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.

dimbhaka, unless your digitizing the entire bandwidth the difference between the digital processing of the SHD and the analog of the CR-1 on the extra low frequency may be slightly noticeable in a side by side comparison due to the speed of the processing. It’s not going to suck the analog out of the presentation the way most full bandwidth processing can.

I found the JL Audio CR-1 Manual to be quite informative with my subwoofer setup. It dramatically improved the presentation of my Velodyne DD Plus subwoofers using Velodyne’s extensive Manual optimization adjustments and presets. Your in the Mob now, have fun with it.

@m-db I am not getting the CR-1, so whatever signature the SHD leaves, it will be across the spectrum.

SHD looks very flexible and I am seeing myself setting two crossovers one at around 110/120 for general purpose and one around 170/180 for female vocals; there are four presets in SHD. This would have been almost impossible with CR-1 as a change in crossover frequency means new phase alignment.

such a crime to high pass the Spendors but I do hope it works out for you. difficult for any sub to keep up with them.  

@avanti1960 , my main aim in high passing the Spendors is to eliminate intermodulation(amp) and doppler distortion(speakers). I will also be setting one of the presets to disable the subs and run Spendors full range.  I will post my experience in this thread. 

Also, I have been reading such good things about bi-amping and adding subs with high passing the mains is another form of bi-amping.

PS. In this journey, I read your subwoofer threads in the other forum.

Yes, thank you.  I have learned a lot in my journey!   

Some speakers work well with the right subs, some do not, and ultimately if you value speed, dynamics and lightening burst timing no subs are best.  

Not everyone values that however.  

Good luck!
