I am looking into a new sub and amp. I have a sealed box with 1.25 cuft. Also, I have a spot on my box 15"x12"x3.5" for the amp. My thoughts were of getting the 10W7 with a 500/1 amp. My friend was telling me to get the 12W7 or the 12W6v2 over the 10W7. Will the 10 be more accurate or will I notice? I also wanted to know if the Eclipse Ti was a better choice for the money. My main thing is SQ but of course I would like it as loud as I can get it too. I know it is most likly opinion but I am torn between spending $500 for the 12W7, $385 for the 10W7, $400 for the 12W6v2, $340 for the SW9122 or $300 for the SW9102. Also I would have to look at amps and which would be the best. Please let me know your opinions.
