Hey kringle77
Xsonics is my company. Before Schroeder, the original design of that box was from Tech SoundSystems. I endorsed that cabinet back when Fred ran the company here in the states. The CT2000 was quite cool. My design is similar but addresses I believe all the issues that cabinet had. My cabinet has dual shelf ports and I've tried to model it's overall sound to be similar to the Eden410XLT which I've used for the last 18 years and loved.
I had a Tech cab...it's what motivated me to get a Shroerder 1212R. The Schroeder was better, as the box was bigger, but still lacking just enough in the low end. If your box can get the punch of the Schroeder, with some more true lows...you'll have a winner! Your box is about the same size, but has much more port area, and being as the side speaker is "outside" the box, the volume of the enclosure is larger...could be the ticket!
You know, in the rest of my life, Im very resolute and focused with what Im doing. When it comes to cabs, Im always on the hunt. But, it took a long time to find the right amp, pedals and bass too. Once I found the right ones, thats what I stick with and don't look any further. I just haven't found the right combination of tone, power and weight in a cab yet. My bass was lucky. I bought a yamaha attitude standard in 1993, loved it, bought a blue limited addition model 6 years later, a red one a few years after that, and then had stambaugh build me a custom version that made all the improvements on it that I wish yamaha had. Im looking for a cab that has the attributes of my favorite ones (d410xlt, nv610) and then makes it better. When I find that, I really don't know what I'll have to chase after. I really do like the chase though.
