Hello
I hope someone out there is willing to provide me with some design help. I plan on building three way speakers for my local church charity auction coming up in mid April, I would like to use NOS drivers that I have accumulated over the years. I can handle wood working OK, I really need help with : 1. driver selection, 2. crossover and box design.
I already have a pair of Scan Speak 13M/8640 and two pairs of Axon 10k01 woofers. It would be great if I could use the Axon drivers- I know they make a very odd pair with the SS...
I am open to any tweeter option as long as the cost is reasonable (around $100 -$150 per pair).
I hope someone on the forum would be kind enough to donate their time and expertise?
Let me know
Jean

Post more information
Scan Speak 13M/8640
Axon 10k01 Woofer
Your question seems quite honest to not deserve an answer. Is there any more information (the necessary T/S param. specs and curves) on the woofer?
A possibility is this
Beston RT002A Ribbon Tweeter
BESTON RT002A
Dr. Mark Says - Dayton RS 150S-8 and Beston RT002A crossover and box alignment

Axon 10k01 Woofer

Nothing that a good googling on the net can't solve. I think we have a starting point for the Axon woofers: http://www.zalytron.com/pictures/Axon 10K-01.PDF
Good job pmolina.
It's pointing to a BR box from 35L/39Hz to 70L/43Hz (WinISD).
Thank you everyone. The Seas definitely would work for the price range, (I looked it up at Madisound). I also looked at 27TBCD/GB-DXT (H1499), also in the same price range- they have been getting great reviews as well!. Can someone provide input / recommendation on the crossover? Madisound states they would only design XO for drivers they sell. I really appreciate the help! Please remember this is going to benefit my local church!
Thank you again!

Thank you again!

Well, I am a little bit dusty on Xover design. The first thing is to generate a FRD file for the Axon driver. We don't have an impedance graph of this driver so we will have to simplify the calculations. I am attaching the resulting FRD file.
Over the weekend I'll try to find the FRD and ZMA files of the midrange driver and either tweeters we mentioned.

Thank you Pmolina!
I found one file at:
Seas 27TDFC - H1189.frd
Driver FRD & ZMA files
I am still looking for the others

After reading posts twice:
Tweeter Seas 27TBCD/GB-DXT - H1499: It didn't look right, who recommended it? From what I see that driver is going to be a difficult implementation, give me a good lead...
Tweeter Seas 27TDFC - H1189: this driver from last post that pmolina recommended (post #5) looks better, Jean.

I am attaching the files I used and generated to input on Jeff Bagby's Passive Crossover Designer. Unfortunately I got a Visual Basic error and cannot visualize the resulting circuit diagram, although I can see the resulting graphs and values. But I think this is only happening to me.
If anyone could open the files on Passive Crossover Designer and take a second thought, it would help. I think we are almost there...

I can't use (or import/copy properly) the files, is it possible
to have them like in the "Axon 10k01 Woofer" posted formated file from post #9?

PA 3-WAY XOVER FOR Axon 10k01-04 Woofer, SS13M/8640, SEAS 27TDFC: 52L/38Hz, 89dB, WMT
The others, that I can't read properly are from FRD, they are horizontal formated.
Any way I come up with a xover that can be looked at.
(Note: It's a simulation with no real driver data files, just to model a PA working xover).
It is interesting that when I model the xover I did a test for an WMT and WTM, being that the first models better, but I would love to build the second one (maybe better dispersion, I don't know, since one woofer and mid on the opposite sides), and they are very phase coherent, the 3 drivers from 500Hz to 5000Hz. Specs are 89dB +/-1dB (48 - 20KHz) w/-10dB@32Hz.
Woofer - BR 52L (internal)/38Hz
Mid - BR 5L (internal)/95Hz
Approximated size of the box external: H57cmxW32cmxD42cm
Shelf thickness (main box) in cm: 1.6
Volume total in Litres: 60.1 (counting w/driver vol. and ~6/7L box for mid)
Drivers:
Axon 10k01-04 Woofer
SS 13M/8640-00 4in Midrange
SEAS Prestige 27TDFC (H1189)
Yes, I know, that's vertical formated, it's good for me.
The others, that I can't read properly are from FRD, they are horizontal formated.

Xover: 2.order, 3-Way 250/2KHz.
Feel free to change at will and have a happy event. Enjoy.
I have four of these midrange units which were given to me to play around with. I intend to use in a design 2 per side parallel.
Did you complete this system and would welcome comments on this unit's sound quality
Thanks
Simon
