5" speaker option

I found a brand new 5" speaker that is quite good. Polk Audio DB501.

Look Here

I got them for $40 and sound fantastic too. The bolt in place perfectly with no modifications required.

 

I knew I could find some 5 inchers to not have to mod the speaker box at all.

 

I actually got them from amazon about 2 months ago. They had some factory refurbished ones for that price. They are quite nice. Nice specs on them too. Polk makes quality speakers!
