simply physics tonecones molded from polypropylene ppn with replaceable aluminum tips these cones are far more inert than an all metal design more attractive and they won t corrode the largest size tone cone features a hollow spoked body which can be filled with your choice of damping material or simply physics molded santoprene insert material the large 2 h by 1.5 d hollow tone cones and the medium size cone 1.5 x 1 feature aluminum tips and are drilled to accept the optional 1/4 20 machine thread studs so that you may attach these cones securely to your speakers and turntables i can provide matching brass female threaded inserts which can be installed in the base of your speakers or turntable plinth with an absolutely flush neat fit you need only drill a 5/16 hole 1/2 deep and press or hammer the insert into place also available is a small 1/2 high by 1.5 diameter all ppn tone cone with large 2 tone cone with 1/4­20 stud $9.00 large cone w/santoprene inserts and stud $13.75 medium 1.5 tone cone with 1/4­20 stud $7.50 small .5 plain tone cone without stud $4.50 small tone cone with 1/4­20 stud $5.00 optional 1/4-20 stud which can be used on its own or in combination with the simply physics isopod the isopods are 21/2 diameter by 1 thick vinylex feet which have a cutout sized to receive the small tone cone or tone cup in its base this combination is known as a cone couple shown here and is simply physics ultimate isolation product for use under audio electronics if you need to protect your floor or furniture from the sharp point of your cones tone cups are available 1.5 diameter ppn or aluminum pucks with a conical depression in which to rest the cone point using the isopod/cone cup version of the cone couple underneath a component that is perched on tone cones will provide a very high degree of isolation with great rigidity for tightly controlled deep bass performance and razor sharp imaging protective polypropylene tone cup $4.00 plain aluminum tone cup $6.50 isopod/small tone cone cone couple $13.50 isopod/cone cup cone couple $13.50 isopod only $9.50 1/4­20 female brass threaded insert 50¢ thread adaptors converts all cones that accept a 1/4-20 stud to either 10-32 5/16-18 3/8-16 6mm or 8mm thread $6.80/4 pcs simply physics v2 decoupler the ultimate height adjustable isolation foot comprised of four parts a female threaded polypropylene cup male threaded aluminum alloy foot brass lock ring and replaceable aluminum or heat treated stainless tip these are height adjustable and available in two sizes v2 and v2 jr the v2 size which has a 2 diameter polypropylene cup adjusts overall foot height from 3 3.5 and the smaller 1.25 diameter v2 jr adjusts height from 2.35 2.65 the polypropylene cup is attached to the component with a bolt and washer or threaded fastener to 1/2 d for v2 to 3/8 for v2 jr of your choice the polypropylene cups are black and the feet clear anodized black anodizing add $6 each and heat treated stainless points add $20 each are available options at additional cost presently i stock the v2 jr with the larger v2 feet available as required on a special order basis with approximately a 10 day lead time v2 jr decoupler $45.00 each v2 decoupler $75.00 each machined ppn cap is attached with appropriate thread bolt and washer to component and is internally threaded for alloy foot allowing height adjustment brass locking ring locks alloy foot to delrin cup for maximum rigidity alloy foot is threaded to mate ppn cup and is knurled for easy adjustment replaceable aluminum tip or optional heat treated stainless at extra cost vibrapod isolators polymer cones and isolation cups for use under electronic components and speakers the cups come in five weight ranges #1 for 2-3 pounds per isolator #2 for 4-8 pounds per isolator #3 for 8-12 pounds per isolator #4 for 14-18 pounds per isolator #5 for 22-28 pounds per isolator all are 2.5 diameter x 9/16 high the cones are 1.6 diameter x 1.0 high vibrapod isolators specify $20.00/set of four vibrapod cones $6.95 each iso-bearing support globes uniquely shaped isolation feet for audio components each iso-bearing is a sphere of vibration absorbing elastomer material cradled in a delrin cup which in turn rests on a thin mat of the same elastomer material as the sphere itself the cups for the larger feet shown are trimmed in polished brass the elastomer material used is rather dense exhibits almost no rebound and is extremely inert these are one of the most effective isolation foot designs available exhibiting both reasonable rigidity and a very high damping factor the round shape dissipates foculpods from spectra dynamics dark grey hemispherical feet formed from the same advanced low resilience polymer as their other products with exceptional shock absorbing properties each foot is 2 in diameter and just over 3/4 thick the maximum suggested load is five pounds per pod and it is recommended that you use four underneath each comenergy with greater efficiency than more conventional designs small size suitable for loads up to 4.5 pounds per globe 1 sphere in a 1.4 cup 1.2 overall height large size appropriate for loads up to 17 pounds per globe 1.3 sphere in a 2.0 cup 1.7 overall height large iso-bearing out of stock for now small iso-bearing $19.95 each ponent excellent beneath cd players preamps or any component that is vibration sensitive our current favorite soft foot and the most cost effective ask each new polipods in appearance just like a small foculpod 1.5 d and just 1/2 thick use for lighter loads where a thinner foot is required ask each aq sorbogel feet these sorbothane hemispheres provide a highly damped medium to isolate your components from vibration sorbothane feet are useful in many non audio applications as well underneath typewriters computer cpu any vibrating or vibration sensitive equipment available in two sizes large are hemispherical 1.2 thick by 2.5 diameter 10 lb load per foot special price $39.95/four also one set/four older hockey puck shape feet 29.00 spike feet an effective but economical choice for use beneath speakers especially on thick carpet where a cone type foot won t penetrate to flooring below small 1.50 l x 5/32 d steel spikes .5 of it has 1/4-20 thread supplied with nuts and .5 long press type female threaded brass inserts $5.00/four large 2.50 l x 1/4 d steel spikes 1 of it has 3/8-16 thread supplied with nuts and 1 long screw in type female brass inserts $7.50/four also available is an import gold plated .80 h x 1 d
