I know, I know every post I read says to push the subs crossover all the way up and use the crossover on the receiver, but I read a review by Brian Florian of the Paradigm Cinema Series over on Secrets. Although I don't have these speakers, I have similar smaller bookshelf speaks/larger sats that would be benefited by a 100 Hz crossover.
Here is the part of the review I am interested in feedback on.
"The only "issue" is that the system needs a relatively high crossover between satellite and subwoofer. 100 Hz would be good. I certainly would not want it any lower than the 90 Hz crossover in the Yamaha receiver we used for most of the listening tests.
A high crossover in and of itself is not a "bad" thing, but it does bring two stipulations: A) The subwoofer really must go in the front of the room (which is generally preferred anyway), and B) Extra special care must be taken when adjusting the splice between sub and satellite. It was unusually easy to get subjectively bad performance from the system, resulting in a very fat, bloated sound. Run the sub too lean, and the cinema set will have a hollow, empty character. Run the sub hot and you'll have irritating one-note bass.
With 99.9% of surround sound processors these days providing their own high-pass / low-pass combination, I recommend starting with the PDR-10's own low pass dialed to the max and calibrate its level with AVIA. With the sub in the a-typical room corner, the bass will likely sound fat if the crossover is high (which it should be for these speakers). LEAVE the level there! By ear, bring the subwoofer's low pass down until the sound smoothes out. If you have to go much below the SSPs low pass, recalibrate the level and continue to adjust the low pass. Yes, the two filters (one in your SSP, one on the Sub) will interact, bringing phase issues to the table, but it is better to adjust this way than ride a subwoofer level knob all day."
Similar to what the review says, I get a bit of boom in the sub at 100Hz vs. 80 Hz. I tried what Brian suggested, and sure enough when I set the crossover on the receiver at 100Hz and start to inch down the crossover on the sub past 100Hz things really tighten up. 90 Hz sounds the best.
Could it be possible that this is the best setup for my system? I know that crossovers aren't a brick wall, so the hole I am creating may not be an absolute hole. Do you think I am better off just choosing between 80 and 100 on the receiver and not messing with the crossover on the sub?
Thanks
Greg
