[asbn369]

hi,can anyone give rough dimensions(rough only)for making speaker enclosure(2 way- 4 inch woofer and tweeter).i dont want all those advanced calculations,freq etc.just rough dimensions.plez help!!!

Must be about 5.67 litres ...

Big enough

Seriously, we need more info (what drivers are being used?) for any useful answers. Otherwise, it's impossible to say.

Hi,

For a typical 4" woofer your looking at around 5L to 6L internal volume sealed
and stuffed. Anything more you need driver parameters, vented might be 7 to
10 litres but this is nowhere near as safe as a universal 5L sealed box.

Linearray is not being as trite as it may first appear.

If you find the bass is low in frequency but weak in volume, try adding some solid filling to your cabinet to use up the extra space (approx 1/2 litre at a time until it sounds good). Sure beats making new ones if they are not quite right and you are just winging it like this.

Hi,

No, filling a cabinet is always a bad idea except for unusual cases.
Generally for the case you describe it should be converted to vented.
Vented is quite forgiving as a long as you always tune relatively low.

You're probably right Sreten, I just have an aversion to vented cabinets for the most part. Perhaps a 4" woofer is an ideal candidate, I don't know.

I beg to differ unless by unusual you mean a cabinet that is too large to begin with

Hi,

A 4" woofer is certainly not the ideal candidate for vented, sealed is better.
Your right in that by "unusual" I implied a stupidly large volume for the driver.

As for vented tuning, its wonderful, but can be done very badly. With it you
can produce the absolutely awful maximally flat responses to the stuff I like,
pseudo 6dB/octave roll offs that sealed boxes cannot do except in massive
boxes, and do not forget a port quadruples a drivers capability at the port
frequency, engineering wise this capability is totally impossible to ignore.

I allways tune low, where the driver is running out out of capability
to produce low bass rather than the typical maximum SPL tunings.
Tuning low is also necessary to create the overdamped alignments.
