What a great speakers. But we must follow procedure. If so the sound is fabulous. First we should have wooden speaker chamber for 10mm speakers. We have to add just a bit of sponge inside and drill 1mm rear hole. Of course Aipinchun cable is a must. When assembled it is required about 10 hours of burn in the speakers at high volume. What sound comes out is amazing! Yeah, this is my second order. It tells it all.
Just OK , nothing special. You get what you pay for. I assume the designers should make very good sounding speakers. Anyways the built quality id great.
After 'burning in' speakers for ten hours on my player with high volume, the same speakers sound ten times better. The sound is very much improved. Maybe a high frequencies are somehow missing a bit. For the price we cannot find any better speakers that cost much more.
