DEBRA / SWARM DSP?

You are welcome any time veerossi. Never heard Tannoys so can't say much except Moabs are pretty darn impressive. Especially since mine have been taken apart and treated to some crazy good tweaks that must sadly for the time being remain secret. (Or at least off-line.) Clean, clear, dynamic and detailed without any edge or hardness, and able to play good and LOUD with little power and no strain, they are the perfect speaker for me. Or to paraphrase the Tommy Lee Jones line in No Country For Old Men, "If its not it'll do till the real one gets here."   

What I would like to hear is this same setup with a SET. Bet it would be mesmerizing- even more mesmerizing I mean!   

I came here looking for help before doing that LOC mod. Something I always knew was possible but never knew how until, necessity being the mother of invention, I went looking. https://www.epanorama.net/circuits/speaker_to_line.html

Kind of wondering why you want DSP? Dayton already gives you a lot of range, and with four subs the bass ought to be pretty darn smooth already? Have you tried connecting them series/parallel to hear which you prefer?

I just received the following PM from kenjit, quoted below in its entirety and unedited.  

hi

would you like me to come and assess your speakers? free of charge. They will need to be equalized to your ears. I bet you I will be able to find many things wrong with your speakers! who is Deborah?

You are welcome any time. Consider it a standing offer. You and anyone else. In Redmond, WA just two miles east of beautiful Lake Washington, about a half hour north of SEA, which is where you would land. For out of towner's we have a spare room all set up and you are welcome to spend the night. Just PM to make arrangements.  

Your timing is good. Main weakness now is acoustics. Planning on consulting with our local expert, Mike Lavigne. But first-hand impressions and experience, you can never get enough. 

It will be a long trip, but if you come late spring or summer we are real close to some absolutely stunning scenery. Heck, Mike is up so near the pass his back yard will impress anyone not born in Yosemite. That's what the Portland group did last time, pulled a train from my place to his. 

Any time. Let me know.

I have the same 2 amps with 4 subs just like that. Plus one more because, millercarbon. You already have a lot of EQ built into your Daytons. If you really want to double down with DSP the simplest is to connect the DSP to each amp. The DSP is equalizing bass response. It doesn't know which or where or how many speakers. It only knows frequency and volume. You could hook all 4 subs to one amp and use it. Same result each time because, same DSP. 

The LOC you built with your 2 resistors is identical to mine. https://systems.audiogon.com/systems/8367
