beta 8a rising response?

AudioGeek · 27th April 2009, 08:02 PM

well i currently have a Alpha 15a / Fostex 167e OB combo.. nice really.

I want to double the Alpha 15a's per side and find a better midrange driver.

sooo.. either it is:

A) Beta 8a and a couple of BG Neo ribbons
B) Radian Co-Axial.

either way i was debating about a series crossover.

any thoughts?

Have a look at the Delta 8 from Emminence. Does have better spec, same power / efficiency and does not suffer from the ringing that the Beta 8 has. I am working on an EnABL process for the Beta 8, but have not yet solved the Raleigh waves that occur out between the rib and surround, that cause that ringing to occur.

Otherwise the Beta 8 is an impressive driver. I have heard them in Gary Pimm's large scale system and they do a fine job there.
