Speakers better without subwoofers? Crossover and synchronization issues? What do you do


 

I bought main speakers 25 years ago, spkrs seemed to have much larger bass drivers back then,  and nowadays subwoofers are a staple in audio systems, while bass drivers have tended to get smaller in diameter on main speakers, why is this?

Wouldnt it  be better to have a larger bass driver in a main speaker   rather than having timing issues with a pair of subwoofers? Also seems crossover designs might allow for a better sounding experience if they are part of a main speaker. I do have a Single subwoofer that I use to vibrate the room which works pretty well watching movies, simulating tank movement is really cool although don't use it in two channel listening at this point since it's older.

The reason bass drivers have gotten smaller is they are much more capable (longer throw) and faster (less overhang). Huge drives have inertia and are not nearly as articulate. Lots of folks have subwoofers… I suspect very often they are not adding to accuracy but over accentuating the lower bass.

I have gone to a number of homes and immediately turned the subs almost off… and the sound improved dramatically. I got rid of my sub woofers in my audio system a number of years ago. My speakers are flat to 28hz. They sound perfect, perfectly coherent. No integration issues. But then I don’t listen to hip hop.

Proper subwoofer adjustment is key, and possibly rare. There are pros and cons with everything in audio, including woofer size, mass, excursion, etc. Many, many that I’ve heard are used as the main attraction, which is fine if that’s what you like, but it’s not natural to acoustic instruments.

There are certain ranges that some woofers do well, and some that they don’t. The trick is trying to optimize what you have. Most subwoofers I’ve heard are set too loud relative to the output of the mains, and in many cases the low pass crossover frequency is set too high. The male vocal range can dip below 70 hz, which is not the best range for most subwoofers to operate in, yet many do. I try not to feature the sub, but use it only to augment what my main speakers do in the lowest octave or so. IME, subs work better set below 60hz, and when they’re barely noticeable except for passages that have deep heavy bass.

the subs in a two channel system shouldn't rock, vibrate, shock, etc. They should blend in, as if they didn't exists. When dialed in correctly they add another layer to the soundstage, and depth and punch to e.g. the drum
