As I said before one point being that the Liuto's are greatly enhanced by adding a subwoofer. As the frequency response curve shows, the Liuto towers naturally roll off pretty rapidly below 80 Hz, which all by themselves is not what I would call any kind of a high end listening experience. However, they dovetail well into a good subwoofer,
The keys to integration of the towers and the subwoofer is some kind of bass management system, which is one of the strengths of most modern multichannel AVRs and a weakness of most modern 2 channel preamps, power amps, integrated amps and even most 2 channel receivers. Using a 5.1 reciever as the center of what is ostensibly a 2 channel system sounds odd, but due to their inherent flexiblity, it is easy and economical to configure them down to 3, 2, 3.1, and 2.1 systems. Since virtually every modern 5.1 AVR also includes some kind of automated system tuning facility (YPAO, MCACC, Audyssey) putting all the pieces together and getting them to sound right is facilitated for the general audiophile who is probably not an electrical engineer specializing in complex speaker systems.
You then suggest a high-end AVR, but leave it there.
I didn't really expect too much interest.
Sorry if I missed something, but were you going somewhere with the post? I value your thoughts, but I would like to hear them. If a stout amp is going to give me more dynamic range, better control over the drivers, and a better experience overall, that is what I am looking for.
One of the tools I have for showing the problems of simple 2-way systems is a model that I borrowed from Sigfried Linkwitz' web site that estimates the maximum clean SPL that can be optimistically expected from a given speaker system. For the Liuto's with 9" woofer:
Freq,Hz Max SPL, DB
You can see that the maximum SPL from just the Liuto's falls short of truly high end performance below 60 Hz. Other calculations show that the Liutos can't possibly respond cleanly to more than 100 watts below about 75 Hz so beefier power amplifiers than the usual ca. 100 wpc AVR rating can't help. I'm trying to point you towards good dynamic range from the over-all system.
On balance I'm a lot more impressed with the basic design of the Liuto Towers than most of the towers that I see kicking around.
