Subwoofers and Crossovers.

My system is Cary DMS-550 / Luxman L-507uxii / Spendor D7.2

 

After researching I decided to add an active crossover and two stereo subs to the system.

 

  1. I am looking at JL Audio CR-1 as the crossover.  This will take the pre-out from the Luxman and feed mains-in and setup the Luxman as separates. Is there anything else that I should look at?  I am only looking at analog solutions.
  2. After looking a REL, Rythmic, SVS, Martin Logan and JL, I am leaning towards getting two JL Dominion D110s.  Would these subs be sufficient or should I be getting JL E110s? I won’t be using the internal crossovers, so primary concern is fidelity.
  3. If I am unable to treat the room properly, I may be introducing a DSP solution just for the subwoofers.

 

I am looking for some advice from people who have walked this path before me on both the active crossover and the quality of D110s. 

I would appreciate any advice on this process of integrating subwoofers into a two channel audio system.

@khiak Those Funk Audio subs look awesome and am sure they perform well, but they are not for me. Not only are they beyond my budget but they are also really big.

@asvjerry If only it was so simple. I realize digital crossovers are really good, but I am reluctant to pass the analog output of my DAC through  an ADA process. I am starting to think I am being irrational here.

@dimbhaka, *L* It all seems irrational after a certain point imho, but....*shrug* ;)

I like to set the 'general environment' to flat response as much as practical, given that I'm running diy omnis' and dipoles in a 'highly compromised' space with one DSP equalizer, and tweak to taste with another.

"Compromise" as an artform....*L*

You might give it a go as an experiment with a minimum outlay.  I'm using the Behringer to pass the lower bass to a sub to keep the omnis' into the range they seem 'comfy' with, since lower bass freq. are 'omni' in nature anyway....

Works for me....if not for you, you can always curse me with whatever seems appropo.....*L*

I've already got the 'underwear into the crease' version, so try something different and surprise me... ;)

I use a MiniDSP SHD as an active crossover for my passive 18 inch subs. I also use the included DIRAC room correction that performs DSP on both the subs and the mains.  bought the SHD from George at Deer Creek Audio and also gladly paid him to set it up and modify the program when I make system changes. It's all done remotely using a laptop and Team Viewer software. I never wanted to run my entire signal through a $1300 box, but I don't hear the SHD in the circuit except for the nice effects of the room correction and the seamless sub/mains integration. It's not the solution I would have expected I would buy, but it works extremely well. The SHD also allows you to time correct for the subs being set on a different plane than the mains. The MiniDSP SHD has a huge feature set for the money.

[fittebd]  If you had an older Velodyn before they ruined themselves, 

I drove by the Hellyer Av. San Jose location Thursday afternoon and the Velodyne Lidar parking lot was almost full. What do you mean by, ruined?
