What Do You Think . . . and How Does It Work?

Duke, very good of you to take the high road. You are a good man and above this nonsense.

I have built the Plutos, LXminis, and the 521-4s. Love them! The Plutos & Lxminis will "disappear" in the room. The tweeters for the Plutos are getting hard to find (I understand) but Madisound will have them if anyone does, also the complete kits. The LXminis are better, but use an electronic crossover and four channels of amplification, and so are more expensive to build. A subwoofer is a nice addition, but not absolutely necessary. People who haven't built them or heard them scoff; don't believe nonsense from uninformed and inexperienced naysayers.You are going to stuff the plastic pipes with absorbent materials (or old sweaters) and they don't ring. You can even build a subwoofer using the cardboard tubes used to make concrete columns. Be sure to build the recommended crossovers for the Plutos as they tame a peak around 10k.
The only negative is that they produce a small "sound front" (as do all small speakers) but the upward facing woofers get their sound spread out by the tweeter tubes and sound much bigger than they look. They are super cost effective! Build them! Do it! They are very easy to build.

Beautiful explanation of the benefit and implementation of the "pipe"

kenjit,

You might have not asked for an evaluation, but your behavior begs for it.

@glupson

There is no behavior you can discern on an internet forum especially when I only talk about speakers on here. Dukes technique has been to try to discredit everything i say by accusing me of narcissism all the while ignoring the topic being discussed.
Whats the name for that? There must be an illness that corresponds to no?
