"-blu tack to decouple speakers from the top plate of speaker stands" then why bother with the speaker spikes?!!!!!!!!!!!!!!!!!!!!!!! The real purpose of speaker spikes is to couple the body of the speaker to the floor. Speaker Spikes/Cones are not intended to isolate as those used under equipment (which Ill get to later). Spikes/Cones on stands/speakers are intended to pierce the carpet to couple the speaker to the floor. Newton's Law is the reason for spikes on speakers. The idea is to prevent the speaker from moving forward and backward on the carpet or flooring because of the forces created by drive movement. Which is the reason most people hear more clarity and a less muddy bass when using spikes/cones. The drivers cabinet is being securely held and coupled to the floor minimizing speaker movement, which in turn reduces unwanted out of phase byproducts caused by unwanted movement. Remember your speaker is an active driver system which is moving air and there are many mechanical forces at work. If speakers were not meant to be hard coupled to the floor, the manufactures would have designed a suspension system similar to turntables to hold the speakers so that they might move freely in space (which would be a disaster as far as sound reproduction is concerned). It takes vibration to even make sound and the idea behind speaker spikes/cones is to create a solid and stable foundation from which to project those vibrations without adding additional products from the cabinets movement. What good is the latest stiffest non-resonant driver mounting baffle if the cabinet itself is moving back and forth? If one wises to get the most out of ones spikes/cones, dont use any product between stand/cone/spike and speaker. The idea is to have the best mechanical connection possible. Of course there are small exceptions to this, but they mainly have to do with personal taste of what sounds good to a specific individual. On equipment, rubber or similar material has been proven with an accelerometer time and time again to reduce the most vibration and provide some of the best feet as well as most economical. An accelerometer shows a large increase in vibration when cones are placed under equipment. One theory is that most equipment doesnt have enough mass to make the spikes dig in and that the proper shelf material is not under most spike equipped components. Now this in no way discounts what can be under non-spiked feet. A 30 pound slab of granite with an amp with rubber feet is a very stable arrangement for an amp. -- iPhone *iPhone* 'Last.FM' (http://www.last.fm/user/mephone) Media Room: Transporter, VTL TL-6.5 Signature Pre-Amp, Ayre MX-R Mono's, Vandersteen Quatro, VeraStarr 6.4SE 6-channel Amp, VCC-5 Reference Center, four VSM-1 Signatures, Runco RS 900 CineWide AutoScope 2.35:1 Living Room: Duet, ADCOM GTP-870HD, Cinepro 3K6SE III Gold, Vandersteen Model 3A Signature, Two 2Wq subs, VCC-2, Two VSM-1 Kitchen: Squeezebox BOOM Bedroom: SB3, GFR-700HD, Thiel 2.3, Second Boom Home Office: SB3, NAD C370, two VSM-1 Home Gym: SB3, Parasound Vamp v.3, Thiel PowerPoint 1.2 Mobile: SB3, Audioengine A5 ------------------------------------------------------------------------ iPhone's Profile: http://forums.slimdevices.com/member.php?userid=13622 View this thread: http://forums.slimdevices.com/showthread.php?t=59052
