Loose vs stiff suspension


Recommended Posts

So what’s the pros and cons of stiff vs loose suspension? I have 3 15” Fi with loose suspension but thinking about reconing to change load.  I don’t compete but always ran loose and I’m trying to hit 150+  I ran 2 at .5 clamped around 4500 watts or so but they got stanky would stiff help handle the power if I’m in between max and rms?

Max watts is a imaginary number but stiff suspension would change your fs

Suspension nor the size of the motor, projects at all to thermal capacity of a coil.


I like loose. Loose will have a lower FS. If your competing, want maximum on a tone/burp, and play one frequency, then a tight suspension (when you put a ton of power at a desired frequency, and enclosure tuning, where the driver moves the LEAST) is desired.

I prefer a looser, broke in suspension for my daily ground pounders. 


Another edit- Just a personal post, but, i had Fi sp4s long ago. And adored those drivers. Beat on them for many many seasons. Soft spot in my heart for those drivers.
