No it won't perform any magic like flattening it out at all volumes. The FiX has less x-over features (by a long shot). Running them both would definitely tighten things up with good baseline but I'm not convinced its worth the money or loss of real-estate. Bottom line, the deck isn't ideal but you'll get to a good enough space with the TwK to be happy.

Did you plan on buying both? Maybe I misunderstood.

 

 

So I'm confused as to why the FiX wouldn't flatten the signal out? I've used it before and could hear the difference. I did like you said and called them. They said what you said doesn't sound right. You can calibrate with the bike running or off to flatten the signal. I'm just telling you what they told me.

 

Hey Ron - the EQ-ing at one volume is not the same as another volume (we're not talking about off vs running). JL Audio is well aware of this concept. Volume curves are nothing new, most factory decks lower the bass as you up the volume and trim some of the vocal range so its not like AM radio talk show voices. So how would you account for that when you take a measurement at a single volume? You can't, at least not perfectly.

Bear in mind even aftermarket decks suffer from this problem, for example, the "Loudness" feature compensates for the reduced bass at lower volumes (for completely different reasons).

Best way is to adjust at the most common volume you listen to, say 75% total volume and just live with it. You can also make multiple presets on the JL, say one for mid volume and one for max volume. Look up their DRC-100 remote controller, its specifically designed for this purpose.

 

I get what your saying and I have that remote you are referring to as well as the 200 series for the TwK. I'm currently using the BT wireless remote with VX amp. I think maybe I misunderstood what you were saying then. The unit is supposed to be calibrated at 75% which does flatten it out at that listening level and most of the way throughout other volumes. I've used both FiXs, the 82 for the digital out, and thought they did a good job on cleaning up the sound produced by the stock HU.
