For those coming here to get details about the BOSS, those pictures and description start in Post 10 and there's a drawing and guidelines in Post 29.
Also, one member asked what I thought was a great question...."what's the difference between a BOSS and other sub-in-riser platforms we've seen before."
1. Open Baffle Design...no SPL to worry about integrating with your far-field subs. Set it and forget it.
2. Drivers mounted in horizontal arrangement....more efficient transfer of TR to the body than vertical arrangements
3. More excursion than buttkickers and maybe even more than tactile transducers....comparison testing coming soon.
4. More sensitive than buttkickers or tactile transducers.....only 80 watts needed per driver
5. Main volume levels can be kept low while still delivery respectable TR and the experience doesn't get lost with low MV
6. As MV approaches reference, the BOSS keeps responding in a natural way keeping in line the the far-field SPL increase
7. Low cost....it's only $90 for the 3 drivers plus a 4x8 sheet of 3/4" plywood for $35
8. The mini-riser BOSS can fit under any front row or living room chair/couch. It's only 1.75" tall!
Number 1 and 2 are the probably the biggest differences between the BOSS and more traditional subs in risers....being an open baffle design, means it's more efficient and doesn't take much power to reach max excursion. Open baffle also means the sound waves cancel and there's no SPL...perfect for integration with existing far-field subs without having to re-calibrate. The horizontal configuration means most of that excursion transfers directly to your body in an up-down motion which is how we feel ULF in the real world.
There's some videos of the BOSS's in action also in posts 72 and 73. After watching the videos, remember all that ULF and TR is in every seat and every row of our theater including our 3rd row bar...all for less than $250 and 80 watts per driver......incredible!
Wanted to share some pics of our 20 year old home theater and give back to our wonderful AVS community.
My apologies up front for my lack of a DSLR camera and resulting magazine perfect images. These pictures are from my trusty i-phone to help illustrate some design concepts and ideas despite the lack of lush colors, exquisite detail and sharp images.
After that disclaimer, if you’re still reading, I’m a long time lurker, seldom poster but daily AVS’er. We GC’d our house in 1998 with provisions for a 17’x30x’9’ dedicated home theater in the basement. Being in Louisiana, a basement is a luxury most don’t have and we’ve been making the most of it ever since the home completed in late ’98. We didn’t have any children when the house was built and now have three, ages 19, 15 and 13. The theater has provided many great memories so far for friends and family along the way.
When designing the house and theater space in the mid-90’s, internet was in its infancy without many of the readily available home theater design/construction resources available today. Most of my knowledge came from books and magazines from the day that sometimes featured articles on dedicated home theater spaces and some of the science behind room acoustics. Being a mechanical engineer with an understanding of physics, wave propagation, resonance frequencies, etc….I knew getting the room right from the start would pay dividends later in many ways.
The theater room was basically constructed with sound attenuation in mind using methods of the time….not even sure if clips, hat channel and green glue existed back then? The walls are 6” thick and constructed of staggered 2 x 4 studs spaced on 2’ centers to make for flexible and non-coupled walls to absorb the bass standing waves and minimize sound intrusion into adjacent living spaces in the basement. The ceiling drywall is hung from 2 x 8 rafters on 2’ centers for the same sound attenuating purpose and are decoupled from the floor joists for the main floor which are standard 2 x 12s’ on 12” centers to support the weight and span from the house above.
The floor wasn’t treated and is simply commercial grade carpet glued to the concrete slab. The projector is mounted to the 2 x 12 floor joists above so the projector wouldn’t vibrate during heavy bass activity.
There’s no stage and the riser in the back is 12” high and stuffed with pink fluffy.
When we built the house, we weren’t sure how long we would live in it. Once we started having kids, we stopped moving and this looks like it will be our forever home. Especially since we doubled down and also built the pool of our dreams about 10 years ago to accompany the theater of our dreams.
The pool, like our house, is nestled about 100 yards into the woods and is called our hideaway pool for obvious reasons. It was only appropriate to name the theater as such to follow standard “dedicated home theater build” etiquette.
