Radian 5208c or GPA 212-8a?

AudioGeek · 22nd December 2011, 01:59 PM

Hey everyone!

So, as a show of hands if i wanted to do a simple ported speaker with one of these great co-axials, which one would be "better" and why?

Radian is cheaper i guess.

Also, the Radian I could do OB but not the GPA.

Finally, if i had them in a box, do they really need a BSC or should i just add a powered 12" to them?

Thanks!

You may have better luck posing this question on the multi-way forum as coax are not really full range drivers. While multiple drivers are sometimes used, most on this forum are opposed to a crossover in the voice frequency range of 300 to 4000 hz. which both of these drivers require. I have had Altec A7s (2 way) which cross at 500hz and 604s (coax) that cross at 1500 and I much prefer the A7s.

Another option if an 8" is suitable is the B&C 8CX21 which is about $US160 at PSS.

Whats the size of the enclosure. Are you using them as a low frequency driver also or do you plan the use of added subs?

Why are you comparing a 8" to a 12".

I was considering the 212 by GPA some time ago but couldn't seem to find anyone who had any experience using them, and only one that had heard them at that time etc..
