Big Below 15k used that can play loud as heck

Also, very respected agon member here w B and W successfully integrated Tekton Sub driver towers, they are 10” pro / musical instrument divers in a tall array cabinet

Tim is not prone to over the top fanboy hyperbole and might be able to provide insight… @boxer12 , IF you go that route, i would definitely reinforce the factory Tekton box as it is much much less inert than your excellent B and W cabinet… 

Full disclosure, I have not heard Tim’s system, but given his wide ranging exoerience w Wilson to B and W and much more, I trust him.

At the volume levels you mention which your stated amps should be loafing at, i suspect you are listening in a deep cancellation standing wave trough…. need to move chair, speakers, sub, all three. ….  How far are the B and W from the reinforcing back wall ?  Are you low passing the B and W into the subs ? Try running them full range. Best to you.

Jim

Well you already have subs….so you need mid bass slam….nothing does that at concert levels like separate towers of 10” drivers in an inert cabinet, preferably servo. Meyer ain’t close to your budget, i know…i spec them for people who make a living w them.  Pro gear good advice, start shopping reverb, etc…
