Hello mizike,
RCA cables are only utilized to connect line-level outputs from other components to the Swarm’s Dayton SA1000 sub amp’s line-level Left/Right and LEF inputs. Single lines of speaker wire are utilized to connect all four subs to the Dayton sub amp’s two sets (A and B) of pos./neg. speaker-level output terminals in a series/parallel configuration.
Series/parallel configuration consists of a single speaker wire from the sub amp’s A pos. output terminal to sub#1’s pos input terminal, a single speaker wire from the sub amp’s A neg. output terminal to sub#2’s neg. input terminal and a third single speaker wire from sub#2’s pos, input terminal to sub#1’s neg. input terminal to complete the series/parallel circuit for subs #1 and #2. Subs #3 and #4 are also connected in series/parallel configuration to the sub amp’s B pos.and neg. output terminals in the same manner. Any signal loss caused by long speaker wire runs are compensated for through increasing the Dayton sub amp’s volume/level control. Series/parallel hookup also allows the Dayton amp to be under an overall single 4 ohm load, even though each of the individual 10” subs are rated at 4 ohms, and therefore the amp is able to output a total of 1,000 watts to power them. The overall result in my system and room is mono bass from 4 relatively small subs at 12”x14.5”x28” and 40 pounds, that Is sufficiently fast, smooth and detailed to blend seamlessly with my very fast, smooth and detailed Magnepan 3.7i main speakers. At the same time, the total bass output is capable of being as deep, powerful and dynamic as the source material calls for, down to 20 Hz +/- 3 db and at an output SPL of up to 115 db.
The 4-sub DBA concept has proven to be an excellent complement to my main speakers, since it provides the high quality, powerful and dynamic bass below about 35 Hz that my main speakers, having a rated bass extension of 35 Hz, are not capable of providing. I also realize that my main speakers having a bass extension of only 35 Hz is actually a blessing in disguise. This is because I’m certain that having 4 independently positioned subs in a distributed bass array in my room results in superior bass quality performance than 2 bass transducers, being restricted to being positioned in the same relative room position and panel as my main speakers’ other transducers, would be capable of producing, even if they were planar-dynamic dipole panels with bass extension down to 20 Hz +/- 3 db and capable of doing so at a 115 db SPL
