The issue with moving your sides down off the ceiling behind you is that they will probably end up too close to someone’s ears. Hi, Do you think its good configuration? A VOXX International CompanyCalifornia Supply Chain Transparency Disclosure, Click here to send an email to ProSystemDesign@klipsch.com, Two 1â Titanium tweeters in vertically stacked tractrix horns, Bass Reflex via 1.6â diameter port - Front Flush with Ceiling. Agree with all your points. Thanks Nyal. a 4″ driver vs. a 6.5″). Features an asymmetrical tweeter island for wide off-axis response, 1" aluminum dome tweeters w/tangerine waveguide and a 8" extended response bass driver. Though we attended the training session 1.5 years ago and have been working to the recommendations since. ceiling height on the viewing wall is 9ft 12 ft. The 2nd row were pointed away from the 1st row to provide better coverage to both rows. The issue with “constant directivity” designs (which aren’t really CD at all, as a very large part of the frequency range is not covered by the waveguide) is that dispersion is normally quite narrow and therefore it is hard to get really good coverage with them if you have multiple rows of seats and / or a low ceiling (e.g. The ceiling height is very low at 7’3″ since it’s a 70 year old home. Angling speakers significantly reduces the coverage requirements. I’ve been struggling with my Height Vs. ceiling set up. 1. the MTM design is generally a flawed concept due to off axis comb filtering between the two mid-woofers. I’ve placed them within the angles recommended by Dolby. Whats the most efficient way to get the best out of the 12 surrounds. Different ceiling heights (9’6″, 8’6″ and 7’6″). If you understand typical speaker dispersion profiles then you’ll know that very few speakers have such wide coverage. Tweeter down would basically make it like an inverted bookshelf, but also be hanging down from the ceiling further than a “side” angle which would be, obviously, like a bookshelf on its side (tweeter next to the woofer instead of above it), but wouldn’t hang down as far since it would be hanging from its long edge and not short edge of the speaker. I have been wondering about this for a while since every other diagram is for 1 row of seats only. if i use ceiling speakers on adjustable brackets mounted in the proper position 65 to 100 degrees of seating position, should they be aim-able left to right or front to back? The room is small but currently running front, Front wides ( hardly used) Surround, surround rears and here’s the issues,I’ve got 4 more speakers mounted in the front height and rear height positions but they are on swivel brackets and can be angled to the LP ( listener positions)I’ve programed as heights and just don’t get much out of them. 1. Has the CEDIA white paper on spatial audio layout been published yet? Differences in SPL due to some seats being closer / further away than others. The side surround polks are directly in line with the main listening position. With the speakers pointed straight the front Atmos ceiling speaker must have consistent coverage out to ~70 degrees off axis! I do not think a 1′ deep, 5′ wide soffit is something to really worry about, and you’d certainly not see much if any “boundary gain”. The main rule is that you need to place and select speakers so they provide adequate high frequency coverage at the important seats. Ideally you need to have the measured off axis dispersion data so you can see where any crossover related suckouts are located and then use this information to position the speaker appropriately.
