cheapest on ebay is 335 shipped and 90 day warranty.
i went shopping for the same set today on 11th in downtown LA and the shops that still had some all said 300 flat.
i have the spx 17ref's now and upgrading to the PRO's this week
I have the spx 177r and also the pioneer ts-A1720c, but I still want to get the spx 17pro set ... Found someone with a used one but he only has the on axis module on the xover but not the rest . My app needs the other module since I'll be putting the tweets on the A pillar and mids on the lower door .
