Infinity cs 3009


Brand new here.  Does anyone have any knowledge on cabinet specifications or have technical input for Infinity cs 3009?   I am thinking about actually trying to build a pair, or at least something comparable or better than these. Heard us at years ago and loved them and now I cannot seem to find any to purchase. Any help or input would be appreciated.

I encourage you to build a modern kit instead, there are many great one's.

In about the form factor you are thinking of, I really like the components in this PSB kit:

You won't find exact replacement parts to build a pair of these.  The pair that Erik recommended is excellent although there are a ton of lower cost alternatives.  If you are interested, let me know and I'll be happy to provide you some designs.

They are only expensive relative to other kits. The parts are very similar to those used in a $20k Sony speaker system. Compared to that, this kit is a bargain! :)
