hmmmm, wrong address? Can't get it to work.

Hi, and thanks for the reply.

I don't have the midrange or tweeter yet, and there is one other problem I live in the Netherlands and shipping is very expensive and they won't ship outside the US.

here's the information on the woofer http://www.visaton.com/english/artikel/art_446_1_9.html Sorry I don't know how to post a link.

That doesn't work on my computer either.

closest thing on that site I found was

Hi.

hehe ok i'll type the whole list[]

You are right, it doesn't work for me either.

rated power: 75 watts

maximum power: 115 watts

nominal impedance: 8 ohm

frequency responce: fu 6000 Hz

(fu: lower cut off frequancy depending on cabinet)

mean sound pressure level: 88 dB 1W/1m

maximum cone displacement: 20 milimeter

fs: 30 Hz

magnetic induction: 1,1 tesla

magnetic flux: 600 u weber

hight of front pole plate: 5 milimeter

voice coil diameter: 3,5 cm

hight of winding: 1,2 cm

cutout diameter: 18,4 cm

net weight: 1,5 kilogram

D.C. resistance Rdc: 6 ohm

Qms: 3,59

Qes: 0,36

Qts: 0,33

Vas: 70 litres.

I hope thats the information you were asking for. otherwize ask me more[]

Those two woofers in parallel will get you 4 ohms. You don't wan't series hookup.

Typical/modern amps/receivers will handle that load.

If you are familiar with WinISD, then you know what cabinet size you need.

Now for the tweet and mid...are you going with horns? Do you have something in mind?

If so, I can give you an idea of what XO to make.

Hi, and thanks again for the reply.

Yes I already made the drawlings (with paint, please dont laugh[]).

And I also choose the tweeter and midrange, they are both titanium dome

speakers. The tweeter is 1" and the midrange is 2" they both have a

sensetivity of 92 dB, and with 2 woofers that will give me a

sensetivity of around 93dB all together. Since the woofers have a

sensitivity of 88 dB. And when you add a woofer it will add 6 dB.

Please tell me what information you want on them, and I'll give you all

the specs. Also could you tell me what XO means? I'm not familliar with

that word.

Thanks again.

Wolter,

X = cross

O = over

Crossover or network

Ofcourse, I should have known that[]

Thanks.

Hi.

JC, if you want the information on the squaker and the tweeter then

please tell me I can give you all the information on them you need.

I probably can get the squakers for half the price, but I'm not sure yet.

Wolter

[jwc]

yes... lets see the specs.

[Wolter]

This link works.

And now for the tweeter:

And the other one works too.

[jwc]

here is your network start

[Wolter]

Thank you very much Jc.

But I do have a few more questions if you don't mind:

Did you calculated the XO for 2 woofers or just one?

And when I am gonna built my new speakers, do I hook em up at 4 or 8 ohms to my amplifier?

Again many thanks Jc.

Wolter

I will be out of town a couple of days.

This is for your two 8 ohm woofers to be wired in parallel. That will make your low frequencies in the 4 ohm range. Just hook one woofer up to the network like the picture shows then hook the second one up to the first woofer in parallel.

I would start with hooking them up to you 4 ohm taps.
