Saw a pair of the JBL ARC70 sitting in someone’s basement doing nothing.
Not appropriate to ask for a test.
Does anyone have any experience with these speakers?
Is it appropriate for HT setup?
Any suitable matching center speaker?
The Arc series will be decent - they are one level up from entry level,
however still lower than the L and Studio series.
The Arc is rebranded from their former LX series.
If you can get a decent price, then they will be nice - they were before the
true timbre center channels - however, look for a center with a 1" titanium
dome tweeter, it should work close enough.
