no i mean songs that only have vocals for 20-30 seconds then just bass i could prob make it on Audacity just add test tones with a stripped song. My set up is DD3515 in a 5.5 cubic foot tuned to 32 hertz. it has around 1200 watts rms running to it. Its in a S10, i think it peaked at around 36 hz when i get it metered but i have tweeked and modified the box with supports sense i have been to get it metered. the alignment of the sub is port up sub up. Not sure what you mean by where it sounds best at. It sounds best when i have one door open windows up.
