I am trying to integrate a BK XXLS400 DF and a BK Monolith DF in a 5.2.2 system.
The BK XXLS400 was purchased with the intention of using it only for music as 2.1, however I was impressed how much better the bass sounds when I use it together with the Monolith for movies in 5.2.2 format. The BK XXLS is connected to an Arcam SA30 via the high level connection and to a Yamaha RX-V 685 via the low level connection. The Monolith is only connected to the Yamaha RX-V 685 via low level connection. Both subs in LFE mode when whatching movies. I set the subs to have the same gain with an SPL meter - slow C weighted.
I have done the YPAO calibration for the distances and levels. During calibration the subs phases were set to 0 on both. All the speakers are nkw set to small with 80hz crossover in the AVR. The YPAO EQ is set to flat. I then further tweaked the speakers and subs gain level using the SPL meter. The Yamaha has two subwoofer preouts, however it manages them together as one. The YPAO did a good job averaging the distance from the subs to the listening spot.
I testest for hours variants with the AVR in stereo mode (2.2) for the different phases on the subs because I was getting different results at different frequencies until I found the sweet spot (I think).
So here is where I am now:
The best combination is when I keep the BK XXLS400 phased at 180 degrees (10th position) and the Monolith at either the 36 degrees phase (second position on the knob) or at 54 degrees (third position on the knob)
Comparing the two situations at different Hz with the SPL meter there are benefits and downsides (C slow weighted average):
With the Monolith at 36 degrees (second position): at 30 Hz I gain +2 Db, at 40Hz I gain +3.2 Db, at 50Hz it stays the same in both situations, at 60 Hz I lose -0.5 Db, at 70Hz it is -1.5 Db (lower), -3Db (lower) at 80Hz and -1.8Db (lower) at 90Hz.
The opposite is true of course when I set the monolith at 54 degreee (third position on the knob).
For now I left the Monolith at the second position.
The Monolith is positioned in a corner on the right side of the couch right next to the main listening position. The BK XXLS400 is positioned almost diagonally oposite to the Monolith (to be more specific it is placed under the centre speaker and next to the main left speaker).
Is there anything more I can do to better integrate them? I do not have a miniDSP at the momoment.
Two months I did not have a clue about any of this and I was able to find so much information on old posts on this forum so a big thank you to all the people that have offered their information here overe the years.
Kind Regards,
Pat
