Dear NE, thanks for the fantastic job you did on rebuilding my KLH 5 crossovers. They look brand new. I received my crossovers in good condition and installed them today. I’m very satisfied. My fortes sound much better now. I finished the install today. Long wait but OMG what a difference! You have my 5 stars. Installed the crossovers over the weekend. You restored the upper range frequency response. The speakers now sound incredible! These crossovers are a significant improvement! Better stereo imaging, clearer distinctions between instruments and vocals and a more responsive bass. Got them yesterday and we spent today getting them installed.. I cried when we turned back on – the sound is so much better. Thank you You do wonderful work!
