Tested with sine generator at 8, 10, 12, 14kHz, clean sound. Haven't tested with music yet. They look good, well made. Communication with the seller is excellent.
Very nice Speaker, fast delivery to Italy, arrived in perfect conditions thanks to the great packaging made by the seller. I can't say how it works for now, bu I'll add new comments when I'll realize teh sound box!! Absolutely suggested seller.....great work!!!!
My personal installation in the hand made enclosures applied in a dry wall above my bed....I'm really happy for the result!!!!!
