    Thin film sound that is amazing!

    These speakers are just amazing. Highs that I never heard before with my prior system just jump out at you. You’ll need to pair these with a sub as the bass is a bit weak, but why would you not have a sub anyway???

    One you hear an electrostat, you will want them

    Simply the best speaker I purchased to date. It's fast, articulate and looks good on the wall. Electrostats have a sound signature that is unique to them and I love it.
