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.
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.
- 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.
- 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.
- 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.

@wokeuptobose Thanks for posting your experience with miniDSP SHD. If it is doing a great job in your expensive system, I should give up my paranoia about adding a DSP after my DAC. Just to clarify you are feeding the analog signal after Lampizator DAC to miniDSP to do ADC/DAC. I will look into miniDSP SHD. |
Yes, kind of. The Lampi's analog output goes to my preamp, the preamp output goes to the SHD. The SDH converts the analog back to digital, performs Dirac room correction and performs the crossover high and low pass, then converts the digital back to analog and sends the analog output to the sub amps and also to the mains amp. What amazes me is that all that is pretty invisible as to a sound signature. For a year I didn't even try the full signal going through the SHD. I fed one output from the preamp to the mains amp and the second preamp output to the SHD to feed the subs. It's a very versatile box. You can even run it as a preamp and/or DAC and/or streamer as it includes a Volumino licence. The DAC is good but does not stand up to the Pacific or the Vivaldi, but it comes too close for comfort. I say again, I was skeptical and didn't want to believe a $1300 component could perform like it does. |
