[Sub for my room?]

I have a car battery which runs the amp very well,I'm okay with this matter

But I'm worried with the sub box..I know nothing on T-line boxes Guess i'll check a related thread I found and then see what I can do

[Sub for my room?]

I want it to play music,almost daily use

Uhmm...Any sites that can help with the design of the box?I know how to make L-ported boxes but I've never before experimented with transmission line ones

Okay,thanks for your answers so far

[Sub for my room?]

Well hello,this is my first post

I have seen many videos about the Sundown SA-8 subwoofer which i found popular in here

I came to ask...Is it worth buying for using it in my room?

I want to have clean and LOOOOW bass

Some other things now..

I already have a cheap Mac audio sub which is basically kind crap (Trying to sell it-no buyers for it )

I've also got 2 oval speakers for the vocals and a cheap car batt.The amp i use is this one: http://www.mac-audio...c94019fb2b11fdd

(I always use the Logitech Z 2300 btw,main pc speakers )

I don't want to buy something that will not make any difference from what i already have..Can this sub handle the low's well?It's gonna get only a little power (around 160rms).Is it worth buying?

I've also considered something else--->SA-8 or the speaker set of Edifier S730 ?????????

Thanks for your time
