Any update on your purchase now that you've lived with them a while? Have you many a sub choice yet?
Thanks!

The Sierra-1s arrived in time to offer some relief for the cabin fever running rampant on the glacier bound, near prairie.

Nearpraire, now if you want the ultimate in SQ possible, you need to add a pair of stereo subs of high quality. You MUST use a proper active xover to split the signals to the subs and mains properly. I can recommend a very compact solution, that meets the absolute highest possible standards for music reproduction, if you are interested in making this critical upgrade. Do as I instruct exactly, and you will gain improved mid-range clarity at moderate to high levels, increased radically LF SQ and extension, and increased realism(solid extension to the low 30Hz range improves the realism and apparent ‘depth’ of recordings). Warning: my recommendation will not be the typical retail product advice you typically hear. I give usually unique, higher performance advice to make the most difference for dollars spent in the relevant situation.

Ok Chris, I'll bite. What's your recommendation?
