Subwoofer between speakers?


After reading through a thread relating to the equipment rack between speakers, I assume that the sub between the speakers is also a no-no?

My speaker stands are 24.5" high, and my sub is 24" high, so I was thinking that the sub cabinet being below the mid-range driver might mitigate the detrimental effects to imaging. But I read a reply in the thread that I alluded to which talked about an amp between the speakers having a negative effect on imaging . . . therefore it stands to reason that a big bulky sub cabinet would be about 20 times worse.

I know that ideally I should experiment with placement . . . this is an extreme near-field listening room, and options are limited. I could get it to the outside of my right channel speaker . . . in theory, would that be better than in between?

@immatthewj - I have my dual opposed firing sub facing crossways (30 degrees) in my room, between and to the left side of my standmounts. Since I’ve installed the quadratic diffusers, I’ve unplugged the sub and rarely use it.

It’s crossed so low that there’s not a lot of music that I listen to regularly that has content down that low for it to make a really significant difference. If I’m playing EDM I might plug it in to give a little weight in the bottom end, but mostly enjoy music without it. Of course, that’s very much recording dependent.

Fortunately or unfortunately room treatment does really help a lot, and I’m glad I didn’t ignore the many Agon members who’ve sold me on it - because it took my humble system entirely next level. Investing in the room, is certainly an economical means of system building to get inexpensive performance gains.
And there are a lot of products out there, something’s got to work for you, looks and sound wise?

Tasmanian Devils huh? I lived in Devonport Tas for a bit, in my younger days. Tassie Devils are easily as loud and screechy as koalas in heat - unless you’ve experienced it first hand, you probably won’t believe it sounds like someone, or some fierce animal being murdered, slowly.

I understood your question. I will tell you that I have moved and measured my subs in virtually all positions around my room. They are currently between my speakers. 

The reason they wound up there was precisely because they (a) sounded best, tonally there and (b) had a positive effect on imaging & sound staging.

I have no subwoofers at all. Well treated room with outstanding setup, no need. Tried them and sold them…..

Not all subs are created equal and not all can correctly integrate. Unless you have speakers that can get to 30Hz and not screw up 300Hz doing it, subs add a realism out of all proportion to the added Hz.

As a composer friend once said upon hearing my system "Those little speakers aren’t putting out all that gorgeous bass?!?!?!?!?" ... "Every other subwoofer I’ve heard just boomed."

OP Respect for your adoptions. We always have a pair… acquired one, train for a year, then second. No doubt you have your hands full. It is hard enough to train and domesticate one dog at a time… three is got to be beyond difficult… I hope you don’t have to work and have professional training help.

 

Yes, the wave principles of subs are the same in HT and audio.

@ieales Okay if you say so. Deep bass frequencies in recorded music are between 40 and 50 Hz. The lowest note in a rock band is 42.5 Hz
