Post Subject: My troubles with direct radiatorsPosted by Saturntube on: 1/25/2010

I have been playing around with speakers for a long time, and things started snapping when I got into horns. I have a system right now with an upperbass horn from 140 hz turned form MDF up to around 700 hz, to another horn, and another and a super tweeter. Now for midbass I have 2 pcs 10" drivers per side only to go from say 150 hz down to 50-60 hz (this can be movable) crossing over to a 15" servo controlled subwoofer per side. This are nice aluminum 10" drivers set up in an independent beautifull sealed bass cabinet with good volume, it is made out of stainless steel reinforced pipe with several materials inside to effectively dampen the steel but keep a rigid environment. I completely hate them! When I try to adjust volume or freq of the high pass xover I listen to deep female voices, strangely so, and this horrid woofers make a terrible resonance like they have a huge chest, so when I finally get rid of the chest resonance the midbass is completely gone, no chest pounding bass, no kick drum, and male voices sound thin, I try to cut the lower end of the drivers and raise the subwoofer up to say 70-80hz and this helps a bit but it is still midbass shy, as soon as i touch the volume knob on the horrid midbass drivers that resonance starts again... A friend said, easy solution, get a remote volume control just for those drivers and you can lower or raise the volume depending on the CD you are playing, or well the song you are playing, well really the part of the song...... IMO the problem is this drivers are too slow for the complementing horns in the system, if I were to cross over to a mid range driver or a ubicuos tweeter crossed at 2khz the woofers would sound just fine! but my system would be crap!I am now experimenting with bigger faster drivers and even tapped horn designs, but the cabinets are not so nice!So this thread of a huge midbass horn is, at least for me, a way to show me how much of a wimp I am that I still dont have a house breaking midbass horn!
