training ears to like cheap drivers versus Fostex? - Page 4

Scottmoose · 09:41 AM

FWIW, applying good old Newtonian physics, below are the potential maximum acceleration factors of the Fostex FF85K & FF125K drivers in ms^2.A^1. Theoretically, the VC & cone of the 125 can accelerate at only about 78% at the rate that of the little 85.

FF85K = 2405.556
FF125K = 1872.647

(Edit: just to stress I am not saying this is anything to do with transient response; all wide band drivers have good transient response or they wouldn't be wide-band drivers. What it does tend to give is an indication as to the resolving power / detail of a drive-unit, all other things being ~equal. Not to be taken too seriously, esp. when not comparing like against like, but it's still useful if used sensibly.)

I guess an example of not noticing wear out would be like your fluorescent light bulbs getting dimmer and dimmer. You don't notice it until they go completely out and replace them with new brighter bulbs.
As Planet 10 says it takes a long time for vintage speakers to wearout. I run across a lot of old speakers that have been partially eaten by insects.

With vintage speakers there is also the fact, that the ones that have completely worn out have already found their way to the tip.

>>> also having a system that is wonderful on certain kinds of music, you'll tend to hear to those genres more and more, thinking the system is wonderfull more and more...

Interesting comment and observation. I would have to agree. I also think finding good qualities in inexpensive drivers is always possible making them enjoyable.

Vintage drivers. I have just put 2 Goodmans Axiom 300s in cabinets and I like the sound. The Alnico magnets must have lost a bit but the sensitivity is right up there. I guess I don't have to worry about breakin with these babies.
Anyone else had any experience with this driver? Even though it has faults it does some things I really like esp on female vocals, maybe it is the Alnico thing, it doesn't go to pieces on loud sustained notes.
