Hi all,
I am beginning to build a thrusted project, Zaph ZRT two way, and *obviously* I wish to make all by myself, without madisound cabs.
Now I have some doubts about cabinet sizing and crossover components. I will be a little schematic here, hope this don-t hurt.
1. Cabinet. I would go traslam, a la Magico Mini, tower version. This is leading me to madness, couse I wish let the baffle dimensions identical as the original BUT this maybe excludes the possibility of a largely rounded baffle. I would make substantially an 1 inch radius roundover but how can I obtain the effective, corrispondent dimension of the original project baffle width (sharp edges)?
Should I consider an average point? only the external distance between the side walls?
Please give me any imput about this.
2. Crossover coil(s)
I am choosing the right caps and coils. The original Zaph's scheme claims for a 2,7 mh coil for the woofer, with a rdc of 0.168 ohm. Essentially he go for the cheap way, and I could agree but living in Italy I must use other stuff, not exactly with same specs.
I could go essentially for this 4 solutions>
a. munforf flat foil inductance. Expensive and with an rdc of >0.30 ohm. Worth the extra cost or will simply ruin the damping of the woofer (double the rdc) without evident benefits?
b. Intertechnik generic ferrite coil. wery low rdc (.11). Maybe too much low? Could be a problem?
c. Intertechnik tritec litz hq ferrite coil. Fast right rdc (.15), a little expensive but affordable.
d. Mundorf zero ohm coil. Hilariously low rdc, expensive as a mid level tweeter but maybe a good way to obtain fast, damped bass. Maybe definetively overkill anyway.
What would you use? Eventually a 5th option is welcome.
3. Crossover/ general.
I think going with obbligato caps (tweeter series) and lesser poliprop from jantzen (crosscap) or similar. I have read a lot of different opinion about parallel caps... some people claims for the absolute importance of HIGH quality caps in this places too....other prefer to alternate very good ones in series with cra**y ones in parallel.
What do you think about?
I would hear any feedback, considerations, advices from diyers and people more expert than me.
thanks!
