[QUOTE="PV Audio, post: 6436211, member: 554493"] It won't even be close. The sonys have less than 25% more cone area as it is, and assuming 3db is gained from porting, they still won't be close due to the Vd, which if someone doesn't know is Sd*Xmax (cone area x stroke). The W7 has many MANY times more Xmax than the sonys will have. That speaker moves over 30mm one-way, while the xplods might manage 10. This really isn't even a contest. [/QUOTE]
