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.
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...
