Hi to all!
I'm new to the forum and also i'm new to diy speakers
My project starts from Paul Carmody's ZX Spectrum/Amiga, a floorspeaker 102cm height, 21.7 wide and 29.3 depth with HiVi M6N woofer and Monacor DT-300+waveguide WG-300. I choose this tweeter with his waveguide because i found it at a really good price and it seemed to me good for crossing with M6N at 2kHz.
Vent is 5cm diameter (length will be probably between 8.9-3.5" as in Paul's project for a F3 of 42Hz).
This is the cabinet sketch:
I added a close part at the bottom to have the speakers a little bit higher: here i will put the crossover.
I need some help for the crossover because i found the specs of the DT-300 tweeter but i can't find the specs of DT-300+ the waveguide WG-300. I found only some data about SPL increment:
Hz/ dB Increment
600/ +4,5
1.000/ +5
1.500/ +8
2.000/ +8
3.000/ +7
4.000/ +5
8.000/ +2
10.000/ +0
The waveguide will improve response of the tweeter at lower frequencies, probably facilitating the crossover with the woofer but i don't want the tweeter to be too loud...
This is the graph of the DT-300 without WG-300:
I made a test with X Over pro starting from the DT-300 graph and adding the db values written above. Crossing at 2000 hz with 3rd order Butterworth
Anyone could please help me designing the correct crossover?
Many thanks!
