anybody model or use the infinity reference 860s

[Jroo 10+ year member]

Since you cant really get the JBL GTO 804's, I was told the infinity are basically their little brother and sound quality is the same. Price is also right as 4 of these will run me under 200 bucks shipped. From memory I thought I remember being told that 4 infinity 860s work really well in a 1.3 sealed common chamber box? That sound correct or has anyone modeled and seen something different?

They work fine in that box with a bit of polyfill.

So 1.3 with polyfill or make the box bigger. I saw that .35 per sub is about Ideal so that places me at 1.4. Any benefit like gaining low end going any larger than 1.4?

not really, just however convenient it is for you. A sealed box is a sealed box. As long as you are not .5 cubic feet off, you should be fine.
