For the vented box, go to WinISD , click on "online" calcultor and enter your driver parameters, this will tell you your vented box volume.

Go back to the original page and click on "vent calculator" and enter the necessary information, this will give you the vent length.

Here is a good primer on loudspeaker (inclduing crossover) design

Looks good
see the mid woof cone is breaking at 4,8kHz
so crossover at 3K more or less
put a trap at 5Khz
pad the tweet a little and use 2nd order HP filter.
start listening/measuring then tweek as needed.
Your mileage/km may vary.

My friend designed me a TL, he suggested it so I should be happy

I forgot this:In that DIY-speaker guide wood-screws werent used..wtf?Just glue

[69stingray]

Quality wood glue should work, especially on MDF material. For a sub or a speaker that will require some high pressure in the enclosure, I prefer to add a few screws, they keep the box together while the glue is drying (less clamps!!!!). Better safe then sorry. You will have countersink and fill the holes later before finishing.

Is it possible that amplifier "doesnt deliver" bass freqs?I connected sistem to the some "computer-few-wats" amplifier,but there isnt bass at all,just boomy s****(maybe box *can* be too little...)
