@brunomarcs which model Morel drivers did you get?
Distributed Bass Array configuration
Please, I don't want to debate the merits of the DBA nor of those who espouse it. I am considering adding two more subwoofers to a system that has two already. To those who use a DBA,I am interested in how you have configured them, specifically--
- Do you run in mono, or do you split the array to run in stereo?
- What is your approach to setting phase (delay) among speakers that may be facing different directions and are different distances from the listener?

@brunomarcs no I do not but have been intrigued by Morel and want to try out a set. I built my own DBA as well using Dayton Audio drivers in sealed enclosures. I do not use the Dayton Audio amps, but rather a pair of Bel Canto mono blocks to power the low end. I have an Accuphase F-25 for the active crossover with low and high pass filters. |
@mike_in_nc place a phone call to Duke Lejuene at AudioKinesis who manufactures the Swarm which he'll tell you was based on a theory by Earl Geddes. If you search the web I think there is also a white paper out there by Earl that explains the concept and placement ideas. Duke provided a placement guide based on the Golden Ratio that I dug up somewhere. It is a good start but with some experimentation you can dial it in. He has gained a wealth of information on this topic and is more than willing to share. I did my own swarm using 10" woofers in sealed boxes. Crossed over at 70 or 100 Hz depending on the mains speakers using an Accuphase F-25 frequency divider. Two woofers firing towards the walls, two woofers firing into the room, one of the four woofers raised to ear level. I put the woofer nearest the corner out of phase by swapping the leads. Since you have line source ribbons @mijostyn has an interesting set up for that type of arrangement I used with my Acoustat Model 2 speakers. His theory in effect creates a line source for the bass. You can chat with him as well to get more information. |
