I sent Clayton a great idea which anyone with a powered sub on their X3, X5 would appreciate.
The Burr Brown BB PGA2310 digitally-controlled precision attenuator is a very accurate cost effective way
To implement Bass volume adjustment ,and mute. My friend built a open baffle with a hypex amplifier
Within 2 weeks he built a little board with a sensor and $10 Phillips remote .since the speakers Xover is fully dialed in like the Spatial X5, X3. All that’s truly lacking is the Bass volume adjustment , for we all know Bass output can vary per recording , and to be able to adjust it on the fly would be fantastic . I just thoughtI would mention this
For my friend being a DIY electronics tech ,if he can implement it in 2 weeks part time and all the set up parameters are available on Burr Browns site . It would be a great refinement to a great speaker !! 👍
