In Sales and Marketing's defense (can't believe I just wrote that)... If you look at an E2, E3 or E4 did you think that these were multi's. No because you have been use to hearing these model numbers for several years.
Tom Gospel the Sr. Program Director started with some interesting model numbers. 301, 502, 702 for Custom 1,2,&3. That made a lot more sense to me since you could add more models in between the levels of 3,5&7 and the last digit designated the number of arms. That was too logical I guess.
I would guess this will all be a moot point once you have had a chance to hear the familiy of Klipsch PM's, especially Custom 3 and IMAGE.
On a side note, I won't be posting much in the next two weeks, since I will be at the factory polishing 702's (C3). I welcome you to PM me or post on any Klipsch topic but my responses will be very slow and spuratic, so I appologies in advance.
I can't wait for you to stick it!
