If you want Tab 10's then listen to them only because as a sealed box design in the tradition of an LS3/5a they do not sound remotely similar to all the rest of the older reflex-ported Tablettes. I had Tab 10 Sigs briefly and found them to have an explicit mid-band and sweet treble but no bass. I tried them in several rooms, on several amps, close to and away from walls but could not get any meaningful bass out of them that I was used to with the Tab 50 Sigs.
