IMHO, they would be a decent driver for sealed boxes for nearfield and car audio. Once you start talking 6 to 7 cubic foot boxes for ported, the space, cost of wood VS available SPL tends to overshadow the low price.
For the 300 watt plate amp/one sheet of plywood DIY sub market, the CS1214 ported really does not make sense. The JBL GT5-15 would work better ported. The 2" VC coupled with 14.5mm of Xmax reminds me of my GTO 1214 with the same specs. Did a quick and dirty model of the GT5-15 in a 6.5 cubic foot box and although not perfect, it does 20Hz without issue and costs $70.
The CS1214 is great for the price when used in multiples, but for a sub or two it would be better to look at something else. It is quite the stretch to call something with a smaller voice coil, less Xmax, less power handling, weaker motor, higher Fs, thinner/lighter frame, no DVC option, much larger box for ported and that garish 1000 WATTS on the dust cap a "replacement" for the 1260/1262.
A great option for sealed, not so much ported. Oh well, at least Harmon offered an option after they canned the 1260/1262. I'll be building a sub or two next summer, looking at the GT5-15 and Alpine SWS-15 and leaning towards the latter. The GTO 1214 will go nearfield so I'll watch to see what Harmon does in the next 10 months.
