Where are the subs?

In listening to the Bach Toccata and Fugue BMV 565, I was struck by how well the organ pedal notes are reproduced since I moved my primary setup to another room. I complemented myself on a fine job of integrating the Velodyne HGS-10 subs with the KEF Ref 1s, using 40 Hz low-pass with 24 dB/octave. But as I thought about it, I didn’t recall connecting the SMS-1 bass manager to the Ayre KX-5 Twenty preamp. I checked. The subs were not connected. The Ref 1s alone where reproducing that satisfying bass. Amazing for stand mounted monitors. I sure as hell didn’t expect that. To confirm, I played the Saint-Seans 3rd Symphony. Same result. Makes me wonder if I need bother connecting the subs.

@dbphd, the DBA concept and what you can accomplish with your SMS-1 are pretty much one and the same. Use what you're comfortable with or try both and see what you prefer. I have used the DBA concept with 4 subs for a few years now. No room correction was ever part of the equation, didn't feel the need for it. I am trying out a line array concept now that member mijostyn recommended and find this method useful too. IIRC, he uses DSP in his setup, but again I do not. Ultimately I think the use of 4 subs will make a nice difference in your system.

BTW - was at the show in Long Beach yesterday and ran into Doug. Had a nice time. I'll be heading to LA in the next coupe months so I'll try to make a point of stopping by.

@dbphd, We may have spoken about this before so forgive me if I am repeating myself, but have you tried a 100 Hz cut off? Does your Marchand have a high pass cut off as well or are you running the Kef’s full range?

I think for Casa Dorinda the system I would like to see you use is the Ayre 5 Twenty with the Codex, Sonore, and LS50s. Add 4 subs to that and be done with it.

Won’t head down that way until late July so that should give you enough time to get the subs repaired.

@dbphd, I wasn’t aware of the QX 5 Twenty having that capasbility. I would certainly go with that over the Sonore/Codex combo.

I was just on the Marchand website looking at their parametric EQ for a project. Interesting choice on the passive version. Just curious, was there a specific reason for that?

Yes use the LS50s with sub array.

Interesting on the passive filter. I may look into it, although I have been very happy with the Beveridge RM-3 active crossover.
