Why I'm not adding a sub to my 2-way monitors for music

With a modicum of subwoofer positioning & some twisting of the dials on the back of the Paradigm sub, I used one of my fistful of test CDs (was it one of the Stereophile ones?) to achieve flat, eminently musical bass response in my listening room with my Nola Boxers down to 40 hz. From there, response steadily goes down until disappearing at just under 30 hz. All by ear, and good enough for me.

Audiophiles who do this do one of two things. They buy a sub and set it to have as low a cut off frequency as possible, which is a HUGE waste, or try to blend them in without high passing the mains. In neither case the results are mediocre to non existent.

I'm with Ozzy. Gotta have octave zero which even the full-range towers can't play anywhere near flat.

....a SHD Studio to some may be a pittance, compared to some cable commitments, but that's me being a tad snide.  But a digital crossover can allow sidestepping the major issues of integration....

Personally, I've always wanted a 'test record/CD' that I could 'sample & hold' at any point in play  Helps to focus on the details..

I helped my,neighbor, he has and did purchase on my recommendation a pair of large bookshelves (Dynaudio) c-1? Maybe, and a small Polk sub for the lows, his small modest bookshelves w the,small Polk sub, does sound very good, allows him to hit the volume a bit,more with the subs soaking yp the,low freq. 

Having just added a second sub this week in part because of the rel sale, I would add to this discussion that with the good also comes a little bad. The second sub rel s/510 added richness to the sound and much deeper sound stage. The only new problem that emerged with this improved SQ is volume. While working I was listening to the streaming service I use on my $150 2.1 computer speakers and noticed that all levels were homogenized—meaning there was about the same levels of bass and treble and so forth. Playing the same playlist on my system I found myself wanting to adjust the sub level pretty often. On one song there’d be too much bass so I’d turn the sub volume down. On another song there was too little, so I’d turn up the volume, until finally I had to put the volume at some compromised position. The sub is magical and musical but I sure wish it had a remote.
