jmarshak,
I am crossing over at 80Hz. But still experimenting. Why did you choose 90Hz.?

Thanks erik. I’m thinking the reason there is so much more "low bass" is because I was drawing the bass out of the speaker outputs. Now I am getting the bass directly from the source in this case my Lumin X1.

My source is a High Rez Download.
I like "the stop the waves in the pool" comments, I would think mine would create some white caps!.

Thank you so much for the comments. I am really surprised in the difference between line level and speaker level low bass response.
jmarshak,
What crossover frequency are using with your JL subs and crossover?

gita,
Never thought about an intergrated amp with the CR-1. Seems like there should be a way to make it work.
ozzy

gita, Perhaps contact JL Audio for suggestions?
ohlala, If this helps:
I started with my subs close to the back corners, then I used the DARO. After that I tried to blend their output with my main speakers. Then I used the CR-1 to blend everything together.
But, I too am still experimenting with all the other settings. I can say though that just 2 days with the CR-1 and I am pretty happy with the bass intergration.
BTW, I also have 4-ASC 20" tube traps in all 4 corners.

ohlala,
Thanks for that info.
With my 4 F-113’s I am using left-right stereo configuration and then connected the same L-R to the rear subs. With all set as Master. This allows the ability to set the DARO individually.

Yes that is also my concern since previously I was sending the signal direct from Lumin X1 directly to my amps thus bypassing a preamp and all the associated cabling.
Now with the CR-1 I have again additional electronics and cabling in the chain.
But, so far I am having a hard time determing if there is in fact a reduction in transparancy.

For those of you who do own a CR-1 and want to use it with your home theater. The directions are incorrect. If you connect a RCA sub input from the Home theater into the "Managed Subs" input on the CR-1 you must output using the same type of output (RCA) to your subs. The same goes for XLR input.
I actually used a XLR/RCA adapter into the "Managed Subs" input so that I could still use the XLR subwoofer outputs.
I hope I explained this correctly.

Just a quick update:
The CR-1 is working excellent! I cannot tell the difference between running the Lumin X1 direct to my amps or running it through the CR-1. It is that transparent.
Highly recommended.

Thanks prof,
I am really surprised at how transparent the CR-1 is. I guess the main speakers used and the crossover point chosen is the challenge to making it shine. The CR-1 allows easy movement of that point for a seamless transition.

jmarshak,
I am only using the balanced inputs/outputs, so I leave it as grounded. There is absolutely no noise.
ohlala,
I have used the mono mode for my home theater pass through but otherwise its always in stereo. I have yet to play with the damping controls, any suggestions?

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.

hubbman,
Now that is strange because I am doing the same thing. I am using Cardas XLR/RCA adapters converting the balanced XLR from my Oppo 205 to a RCA input at the CR-1, while using all the other as balanced.
You may be creating a ground loop, have you tried lifting the ground switch on the back?
So, try just using the XLR output and convert it to RCA at the CR-1 and use them in the RCA managed inputs.
I will double check my connections to make sure what I am saying is correct.

hubbman,
I’m sorry I stated it wrong. I am using the mono sub output from my Oppo to a y- adapter then to 2 Cardas RCA/XLR adapters. Plugging those adapters into the CR- 1 Balanced managed inputs.
ozzy

That is why I am using RCA/XLR adapters to only use the XLR inputs.
So, I am confused as to why he is getting the noise.
Lifting the ground switch may help.
And yes, their customer support is excellent. Ask for Randy.

Just add a XLR to RCA adapter to the RCA cables that are plugged into the CR-1. That way only the XLR inputs on the CR-1 are being used.
ozzy

I was referring to the inputs into the CR-1. Using all XLR instead of mixing XLR/RCA inputs should eliminate the hum some were having.
To me, if you can run all XLR to the sub, I would use that instead of RCA. Perhaps when using the XLR outs it provides a db boost over the RCA connection.
I am using JL F-113 subs which can contour the bass to the room.
I hope this info helps.

I see that I did confuse you. Sorry. I was referring to the managed inputs for adding a Home Theater connection along with 2 channel. So, let’s see if I can correct it / or confuse more?
The managed bass inputs come from my Home Theater equipment (Oppo 205). For that input, I am using the balanced inputs. If you use the RCA input and then use the balanced outputs, then, you could get hum.
So, if all you have is RCA from your Home Theater equipment to go into the managed input on the CR-1 then use an RCA- XLR adapter and plug it into the balanced input if you are using the balanced outputs.
Better to use all XLR or all RCA connections into the CR-1

james633,
Being able to set the crossover point from your mains to the subs is the best of all worlds.
