Oval shaped steel column We adopted an oval shaped steel column for the RSS-600. Squared or round shaped columns each have their own particular resonance nodes, but oval shaped columns do not. By using an oval shaped column, it is possible to eliminate this particular tone or coloration. The oval shaped steel column is harder then 2017S Duralumin or brass, so vibrations that reach the column will never go backwards into the top plate. Some other speaker stands’ columns are made from Magnesium which is said have a high inside loss rate and high vibration absorption characteristic. Materials which are said to have high inside loss rate do not have superb absorption capabilities. Also some stands adopt soft materials for the column like magnesium and use harder materials for top plate such as aluminum or steel. But this causes the vibration to remain in the top plate. Even if it reaches the column, it will be forced backwards into the speaker. This leads to a reinforcement of resonance and coloration. Some manufacturers claim these resonances and colorations represent a high resolution sound, but this is not correct.
Tourmaline & Polypropylene - mixed special particles The oval shaped column is filled with tourmaline powder and polypropylene particles. Vibrations from the top plate reach the column and get converted into heat and are eliminated very quickly by this special filler. You can experience the vibration absorbing effect by moving your hand from the top to the bottom of the column. You can feel that the vibrations gets weaker as you slide your hand towards the bottom. Also polypropylene itself is oval shaped and very light weight. By combining it with tourmaline powder it becomes a material which does not add any coloration to the sound. The filling in the column determines the sound quality of the stand. The RSS-600 column is filled up completely to eliminate standing waves and resonance generated tones. ACOUSTIC REVIVE`s speaker stand is shipped completely assembled so the customer does not need to deal with the filler material. Many speaker stands require assembly, and typically the dealer will have to add an extra charge to assemble them for the customer.
Other speaker stand columns are not filled up completely, and the manufacturers claim that they are adjusting the amount of the filler to control the tone. But this only adds the resonance tone of the stand to the speaker, which will obscure the real tone and performance of the speaker.
