Apogee Duetta II Signature Crossover Caps Recommendations

Hi Richard, from scratch you should roughly expect to pay $2,500 for all of the needed ribbons, acoustic foam, front and back socks, and wiring kit (for mid/high ribbons which includes (much improved from original) tension clamps) and Bill’s labor is a flat fee of $2,500. They also have an auto shop they use for painting that typically costs $1,200 (I’m doing a semigloss satin black). The only thing left would be to swap all of the Sprague capacitors which is typically about $1,400 when using caps they recommend (the speakers use a lot of them) and potting the resistors with epoxy. If you need shipping crates built they run $600+ from someone like Navis. Bill Thalmann is super-busy and the best way to reach him is via email at bill@musictechnologydotcom (typed out dot due to Audiogon’s filter). Cheers! 

Parker65310...thank you very much for the detailed information. At least now I have a good idea what to expect should I choose a rebuild.

You’re welcome. Feel free to message me privately if preferred. Same goes to anyone else looking for specific info that may not be appropriate for a public forum. No need to track it all down yourself when I’ve already done countless hours of my own research and amassed various top quality sources and articles.

@parker65310: thanks for the great info. Does the parts cost of $2500 include the bass panels?

How do you like the refreshed Duetta Signatures? I have owned the Duetta Sigs for over 30 years. Fortunately they don't have the dreaded bass buzz, but I may upgrade them.

Make sure you take into account the equivalent series resistance (ESR) of the original caps. With any speaker but with low impedance speakers especially, changing this without appropriately compensation could be a very big deal.
