Hello Seaton Sound Enthusiasts,
I have been a proud owner of the original Submersive for the past 6 years and enjoyed its offerings immensely.
Recently, after reading dozens of reviews of Bass Nirvana achieved by folks with Dual Submersives, I probably got carried away and decided to go for a going for a second Submersive after consulting Mark and knowing very well that I have extremely limited placement options for the 2nd Submersive.
My only placement options for this monster are on either side of the 3 seat couch used as the MLP.
I received the 2nd Sub almost 8 weeks ago, however I did not receive the replacement HP+ Amp for my original Submersive till about 4 weeks ago. So I waited for my original sub to be working before unpacking the 2nd Sub.
I placed the 2nd Sub (Sub B) on the left of my couch (it tightly hugs the couch ...leaving any space would come in the way of the inward swing french door) and the first Sub (Sub A) towards front right corner about 13' from MLP.
With a lot of anticipation and excitement I fired up the two subs and went through the Audyssey XT 32 and Sub EQ auto calibration on my Denon AVR-4311 and made the standard Audyssey tweaks and slipped in the Spectre BluRay disc.
Unfortunately, within seconds, all my excitement died with the opening "Day of the Dead" scene at -10 DB. The bass from Sub B was drowning everything else. The powerful DTS-HD sound was totally undermined.
I tried many different tweaks such as:
1) Adjusted the distance of Sub B from 5' to 8' and the Sub A from 13' to 18' (to keep a Delta of 10' as per Mark's suggestion)
2) Reduced the Sub B level by 3 dB
3) Increased the Sub A level by 3 dB
4) Changed front speakers (Aperion Verus Grand Towers) from Small to Large and reverse
5) Changed Sub Cross Over from 80 HZ to 60 HZ
6) Muted Sub B
Other than moving 4' to 5' towards the middle of the room (from the MLP) or muting Sub B, no other adjustment I made produced desirable results.
Do you have any other suggestions or tips ? I simply do not have any other placement options in my Kitchen / Den / Theater combo (18' X 38' X 9') open to the rest of the house.
I am open to all reasonable suggestions to make the new setup work. However, what are my options with Seaton Sound / Mark ?
Thanks in advance for your expert advise and help.
