Choosing Crossover Components

[Roland68]

Hello,

I purchased plans for the Heissmann Acoustics DXT MON-182 speakers. The plan designates the values of the crossover parts but not a brand or model. So I have been looking over parts and have questions.

Inductors

Some inductors are bare wire and others are coated. Is one better than the other? Is it ok to mix brands to get the right values? Or would it be better to get the same brand but fudge a little with the values.

Capacitors

Jantzen and Mundorf capacitors seem to be the most available to me. For Jantzen, is there a major difference between the Cross Caps and Standard Z-caps? I can't find one of the capacitors in the right value so I am choosing the Cross Caps one for that capacitor. It has been difficult to choose a model for the Mundorf capacitors. I want to get decent parts but I don't want to get parts that are disproportionately more expensive than the rest of the speaker. The drivers are less than $600 USD.

Also, would it be better to replace any electrolytic capacitors with a MKP of the same value? Or is that not a good idea?

Resistors

Would using wire wound resistors be a better choice than metal oxide resistors? Is ok to mix brands? Some of the values are hard to find.

Bonus question: Anyone have any tips on how to cut the angled chamfers on the baffle?

Any insight you might have would be appreciated.

Heissmann Acoustics usually lists the components in detail, including the respective manufacturer. If that information is missing, just ask. You can also check the parts lists in the kits they offer, as they are very comprehensive. Especially with the coils, you should only use something else if you are very familiar with them.

For the XT MON-182, you can also get completely milled front panels. With such an expensive speaker, this could be a worthwhile investment. Complete cabinet kits are also available.
