Honest Experience on Effects of Subwoofer Please


I have read countless of threads on people’s experiences with subwoofers but am still confused. Although I don’t have any experience with high quality music subwoofers, I have been using a decent sub in my audio system for the past 18 years or so. The sub went in and out of the systems and various rooms throughout the years as I was not convinced if the sub was contributing anything to the system. At times I felt I could hear an improvement and at other times I thought the sub wasn’t doing anything. If I bump up the volume and crossover frequency on the sub to hear a larger impact, it’s overly done.

I am aware that a proper set up and/or quality of subwoofer is crucial to ensure a successful implementation of the sub(s) in a system. Let’s just assume that everything is done properly.

To cut to the chase, do people hear a small or appreciable difference with subwoofers, or it’s a big night and day difference? I know everyone’s expectations are different but I’m reading different opinions and experiences on this forum. For the first time in 15 years, I am considering a sub upgrade and have been in communication with the sub maker and dealer. I just wanted to get a clearer picture on the situation.

So, coming back to the question, just two questions;

1. Do people hear a small or appreciable difference with subwoofers, or it’s a big night and day difference?

2 Do subwoofers just fill up the missing deep bass below say 40Hz or 35Hz where the main speakers won’t reproduce, or they will also augment the mid bass and upper bass by producing a punchier sound with better kick, heft and dynamics? The drums or kick drums are usually in the region of the midbass and upper bass, not low bass.

Posts like the one below taken from another thread make me confused.

Many a sub(s) implementation appear strikingly meager, malnourished and of secondary consideration in its overall implementation. I'm guessing it's that mentality again; why have a couple or further multitude of (sub-)bass behemoths lying around in the listening space when you can have all but one the size of a small cathouse?

Because it isn't only about extension, but rather, as you so rightly point out, it's also and not least about the added sensation of power and effortlessness of presentation to instill that live feel of music, including the contribution from the main speakers here when properly high-passed.

And yet, what is it about "hi-fi" that very generally turns its back on the inherent power delivery and (truer) size of music and instead relegates it to something brute, unsophisticated and undesirable? You'd certainly think that the way this vital aspect of music reproduction is sorely dismissed either (and mostly) in silence and vehement reluctance, or even downright ridicule.

Anyone can feel free to implement subs the way they see fit, that really goes without saying, but augmenting the mains run full-range with smaller subs is really only the tip of the iceberg. Perhaps it points to the need for a more radical and re-defined approach in speaker implementation that should more readily see the acceptance of DSP and active configuration, in addition to letting size of speakers and subs have its say. The latter part has been stubbornly missed out for decades, so one wonders whether it will ever find any real traction with audiophiles at large.

It seems the way it works is that if you can't go the whole nine yards with regard to physics then make it appear that not doing so is actually to the benefit of sound reproduction; indeed, it becomes a rationale in itself. 

A lot of silliness get passed around with topics like this one, and all bloviating aside, subs aren't that difficult to set up, more than one helps tame standing waves but one sounds much better than none, and don't be afraid to try 'em. I have a few older RELs (no high pass nonsense needed) bought used and they're great. 

@wolf_garcia, I hate to be a PITA (not really) but, if you think subs are easy to set up then you have not heard them done correctly. 

@phusis , When enough audiophiles hear subwoofers set up correctly, digital cross overs and all, the acceptance will grow like a snowball rolling down hill. All my audiophile buddies on hearing my system got subwoofers and digital crossovers with room correction. None of them are dyed in the wool analog guys but still.

It turns out that with the proper equipment subs are easy to set up. The computer does it for you. It measures your system one speaker at a time and adjusts delays and volumes appropriately. The only thing you have to do is select a crossover point and slope. The system I use now lets me change crossovers and slopes on the fly while I am listening which is very helpful. 

Wolf,

Thank you for the rare glimpse of common sense on an audio forum. People make so much of this stuff harder than it really is. IMO, it’s so they can feel really smart for solving the (usually non-existent) problem.

I cross my mains over at 100hz.  I have an SVS Ultra 13, 155 pound behemothof a sub 12” behind my listening seat.  I can feel kick drums in my chest and even throat.  Music has become visceral.  My stereo can pound you into submission.  It makes grown men giggle.  Its good
