Hi Bob,
Thank you for the feedback and thoughts. Without it designers can never improve. I wish I was in the room when you were there, so we could address the strengths and weaknesses of the room loading the bass frequencies correctly and to your taste. Unfortunately, I was only in the room for less than 1 day to speak to fellow audiophiles, because I had other obligations in Denver that weekend. So I don't think we crossed paths.
One of the design objectives for the Symphonia 72R was as follows-- Use the ceramic Accuton midbass driver for frequencies including bass up to the tweeter's frequency transition. I've found the 2.5way format yields a very coherent transition between midrange and bass frequencies with a very fast transient response.
The trade-off versus the use of a subwoofer in a 3-way for the lowest frequencies is the extension into the very low end and sensitivity. In other words, Iron's law dictates a much larger box volume coupled with a larger area driver, or much lower sensitivity to dig below 30-35hz. For the S72R, I chose an average sized bass reflex box but the result is higher sensitivity using the selected dual 7" bass drivers. These are all trade-offs to meet my design goals. In the right sized room, and properly positioned, I believe the Symphonia 72R will yield a very satisfying bass response. In my system, I'm driving them with a 60 watt integrated with satisfying results.
Best Regards,
Jed
