WAF….. Woofer Acceptance Factor ?….. you really should join the Vandy forum…. lots of integrated amp owners with appropriate filter caps installed in various mfr. amplifiers….. have fun, explore….
My Moon 700i is an integrated and does not have the ability to place the vandy hi-pass filter in between the pre and amp. Also, my WAF with these speakers is lower because of the bass they already produce. I am certain the Sub 3 would clean up the bass and improve the sound.
Sure… a Sub 3 is a very unique Vandersteen subwoofer w 11 bands of EQ to address room node issues which allows you great bass AND the flexibility to place your mains ( in your case Treo ) for best imaging. The high pass filters greatly reduce to bass load on your main amp and Treo increase in midrange clarity. You can see a Treo CT / Sub 3 system on my Casa Pacifica system page.
Enjoy the Treo a very musical speaker. Consider joining the Vandersteen owners forum. A fantastic upgrade for your Treo is the matching sub 3 and high pass filters… it’s way more than better and deeper bass as it yields even better midrange.
If you are by Audio Connection in Verona NJ we will be working with them with our new preamps and amplifiers. Oure recent demonstration there on the Quattro's was mid blowing. Call and ask John.
