Frequency Response


Would you use a sub if your speakers only went to 45Hz? Should you always use a sub?

Nice article.  It’s well written and well executed  I appreciate your honesty when you said:

”Lets be honest, these are not typical results.  This happens to be the combination of my speakers, room, listening location and, very importantly, room treatment.”

Back in the real world, DBA is how we do it, you know that. 

1st, measure what you are actually getting in your space.

get one with threads for a tripod mount, set it up seated ear level at your listening spot. 

measure what you say?

this test cd has 29 individual 1/3 octave bands, 

 

you can measure as setup, alter the toe-in a bit, move in/out of corners ...

you will definitely learn something.

now compare what the speaker's specs say and what you have been/are getting. you might be surprised how much bass you think you have and how much bass your mic thinks you have.

 

Definitely. My remote controlled subwoofers are simply fun. With the exception of certain LP's I prefer the systems presentation with the subs on and using various gain settings. 

SVS offers a painless trial period that might help you decide. I can't speak to their quality. 

The low frequency response for my speakers is 26Hz +/- (1.5 dB anechoic). At my rooms listening position they fall to 0dB at approximately 31Hz. My subwoofers most used customized EQ preset is just over +2dB @ 37Hz -18Hz as well as the variable Q, slopes and filters.  

@onhwy61 the room size is 17.5X14  and the speaker is the muraudio SP1.  Once again haven't heard live but like the design.  Do I get a decoder ring and secret passcode?  I listen to a broad spectrum from rock/hard rock/pop/jazz and classical played from loud to ears bleeding to background music
