for home theater I would think ported due to efficiency and lower frequency extension and speed. 2 Channel...hmm..both would work...but very music dependent. plus, your pushing 150W...not too much, the rest of the system would have to "match" per se to what the SW could handle. Visa Versa. ULTIMATELY...personally, I would go for ported.

Do you have the 10" driver in your possession or selected? If so do you know its parameters?
If not, it is a safer bet just to put it in a 30~40L sealed box.

i already have a pair of 10"/150w SW driver.. still have to decide though as to what type of enclosure would give the better bass effect

The type and design of the "best" enclosure is very dependent upon the physical characteristics of the driver. Some 10" drivers are better suited for sealed enclosures, other are best in ported enclosures. These parameters also determine things like enclosure volume, port size, etc. Do a search on "Thiele Small parameters".

If you have the T/S parameters, or details on the driver model/manufacturer then post it here and some folks can better help you with your design.

Good luck,

Bill Rankin

Sealed subs are sometimes considered more musical. They roll off more gently than ported subs, which can make for a more natural match with the room's "transfer function" or gain at low frequencies. Lower order designs should have better transient response. They're more tolerant of errors in the woofer's Thiele-Small parameters, and published specs can often be very wrong; it's always preferable to measure the parameters rather than trust numbers that could have typos or were based on a pre-production prototype.

Yup. Sealed boxes have better transient response. But ported boxes can have more output (both sensitivity and maximum output) in the low bass IF IF IF:
- You have a big enough enclosure AND a big enough port (which is often a problem)
- The driver parameters match the enclosure.

So I'll echo the "just put it in a sealed box unless you can measure the parameters" or get a very trusted spec sheet. What is the brand/model of the woofers?
