王老说是Small 提出的EBP指标,当EBP<=50适合作闭箱,EBP>100适合作开口箱;
以下是Bassbox 软件的推荐:
Typical Characteristics of a Closed Box Woofer
• Qts greater than 0.3.
• Low resonance (Fs). High moving mass (Mms) and compliance (Vas, Cms).
• Large Xmax (small woofers: 2-4 mm; large woofers: 5-8 mm).
• Moderately strong motor (BL).
• EBP less than or equal to 50.
Typical Characteristics of a Vented Box Woofer
• Qts from 0.2 to 0.5.
• Moderate resonance (Fs) and moving mass (Mms).
• High compliance (Vas, Cms) is not necessary but can be beneficial.
• Moderate Xmax (small woofers: < 2 mm; large woofers: < 5 mm).
• Strong motor (BL).
• EBP greater than or equal to 100.
• Avoid woofers with excessive unknown losses.

答非所问。
初哥说的是“道理在哪里？”要的是原理。
“某某人说”，“某某软件推荐”，都决不是原理。
