JL Audio CR-1 Crossover

Hi. Not really, Ozzy. Partly because I have not done much with it and am not sophisticated. However, as long as I level matched the subs, set phase, ran DARO, there was nothing left fine enough for the damping control to "fix". In my measurements, there is no dip or peak that broad to correct without some compromise. The manual states to set it by ear by way of too lean or full at 80Hz. I have done that with just one decent bass guitar song, and it sounded fine (no revelatory moment of perfect integration ;) +/- 1, then worse beyond that.

I recently picked up a CR-1 to pair with two JL F110s along with my Magico Mini IIs. I think it’s a great unit and an essential part of any hi fi stereo setup, even if you’re running full range speakers. I personally think every system needs subwoofers. I’ve listened to top of the line Magico floorstanders that still lacked sub bass notes that my F 110s are capable of producing. And, if you’re using subs, you should be crossing over the high and low frequencies with an active crossover. My Magicos sound tighter, more articulate and open without having to dig deep into the lower registers. I also run my f110s in stereo mode. I know bass is supposed o be non-directional, but in rare instances where bass notes are coming from both channels, like for example Ole by John Coltrane where Art Davis and Reggie Workman both play bass at opposite sides of the soundstage, the bass does seem to localized to the channel the bassist is recorded on. Overall, I give high praise to the F110s for being easy to place in the room thanks to DARO and the CR 1 for saving my amp from having to work too hard producing bass notes on the Magicos where I don’t need them because the subs have it covered. 

Hey Ozzy,

I'm about to finally take on the CR-1 project based on our system set up being very similar. Might be hitting you up for some pointers along the way!

As I mentioned we have similar set ups in that I will also be using the HT passthrough and running my 2ch set up from my DAC/Preamp to my amps.  Are you also running your 2ch through a dedicated DAC/pre to the CR-1?

Thanks!

Mike

hubbman,

I had my Lumin X1 running direct to my tube amps. I now have the JL CR-1 Crossover in between calibrating my JL F-113 subs.

Basically, I set my subs based on their mic and calibration process, then with the CR-1 I used it to find the best crossover setting. I use the subs internal volume setting more than the CR-1 controls to balance the outputs.

Happy to help further if you need it.

Thanks Ozzy,

Should have the CR-1 today...
