Didn't replace them, just needed funds. The N2X are the speaker that got me hooked on upgrading so much last year...before them, the differences between speakers I'd heard (of those I could afford) were quite minimal except in voicing. The N2X simply blew away anything I'd heard under $2,000. I now have OB7s and Gedlee Abbeys, of course

The N2X is reaally close to the OB7 sound and with those PE cabinets can be built for next to nothing. Or using the DIYspeaker cabinet guy (quite inexpensive).
I would love to get Danny to build me out an ultimate 2-way with a RAAL tweeter as soon as funds allow and he's up for it.
