The F25 is looking very solid to me, and I think the price is great for what it is. I have always been pleased with the performance, build quality and customer service of my Rythmiks (2FV15HPs). Someone said it was 1800 originally, so 1399 intro now and 1499 later is a heck of a deal IMO for a commercial sub. Of course if you have the DIY skills you can do better, but that's not me at the moment. I know the DTS10 is a beast but unless you have a dedicated room you can basically build those things into its tough. I'm voting F25, but you are going to have a top performer either way. The caps are beastly as well.
I'm also not a fan of a company getting political like that, it's unprofessional. Nothing wrong with backing a candidate and making donations, but that was just weird going negative like that. Many folks are way too polarized right now when the two sides agree on 90% of the issues. Treating the other guys as the devil isn't working for either side IMO. I for one am sick of it.
