Hey guys,
I'd like to thank everyone for their suggestions.
Here are my comments:
1. Sub - I did a LF test using test tones available on YouTube from 40Hz down to 20Hz.
The measurement was done only using my own ears (no mics).
My findings - the bass response is good and usable down to 22Hz (sounds pretty flat to me). At 21Hz there is a volume drop and at Hz there's nothing I can hear. The system is NOT calibrated to maybe calibration can compensate and flatten the response. In any case, at least for music, it doesn't appear to me there's a need for additional subs. BTW, the bass volume on the Tritons is set to default (mid) so there's a room to grow if needed.
2. Room treatment - my listening room is our living room since I have no dedicated room.
The Tritons are 8 feet apart, located about 10" from the back wall, 3 feet from side walls, and are toe-in around 25-30 degrees.
The listening position is 9 feet from the speakers wall and have 4 feet space to the back wall of the listening position.
I have a big rug on the floor, big sofa, coffee table in the middle. The walls are empty besides one wall which has windows and thin curtains covering them. The ceiling is clear too (about 8.5 feet high).
I did a basic test of clapping my hands in various positions and I could clearly hear echo of high-pitched sound in most areas.
Since this is a living room, I cannot put studio materials such as big black bass traps, foam tiles, etc.
I would like to know which of the uncovered areas is the most critical one - the ceiling? the side walls? the back walls? and how much (in percentage) should be covered to reduce feedback and keep a "normal" living room look.
