I replaced the OEM spikes from Polk with some brass spikes from Brass and Granite Audio. I figured I would give these a shot at least for the looks over the plastic ones. I was surprised at the end result, they definitely allow more room for placement. I placed the 1.5" spikes in the rear and the 2.10" spikes in the front which sort of angled the 12s up just a tad. These do allow you to adjust them even more. So I was able to get the tweeter just right; aimed right between both rows of my H/T seating. Anyway, thought I would share. A worthy buy as they make the speakers look even better. Anyone interested Polk threads are 1/4-20.

How did it change the sound ? Post some pics. I added myespikes to my SDA-1Cs and agree that make the speaker look better but there was a noticable improvement is the bass. Much tighter and defined.

BTW, nice HT, clean install !

I will try to take a few snapshots before I fly. Overall the SQ improved in my second row of seating. More detailed in sound as I can actually angle the speaker more in between the seating positions if that make sense. And thanks for the compliment bro.

kewl, tweaks like this are fun. I think you are the guy who works for JD, ever heard of the Mid-West Old Threshers and Timers reunion in Mt Pleasant Iowa ?

I love the popping Johnnys. I have a couple of Fairbanks Morris stationary motors and Maytags.
