This
mo-tion of the speaker causes a loss of musical inlormatior and reduces the c arity of ihe mLrs c'
ln order to ; iminate th s effect THIEL speakers can be used with stab lizer plns. The stabillzer
pins, either ol

The lirst lactor s the most d fl cuit to analyze or oblectrve y deterrnine. There are differenl ideas about what rs
