HELIOS Speaker Kit


Has anyone heard the Helios speakers?  by Jeff Bagby and Javad Shadzi?  if so can you talk about your impressions?  I am sure it is a great speaker, but i want to make sure that midrange, vocals would not be a weak point - because the speaker has a huge 9.5 inch woofer.  Second question - anybody heard a Beryllium tweeter before?  I want to make sure these are not too harsh?   Thank you for your comments...

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.
