Powered speakers show audiophiles are confused

Apologies I used voice dictation for my last post and it changed mains to means several times. So much for context sensitive dictation :-)

@lonemountain if you are low passing the subs at only 2nd order (12db/octave) then you pretty much have to run the mains full range. Even 24db/octave is not enough with a high cutoff if you want to prevent localization. Analog filtering on the subs can often cause phase integration issues with the mains. 2nd order will have less phase issues, but has the aforementioned issues. DSP filtering is by far best for subs.

@mijostyn - Corner loading a sub may be the best option for a room, or it may not be. If it is bad for a given room and that room has symmetry, you quite often create more problems than you solve. It would be far more often the case with two subs that pulling them forward on the opposing walls out of the corners would result in more even bass and better use of available power. Your subs will only have some limited line array effect as the line is wall-to-wall, and the floor is right there, so you already have one immediate reflection, but if it behaves as a line array, the front wall-back wall room mode is amplified. Your crossover is below the Shrodinger frequency.

So I got to run my new Sony TA-ZH1ES dac/pre/headphone amp as a pure 2 ch preamp today, sans subs, just in 2.0. I haven’t listened to a system without dsp in this room in a long time (ever?) and although the Sony’s sound is more pure to the original recording it loses a step in sound staging and overall smoothness compared to my Marantz processor in Pure Direct mode which includes the benefit of the subs and room EQ. I might tinker with setting up the subs and dsp with the Sony after the holidays but for now am just going to enjoy it as a dac feeding my Marantz processor.

Whew....some of the disinformation here...

Not in my room. 

Maybe for HT.

 Subs belong in corners.

@thespeakerdude , If a subwoofer driver is right against a wall (in a corner) as part of a line array on the floor there is no first reflection until you get to the ceiling. The wave is beginning at the wall (no delay). A line array does not radiate past it's ends. If the array is horizontal against a wall those ends are in the corner. This is unique to my situation as my main speakers are line sources. Most people have point source systems and such a subwoofer array would overpower their system. People with point source systems are better off with two subwoofers. Corner placement minimizes the effect of reflections because the driver is up against three surfaces instead of two or none if the speakers are away from the front wall. With subs in the corner the first reflections that are delayed are off the ceiling, opposite wall and back wall. By the time they get back to the listener they are late reflections and not as serious. At high frequencies things get more complicated, one of the main reasons dipoles sound better. The biggest problem with putting subs in the corner at a different distance from the listener as the mains is phase an timing. To make this work you have to use digital signal processing to delay speakers so everything arrives at the listening position in phase at the exact same time. Most people without signal processing are better off with the two woofers any where in the room at the same radial distance as the main speakers from the listener, classically this was between the main speakers but does not have to be.

@juanmanuelfangioii , I think you should change your moniker which is an insult to the greatest racing driver of all time and a great person.
