Why do you guys pursue a flat frequency response when you buy a subwoofer?
I understand, I still have my original M&K Volkswoofer and Satellites. They still play in my office. I had the Volkswoofer amplifier and driver surrounds renewed last year. They sound as good as I first remember them and bought in 1983. I will say though, they don’t shine a light on my primary system. |

These guys try subs and abandon them because they can’t get it to integrate right." Very interesting. To the best of my knowledge I have yet to have a subwoofer system customer fail to get satisfactory integration with his mains. In most cases they run their mains fullrange and then blend the subs in. Therefore I must give credit to the off-the-shelf Dayton Audio amplifier I use, and to whoever designed it: https://www.parts-express.com/dayton-audio-sa1000-subwoofer-amplifier-rack-mountable--300-811 Deep: "I sure would not want to add another adc/dac into the chain with a subpar DAC on something like miniDSP for bass management (when i have a Denafrips DAC in my 2 channel setup). Guys i know have waaaay more expensive speakers, DACs, monoblocks, etc on their 2 channel music setups than i do. They are probably not gonna do that either. " You bring up an excellent point: How do we roll off the bottom end of the mains without any undesirable side effects? Not sure there is a totally transparent solution. Therefore when I design main speakers with subwoofers in mind, my mains do not need a protective highpass filter unless extremely high SPLs are desired. Their inherent bottom-end rolloffs are intended to blend well with the variable 4th order lowpass filter of that Dayton amp. Deep: "It may be a loaded market chunk which is out there i.e., if a manufacturer chooses to tap into it and cater to their systems better (monopoly for sure). More DOFs or.... whatever the R&D/solution may be to better integrate them..." I hadn’t really thought about it in terms of degrees of freedom until this thread. I think there may well be a correlation between (useful) degrees of freedom and good integration with the mains. Lacking the financial resources to develop my own subwoofer amplifier, I count myself lucky Dayton makes an amp with a parametric EQ and a fully adjustable phase control. My individual passive subs have some adjustability as well. Duke |
Deep pondering your post... what does REW run result look like for in room ? The frustration in room 2 seems to be more with recording variations? Can you post a frustrating track title and the SPL where troubles begin or end... Also you can high pass the mains with a 6 db per octave filter available from Vandersteen which is part of his systems engineering approach to powered bass integration- not advocating a switch in your speakers.
