Tripwr,
I couldn't agree more. I had a very musical, sealed Vienna Acoustics Subson subwoofer and while it did a decent job, it could never touch the quality of bass of these dual OB Augies that Randy just delivered to me.
Having dual subs was a decision I made not for volume, but for balance. Certainly one of these could produce the volume of bass in my room, but I wanted the bass to be seamless and better integrated with my mains. With my single subwoofer prior, you could always tell it was coming from the one general area of the room. With dual Augies in place, the bass is simply present and fills the room much more like a pair of 2-ch mains do.
Like Randy reported in the Betsy section of the forum, these Augies that he built me using the very dense and heavy Bubinga wood are incredibly "tight and tuneful." Those were his words and there is no point in trying to come up with a more fitting two-word description. It sounds like "real" bass, from a guitar, kick drum, etc. I thought I knew musical bass with my prior setup, but realize now I was clueless.
Right now, I am awaiting my Omega SAHO's, but luckily Randy had built me a pair of Betsy OB's a short while ago that I will eventually purpose elsewhere. But I called them to duty in my living room until the SAHO's arrive. I am not sure what to expect when the Augie's pair with the SAHO's, but I can honestly say, with these Augie-augmented Betsy's, I am no longer watching my calendar - just enjoying the music. This combination is superb! Without the Augies, the Betsy's alone do not reach down low enough and with my system, are a bit anemic. That is my observation, in my room, with my particular system. Together though, they do it for me. I am going to enjoy this arrangement for as long as it takes to get my Omegas, but I will recreate this pairing with the Betsy's and OB subs (with another driver of course now that Augies are gone) in another room.
Here are a few pics showing the beautiful wood and finish Randy did for me on these.
