Love the new torii towers. Would be really interested if you guys did a td-x version of the s4 tower that's also a sealed design. Are there any plans to put either of the torii towers up for sale as finished speakers?
Both versions integrate with subs well, but the P2 is optimized for deep bass extension without a sub, so highpassing and then using a sub negates one of its primary benefits. The S4 on the other hand is optimized for high impact and sensitivity with an easy impedance load at the expense of deep bass extension. This is the one I would recommend for subwoofer integration, simply to retain all the optimized benefits.
