I'm hoping some expert out there can give me a hand with this.
I have a "low end" Pioneer D309 receiver in a home theater setup and I was doing some testing with low frequency test tones and the crossover setting. To my surprise, or my dismay, this doesn't seem to work. I set all my speakers to small, have the subwoofer connected via the receivers subwoofer out RCA jack to it's line in jack and do not have the front speakers "daisy-chained" through the subwoofer (which is the Sony I've mentioned in a previous thread). So, I went in and set the crossover to 150 hz (the Pioneer allows settings of 100, 150, and 200) and then went into Avia and did the low frequency left front sweep. To my surprise, the tone continue to come out of the left front speaker well after 150 hz. In fact, it continued to come out of the left front all the way till it dropped off at 70 hz which is the left fronts minimum range. At the same time it was also coming out of the subwoofer and continued to come out of the subwoofer down to its lowest point - 39 hz. I then powered the subwoofer off and redid the test. I clearly heard the tone coming from the left front and my Radio Shack soundmeter verified this...all the way down to 70-80 hz or so. I then decided to power up the subwoofer, disconnect the left front speaker and do the test again. This time I lowered the crossover to 100 and then did the test sweep. Amazingly enough, the subwoofer played the entire sweep from 200 hz down to 40 hz until it then dropped off. This makes no sense to me. Should not the crossover setting tell the receiver to only begin sending frequencies to the subwoofer when they hit ~100.
Does anyone know what the heck is going on?
Am I doing something wrong?
Is the receiver broken?
Or is the receiver simply so low end that the crossover frequency is simply a marketing gimmick and doesn't work or works extremely poorly?
Should I junk this receiver and look to invest in a better low end receiver, perhaps the Onkyo494 or other receiver that comes in around $300.
Help!
thanks,
