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.

Serious question.
Do you think a room the OP,s size of just 10x9x8 could handle a DBA or even two subs?

Yes. Without a doubt. The whole reason for DBA is to smooth out room modes that are created by rooms being smaller than the lowest wave lengths. Totally stands to reason that the smaller the room the worse the modes and the more the benefit of multiple subs.

I think where people get screwed up is thinking that adding subs means more and more and more bass. This is NOT the case! Each sub that is added the volume of ALL the subs is reduced. There are more subs but each sub puts out less volume. All together they add up to the right balance. Only better. Because to get that balance with one or two subs there’s always a hump or two that you have to live with in order to not have a suckout hole or drop-off. But with multiple subs the humps are almost non-existent and there is no dropout. That’s why everyone with a DBA raves about how smooth, fast, articulate and DEEP their DBA goes.
Or sometimes more is more. Your problem was you had a sub. All rooms have problems with bass modes, and the smaller the room the worse the problem. Unfortunately you went for the proven to fail approach of trying to suck up the bass with room treatments. The proven to succeed approach is four subs. Don't need to be big, especially in such a small room, but the small room only makes it more essential that you have more bass sources.  

The results you were looking for, they do indeed happen when you get a distributed bass array. Do a search. Study the system. https://systems.audiogon.com/systems/8367 Look for comments from Duke and Tim. Everyone with a DBA will tell you its the way to go.
