Magnepan 1.6 active 24db slop better than stock?

With 'ya on the thumps. A nasty thing to do to a tweeter. How about a turn-on delay relay? That help?

As for the x-over. I'm going with the measured results from Stereophile. The 2 drivers have very equal output at about 600 hz +-20hz. They are individually several db below 'average' output, and so the sum is pretty flat thru the passband. (right term?)

Also, consulting the measured data, it makes me even more convinced that changing the inductor to an ultra low DCR value is a mistake, raising output below crossover. This is already shelved UP vs the above-crossover frequencies.
Stock inductor is 16ga, iron core, of 0.40ohms DCR. You can easily buy an inductor in various configurations, down to <0.20 ohms DCR. No thought is apparently given to coil shape optimization.
My simulation yields a 14ga coil with as many turns as layers.....theoretically near-perfect. And, it is aircore with a DCR of about 0.38ohms, and will be inaudibly louder than stock. But, with near-zero chance of saturation at the very highest levels. The OTHER advantage of my coil, is that it uses Standard values of PVC pipe for the core.

Magfan... I redid my crossovers using an aircore inductor with lower DCR (don't remember the value). However, if it slightly boosts the woofer output this means that there is less need for a tweeter pading resistor. Overall results are good. The speaker measures flat, but by the time that room equalization is done flat response is not needed.

Darn it Eld, you are right! Less need for padding resistor, if you were so inclined in the first place!

In my case, I kept away from the urge to install one by the simple method of flipping my panels around and listening to the pole piece side. This is the 'old' orientation, changed in the 90's for some reason.
I find the 'old' orientation to be less beamy, less strident and having a wider sweet spot. This is with tweeters 'in'...formerly they were 'out'.

Please, call me Mag. That magfan things sounds so....formal!

Now the 10$ question.....When you redid your crossovers, what CAPS did you settle on? For reasons of cost / benefit, I'm thinking Clarity SA. with maybe a more 'premium' by pass of 0.1or less.

Mag... I used Hovland. For best bang for the buck, and ease of work, I would recommend leave the Solens alone and put the $$ into a good inductor.
