Cornwall iv

Yes 60hz is probably good. Honestly most speakers start rolling down at 60hz and then they “crossover” with the port. I find speakers sound better if I crossover where the bass driver rolls down before the port is engaged. That has been my experience with a number of speakers.

the big 15” woofers with accordion surrounds are very good in the mid bass because they settle fast and have a ton of surface area but deep bass is not their strong-suit due to low travel.

JL is good about fixing subs ($550 for full rebuild out of warranty) but this is my 5th failure (4 prior rebuilds, 2 per sub) so I am done and moving on to another brand. 

I definitely noticed an uptick in the mid bass speed when I applied the crossover.  Very good improvement indeed. I need to get the wife and kid the hell away from me for a weekend so I can experiment!! lol. Prob not gonna happen anytime soon. Daddy daughter dance with my second grader Saturday night. Haha. 

Wow that sucks about your experience with JL! I had 10 years of trouble free service out of mine. Only had it back for a few months after the recap of the amp. Hoping it’s good to go for a while but yeah with your experience I would be done with them as well. 

Nice, Enjoy the time with the kids, they get big fast. Mine are in 1st grade and preschool.

The Cornwall was designed for "corner" or "wall" placement. Very easy to drive, until the divorce they were excellent R&R speakers. Everyone should own a set of horn speakers at least once on their journey. I've stumbled across little companies or individuals who offer upgrades for Klipsch horn speakers; there seems to be a little cottage industry in crossover mods and replacements, and drivers. I do not think your will regret grabbing these.
