My TR JOURNEY (PS: not covering the subs here, just the TR part of the setup)
My first TR "setup" i guess would be this back in -08 or -09 :
Some cheap POS Pyramid 12" in push-pull sealed boxes. Crap, but they did add some TR, which i hadn’t felt before.
Back then i didn’t have any REW or Minidsp, so AVR calib was all it was.
Then a couple years later i got some(also dirt cheap) shakers called Sinus Live bassPUMPs III, 2 pr
seat, and it was amazing!! These were actually incredible value for the money, and worked down below 20hz, they really shook the seat and was miles better than what i had felt before(little did i know, LOL).
Then in 2016 i found the Crowson thread in here, and just had to try it, and ordered 2 of them.
Holy cow this was on another level!! All the way down to single digits, WOW!!! This was a game changer! Back then i just ran them of a old AVR, and i was STILL flabbergasted! Within months i ordered 2 more, and a dedicated amp, and with 4 Crowsons i thought i was set for life regarding TR.
Later that year i also got a Behringer B1200D after finding the MBM thread. This was more of a midbass step, but being nearfield it added a lot of TR to the mix, but somehow i wasn’t happy with it.
I even tried with my PSA S3000i + the 1200D in NF setup but not good enough.
Then in 2018 i read the "cheap JBL 12" thread", and i found my new nearfield setup, ending up with 12 of them in sealed boxes right behind my couch for a Very Near Field setup. And it was AWSOME !!
guy kept advocating these Buttkickers !!! Since i had the "top of the line" Crowsons, and had read reviews complaining about the BK’s, i had no faith they could add anything, but i was curious, so i got 2 of them. After confirming the two biggest cons with them(the noise and bottoming out), i started to discover the pros about them. And fell in love ! Nothing else can do what they can, they are insane. So i got 2 more, LOL. I tested a couple of mounting positions before settling on having them under the front of the seats, with the Crowsons under the rear. I made a new plattform to mount all of it on, and had the best setup yet
Up until now i had run a pretty hairy house curve in my minidsp to compensate for the neutered LFE tracks Hollywood was putting out, but then the BEQ thread was born, making all tracks full bandwith, and once again came a game changer, it changed moviewatching from then on!
However BEQ and my house curve was to much, and i blew two of my Crowsons within half a year. So i had a choise: i could either get them repaired, turn the level down on them and continue with a reduced effect. NOT a option !
So i took a step forward by ordering 2 more Crowsons for a total of 6, and went for a stacked setup! I built a 2x3 stacked Crowson setup, and now i could turn down the level, use a more normal couse curve and STILL get a better result from the Crowsons.
And still with the BK’s under the front.
This was now a totally insane setup, and the stacked Crowsons, BK’s and JBL NF’s gave a mindblowing experience. I was very happy
Then Tim invented the BOSS.....
Using the same cheap JBL’s (as shakers)and some marvelously soft silicone isolators all mounted on a plywood sheet under the seats.
Again, i was skeptical and didn’t jump on i right away, but got curious again, so had to try it, so i robbed 1 of my JBL NF boxes of it’s 4 drivers and mounted them(push and pull to make them fit) in the plattform, under the couch.
But i didn’t like it, thought it was to wimpy, so i got 2x SI18" HT subs used, removed the drivers and mounted them under the couch for BOSS duty.
Didn’t like it, almost gave up on BOSS, but decided to try one more option: cantilever! Or behind the seat instead of under it.
By now my plattform was full of holes from all the experimenting, and i still had a lot of testing to do, so i got creative and came up with a new plattform to make mounting and testing all the different gear i wanted possible. It ended up being incredible stiff, was very flexible regarding placement options and made room for all the components i ever wanted to fit in there. Here is the prototype.
VOILA, that hit the spot, and i loved it
this got me fired up, but the heigth of the 18" meant that the VNF needed to be very high up to work, so instead of 1x18", i tried 4x12" JBL for cantilever BOSS, and that worked very well, and didn’t require the VNF’s to be so high. So the final version of the TR Sled looks like this.
In the middle of this testing i also tried a "combo VNF/BOSS box", which started from the idea i had about extending the LFE on the VNF boxes by using a passive radiator sub together with the JBL’s, and by mounting a Earthquake SLAPS M12 passive radiator in a downfiring config, the incredible stroke(4inch) and mass(500+grams) could be used for BOSS duty while the JBL’s facing forward took care of the FR and near field effect. Win-win.
So, with all components tried and tested, i could finish the whole thing and mount all the gear on the sled.
So this means that i have 4 !! different ways of making TR on this one patent: the TR Sled.
Per seat: 2xBK in front, 2x MA in the middle(2x2 stack on the left seat), 4x JBL cantilever BOSS and 2x JBL VNF box on top with SLAPS passive radiator downfiring for BOSS duty.
And since i have a two seat couch, that means double all that for the whole couch! The TR part of my setup is now waaay more complicated and expensive than my main sub section, LOL. Heck i have 4x NU6K’s just for the TR part alone, LOL(6 total for LFE).
But the result is just totally bonkers, and WAY better than i even dared dream of, so i am happy about that. Another advantage about optimizing TR is it doesn’t bother your neighbours, while getting more subs defenitely would
But still very stealthy
This got long, so i will leave "my thoughts" for another post, LOL.
