Pete Schumacher ® replied to a thread 3-way build driver suggestions needed in Tech Talk Forum

Wolf replied to a thread Anybody noticed a trend in cap construction lately? in Tech Talk Forum

Correct. Those are pretty much the DTAC or "Doorknob" capacitors. FWIW, I looked up Wima caps at one point, and they also make a doorknob-style...

Nope- the box response will be different with the DCR change. It affects Qes and therefore Qts. It will affect tuning of the box, and maybe even box...

Your impedance is sitting about 2.5 ohms at 90 Hz. For 4 ohm nominal, my own best fit dips to no lower than 3.3 ohms. I think yours will tax some...
