Yes I have....dealer as well. Excellent build.....Im using the 10" side woofer bi-amped to seperate amp and active x-over. It was okay...not good, but okay. I removed the woofer and wired it direct to the binding posts. Removing the NHT x-over all together. Now thats the way the speaker should sound. Night and day difference. Solid, fast, tight bass. Also have better control over the bass section. I would have to say the the Classic sound is different from other NHT's have had or listened to. Not as bright as the ST-4. Smoother.
