Smear is a result of artefacts replicated in both channels which are perceived to be in the middle causing the stereo image to collapse. The IsoAcoustics isolators reduce internal reflections to eliminate smear. The result is an improved stereo image of natural spatial sound.Dial In Your AngleThe IsoAcoustics Aperta speaker isolation stands feature a unique integrated tilt adjustment that enables the user to dial-in the optimum tilt angle with fine gradation markings provided to ensure the precision of the angle adjustments. The built-in tilt adjustment can be dialed-in 6.5 degrees upwards and downwards to optimize your speaker placement and focus.What's in the BoxAperta Speaker Isolation Stand - PairSpecificationsDimensions (W x H x D): 6.1″ x 3” x 7.5″Tilt: Up to 6.5 degreesWeight Limit: 35lbs (15.9kg)Quantity: 2 Stands (1 pair)
