Would spikes help me?

Didn't Tyler supply spikes? The spikes for my speakers were in the base at the bottom which is removable, but then these are not the PD series. Give Ty a call. FWIW spikes thru carpet to the floor will give you at least a more secure foundation for the speaker if you use 4 spikes. Three spikes can make a tall speaker a bit tipsy. Whether you will hear a difference depends........

Ty doesn't supply spikes for the PD80s. He didn't want to add more height to the horn. Maybe I'll add spikes to my couch to make up for it.

One thing's for sure, they'd be nasty to move around with spikes on.

Audio Points.

What you should hear is potentially little or no difference for the first 8 days or so.

But what you will hear after this settling in period is extended highs with a more natural extended decay and increased speed and dynamics. You should also hear a deeper more defined and controlled bass. Moreover, you should hear a deeper and wider soundstage with better imaging and transparency.

Newbee has a point about the 4 points for safety, but 4 points are also a great potential for compromising sonic improvements of using products like Audio Points.

3 points make a plane and provide the best method for coupling the speaking to the subflooring system.

4 points create uneven rocking scenario and greater difficulty for properly coupling to the floor.

-IMO

Thanks very much guys, I think I'll go for it!

At 230#, spikes will add little to the sonic picture imo. I doubt Ty is selling hernia insurance. Lift with your legs!
