Amazing new bass contour control


Remember the 2 Delta 15's in 4648 thing I did last month? Well I had some more precious time to waste so....I took it away from the Home Theatre and wired the outputs of Ella to the cheapass 100 watt P.E. plate amp an then on to the speakers. You know, high level in-high level out.
I learned 2 things:
1. Having the plate amp with it's crossover 'tween a good source and good speakers creates a very audible difference in sound. Most, but not all of which I liked.
2. Increasing the level of bass below 60 Hz while taking the load off the main amp and speakers is really, well, fascinating. JBL 2226's augmented by the 2 Deltas may not go below 40 Hz flat but, as Linda Fiorentino said in MenInBlack -"there is something going on down there."

Such an amazing change in character to a system I listen to daily creates a strong argument for the old Julian Hirsch school of audio: frequency response is everything.
That begs the question: is my next big "improvement" another set of Deltas in a second 4648 box or a $49 equaliser?
