Loved both interviews re speakers. Learned a lot. Have owned more speakers than I want to admit to. Question what does he think about the Martin logan electrostatic speakers bought a set this year love them however want to see what his thoughts are? By the way great podcast have heard every one you guys have done😊
Hi Bob,
I forwarded your comments to David and this was his reply:
I’m not a fan of electrostats, though they do do some things well.
A very good friend collected these, over many years, so I got a chance to hear maybe 20 or 30 different ones.
Here are my objections:
1. Yes, it’s a single ‘drive unit’ (for most of the range. Many of these use ‘integrated’ woofers now). But it’s not like a fullrange speaker. The sound comes from an enormous panel, not a single point in space. So imaging is far from ideal and they never ‘disappear.’ This also affects ‘soundstage’ (front to rear) as well.
2. Manufacturers of planars and electrostats claim that the membranes are so light they’re ‘quicker’ than normal speakers. However, I spoke with a designer at one of these companies, years ago, and he laughed. He said ‘yes, the membranes are light, but the magnetic field moving them is VERY weak’. So, the end result is that a speaker, such as ours—with huge magnets—actually has more control over the cone.
3. They place extreme loads on amplifiers (mostly very low and constantly varying impedances) and often cause them to blow fuses and shut down. A very hard load to drive. And most of these panels are also very inefficient and require very powerful amplifiers—capable of handling very low impedances.......as low as 2 ohms.
4. They’re expensive, fragile, and take up too much space in the room.
This guy's beliefs are seriously outdated. Acousticians are generations beyond the crap this guy's spouting.
