If you play guitar than do you know that you might affect harmonics of your upperbass by placing your guitar between your listening spot and loudspeaker? A guitar is a very powerful Helmholtz resonator and in addition guitar with its very think wall is a wonderful resonator. From some perspective a pair of guitar might be used a narrow band injection channel. It will not add colors as my injection channel doe but it might slightly change harmonics and softens of your upperbass. If you use sealed direct radiators for your upperbass and contemporary no-tone, concrete drivers then you might like some inflection of mild “port noise” that might give to some feeling of desirable softness without trashing your garbage drivers. I properly positioned and properly turned guitar might do juts that. Rgs, Romy the Cat "I wish I could score everything for horns." - Richard Wagner.

I do not understand what to make of my experiment. I do not notice difference to upper bass but in the mass strings higher up, there are less holes in the sound if i may, more of a cluster of instruments.   And stop telling me my drivers are crap, they cost me a fortune! No now i notice it, wiout guitar resonators the midbass is too thick, not right dynamic with rest of orchestra. Interesting. R weissman
