Turned Off My Subwoofer ... And My Speakers Sound Great


I’ve had a pair of JA Pulsars (non-Graphene) for a couple of years now, and have been using them with a subwoofer. Today, I noticed that my Pulsars sounded very different. There was an expansion of soundstaging, the bass was more articulate and robust (i.e., it had more weight to it), and the highs really sparkled.

This was somewhat different from the sound to which I had become accustomed, so I looked on the panel and discovered that the sub had been turned off. Apparently, my wife had been dusting around my listening room and had accidentally hit the off switch.

I am kind of befuddled by this because I thought use of the subwoofer was supposed to achieve those sonically pleasing effects. Apparently not in my case. Have any ’Goners had this happen? I’m really happy with the "new" sound sans subwoofer, but continue to wonder why that is. I mean by all objective measures, the sub should improve the sound, not detract from it. I just don’t get it.

The only thing wrong with many subs in most cases is the additional expense and complexity for what you gain. I’d focus on getting one sub set up right for your sweet spot first before even considering more. That alone is hard enough to do in many cases. Then if you need to have properly tuned bass in other spots, arrays of subs to distribute the bass more evenly across the room is a solution. You don’t add more subs to get bass right in one spot. A suitable sub tuned properly is the most you need. With larger full range speakers and/or in smaller room even 1 well selected sub set up well may not add much if anything.

This is all for 2-channel music listening of course. Home theater is a different ballgame.

Having said all that I would not enjoy my relatively small and not particularly bass extended kef ls50s in my 12X12 room nearly as much without the sub. With it, there is not much to want.  The ls50s are fabulous speakers for smaller rooms within their limits.
The sub was probably set at too high a level and/or the low pass filter set too high.

In other words set for too much bass which obscures the rest.

Not uncommon for folks to set their subs too high.

If suspended plywood floors that will also muddy the bass and obscure detail. Try placing sub on an isolating platform if so like Auralex Subdude.
