Post Subject: Bass treatmentPosted by anthony on: 6/25/2023
I've managed to make my own room treatments thus far, all bass oriented and although some broadband absorption has been used the bulk is effective 30hz - 500hz. It is an architectural type of solution where I have a covered the front and side walls and massively altered low end reverberation time without much changing midrange and top end times nearly as drastically... they are very even now from 40hz -20khz.
The major hurdle I have that most will not is that mine is a soundproof room. I can close a door and the rest of the house has no clue if I have music playing loud... although the closed door is a give away! That sealed room is super bad for room modes as little energy leaks through the walls and it all comes back as cancellations and reinforcements. At the sidewalls , where the TT sits, the 30Hz mode used to be 18db to 21db louder than what came from the bass cannons... since room bass treatment that is now 6db lower than that issued from the speakers...24dB to 27dB attenuation!
As a result, the quality of the bass is superb, almost unbelievably good, but it is also now quieter than it once was as much of what I used to hear was "old news" issued half a second or more ago, so I expect to rebalance the system shortly. This is a long way of saying that I have already bass treated the room as it was the only conceivable way for me to even out the room frequency response without putting literally 1kW of amplifier power into a pair of Vitavox 15" per side, at 75Hz, which of course will not work. A little bit of bass treatment remains to be completed, on the ceiling this time, and then room tuning with diffusion and perhaps some midrange absorption, depending on how things sound.
