HELIOS Speaker Kit

Mijostyn you are beginning to sound a bit rude and boring.  Would it make you feel special to tell me my lunch doesn't taste good, hahaha!!!

We are saying the speakers sound great, and you are saying they are croaking, yet you have not heard them.

The designer had extensive experience designing speakers and provided the designs at no charge.  He wrote that the distortion on these was so low it was difficult to measure at normal volumes.  In fact, the lowest he has ever measured.  He said this speaker design may have been the best he ever built.

The manufacturer, SB Acoustics, asked him to make this design for an audio show and it received a lot of positive feedback.  One of the reasons I purchased the kit - all the comments I read from people who heard the speaker, not one said it was "ok", "not too bad", but every comment used words like "amazing" and "best ".

Jeff Bagby was one of the most talented speaker designers to ever hit the DIY community.  All of his designs have been carefully thought out and perform very well--both by ear and by measurements.

To say that "he has no idea what he is talking about which means he has no idea how to design a loudspeaker" is shameful and uninformed.  

@gabrittain  what is your point to post this?  if you had to summarize in your own words what is your opinion of the doppler distortion articles, posts, opinions, actual audibility ?

Regarding the Beryllium tweeter, Beryllium is a highly efficient material that can be used for speaker diaphragms. Beryllium tweeters are known for their clarity and detail, but they can also be harsh-sounding vampire survivors if not integrated properly into the speaker.
