The most important question is if there is enough market for a company to make this kind of speaker. Specifically, is there enough market for Ascend to develop such a speaker. They have in the HTM-200SE and the CBM-170SE. These speakers have been around for almost 20 years, with only one change to the SE models (new woofer and tweeter). If Ascend saw the need to upgrade them again, I think they would have. Before the Sierra line of speakers, these and the CMT-340 were the only speakers Ascend offered.

Ascend is not a big company, they can not waste time and energy on something that isn't going to be profitable. Dave works a lot to get things "just right", not only with his own design/engineering, but with his OEMs to bring us excellent products.

I am 99% sure there isn't a technical issue. It is more about if it makes sense for Ascend.
