We actually have (3) pairs of the JBL230s'. 2 pairs still brand new in boxes. Overall a nice sounding, flat response, but needs a
mild bottom-end kick... To sound right..
The Northridge series was enhanced by Dr.Toole's R&D team, also note there was a spin-off series using the same drivers/acoustics sold under the HK brand exclusively for Circuit City.
Just my $0.02...
