My friend is sending me 8 full range faitals drivers 3 inch to try out in my system
I will hook them up to replace the Beyma and PRV drivers to see if I prefer them

Interesting.
How will you be arranging them? Two forward facing and two rearwards per speaker?

Excellent John. Have you moved house?   |

8 x 3" drivers will give you a surface area of 56"2
Your 2 x 15" drivers (ignoring the 2nd driver in parallel) have a surface area of 353"2 in comparison.
You will inevitably suffer from lower bass radiating area. How it will sound will depend on how you arrange them.

You'll be keeping the big boy bass drivers in, surely?

The bass setup remains the same....the array of 3 and 4 inch units look impressive! I need to get to hear these..

I am definitely keeping the Neo bass drivers in place
If I like I will think about adding a cap on the monoblocs to limit the bass output but we see
Vic really likes what the drivers do Good clean extended treble with more air and transparency
If I like I probably go 4 inch

They will be forward facing

They will not take up a lot of space Jules

It's a experiment no radical changes yet

Ah ok, I thought the bass drivers were Beyma.
|

Post by John on Apr 23, 2020 12:40:53 GMT
Both the Beyma and PRV are very similar in Specs The Beyma having better treble and the PRV better mid punch Combined together I get the best of both worlds
The Selenium Neos are the bass drivers

I would be interested in trying some Daytons 385 or 390 sometime instead of the Neos

Interesting. What would the efficiency of the array be?

They are a lot cheaper than the PRV and Beyma drivers and have better treble and fewer spikes in the frequency response graph

I wired in the drivers I had to adjust the bass amplifier to match
Initial impressions more atmospheric but I am missing a bit of warmth and depth
I add a picture later
