I had Theatre 4's and then Pro's but with Altec 806A not JBL 2446. The JBL 2226 woofer is quite a bit more detailed and puts up a more "realistic" soundstage. The Altecs go a little higher, I think than the PSD-2002's and, again, allow more detail and air. That said, the Eminence Delta/PSD-2002 combo is very musical, dynamic and has great weight in the bass.
