The "subwoofer" appellation invites a harder look at how high it'll play gracefully. The spec sheet suggests it turns nasty above 1 kHz, but the only way to know for sure is to try it....
Probably. Looking back, I only measured them nearfield; once I determined that their allgededly excellent bass response was fiction, and knowing that I was upgrading the tweeter to a waveguide, I didn't need to know anything about the high end.yeah i noticed that. how high does the stock klh driver go to? A guy in the other thread said 1500 hz. is this correct?

Note that there's no lowpass on the woofer in the stock crossover. Whatever you use, you're likely going to have to shut down any modern woofer's high end. You can see in the sim @ #182, above, what the highpass looks like, electrically....
From my measurements, they certainly do not live up to the hype, and I've looked at two pair now.The drivers just seem junky and the response seems to be mostly mid, the high and low is kind of lacking.

I struggled to keep them closed-box. Your assignment, should you choose to accept it, is to find a modern woofer that'll work worth a whit in that alignment to provide extended bass; the original certainly didn't....Ports and fiberglass don't make sense though...
That one is noted for tubby bass. To double-check, try at least one different amp.
Trying to make a KLH17 (or in my case, a 20) into something it isn't can be fun. But reflect; just what the hail is it? As is?
