I have the opportunity to buy either one of these Speakers for $4,500-used. Both are less than 2-yrs old and in excellent condition. On paper they seem very similar with the one major difference being the 937Be's high-freq. capabilities which go all the way up to 37Khz, while the N802's only go up to 22Khz.
Both of which are absolutely irrelevant and meaningless.
Do not fall prey to the "specsmanship" games so beloved by the manufacturers. First, unless you're some sort of Guinness-worthy freak of nature, your ears top out at perhaps 18 KHz, max (probably more like 14-16 KHz, especially if you're over about 30 years old or have ever attended live rock concerts).
But ignoring that, odds are that both sets of numbers are more the figment of the ad copywriters' imaginations than the product of any reliable and reproducible testing. And further, even if by sheer chance there *is* some shred of factual basis for either claim, you have no idea if the speakers were measured in even remotely similar ways (which they near-certainly were not). And finally, even if by some miracle this specific comparison was even slightly meaningful, it would be utterly swamped by the much larger differences in the two speakers' sound elsewhere in the spectrum (especially in the midrange, which is *always* the most important part).
In short, you're obsessing about a non sequitur.
Both Speakers use a pair of 8" Woofers and the low-freq. are within 1hz of each other.
Also meaningless, for at least most of the same reasons (albeit, it's usually somewhat easier to make repeatable frequency-response measurements at the low end than at the top end; but still...).
Bottom Line: Get out there and *listen* to the speakers, preferably in the same room (with luck, one which closely resembles the room you'd be using them in) and with *your* music. That's the only way you'll ever know which one (if either) best suits your particular set of aural priorities.
