! So tight, so punchy, and with the immense added heft and weight down low. VERY cool.

Here is a pic of the EQ i started with today for the VNF’s. This was using REW autoEQ, but i wasn’t happy with it, so i went at it manually

And the curve with all subs are much smoother down low now, than when i started.



Nice you hear you made improvements again Man, you change things around, LOL. I though you had found a good placement for the BK’s? Well, i can totally understand you liking them cantilevered, that would kind of be what i have, only kind of opposite. But having movement both from under you and behind the seat can be more effective. You with BOSS under you and BK’s cantilevered, and me with BK’s under me and JBL/PR/BOSS cantilevered. I bet the result is a lot of the same Awsome job, man, always fun when you can get a better result by just switching around the gear you already have So much fun finding these "gems".
This time i had to "invest" a bit in more SLAPS(still cheap, relatively speaking), but i gained in both sound and TR, so win-win

^^^^^ Awesome!!! Those things just sound BEASTLY!!! Great job on the FR too!!!

Yeah, the result is probably a lot of the same on ours, just kinda switched with the gear. LOL …. Well, I was really happy and loved the BKs under me in the position that I had settled on, better than behind me before. But long story short, to keep all 3 seats feeling pretty equal in intensity from the BKs, I needed the 4 spread out better, instead of 2 under my seat (I want at least 2 under or on the MLP seat), leaving only one under each outside seat. Plus, only one amp to drive them all and not allowing different levels that would be needed on the outside seats to feel equal. Doesn’t matter much I guess because its mainly me watching in the MLP but thought it may be an easy fix if I could get them to feel as good behind me. Plus, I thought 4 across the back could work better with one amp and all levels could be the same. I thought I’d at least try it since it’s a quick changeout and simply put, it worked like a charm this time with different settings etc. and turned out way better than I even hoped for. So, win win I’d say

I haven’t been wanting to mess with it because I’ve just been enjoying content like crazy and have been so pleased with the system, except for some creaks from the outside chairs at spirited levels with no one in them from so much TR (which this fixed as well). I’ll try to explain more in an update but got a wild hair today and just changed it out right quick to try it. This stuff is getting pretty easy to do at this point LOL.

Was absolutely thrilled with the results, so back to more content for a good while At least until I get another wild hair and try for a 24 behind me or something, or maybe mess with my MBM again at some point for a bit mote chest punch or something. Or maybe even the Slats for the rear 3 positions in the sub riser. May work, may not, IDK.

Actually, I was going to just move ALL MAS and ALL BKs to my seat only (since its mainly me in the HT room) first just to see how it would feel, but honestly, after trying it the way I did today with the BKs spread out for all seats cantilevered, it’s so potent feeling now (and in all 3 seats) I don’t think I really need any more TR (lol yeah right!! Hahaha). Nah seriously, it felt freaking crazy to me today, like bordering on absurd and I’m not even pushing any of them to their limit at my highest listening levels. In fact, I have to back the BKs off about 2 db when I go from my more moderate listening levels of -20mv to -12.5mv (about the loudest I listen these days), or it’s just too much, as crazy as that sounds and starts getting a bit out of balance since I don’t use DEQ to back it off a bit.

LOL, I may feel differently about it as I continue to watch more content and as always, more demo time which I love just as much as watching new stuff But its usually during demo time that I start getting crazy and analyzing everything and wanting more, so we’ll see hahaha. I’m kinda thinking at this point though, with the way I have my particular rig set up, maybe the only real/good way to improve it is by adding a 24 behind me for more ‘actually slam’ from particle velocity, or even the MBM added back in. So far in my previous attempts, I haven’t been able to get the MBM nearly as lethal feeling as it was in my last set up downstairs. That thing was beyond insane down there.

Anyway, sorry to spill all that in your thread, that wasn’t my intention, but once I started telling about it, couldn’t shut it down obviously . So much for long story short, should have saved it for my thread I guess LOL

@SBuger . So glad you could find some more oummph in your setup. After i have tried cantilever, it is defenitely a tool to consider when trying to optimize your setup, espesially when mixing more than one TR device. 4x BK’s equals 13 !! pounds of mass(pistons), and with the added leverage of mounted behind the seat(cantilever) it is a force to reckon with
With more than one device, the point is to balance it out, so cramming it all underneath the seat isn’t always the best.

I hear you one the «difference between seat" experience, but you at least have 3 seats, with a middle main MLP, meaning when you watch movies by yourself, the whole plattform is centered/balanced, side to side. I have just 2 seats, and when i watch alone, i can actually hear the opposite end of the plattform is lifting from the floor, LOL. I may need to put some weigth/dummy in the other seat for when i watch alone, HAHA.

Yeah, about a 24".... i really don’t think i need/ want any more SPL, because i think i am pissing of the neighbours plenty as it is now, and a 24" can’t be silenced, LOL. I remember coolrda saying that before the 24" he never had any issues with complaints, but only a couple of days after getting the 24", he heards from neighbours, so......

TR on the other hand doesn’t affect the neighbours

Yup, i have been able to watch lots of movies lately too, and it is so much fun, the other day i watched Gåten Ragnarok(norwegian movie)

https://www.amazon.com/Ragnarok-Blu-...588253&sr=8-11

This was one the DB bass list, and although i have seen it before, not with this crazy setup. And it was INSAAAANE! It was a lot better than i remembered, it upscaled exellent with Neural:X and had a incredible LFE/ULF track !
Recommended !


@dgrizzard : yes, one NU6K for all 12 JBL’s. With the box(size) i have now and number of driver/radiators i am getting plenty of excursion with 100W pr driver.
With these small sealed boxes i could pump 500W pr driver and not exceed Xmax, but with this "ported" design i reach the same Xmax with ~100W.
Here is a excursion graph with the 3 different options:
Sealed 4JBL= yellow, 500W pr driver.
2JBL1PR= Red, 125W
4JBL2PR= blue, 125W
Same box on all.



125W is actually really pushing it at 18 mm, but it’s just a sim A NU6K has realistically ~1200W pr channel at 4 ohm, so probably around ~900 at 6 ohm, so more than enough for 6 driver.

Thanks! I am probably going to try and consolidate my amplifiers instead of buying a new one. Currently already have 2 (for BOSS and rear surr), so I could probably just buy 1 bigger one and consolidate everything into that.

Ahhhh ….nice on the Raganarock!!! I haven’t seen it yet, but may have a copy of it in MKV on my hard drive somewhere. I’ll have to check. I remember folks on the old bass movies forum used to talk about how great it was for ULF.

Thanks man, yeah it was cool to get a little more oomph out of it. Even with them getting only 250 watts a piece with 4 on one amp now, vs about 1000watts with only 2. Doesn’t seem to matter, which kinda surprised me. I guess they don’t really need all that much to do their thing like they do.

As far as spreading out the TR devices when running a lot, yep I agree its probably best. And yeah, when you put it that way about the 12 pounds of pistons on the BKs moving with leverage mounted behind, paints a pretty good picture as to why they can do what they can do.

Yeah, the seats with no one in them can be a noise problem when TR starts getting crazy. I ended up connecting my 3 seats again, even though I got away from it there for a while to help cut way down on this. So, this combined with the BKs now in the back seemed to eliminate almost all of the bad noises. I just barely heard it yesterday on right seat.

Good Idea for some dummy weight in the other seat when watching alone. You’ve just got so much TR power now that it doesn’t surprise me that that’s happening on your unweighted seat. If it gets bad enough too, it can really be distracting. I started watching the new Godzilla the other day and I was getting way too much noise from the other seats and is partially what pushed me into making the change with BK position and connecting the seats again.

As far as the 24 goes, good point on the noise issues and pissing off the neighbors. Yeah, I remember cool saying that about this. That would not be good. So that could be a problem, didn’t really think of that Lol. It may not matter, but I’m not really wanting it for more SPL though, as I don’t even use all I have available now at my listening levels (at least I don’t think I do, but maybe on the ultra-deep ULF stuff). I just mainly want it for the internal hard hitting slam effect kind of like what Sekosche was talking about with his new 21 behind him. Kind of like single digit TR, I don’t know that one can ever have too much of that effect. It’s a different kind of TR/slam effect than what the other TR devices give. Well, at least on mine since I don’t have it connected to my platform like you do.

Just putting this post up here too, in case someone finds it interesting :

More testing ! This Qvibe thing is so much fun

So i taped the MPU to my speaker cones and let it rip
Like so:



So this basically measures excursion of the driver. Here is white noise and sine sweep with a flat signal. This is a SI18HT in a sealed box, so i guess it shouldn’ be a flat curve?



And here is on the JBL driver which is in the box with a passive radiator. White noise and sweep looks really similar actually.



And here is taped to the passive radiator in the same box. Not as peaky as the Winisd would suggest.



Same as above only with the EQ i need to correct FR. Bottom pic is MPU on plattform above the Crowsons, with and without EQ/LPF.



And i finished the evening with a viewing of San Andreas. WOW, what a ride! There was a cool wobble at around 1:32, so i whipped out the RPI AND the VS to measure it, and they actually show pretty similar too



PS: the Qvibe pic is up to 80hz, but if you look at 0-50hz, they are very similar.

So i went on the HDFury website to see if i could find something better, like a Vertex, or something.

Well, i ended up with a Vertex2, a even newer and more improved version than Vertex, and it only took 6 days from i ordered until i got it, all the way up in Norway. Man they ship fast!

And this beaty was on another level, so much more sturdy and it ouzzes quality, and the little OLED screen is really cool

This new one solved several problems.

First of all it worked flawless with my earlier idea about splitting UHD and 2D/3D BD(for including the Darbee and Mcable), same as i did with the Integral.

And it solved the Dolby Atmos MAT issue, where i couldn’t use my dual Atmos AVR’s on Netflix and ATV4K, as it somehow reverted to multichannel 7.1 as soon as i turned on AVR nr2. Not anymore, all sources work with full FrankenAtmos.

It has 3!! HDMI outputs, 2 for up to 4K full spec, and one for audio only full spec. So now instead of going through the Denon 8500 and via Zone2 HDMI to my second AVR, i simply use the third Vertex HDMI output to my second AVR for sound. Much smoother.

It has 4!! HDMI inputs, so now i connected all sources to the Vertex2 and then on to the Denon 8500. This way i can get full on-screen info about every source regarding 4K details.

And it switches automatically between the active inputs ! I am so impressed with this little gadget, it just simply works! And simplifies the use of my setup. Awsome
Gah, I haven't read this thread in awhile and missed a ton. It was interesting to see that you're using the Vertex2 now. I picked up one of the HDFury DIVAs back when they first launched and had been thinking of trying it to Frankenstein a bit. The DIVA is similar to the V2 but it also has an input lag sensor that you can run and it does active bias lighting. I mainly bought it for the latter with DreamScreen going out of business. I still have my old Denon 4310 laying around. So I was thinking of maybe hooking it up to the audio only HDMI and using it to run additional base layer channels. That way I can get wides and do a 9.1.6

I'm glad to see you've done some upgrades too because I'm coming for you. SLAPs were delivered today and I already have a couple stacks of subs piled up. The temps here are finally under 100 and my wood store is having their fall sale this weekend. I'm finally going to be able to get back to building some new stuff.

Yeah, i looked at the Diva and the rest, but the Vertex2 had what i needed and was cheaper, so.....

Only positillity for wides on the 4310 is the older obselete DSX, i would at least look for a newer model capable of NEO:X. Also remember if you mix in a pre-Atmos AVR into a Atmos setup, it will also contain the content for the overheads in its base layer. So for example your DSX wides would also have the front overhead content, making the pannings and direction dilluted.

Exciting about your upgrades Can’t wait to hear if you will like the SLAPS like i do PLEASE do make a thread/update your thread when you start

Yeah, the V2 is perfect for what you're doing. If I didn't want the bias lighting I would have gone with it too. What you mention with the 4310 is one of the concerns I've had with it. I had been thinking of it as proof of concept and if I end up sticking with it I might look into a cheap 2nd receiver.

Will do on the updates. I should unbox everything from their shipping boxes and start the update in my 24" build thread. I'll just use it for it. I'm going to be building everything to match too.

Yeah, i have the ambilight on my Philips Oled tv, so no need there, and i watch movies on the PJ with pitch black, so no need there either

You COULD do 7.1.6 with the 8500(as i assume you do now?), and get another 4310 and use the PLII trick to get wides, by extracting a center(wide) from each side’s front and surround

Or, use the 8500 in a 9.1.4 setup and use two 4310’s to extract two top middles

Yup, your 24" thread will do Will follow along eagerly

Hey Nalleh, are the JBLs covering the same range as your other subs or low passed differently?

Yes, they are low-passed differently. Because of the immense mid bass capability that 12 of these have i use both EQ and a LPF to tame them up top A 18dB LPF at 60hz(and negative High Shelf filters) is what i currently use. Using a too high LPF on nearfields, say above 80hz IMO can make then more localizable, and/or sound boomy. But this is preference and different for each setup, but 80hz is a good start point
