Went in this shop on walzem guy didnt know nothing about speakers at all. Not even the slightest info. His common response was ..idk....went to san pedro and tried to pick there brains before i let them install my $5000 system. The manager has no good custermor service just mumbling higher prices than the tech was offering. Acting as if i was clueless to wat i needed they tried selling me way more than i needed and ended up with a $1200 bid just to install. Guessing they felt i had more money because of my system. All tgey had to dowas install i had everything no way ill pay 1200
