我 send email 問 Ken Sir (Ken Kreisel) 可否用超低頻 soundtrack (20 Hz) 嚟煲 KK MX-5000 MKIII,以下喺佢嘅答覆
"Yes, playing 20Hz, or other low frequency information will improve the sound your MX-5000 Mk3 a lot. Don't worry about breaking anything in the woofer. You should be able to turn it up load with no problem. You might smell a little burning smell as the woofer heats up for the first time, but that is OK. A frequency sweep from say 10Hz to 100Hz is the best, but it will be very load in the room."
