This new kit is far overdue, but from the looks of things, it seems that it is worth the wait. I've always desired an e-drum kit that had FULL SIZE pads like that of an acoustic kit. Roldand's TD-30KV V-Pro series was the closest we've seen, but at the cost of $7,500 US. I believe the largest pads are 12". The new Strike Pro has 14" snare and floor tom....YES!
I would call these Alesis Pads quarter sized in terms of depth They are most likely 5" deep like Drum-Tec's Diablo Series pads.
Acoustic sizes refers to diameter AND depth. While these Alesis pads fufill the diameter requirement with the exception of one floor tom and the kick drum, they don't fufill the depth requirement to be acoustic sizes. Unless you count travel kits or kids sets, but you would never use those from recording or live purposes.
While 14" floor toms exist, I wish Alesis would put two 14" floor toms on and Pro kit and one 14" floor tom on the Zone kit.
Of course you can find a 14" x 5" snare and even a 10" x 5" tom-tom but 14" x 5" floor toms and 14" x 5" bass-drums don't exist. That being said these Alesis sets don't seem like they supposed to function as both an electronic and an acoustic kit.
Not many full sized electronic kits exist, partly because some drummers chose electronic drums because of how they take up less space and are easier to transport compared than acoustics, generally speaking.
In reality, it's quite easy to get a full sized electronic kit, just buy a cheap set and do an A to E conversion. If, you don't want full sized pads, only pads with acoustic diameters, there should be cheap snare drums about 5" Deep that come in the sizes 10" 12" and 14". Companies like Pintech could convert them for you, or you could do it yourself.
What I find quirky and unappealing is the fact they use a 12" floor tom. 14" minimum please! If they are going to have two floor tom-toms using two 14" is fine, Field Electronic Drums does that. Although the second floor tom being 16" wouldn't be bad...
I would like to see these sizes minimum on electronic drums, 13" OR 14" snare, 10", 12" 14" toms and 18" kick. Granted going bigger is of course fine.
Although, I don't think I've seen these pad sizes sold together with cymbals, a rack and a brain
