Magnepan 30.7

The ideal line source would be like a narrow pole - very narrow and from floor to ceiling (with no mass). With real world materials, Magnepan aspires to this ideal.

Imagine if Magnepan repacked the 30.7 tweeter/midrange in a 10 inch-wide panel and sold it with small dynamic woofers that could be hidden. Such a hybrid would have all the problems that have plagued all hybrids, but there is no acoustical reason it would not work in a small room.

However, the bass panels of all Magnepans are big. The 30.7 bass panel is huge. And, yes, there is an acoustical problem with putting a big woofer in a small room: excessive midbass.

However, Magnepan has solved the problem of excessive midbass. The 30.7 has adjustable midbass control - in addtion to mid and high frequency adjustments. If you can handle the aesthetic issues of big panels, there are no acoustical reasons you can not have a 30.7 in a smaller room. 

A word about setup: whether the tweeter is on the inside or outside, the tweeter should not be closer to the listener than the bass section. Measuring from your seated position, if the bass panel is 10 feet, 6 inches, the tweeter should be at least 10 feet, 7 inches.
