That same reviewer has since come to the conclusion that the Altair's bass is superior in quality to that produced by the Gothams. The sound may not be as linear but the slight loss of articulation and coherence was not a compromise he was prepared to make.
Also, the quality of the the Aquila's low end is quite spectacular. It uses the same type of driver as the Altair however it is a few inches smaller. By all accounts, the Rockport room at CES was one of the top rooms at this years show. Of course, the larger the woofer the more low end traction the speaker will be able to reproduce. But then again, depends on the size of the room. More low end capability isnt always better, especially if the result is a coloring of the sound.
