Hi, I do know that this is a newb question (at least the search on the net shows that there are no 2-ways with that combination) but of friend of mine has these two and would like to make a 2-way speaker. Is it really imposible to mate them? If someone has a design with them or has an idea we will truly greatly appreciate it. Thanks in advance, please excuse my low level of logic, it's only based on lack of knowledge in the field. ops:
SS 8545 and Seas Millennium-possible?

Sure it is possible. I'd talk to Dan at http://www.knology.net/~wesnor/ or check out his projects that come close to your proposal.

Thanks for the suggestions, I hope that someone has already done something with them and will continue the search, we do not have any measuring equipment and that's a huge problem. One way to approach things is to use a proven box design for the woofer with a filter for it and try to adapt the tweeter. But if someone can help it will be really great... Thanks friends- Bottom

Here you go, this should get you close since I used measured files for the tweeter and simulations for the woofer.
Let me know how it sounds. Go here for cabinet suggestions to tune the woofer response and get the best bass response. http://www.troelsgravesen.dk/Amish_8545_9500.htm
Don't use his crossover obviously. My design is 4th order at 1.8K. The tweeter can handle it no problem.
The attached picture is how your box should look with placement of the tweeter. Feel free to make it a tower speaker, just keep the width around 8.5-9".

I played around a bit more to smooth the response. Here is the result. This is probably where I would start even though it uses a few more components. The impedance looks similar to the last picture I posted, so I didn't bother including it here. The 5mH inductor can be pretty much any DCR, so if it is 2ohms, then subtract that from the 15ohm resistor (change to 13ohms) so the total is 15ohms. The series 2.2mH should be 14 gauge aircore. Remember this is a simulation, but it should get you really close since I used SEAS measurements in the box pictured above, minimum phase, and baffle step compensation.

Thank you so much, I did not have time to log in the last days but seening this is like a dream come true, thanks a million again! I will be travelling around the world the next few weeks but when I come back the MDF dust will rival Krakatoa What a great forum, you guys are just 100% magicians!- Bottom
