Extremely loud and great for turntables if you want a quick and easy setup with these active speakers running from your built-in preamp turntables. Bluetooth is great and the overall sound quality is also rich, bass hits hard when it wants and synth notes are amazing, such a rich and clean sound. I recommend either using them for vinyl or using them for the easy Bluetooth convenience. Definitely recommend!

Sound is Great. That's it. Will be much better when I can place the speakers a bit further apart and a bit further away from my turntable. What is it with you people..... just a little bit more speaker cable and longer RCA cable will make life so much easier. You call them Bookshelf speakers... How many bookshelves are over 30cm/12inches deep ... Your user manual states 240 deep... what about the extra 50mm plus to connect cables.. what about an extra 100mm to get your hand behind speaker to turn on or off or to change mode.
