CASCADE TAPERED ARRAY
Place two driversnear eachother andinterference betweenthe twodrivers createsfrequency responseerrors
(called “comb filtering”)for off-axislisteners; peoplesitting orstanding offto theside ofthe roomwon’t hear
the same tonalbalance aslisteners whoare “on-axis”right inthe centerof thelistening area.Polk Audio
multi-driver speakers combatthis with“Cascade Tapered Array” crossovers.One driveris “crossedover”
at a lowerfrequency thanthe otherdriver, filtering out thefrequencies wherethe interferencewill occur(thereby
eliminating interference effects).The CascadeTapered DriverArrays inPolk LSiC, LSi9, LSi15 and LSi25 speakers
results in clearer, moredetailed soundand uniformtonal balancethroughout theroom. Thesound isconsistently
accurate whether thelistener isstanding orsitting, in-lineor off-axis.See moreabout CascadeTapered Driver
