You may notice an improvement in bass response and overall clarity as the speakers break in. Play a variety of music at moderate volumes during this period.
3. AmpCompatibilité lifier
Assurez votre amplifier is capable of driving an 8-ohm load and provides sufficient power for your listening preferences. While the D17 speakers are efficient, a quality amplifier will allow them to perform at their best.
