Quatro Wood best feet

zee that is the one! 9v battery required

yes you need the RS Analog , the Vandertones are calibrated to that
it should be $30-$40 on ebay

@zensview you can download Vandertones at Vandersteen website
burn a CD or play thru streamer
use caution
i also assume you have the Radio Shack Analog SPL meter ?
what amp are you using ?
need to verify input impedance to properly set the M5-HP crossover

I steered you wrong
service via Factory, parts via your dealer
sorry about that!

One thing to understand is that most all Vandersteen feature cabinet within a cabinet construction WITH a proprietary constrained layer damping between cabinets, so the cabinet is not vibrating a lot.
RV is data driven and the 7 cabinet is his reference which adds an autoclave cured carbon fiber wrap to the above mentioned construction- the Treo is remarkably inert and weighs 85#, Quattro even more massively constructed!
try them out with factory spikes, shoes
try them out
get a baseline
then try other products
hard to beat the Amazon return policy

Yes they stock them
i have them under both my Treo and 7 with hardwood floors
jaclyn in parts can get them out to you

Start with the Vandersteen spike shoes, machined Aluminum cups the spike fit into
they have a felt pad to protect your tile.
they will also preserve the geometric relationship in the manual for tilt, ear height, distance to speaker.
iMO start there. Award winning sound possible that way.....
