If you bought two new Vandy Sub 3's, yes, it would bring the price very close to the Quatro. If you don't mind giving up the freq. EQ. of the Sub 3's, you can buy 2 used Vandy 2Wq's which you can improve the sound of the Treo immensely. I as some others have used this combo with great results. If you look around and are patient, you could pick up a couple of used 2Wq's for $1200-$1400 in very good condition. Just an option to consider.
