I spend money on parts, particularly for the tweeter. It can be quite expensive. There are various options. Right now I have a pile of copper film / foil caps from REL-CAP, i.e., "Wilson Audio Caps". I didn't buy them because of "Wilson", I bought them because it's copper foil, custom made in the values I need, and the pricing was very good - as far as "copper foil" goes. Although... they are copper foil and poly, not copper foil and paper. We will see how they work out.
The 10uF Copper Film / Poly caps from REL weigh 1 Pound EACH.
COPPER.
I like soft dome tweeters and paper cone woofers... and also planar magnetic tweeters - I'm listening to 12 of them right now in a pair of Line Arrays. With the resolution from the planar magnetic tweeters I have and the likely resolution from that tweeter in the Gobel Divin Monarque, I suspect it may very well like some copper foil too. At a minimum, I've found bypassing the tweeter caps in any network with a .1uF Duelund CAST-PIO cap is helpful. "Organic Detail". That's something anyone can do, if they can get access to the network for their speaker. It's an easy thing to try. A picture of the .1uF caps I use for bypass are below.
I am sure Gobel has spent PLENTY of money on parts, and it would be interesting to know what was chosen for the inside, especially given the obvious attention to detail by the designer.
I have pair of Wilson Audio Duette with a custom network... No idea what was inside the OEM network, as it's potted.
Wilson likes to try and keep it all a mystery... but they will also sell the same caps they use in their speakers. I don't have the Duette because they are "Wilson Audio"... I'm not a "Wilson Audio Guy". I have them because they are a well built, kick ass 8" 2-way with Scan-Speak paper cone woofer and Scan-Speak soft dome tweeter. They just needed a new network to be "right", and I use copper foil on those too.
