To sum this mess up,
This is AVS forum so instead of ear buds and plastic speakers--put it to a standard and go.
Since I don't have Bose products, maybe the Bose fans out there can provide a clue on the proper Bose products to use to achieve 105 dB at the seated position? What model of subwoofer (bass module) would give correct response at 20Hz and below? How many bass boxes are required? Suggested room placement options? Any issues firing the Bose speakers through a movie screen? Solutions to those problems?
Do the jewel speakers work best with both boxes on axis? 45, 90, 180 degrees off-axis and what angles should be used for 5 channel VS 7 channel VS 9 channel etc? Do you find with your Atmos systems that the cubes work best flush mounted in the ceiling, run on brackets or does the bounce type Atmos enabled work best for the cubes?
In reality, it won't meet reference standards of 105 dB at seated position--but how close does it get? -5dB down? -10dB down? Can other subwoofers be used with the Bose system to improve low end response? If so, what alignment works best to mesh with the bass modules? Would you suggest running large subwoofers at 40Hz and below and crossing the modules at that point? What settings on parametric EQ's work well with the cube speakers when used as mains, center channels or surrounds?
Where are the threads "I have a Bose system and added Brand X subwoofer and here are the results" How about "Swapped the Bose drivers in my cubes for Brand X" full ranges to increase SPL and sound quality" Always wondered why some Bose fans have not posted "Modeled/tested the Bose cubes and made new cabinets with these results"
Speakers, as with most everything is built to a price point. Part of the hobby is to make what you have better by upgrading the compromises in the stock system. My Logitech 5.1 system was cannon fodder for my boys to destroy while I packed up my home theater and put it in storage. There is NO speaker that can handle 12 year old boys that know how to turn amplifiers on.
5 years later and only one blown speaker (and blown amplifiers) I did a search, found the specs, built some di-pole surrounds with "helper tweeters" with eight of those 3" full ranges and plywood. The braced 1/2" plywood with 1" baffles sealed and stuffedreally cleaned up the sound compared to the stock little plastic boxes. Since they are off-axis being 120 degree dipoles--I added helper or supertweeters to each side of the box to get the highs to measure properly.
Maybe the folks with the cube speakers have that option? Bill made a better 901 with Fostex speakers decades ago, I've always wondered what modifications made to the cube speakers worked well. The standard frequency response specs of 280Hz to 13,300 Hz +/- 10.5 dB at 85.1 dB 1w/1m can be improved. Any polyfill or coatings for the inside of the plastic boxes to improve the sound quality?
So what works best with Bose? The only tweak I ever did with one (besides replacing blown drivers) is to pitch the cubes and use bookshelf speakers with the bass module. The owner preferred that over building new cabinets, adding additional drivers etc. since the bass module output was not worth the effort. Somebody has to have the results of room correction EQ on their AVRs...time to fess up!
