Clean sweep from JL
#47
By forcing the woofer to roll off sounds above a certain point (~3k at 12dB/oct), and also roll off sounds below a certain point (75 at 12dB/oct), I have a woofer that is happily playing everything in the middle without distortion that I can hear.

Let me clarify when I said to dynamat the whole door. The doors of a GS are already quiet, and sealed well. All I meant is to dynamat the areas that are wide expanses of metal, which will resonate more with a better quality speaker bolted to them. Dynamat around the speaker so that it is completely sealed to the mounting surface, and then listen to the system. This should improve the quality of sound dramatically, especially in the lower range of the speaker's response.

UPDATE! After installing the clean sweep everything completely changed! It sounds impressive now! Now I can set my front speakers to 60 Hz on HP no problem! WOW! Bass still sounds clean when no distortion whatsoever! But for me that's just too much bass so I put it at 90 Hz. Although I thought I had a sound deadening problem at low frequencies (60-90hz). The factory signal to the speakers were causing them to distort. Which made the bass sound terrible making me think that it was a sound deadening problem. Now I get a nice punchy bass! After installing the cleansweep, which cleans out the signal, it sounds clean even at high volumes! After changing my RE-Audio sub DVC from series to parallel which becomes 2 ohms. With my upgraded amp from 2 channel @ 200W RMS @ 4 to a mono amp @ 300W RMS @ 2 ohms the bass comparison is like night and day! The beast has been unleashed! Overall I'm very impressed of the cleansweep and would recommend it. Now I need to find me a good equalizer and I'm a happy camper! Thanks to all that help! And Happy Thanksgiving to all!
