Can I use Seas P17RE. frekv,response 40-3000Hz, in a twoway
speaker, crossover 3000Hz whitout any LP filter as it only works up to 3000Hz.

No, look at its frequency response.
The 3k that Seas talk about is a recommended max range to take the driver too.
If the drivers natural roll off approximately was close to a typical acoustic roll off, ie 2nd order linkwitz then yes you could use it full range, adding a HP to a tweeter to match the woofs roll off. But in this case the SEAS doesnt have this.

Yes you probably could use it without c/o if the speakers
are not toed in.
But your forgetting baffle step correction : as its measured
in a 12L box you can see the 6dB rise between 100 and 700Hz.
You need an inductor for baffle step correction, juggle this
a bit and you can combine the crossover and some BSC.
Also checkout the P17REX driver and the Seas Embla Kit.

Yes I agree with sreten on this, you can use the woof no filter if you use it off axis. Having said that you will need quite a considerable amount of this to get like the 30 degree plot, well 30degrees if you like.
For instance if your speakers were facing straight ahead, positioned 2 meters appart with you sittings three meters away, the angle would be less the 20 degrees. So bare this in mind.

5th element said:
Just something to consider :
As the driver is measured in a presumably rectangular box is
the on axis response intrinsic or a result of diffraction effects ?
And possibly another point - you could also use a tilted back
baffle for time alignment which would increase the effective
off axis horizontal angle.
Don't get me wrong here - the above is theorectical and not a
good idea to use unless backed up with good measurements.

I use these speakers for my PC,and I thought if I could messaure
them from where I listen from,never done this before.I have a
Revolution 7.1 soundcard,but maybe the mic input of this card isn´t good enough to messaure with?And I have 3 different microphones Shure 588SA,Wellin DMW 908 And Primo C-2,they are for Singing and for instruments,how do I know if they are liniear to messaure with,can I check them somehow?Or could any one recomend any other mic for this not to expensive.As I have never done this before I would be glad if someone could explain this to me,maybe a schema for a good mic preamp,to use with the line input of my soundcard.
