That would be awesome if you wouldn't mind grabbing a couple pics so I can see the way you have the MA positioned/installed right now as you mention you are very happy with your current positioning. That would be incredibly helpful as it looks to me that your seating is similar framework to mine and would give me a great place to start.
Thanks in advance for any help!
Room looks great BTW! Jealous of those NF SW!
No prob! Glad it helped!!
Well, as far as the seating shifting around, not really at all, except may a little over time on the left seat (that only has one arm) that just butts up to the two arm seat IF I don't connect it to the 2 arm chair. I just use a clamp (clamped down really tight and works great, probably a better way but this is quick and easy) to connect them together. They are pretty heavy seats too (probably like yours) so they don't move to easily actually. Like connected, the two seats are more like one and the 2 MAs and 2 BKs under each seat (plus the VNF's behind each) effect both seats as well, at least somewhat. What is primarily under each seat with the MA's and BK's still primarily effect that seat though, and same with the VNF's behind that particular seat if that makes sense. It all helps and adds up though, but still ...
Also I just leave my seats in recline mode at all times and just unplug them, killing the lights in the armrests. They are distracting in a blacked out room when watching a movie. That and I have them exactly where I want them (about an a half inch from full recline). I'm probably the only one on AVS that does this, buy hey it works great and I really have no need to every sit them up straight, as this is how I watch movies and is just as easy to climb into it in the relined position
This puts the seat back exactly where I want it in relation to the driver from the sub, about a 1/2" away here at the top edge of the sub, and about an inch away from the bottom bar brace of the seat that goes all the way across at the bottom of the seat.
Yeah I think our seats are pretty similar, so might work great on yours as well.
Here's a few pics I snagged for you that may help give a better idea ...
I pulled the 18" sub back to try to show you what's going on underneath the best I could ..
If you look closely, the MA's are under the little plastic feet on the inner framing of the chair, keeping the MAs from touching directly to the metal frame. Plywood would work too if you don't have the plastic feet in the right spot...
And then a shot form down under along the floor for another angle. It also shows the driver of the sub about an inch away from the support bar on the back of the chair down low. It looks closer than 1", but the camera just makes it look like that. This is critical though for it to not be too close and allow excursion of the driver on heavy ULF scenes but still be close enough to get the FULL benefit and effect of a Very Near Field sub.
Here is how I have the front as well that might give you an idea on how I leveled it up and used the isolators. I used big washers to get more heght to match the MA's, plus the isolator feet on top of a piece of cut plywood ...
And one with the seats clamped together to make them more like one ..
Thanks for the comments on the room!! I've put a lot of work into it to get it like I want it for darkness and setup of everything. Its dark and small, but does just what I wanted it to do, which is fully immerse me in video, bass (Impact and TR), as well as the surround sound with Atmos etc.
And about the NF subs, ya know what. I wouldn't trade them for anything or never want to be without them. I'd even take them over the MAs for a lot of reasons if I had to choose between them or the MA's. They are that capable down into the singles for TR, plus bring the weight, fullness, pressure and midbass slam to get with it. Luckily I don't have to choose and can use both, and they combine wonderfully to bring it that much harder, while still feeling like its coming from the subs, or better yet from what going on bass wise on screen for real in the room (not localized).
If you can add some VNF subs behind you eventually in addition to your MAs, highly recommended if you like a lot of Impact as well as a lot of TR
Hope this can help a little more! There is also one link that I wanted to link to about the positioning of the MA's that I used like Coolrda did. When I get a chance this afternoon, I'll find it and come back and edit this post to include it. EDIT: Ok here is that link to show what it looks like under the seats for another view that may help as well. Coolrda's seats are just like mine (HT Design Pembrokes) and may be real similar to yours underneath as well. He ended up liking the MA's way better positioned on the insides (blue markers, not the red) vs under the armrests. And I totally agree after trying them both ways. A large piece of plywood underneath may work great to cover all seats as well, but if you don't want to do this and want to do it like we did, it works great, especially with two MA's per seat.
