Stuart - then horns are a natural choice with bass bins being the most efficient and with corner Klipsch type horns getting the very loudest possible for modest power. The issue will be suitable placement of corner horns and size - the Klipsch RF-83 gets round the efficiency/size probelm nicely but it dips to around 2.8 ohms so unlike bass bins generally regular multi-woofer designs might pose issues to drive them - this can result in IMD distortion and clipping.

One other thing, horn speakers tend to have a narrower dispersion pattern and may or may not evenly fill your large space - placement will be more sensitive than with your Totems. As a general rule of thumb - the very high efficiency designs tend to forgo the even dispersions and even frequency response that you get with low efficiency speakers - so it can be more challenging to find the right solution. Good luck.

Shadorne,I appreciate your description of the advantages/disadvantages of horn speakers. As I have very little flexibility re: placement, it sounds as though they might not be the best choice.Thanks for your input.
