MagnusCA,
Yeah, unless you put the speakers in bookshelves, the rear port should never be a problem.
If you have maple, try cherry to complement. (Go to Lowes and put flooring side by side, I love it.) Another option is black against maple, very stunning.
I use the orginal Ascend Acoustics in my HT and love'm. The cheap vinyl finish is the pits, but the sound and content value is superb. Very musical, image like champs, and can keep up with HT spls. The new $800/pair Sierra-1 (and matching center channel) aught to be killer. Hand matched drivers with printouts provided, 7 year warrantee, and made in the USA. Available in black and bamboo. ascendacoustics.com
