Need Help: Design my Speaker

[jawedsoft]

Dear Friends,
Just seen another post by a FM in this section about principles of speaker design.

I am planning to make my own speaker as a part of a bigger project using Raspberry PI(Poor Man's Sonos).
Need some guidance regarding a couple of points... ( I did google before posting...).

Is it correct that I only need to provide the lowest frequency which I want to reproduce from the speaker box and based on that I get a cabinet volume in (e.g. in litres).

Then I can make up that volume in any way I want it...is it? I always thought that the shape too needs to be in a particular way....

For example I want to produce frequencies only in the range 150-14k.


So if I put in an appropriate driver, make the cabinet volume as suggested by the Speaker Designing formula on Internet then I will get the output sound..?

I know its complicated (lots of variables in the formula)than that...so I need help on this front...on any links which will help me make headway. or can someone please share their real experience...


My primary requirement ..at this stage, is a speaker cabinet which should be of around BookShelf Size and should be able to go down to 150 Hz or near abouts. ( I am hoping to have something around..8w x 10d x 18h)

regards,
Jawed

Hi Group !.
Season's Greetings.

I will make my query simpler now.

If I get a simple cabinet made of size 8 x 10 x 18 (inches) of 8 mm thick MDF, will I be able get low frequencies upto 150 hz? I don't want to use any other design components like ports or partitions.

regards,
Jawed Ahmed

Hi: I suggest you read this first. Then, please come back and re-frame your question/s.

So you are opting for a sealed design?
Sealed design is easier to make compared to calculation complexity of ported speaker enclosures.

And I dont think 150hz is that much low..
Also what speakers are you using for this project?
