This year I went from a BenQ HT2050 that was directly over the MLP in the room to the JVC, which I was able to add by building the port hole and mounting the JVC in the utility room from the joists. Let me tell ya, the look on my wife’s face was priceless when she came home to find the monster of a projector and me cutting through drywall to build the port with no warning.
And I’m not done ... the riser and bass upgrade is 2020. One more question for now.
I have a 10” gap behind the sofa due to the floating shelf. Instead of a riser, would an open subwoofer box running behind the couch give me adequate TR? It’s unused space and would be hidden from view. But I’d want it to rumble the sofa.. not the wall.
JonnyVee....Thanks for the details about your setup. I bet having the JVC in another room has made a big difference in your noise floor. I laughed when I read your description of your wife's reaction to the "slight house modification". I've been there a few times too!
The open baffle box behind the couch will only provide TR if it's attached to your couch. Once attached to your couch, you'll probably find the TR to be too much and quite distracting because it will simply be vibrating instead of providing pressure against your body like we feel TR in the real world.
The only way to get this pressure from a BOSS is for your body to provide that pressure when you're sitting or reclined against the seat.
Then, the BOSS just simply vibrates that pressure to make it feel so natural and powerful. That's basically all the BOSS is doing...vibrating pressure on our butts, backs, legs, whatever we're sitting on to make it feel natural. Without pressure, the BOSS won't feel natural.
The good news is, once we sit down, our bodies provide the pressure for the BOSS to work with. With the BOSS behind your couch, the only way to get pressure is to push your back into the couch back. Then, it will start to feel natural and powerful, but will get tiring fast.
I'd start with the BOSS first to deliver single frequency response and natural feeling TR when you're sitting upright on your couch. It will bring your movies to life and feel like you're inside the movie. You won't believe how much more the BOSS will bring to your current setup.
Then, if you feel you still want more chest-slam from behind, since you can't recline, you could take one or more of your existing far field subs and start experimenting with them behind your couch. I could never get the nearfield experience to feel natural for any given volume level or for any seating position. They didn't meet my goals for me and my family.
Based on your nearfield experiments with your current subwoofers, you can start to get an idea what you like and don't like and whether they will meet your needs and the needs of your family/guests.
The good news about your BOSS, when built to the prescribed guidelines in Post 29, it will provide a consistent and powerful experience to anyone who sits on your furniture and won't depend on seating positions and main volume levels. It will feel natural at any volume level and on any seat of the couch.
Hope some of this feedback helps.
