1. What are your size limitations for a cabinet?
Ans : Approx. 6~7 cu. ft.
2. How many cabinets are you planning to use at one time?
Ans: Minimum 2
3. How much talent do you have in cabinetmaking? Building a horn
loaded or bandpass cabinet takes quite a bit more effort than a
vented design.
4. My friend is a professional PA cabinet maker. That's why i can do it as i want.
Finally, one comment about the thread so far, having maximum output at 80hz does not necessarily mean that you need a "long throw" design.
Also, you need to be aware that designing something like this can lead to the classic "one note" subwoofer, known too as the "boom box" effect. Other parameters and function can be degraded to a noticable point doing this.
Ans: Yes, I agree with ur views, but my frind likes this kind of bass. So he want me to design this for him.
