First post in the speaker forum, please be gentle!
I did some searching, and, I have come up somewhat short on my particular configuration.
I have a 500 watt 5.1 amp running two fronts [10" bass reflex three-way speakers from my old stereo from circa 1984] which works really, really well. There was some "stress" with the old speakers in the sub-50HZ range, borderline distortion for the really deep bass. Today, I picked up a JBL PB10 150 watt 10" sub. I wanted to add some "chest-pounding" LFE to my setup. I set the reciever to 100HZ cross-over, hopefully, to send the most demanding base to the sub. Well, no matter what I do, the fronts still output this and the sub never really comes into action. If I set the receiver to front "small" speakers, the sound is less pounding.
Admittably, when running a HZ sweep, the PB10 kicks in at around 40HZ where the three-ways begin to go silent, and shakes and rattles anything in the room, but, I really am not noticing the great heralded effect of having a sub-woofer. The 10" bass-reflex fronts rattle the room too.
My old stero speakers are rated at a frequency range of 20-20,000HZ.
How can I get the sub to handle the 50HZ and below and cut off this frequency to the fronts with only a 100HZ cross-over on the reciever?
I am new to this stuff, and I thought the sub was really gonna make a noticeable difference, but, it hasn't. Is it because my fronts have the same size driver?
I have tried the "haunting" and "U571" and I don't "hear" a $179.00 improvement over having a sub or not. I switched the phase switch and "upped" the level of the sub on the reciever and the sub.
