But, even though it will play the Hulk punch scene, the Crowsons manage that better. However, the combo of the two is outrageous and an absolute blast. The Pod scene from War of the Worlds was crazy. Also, the THX Amaze and FotP barrel roll just have a presence they didn’t have before. And, I can finally play the JW club scene and get some punch behind his gun shots.
Now I’m debating connecting them. If is do, it would be easier to add the pieces to the top vs taking everything apart to add them to the bottom. Does it matter?? Also, I am unable to tell how much clearance the driver had. Each platform is sitting on 6 or more ISOs. But, the chair on the MLP platform is heavy. And, I can definitely see it sits a little lower than the other 2 recliners. I’m thinking of adding spacers under the ISO’s to get a little more height. This also might make connecting them an issue.
Thoughts on this. Anyone pushing more than 80 watts?
Hey Rowan.....Thanks for the update. I forget, but I think you're running the JBL's...correct? If so, each should take about 80 watts. If you have a 3 JBL BOSS platform, it will take a total of 240 watts (80 watts x 3). Other members have reported pushing as much as 120-130 watts into each JBL and also using DSP to increase the single digit response of the JBL's. These little guys will take quite a beating so don't be afraid to push them too hard. Just don't try single frequency test tones. One member fried his JBL's in a sealed box arrangement recently using a single frequency test tone and running it for a couple minutes fine tuning.
It's better to use your favorite demo scene like you have been doing to find the limits. Once you've found the limit on that demo scene, play a couple more favorite demo scenes to make sure everything behaves OK.
When you say you're debating connecting them.....I'm not sure what you're connecting. If you're talking about integrating the Crowson's with the BOSS platform, I think most have found the Crowsons on top of the platform work better than below the platform, but I think
is currently experimenting with both on-top and below the platform and also with different isolator placements with the Crowsons, so the jury may still be out.
Regarding adding more isolators to reduce platform bending...yes, definitely add more isolators wherever you see the platform bending. Any bending of the platform will take energy away from your butt which isn't a good thing.
Hope this helps.
Edit --- I think I remember you had a splayed front row with 3 separate platforms if I remember correctly.....if so, you may mean connecting each of your 3 smaller platforms to make one big one. That will improve your BOSS experience but the connections have to be very rigid so the pieced-together platform will move all as one piece. I think when Chris Young did his pieced-together platform, he used metal plates on both the top and bottom of the platform to strengthen the joint. If the joint is strong and the platform moves all as one piece, then the isolator placement guidelines in post 29 can be used (one under each chair leg, plus anywhere there is more than a 2' gap).
