OK...Added 2 HSU ULS-15Mk2 subwoofers To My System

Tracy Chapman is one of many records that has all kinds of unexpected little low bass treasures. Most common is when the bass player slides off the note at the end. There's a music term for this for sure but its like they slide their finger off at the end so the note trails off and at the same time its dying out its diving deep into subterranean bass. Without the subs it sounds like the note just goes a little deeper as it fades off but with the DBA even faint low bass is so clear you feel that and its freaking impressive. 

Everybody with a sub thinks they know what I'm talking about but only us guys with DBA really know, as I'm sure you now know very well yourself.

I understand they don't know what they don't know, but I thought more members would be adventurous and daring enough to at least give it a try. Oh well, I guess a lack of adventure and ambition results in a lack of very good bass resolution and a lack of daring results in the apparent lack of caring about the absence of high quality bass performance.

As I'm sure you know, this was all new to me a year ago. Its almost exactly one year now, maybe a little more, I first learned about DBA right here from you and Duke.

Back then I was just like everyone else, maybe a little better understanding of room modes and acoustics but like everyone else stuck in the one sub rut. Only real difference being I had tried hard enough to know one sub cannot work, not the way we want it to anyway, and given up. All the evidence seemed to say its impossible. By that I mean not only that one sub cannot work, but that there was no solution. I was convinced and had resigned myself to this. 

So there was probably not a tougher customer than me. 

And yet, when Duke congratulated me on having the faith, or however he put it, to do this, as nice as he is I had to set him straight. It wasn't a matter of faith. There was no faith- or daring, nor risk, or doubt. Because the situation- the physics and the psychoacoustics- had been so beautifully explained by guys like you and Duke, and Geddes, et al. 

You guys put it all right here on this site. Sitting right there for the taking. And take I did! Read it all. Then went and built it. Because boy did I have the desire. Or as you put it, care about the absence of high quality bass performance. It had been in my estimation the weakest aspect of an otherwise compelling and very satisfying system. 

Which in one fell swoop went from weakest link to arguably the strongest. In a system that over the same year improved immeasurably across the board. That is huge. Transformative. All thanks to you guys. Well, okay, and a little initiative on my part. But I couldn't have done it without you.

Bela Fleck is on vinyl https://www.discogs.com/sell/list?master_id=101431&ev=mb&format=VinylI had one for $30 in my cart but was on the fence and since then wished I got it. But not for $60! Its out there though, somewhere. Music and recording quality is pretty good but that one track is just the best bass ever. Well I say that because one time I played it for this speaker designer, the guy had rows and rows of records and CDs, had designed a really good sub, and said it was the lowest cleanest bass he ever heard. Pretty good music too. Find it on YouTube or whatever. But be aware the bass is so low in one part you will only hear it with your DBA!

millercarbon    Makes total sense to me Chuck !
I`m laughing at that last sentence btw ...:) :)

That's great. A good sense of humor will come in handy. If you like bass try Bela Fleck Flight of the Cosmic Hippo.

Mo subs is mo betta.

When the bass is lacking we tend to turn the volume up more. That's because we don't hear low bass with anywhere near the sensitivity we hear midrange and treble. See: Fletcher-Munson curves. Now you no longer need to over-drive the rest of your system trying to make up for the lack of bass, you're able to turn the volume down and still be satisfied. 

Some of our sense of space is derived from very low frequencies. The waves of low bass are so long, 40 ft and more, they are associated whether we know it or not with large spaces. Adding the subs got you to where now those low frequencies are finally being accurately reproduced. This creates the sense of space that accounts for why your stage seems so much wider now. 

I hereby christen ye scm, DBA. Go forth and spread the Gospel!
