Ron, at the 0:56 second mark you said, (paraphrasing) "... if we fix the harmonics, that will take care of the primaries." Then at the 2:00 minute mark you imply the opposite, when you say - "... deal with the biggest problem that you have. If the problem is 50 Hz, then fix 50 Hz. Dealing with the primaries makes sense. Focusing on the fixing the harmonics does not. Please clarify for us.
We mean - treat the harmonics. They will dampen the primary enough to control it. In small room acoustics, we need a lift in the sub-bass region. In large rooms, targeting is not recommended but the BassMod diaphragmatic absorbers work excellent and have a broad range.
@@JHBrandt Ok, that might clarify a bit your room mode calculator that has the harmonics to target with membrane traps. 29hz first modal is a bit too low to treat diy anyway, but treating 58hz might be doable. But do you need then target also 87hz that is third harmonic of 29hz? 58hz in this case being the first modal null.
@@digidope I don't recommend "targeting" measured issues. If the primary modes are as you say, I would definitely recommend buying the BassMod centered at the frequency of interest. But they are designed, normally, to have a low Q... So they don't notch. 😁
Fixing the lowest fundamental dip (eg., 50hz) seems to make more sense with lessening the higher harmonic dips without completely overdamping the higher harmonics. If we went the other way round and treated the higher harmonics to reduce the fundamental dip at 50hz, I imagine we might overdamp the Mids in order to correct this 50hz dip. I may be wrong. Would need some data points to prove the effectiveness of this strategy
Good question. After about 1000 recording studios we have found that this is the most effective and reasonable way to treat the bass. - Treat the harmonics and you'll get the fundamentals. Too many neophytes claim that they need to target certain frequencies because that's what they are reading with their DIY software packages in these very small rooms. It really doesn't work that way. And all I can say is that I've been there and done that. I want to share what I know works very well.

@@JHBrandt So you don't use high-Q membrane traps in your designs anyomore? Those seem very narrow band but target only the problem hz.
@@digidope I have never used high-Q diaphragmatic traps. 😁
