I have a complete DX system. I have been playing with them for about 8 months. I just recently bought the DX 12's for the 2 component sets. and for some reason i cannot get everything to balance out. The front speakers are way too brite, and the rear speakers arent loud enough! and the bass doesnt blend in well at all. i took it to a shop here is town and they said everything was hooked up properly. ive check the phase several times in each speaker and tried to invert phase on everything. ive also tried many different configurations on my 3 band EQ and nothing seems to balance it out right. everything has the same cross over frequency. Ive spent a lot of money on my car and this is very disappointing and its starting to get very frusterating. Is there anything else i can do? any unique thing that i could try at all that might make my system better? Im currently runing 40 X4 and 120X2, if that helps any... thanks for any info you are able to give me

Have you checked the position of the tweeter attenuation switch that is on the crossover? It maybe set to the +3dB position. Try setting it to the -3dB position. This will reduce the output level of the tweeters plus this is helpful when the the tweeters are located near any hard reflective surfaces such the door windows, windshield, or any hard plastic panels. If they are are still too bright and there is more than 24 to 30 inches of distance between the midbass driver and the tweeter, then invert the phase of the tweeters. You may need to do all of the above to correct the problem.
Not enough bass?? First of all are you using a crossover that uses a 12 or 12 dB per octave slope?? If so invert the phase of the front speakers and give the system a listen without the subs
active in the circuit. The bass should improve. Next we have to get the woofers in phase acoustically with the front and rear speakers. They can be wired correctly but out of phase acoustically due to the vehicle's transfer function, location of the speakers, and the rate of the slope used in the active crossovers. To correct the "Lack of bass" problem simply invert the phase or polarity on both woofers. This is a very common problem and it just takes a little effort and critical listening to correct it. If you are still having problems or this seems confusing, give us a call at 800-377-7655 between the hours of 9 AM to 6 PM Eastern time and we will be glad to help.

Thanks,
