If it wasn't for Audio Control car Audio wouldn't sound as good
Crutchfield Customer Review (What's this?)
I purchased a Pioneer AVH-X5800BHS from Crutchfield for the network mode active crossover ability to run some Focal PS165 6.5" woofers and Peerless NE25VTS-04 1" Silk Dome Tweeters, which are superior to the Focal aluminum tweeters. I couldn't get the gains set right on the 4 channel amplifier feeding the tweeters and woofers and things just didn't sound right no matter what I tried. I have had a lot of experience with Audio Control equipment including their LC2i, DQ61, EQX, and now this fantastic 2XS. The quality of their products is fantastic! The Pioneer head unit in network mode is capable of crossover slopes from 6 db/octave to 24 db/octave and the points are fully adjustable. Comparing this 2XS to the Pioneer set at 18 db/octave at about the same crossover point (4k Pioneer vs 3.6k 2XS) there is a noticeable difference in SQ, which is partly or all attributable to the line driver portion of this unit. Tweeters went from sounding harsh in the upper vocals to absolutely beautiful sounding. This thing made a very noticeable difference in SQ and now I can run the Pioneer HU in standard mode so I have my fade and other features back that you lose when in network mode. Why some people purchase passive crossovers for a couple hundred when they can have an active crossover that is fully adjustable for half that boggles my mind. With active crossovers you don't need as much amplifier power and the signal to the speaker is as pure as it can get so long as you are using good speaker wire
Pros: Superior sound quality, smaller than many active crossovers, line driver and subsonic filter, can minimize gains on amplifiers for lowest possible noise floor, cheaper than some passive crossovers, less powerful amplifiers are needed because the filtering is done before the amplifier instead of after. Note: I ordered this same thing from Sonix and then later ordered another one from Crutchfield two days later and I now have my Crutchfield order but not the Sonix one yet. Crutchfield is the best!
Cons: You will need more amplifiers compared to using a passive crossover. switching resisters to change crossover points may intimidate novices but then again active crossovers are for serious audiophiles.
