Well, my two cents:
The B&W 802II is a great choice, I agree! However, they do require substantial power, clean at that. With this said, the 805's for about $850 AND a Sunfire True sub (about $650-750) is EXTREMELY tought to beat AND the 805's do not require the power of the 802's!
You can substitute many subs to make up the lower end, but for a monitor, the 805's are tought to compete with. For what it is worth, I do LOVE the HALES REV ONES too!
Oh, if you have the power to run 802II then THE best speaker sub $2,000 (B&W 801M) is the Energy Veritas 1.8's!
IMHO
