what do you guys think is the better subwoofer. i would use it mostly for music which i listen to almost everyday and movies that i watch once a week. im from the philippines and the brands most recommended arent available here like svs and hsu. or i have to pay astronomical delivery fees. of the subs i auditioned here, i cant seem to decide on the following:

1. klipsh rw-10 (ported)
-Bass-reflex powered design, 10" front-firing aluminum cone woofer, 280w BASH digital hybrid amplifier, 25Hz-120Hz ±3dB, 39 lb.
-- MSRP: $ 499.00 i could this for 24,000 pesos here

2. velodyne cht-10 (ported)
- i could get this for 24,000 pesos

3. usher sw-103 (ported)
- * Sensitivity:88dB 1watt/1m
* Nominal impedance:8ohms
* Frequency response(-3dB):28Hz~180kHz
* Power handling:100watts
* Dimensions(wxdxh):33cmx49cmx48cm
-i could get this for 19,000 pesos

4. wharfedale sw250 (sealed)
* Amplifier Power: 250W
* Input Sensitivity: 325mv/150W
* Frequency Response: 30Hz-110Hz
* Maximum SPL Crossover: 35Hz-85Hz
-MSRP: $ 700.00 i could get this for 20,000 pesos here. wharfedale products cost cheaper here in the philippines.

5. dali concept sub (sealed)

or would it be better to get wharfedale sw-150(ported) cause it only costs 9000 pesos here. this sub won product of the year in whathifi. would the performance that i would get be negligible if i opt for the higher models listed above? or would i be dissappointed in the long run if i get the wharfe sw-150.

hoping that you guys could help me. thanks a lot.
