RobertR Posted April 28, 2013 Report Share Posted April 28, 2013 getting ready to re cone my sa-12's from d4 to d2 and Im trying to decide if I should go ahead and pay for the spl coils. How much louder are they? How much sound quality will I loose with the spl coils? Some people say they will get loud but sound like garbage. Others say they dont really sound that bad. Any thoughts?

SnowDrifter Posted April 28, 2013 Report Share Posted April 28, 2013 Isn't the spl coil a shorter wind height?

audiofanaticz Posted April 28, 2013 Report Share Posted April 28, 2013 From Jacob: The SA-10/12/15 SPL coil is simply an 8-layer flat aluminum USA made coil -- temperature handling is much higher.Raises the FS of the woofer; hence being labelled the SPL coil.They are fine for daily but have less bottom end and are ONLY sold on re-cones.The SA-8 has an SPL coil in D2 / D4 that is also okay for daily -- it's simply a 4-layer CCAW coil to drop mass... the D1 SPL coil is for burps only (very tight) and is an 8-layer flat as well.

RobertR Posted April 28, 2013 Author Report Share Posted April 28, 2013 any idea how high the spl coil raises the FS? all thing being equal...... how much could I expect to gain from spl coils over the standard coil?
