just rad about speaker spikes, is it really improved sound quality,? and should i put spikes on my prosub 600?

Hello Watt, when you say the output level is set to zero, do you mean the output to the subwoofer in your Denon receiver? It sounds like you may not be getting enough level to the sub, plain and simple. Try experimenting with that and let us know how it turns out. Best regards, Joe

Hello Z, carpet spikes can help anchor a subwoofer. You might contact Chet at info@definitivetech.com or 800-228-7148 if you want to try them. Let us know if you hear much difference with your sub, OK? Best, Joe

I had a question for you guys with more experience on this subject. I have 4 promonitors, a procenter 2000 and a prosub 1000 waiting to be installed. These will be run off a Pioneer Elite VSX-70 (2013 Model). Everything is still in the box. This is my 30th bday present from my wife so I am under strict orders not to touch it until my birthday three weeks from now. Also included was a new 55" Sony LED TV. Anyway I've been reading up on this set up and see that the recommended crossover setting for the promonitors is 80hz and 60hz for the procenter 2000. What I didn't realize until a few days ago is that the Pioneer uses one crossover setting for all speakers. So would I set the crossover on the pioneer to 80hz or 60hz? I assume it would be 80 but if I set it to that am I losing anything from the center?

Sorry if this was already asked but I didn't see it answered. Thanks!

Hi Dan, I'd suggest using 80 Hz. You'll still have a great sounding center channel speaker, and your ProMonitors will sound great there too. Sure, the PC 2000 can go a little lower, but remember that crossover points are not brick-wall filters, so there will be some sound below the crossover frequency. Your setup will sound great. Let us know after your birthday OK? Best, Joe

Dan, just as Joe says. You might even try the 100Hz crossover for all speakers, just for comparison. Choosing a crossover frequency can be a subjective matter, especially as room acoustics and speaker placement play such a large role in determining system response. The major tradeoffs: a higher crossover takes more load off the AVR's amplifiers, effectively making it more powerful. But a higher crossover also puts more mid-bass into the subwoofer, making it easier to localize and possibly disrupting the seamless blending of the speakers and the sub. Only your ears and preferences can decide if there's a meaningful difference.

As for the center, even if you could separately set the center speaker to a 60Hz crossover, 99% of the time you wouldn't notice a difference -- and half the time you did, you wouldn't be sure if it was better or worse.

Pioneer's choice to use a common crossover for all speakers is done for a reason, one that has to do with eliminating the possibility that carving up the bass into too many small segments and distributing them willy-nilly to a bunch of different speakers will cause low-frequency interference artifacts. The system you've purchased is ideal for use with Pioneer's MCACC room-correction system, since four PM1000 and a PC2000 are as close to a perfect match as you're going to find short of five identical speakers. Using the same crossover for all five of them will only help enhance that perfection.
