Hello Kim or other,
When pushing my 3065's (at least I think so) towards their uppermost limit, I can sometimes detect the faint smell of hot pc board. I believe it is not coming from my amp (sony HX1002) since no matter how loud I go, it never gets any warmer then a 115 to 120 degrees F. Heck my video card has hit 160!. As soon as I detect this smell I immediately lower the volume level. The only time I crank the volume is when driving down the freeway to be respectful of others, so locating the exact source is rather difficult to do. However, I suspect that the smell may be coming from the resistors getting hot in the crossovers that polk supplies with the DX's. Would pushing the crossovers as such cause the resistors to run hot. Common since tells me it should. Also, I use the amp in high pass mode, with the cut off freq. near 60 or 70 hz. so not to over stress the the mid/woofers. Is this wise to do. Or would it be better to lower the 62 hz position on my EQ. I understand that using crossovers with a 12 dB slope can cause an increase in the amount of current which will bypass the speaker at or near the crossover freq. The have the crossovers set to the 6 dB roll off possition. One more thing, with the crossover setting at or near 70 hz. also slightly increase the power handling capabilities of the speakers.
