In the yellow area is the part that the bass doesnt sound at all , when i move to the purple area the bass SUDDENLY HITS LIKE BANG! and in the red area is where the bass sounds the hardest !

CECAA850 Posted November 28, 2017 Share Posted November 28, 2017 The only real way to fix room issues that you're describing is with multiple subs. 1 Quote Link to comment Share on other sites More sharing options...
Alex95 Posted November 28, 2017 Author Share Posted November 28, 2017 The r115 supports wireless connection with the receiver . Then which place in this room could be the best place for the sub. OR for the second sub(but i dont prefer to get a second sub for now at least) Quote Link to comment Share on other sites More sharing options...
RoboKlipsch Posted November 28, 2017 Share Posted November 28, 2017 Google sub crawl and try it. This is a common issue 2 Quote Link to comment Share on other sites More sharing options...

This is a common issue Also try moving the sub forward from the corner to where your purple line begins and face it 1/4 turn from how it's placed now. It will be more near field and most likely not as boomy. You may have to play with the phase knob a bit. Bill Quote Link to comment Share on other sites More sharing options...

That way at least the main listening position will sound right. The room will have peaks and nulls, there's no way around it. Multiples will help. 2 Quote Link to comment Share on other sites More sharing options...
mark1101 Posted November 28, 2017 Share Posted November 28, 2017 This is a classic case. I agree with adding a second sub. Solves coverage issues with least amount of compromise and facilitates true stereo. I was never satisfied with single sub coverage in my systems and rooms over the years. I always run stereo subs now. 1 Quote Link to comment Share on other sites More sharing options...
derrickdj1 Posted November 28, 2017 Share Posted November 28, 2017 Multiple sub is the best solution. One in front and one in the back of the room. Also, are you other speakers set to small? Quote Link to comment Share on other sites More sharing options...
Alex95 Posted November 29, 2017 Author Share Posted November 29, 2017 I have set to small only the side speakers ! Should i place the subwoofer next to my bed in the left side? Quote Link to comment Share on other sites More sharing options...

All your speakers should be set to small. Can you put the subwoofer behind your couch and give it a try? Quote Link to comment Share on other sites More sharing options...

Google "sub crawl". It work and will save you time in moving it around the room. RoboKlipsch gave you good advice. If you don't want multiples then this is your next step. 1 Quote Link to comment Share on other sites More sharing options...

Alex95 Posted November 30, 2017 Author Share Posted November 30, 2017 Thank you for all your answers. Ill try sub crawl for the moment and i ll probably add a 2nd sub in the future . THANKS Quote Link to comment Share on other sites More sharing options...
Alex95 Posted December 1, 2017 Author Share Posted December 1, 2017 HELLO GUYS AGAIN ! O bought today a Klipsch WA-2 and placed the subwoofer at the back of my room left from my bed where the bass was at its fullest and unfortunately i had no results. I think buying a second subwoofer can be risky . Maybe my room just doesnt suppoport it. The funny thing is that i've tried to place the subwoofer wirelesly EVERYWHERE in the room and in all cases it was not detectable at the main position i want it to be ! !

Alex95 Posted December 1, 2017 Author Share Posted December 1, 2017 would i have results if i gave it a lift in a taller surface? Maybe the sound waves are just dissapearing in the sofa's surface and never reflect ! Any opinions on that? Quote Link to comment Share on other sites More sharing options...

JohnA Posted December 1, 2017 Share Posted December 1, 2017 The sub crawl is an interesting idea. Can't hurt, but moving the sub from one corner to the other on the same wall just flips the room as far as the sub is concerned. Move the sub to the open corner along the left wall and try that, or at least mid-wall along the straight, right wall. Two, or 4 subs WILL work, better and give more even coverage. I've done it. Your couches are invisible to long bass waves; they are not an issue. Placing 2 subs mid-wall is among the optimum solutions for even bass coverage. https://community.klipsch.com/applications/core/interface/file/attachment.php?id=127705 Subwoofers should not be elevated off the floor. The floor and walls are boundaries that reflect sound back into the room and boost bass output, vital for high performance. Quote Link to comment Share on other sites More sharing options...

Alex95 Posted December 2, 2017 Author Share Posted December 2, 2017 Ok . First of all have a nice day to all and thank you for cooperating with my problem. i 've made a picture with 6 occasions of different subwoofer positions in my room and the observations I,ve made with only my ears. Let's say : YELLOW: when i dont hear the bass ORANGE: when the bass is decent RED : when i felt my ears hurting Quote Link to comment Share on other sites More sharing options...
