I need it, but my wife has a different opinion.You know you want a subwoofer. Subwoofers are like chocolate and fries: everyone likes them.
I have the 8030, so I'll have to do it by hand with something like the minidsp umik and REW. I didn't think the SAM speakers plus the GLM was worth the price difference, and I couldn't afford it anywayIf you already have Genelec´s calibration microphone, it´s just an extension and you´ll integrate it quite well.
