Worklog: D-I-Y 2.1 "ROOF ROCKER" Computer Speaker System
 

I`ved made a worklog on my current Computer Sound System :)

Getting ready for box tuning @ 40 HZ fine tuning it to it`s maximum intensity...

This is my project plan :peace:

My house roof started to rattle during my actual sound testing using my PC at mid volume :rockout:

Merging it on my current 5.1 Speaker System, a total of 7.2 :wtf:

Comments and Suggestions are very much welcomed :) good or bad :toast:

Your craftsmanship is pro.

hello, yeah thats very nice work, nice colour too :)

That is sick LOVE it :-) Thanks for posting

you mean craftmanship level : asian
XD

i like what i see. too bad we cant hear it :(

I was thinking of building a 12 inch version on this project, it`s still in the drawing board though :ohwell:

any comments?

Just a question... Have you tested the speakers in different size boxing to receive the best possible sound from them or did you just build to your needs?

However, great work man! :toast:

Thanks bro :) actually im just doubling the speaker manufacturer`s minimum sound box measurements which is 12 cu.inch for a 12 inch sub woofer because i cant properly tune

or optimise thier preset (12in.X 12in.) measurements @ 40HZ signal input, it seem so weak on my Db meter and in my ear hehe no matter how hard I tried it just does`nt satisfy my ears :ohwell:, I want my box to be as loud as

possible at low frequency sound, the box design is a ported type on the outside but i made a special divisions inside (for fine tuning purposes) to optimise it,

tuning it as loud as possible on a 40HZ signal at 20W of power, basically it`s the harmonic frequency response generated by the box that`s making it sound

louder, I did also tried tripling it`s dimensions, it`s a walk in the park to fine tune on 40HZ @ 20W but it`s so bulky already hehe, the doubled version i

made has almost the same intensity on a triple version and it`s more compact and small but a pain in the ass to fine tune @ 40HZ though...I`ved cut 7 times :banghead: on

the division lengths (Front and back) just to get the optimum low frequency harmonic response on it...:laugh: i`ved spent almost two days on just tuning it :twitch:
