[QUOTE="audioholic, post: 7493927, member: 549629"] I understand. You said it yourself, you've never heard a good bandpass setup. They are out there, and they can sound very good. When done right, they will produce less audible noise than a traditional box design. The bandpass function of the enclosure tends to filter out a lot of distortion in the upper range, and the sub is buried inside the box which makes for less mechanical noise. And contrary to what you believe, they are more efficient than traditional box designs. You can just tighten up the passband on your xover with your sealed or ported box, and get the same efficiency a BP enclosure offers. True, this efficiency comes at the price of a more limited passband. Even with well designed BP enclosures, the narrower passband tends to create a hole in the midbass region, and the added efficiency makes for a greater difference in output potential between the sub system and the weaker front stage, for most people's unbalanced stereos. But you cant blame poor implementation on the enclosure design. With a strong front stage, strong up-front midbass, and good tuning, a system using a BP enclosure can sound very very good. And that's not even mentioning all the poorly designed pre-fab BP boxes out there giving the design type a bad reputation. Its not easy to do a BP setup well. But when you nail it, you'll have a very low distortion sub setup that flexes your eardrums accurately and effortlessly. [/QUOTE]
