Hope that any of you professionals on the forum can help me with an issue I have been fighting with for more than a year now.
Problem is that i can not get not get the subwoofer to deliver at all after calibration. Regardless of place in the room, regardless of the settings in the receiver, regardless of the volume of the subwoofer it virtually lacks all punch when listening to music in both stereo and 5.1 (movies works ok though, at least for fairly deep bass) . I have tried all possible settings, SD pillows on the subwoofer , Super Pikes on the speakers , small vs. large in the receiver, the LFE + main / LFE , Audyssey turned on / off , Dynamic EQ on / off , phase settings, etc etc. (as you can imagine I have had some time to experiment with this but unfortunately I have not found any solution).
The other day something strange happened when I once more decided to change the position of the subwoofer to the room's last option. I did not reset the receiver nor the subwoofers internal eq (Velodyne SPL -1000 Ultra) . Even though the calibration had been done (both Audyssey and the subwoofer internal eq) in a different part of the room, bass was suddently there at the new position. I listen to some stereo tracks and viewed some old music videos on VH1, midbass, punch in the bassdrums and everything that previously had lacking , was present. The sound stage were no longer flat and I could feel the low end and all in all quite an improvement in sound stage (the sound were not 100 % due to the fact that the subwoofer were actually calibrated for another part of the room, however better than before). Obviously i though that I had finally found the optimal location for subwoofer placement in the room and therefore calibrated once again - first subwoofer (set it to direct which in order for the receiver to handle bass management) and then Audyssey 8 positions (which I understand is the correct order - first subwoofer, then Audyssey) with a tripod . After the calibration had finished I manually changed all speakers set to small, crossover at 80 hz , leaved the subwoofer volume at 20 (set to -4 dB in the receiver, calibrated to 1/4 of the total volume, otherwise it hits the lowest value of -12 db). Afterwards I tried some bass heavy music and to my dissapointment I was back at square one, no punch, just flat and dull. It doesn't help to increase the trim levels in the receiver / subwoofer volume via the remote control, it just ends up in bad sound with dist. I own quite many music blurays which has received good reviews , especially for low end. They sound completely worthless in my setup, the subwoofer does not integrate at all, even when the DTS-HD tracks should be really good.
Since I have now finally heard that the system can actually deliver (obviously nothing wrong with the subwoofer), however calibrated for a different part of the room, it feels like either Audyssey and / or Veldones calibration messes it all up. Are there anyone who have experienced similar problems and managed to find a solution? I can not think of anything else to try when he only decent option seems to be to calibrate the subwoofer in one place and then move to antoher, however it does not feel like a completely optimal solution and certainly not the best. At one time I borrowed a Denon AVR- X4000 (with XT32) without better results, the receiver is probably not the problem. Have also tried with an Anti-Mode 8033 Cinema, result is the same.
I have the following setup:
Receiver - Denon AVR- 3313
Fronts : B&W CM8
Center: B&W CMC
Surround: B&W M1
Subwoofer: Velodyne SPL-1000 Ultra
I really hope that somebody knows how to handle this, quite annoying situation. My previous system was worth probably 20 % of my new one and actually delivered a more complete soundstage, the subwoofer was in the same room so it's hard to think that the room is the issue. But who knows.....
Thanks in advance for all help that I can get!
