thank you for ur reply sifu zenn, quite clear about this.

but i got further question, mayb u can clarify this as well:
1. ur statement "u need a suitable amp that is stable at the lowered ohm value." usually amp ohm value is at 4ohm, u mean some amp's ohm not stable? going up n down?

2. SVC or DVC can hv double magnet as well?

3. if a sub woofer with double magnet required more power and if my amp not good enough (in rms), then also no use rite? for this case, i better buy single magnet woofer?

Go join TT listen and compare the sound of seal and port...hard to explain by words actually.

From my experience, If you were used to ported box, u'll find seal box is not loud as ported. However, the bass is more deep and low (thumping bass) unlike using ported box which is boomy. The seal box is much nicer and clean sound. The best thing about seal is you can feel the bass vibrating your heart.

I love seal box but if like to play loud then go for ported box. But it depends to invidual preference and type of music you listen to

i agree with u. what is TT listen?
