DBA for REL’s?


Been following several forum threads on the topic of subs and distributed base array. My question is would I be well served by adding two more Rel S3’s to my existing pair of S3’s or selling them for a Debra or Kinesis set that have been extensively discussed and lauded on this site? While I have some latitude with placement it’s still a LR that I share with my very tolerant fiancé so side wall placement not an option due to furniture constraints. The 4 corners would be okay. My system includes Focal 1038BE speakers and PS Audio BHK monoblocks, Primaluna preamp and Simaudio Moon DAC. Room measures 24x16x8. Listen to rock, R & B, some jazz and classical. The former pretty loud sometimes. I’ve treated the room but still not entirely happy with the LF’s. Strictly 2 channel, no HT. Budget would allow for either option. Thanks.

I suggest you add more RELs and do the DBA or "swarm" concept with them. I don't think they all need to be the same model. I tried to read everything I could on this concept before attempting it. I then reached out to Duke LeJeune and asked his advice. He graciously provided it to me--he is a generous man with his time and expertise. Anyway, he suggested I keep the subs I owned and simply add to them. I followed his advice and also paid close attention to @millercarbon and @noble100 posts here on Audiogon. I first added an S3 SHO to my two REL R-325s in an asymmetrical arrangement. BIG improvement. Now I'm waiting to drop another S3 SHO into the mix at an elevated level to further improve the effect. I don't have a dedicated room and I'm probably not getting one anytime soon. I'm less interested in it now that my room bass is much improved. 
Just received the antenna I needed to run another REL S3/SHO with the Longbow transmitter. This makes 4 RELs in the dba or "swarm" and I can confirm that 4 is an improvement over 3. I now consider my room bass issues resolved.
