Sub help
 

Ok so i got rid of my sony xplod 12 inchers (yay) and now have 2 Phoenix Gold XS84 svc 8 inchers N.O.S and the site says .17 cuft for spl and .25 for normal/spl is that gonna sound ok i am runnin a reg cab truck and gonna put them between the bucket seats i just installed any tips on makin them sound really good i used to have 2 8 inch mtx in my chevette and they were loud and i loved them any help thanx alot

The PG XS drivers as with the Xmax series of the same era published box specs were way smaller than optimal.

I would suggest 0.5net per 8".

hey thanks man do you know how to fugure out the driver displacement by chance?

Sorry dude. I kept the paperwork I had for the XMAX series but tossed the XS stuff as I was never really much of a fan of them (for the money in that era the Pioneer TS-W1200C/1000C were better performers and cost about the same so I sold many more of them).

The only specs I have left on the XS84 are:

34-1kHz freq res
150rms continuous
300 peak power handling
3.875" mounting depth
7.375" mounting diameter
16.5mm Xmax peak to peak
86dB sensitivity
1.5" voice coil
30oz magnet
0.4net sealed
0.7net vented

Again I would suggest the 0.5net design if you're going sealed though. Good luck!

Hey man its all good thanx a ton you have helped me out immensly

oh and i will go with the .5 net you said
