Clarity MR caps for external crossover?

Better to keep old network intact build new one compare the 2. How can you tell If its a real improvement unless you have a base to compare too. Best is to have 2 of the same model keep one stock make upgrades to the other compare measure changes. If not then its a true shot in the dark. For what I see some spending on over costly crossover parts they could afford this with ease.

The MR's have perfect synergy with Tannoy drivers.

For the values that CC does not make, split the value in half. Using unequal values, especially in series with the tweeter, will have a negative effect on spacial information.

As for the 200uf, I would consider ESA's though.

And I agree with Magfan in using an air core inductor for the LF circuit. Be sure to match the DCR withing 10, preferably 5% or you'll be sure to create undesired effects.

Does Tannoy make there own drivers? Do they use SEAS or Dynaudio?

I like the idea of comparing 2 complete crossovers......You can than basically A/B them and see which is superior.
Going at this piecemeal may drive even a stable person crazy.

OH! one other thing. Many online inductor calculators exist. Some allow for more changes in dimensions than others. All can use any wire gauge.

My inductors for my Magnepan 1.6s is an aircore near-duplicate of the iron core stock. New is 14 ga. and 0.38ohms while the original is 16ga and .040ohms.
Within the 5% suggestion of Face.

Also, my inductor is 13 layers of 13 turns, so it is the theoretical 'perfect' shape for an inductor.

And to ice it, I managed to use as a core, some PVC so the size is both available and cheap.

I started an Excel spreadsheet and just started entering data spit out by the calculator I chose. Once I discerned a pattern, I zero'd in on what I wanted. THAN I checked my work on a couple other calculators. All agreed.

Thanks to all for your comments. After months of study, I have selected all parts for my crossover project. Decided to go with Clarity MR because of (IMHO) the price/value ratio, and because it's what Tannoy chose for its new flagship Kingdom Royal. Will report my results some months down the road...
