I have a Pioneer VSX-D510 receiver. As you probably know it is entry-level. Now, I plan on purchasing Paradigm Titan speakers for fronts. I believe the Titans have capable bass handling but they may not do the low stuff really well. So this is how I plan on setting up my receiver. I have a Kenwood CRS-159 center/surround speaker set(not great, but better than most HTIB speakers and I got 'em for only $100 Canadian unused). I would plan on setting the surrounds and center as small(they only have a single 4inch and dual 4inch drivers respectively). I would set the Paradigms as large. The receiver has crossovers of 100,150 and 200 hz. I think the best choice would be 100hz because I notice if it is higher I can localize the subwoofer easily. So I guess my real question is should the Paradigms be set as large. I could put the subwoofer setting to PLUS which sends stereo bass to the sub as well as the mains, which would re-enforce the bass right? Or would I be better of by setting the Titans as small and sending all bass to the sub? Now my other question. Many have told me that a higher end receiver even with a lower power rating will actually have more clean power. I find that I watch most movies at -25dB and most music at -40 or -45dB(-30dB or -40 dB in surrouund). The sound is very clean and powerful in my small room. I don't notice any distortion until I turn the volume past -10dB, I only did this once and never will again. It was quite loud and I'm sure it would have damaged my hearing if I kept it there.Does this mean I would probably not benefit from a more powerful receiver?
