Any high WAF speaker with ATC sound?

Hi everyone!

I bought my very first place, and need an upgrade, but there is a lack of dealers in MD.

Before I get started, I love the SCM20 sound, and I actually dont mind the way it looks. But I know for a fact it would not be able to fill up a large space. Therefore looking for a larger speaker. I was thinking of the SCM100, but they do not mate well to my modern furniture.

Now, I don't have a wife (thank God, I am only 25), but the place will be my personal bachelor pad, and i want it to look modern and clean. The living room is about 18x27. Speakers will be on the short wall. Budge is under 6K, I can stretch it a bit, but rather not. The lower the price the better, and used of course! Inefficient speakers are welcome!

THANKS!
