I bought the same set 3 months ago, w/o a RABOS kit. Cost: $100 due to overall condition. I bought it mainly for the sub, which is whoopass. I already have a RABOS kit from my Infinity IL60s.
In the past 6-9 months, I've seen a couple of sets offered ($150 - 200). Both were in excellent condition, but took MONTHS to sell. I know the quality and sound was there. I suspect the color (silver/gray) was a hindrance...doesn't blend well. PLUS, an odd shaped center. I recommend KEEPING...this set has Infinity's CMMD drivers PLUS a RABOS kit. Rare, rare find in my opinion.
