Post Subject: A playback for Restaurant Music?Posted by Romy the Cat on: 3/8/2013

Well, my experience indicates that if in the installation of this topology people chose to use 4th order crossovers then they play crappy pop music on their audio. To play pop music within playback and to have pop interests in music is certainly not a sin but it unfortunately makes many fine things about this topology not truly understandable or not utilizable. You truly do not need this topology to care the complexity of pop music.

Anyhow, about the bass system. First of all 35Hz is sufficiently low and if playback does honest 35Hz, not the 35Hz of noise, then it is more than enough. I do understand that you want to get a larger mouth area but I question if it even right objective. The larger mouth area make scene if you change mouth to throat ration but in your case pyramiding the bass bins together you do not change it. You will get some very minor gain from coupling the mouths together but in my view it not right aim. You do not need an extra 2-3dB as you multi-amp and you easy can have any amount of extra gain you need. However, the present of central-radiated LF source is very devastating for an imaging of this topology of loudspeakers. Also the coupling between the drivers of your horn is affected by the location of your LF. There are few other things that will not work properly but it is not the point. Instead of reading all of it you need (if the installation still stays) to move the bass bins in vertical position, 2 per side, one above another on right and left of the horns. Time-align them and observe the result. After you did it you need slightly to play with toeing the horns. You will understand what I mean when you heard it. BTW, you will also begin to hear the contribution from that parabolic glass window. If you were a good boy you will then drop the crossover on that 90Hz low pass to second order and to play Beethoven Op 131 but it might be too much to ask….
