Thanks for the insight, Bogg.
After setting to mono and recalibrating both subs I realized I had the level on both subs lower than 75db as all other channels. The biggest reason for this is the fact I get a “rattle” from my left sub at certain playback levels and or frequencies. I had forgotten about this.
I have all B&W; 800D L/R, HTM2D Ctr, CT8.4 side surrounds & rears, SCMS x4 ceiling, DB1 subs x2, front left & right
The issue I have is the cone moving so much it kind of screach or rattle. Hard to explain the sound. At first it would seem as though it is moving against the floor but that is not the case. It is on feet going through a cork floor to cement pad as is the right sub. I have extensively explored reasons for this and have found no other cause other than the movement of the cone.
Very irritating to say the least.
The subs are about 10 years old and I know there are better performance options for subs and have to believe the technology has improved today.
While I really don’t to spend the money right now I do want to consider replacements options. Ideally I’d like to get the best performing subs that I can, tight bass, more power than I need for headroom.....
My room was acoustically designed and is a dedicated room measuring 27’ deep x 21’ wide, 10’ ceiling. While not perfect, the acoustics of the room are excellent.
The Datasat RS20 was calibrated using dirac and bass management. I don’t imagine I would need on board eq or room correction as many seem to include today.
Any suggestions or comments as to what others are using would really be appreciated.
I realize this isn’t necessarily the right forum for this but would value feedback from those of you also using the Datasat.
