I had read some negative feed back on THAT DAMN Seas midrange driver like thin, metallic, clinical..........QuoteWhatever the weaknesses of the HT3 (or HT1), I'm pretty sure they're not due to the midrange cone material. I designed an alternative version of the HT3 using the W18 Nextel (coated paper) cone instead of the magnesium (the two drivers are otherwise identical in construction and price). I wanted to make sure the metal cone wasn't introducing spurious "detail" or other kinds of distortion, and if it was, I wanted to be able to offer Jim an alternative. I didn't have any vested interest in the outcome. Paper? Magnesium? Whatever. I was pleased with the outcome, but it was basically the same speaker. I couldn't pick up on any real differences in either the final measurements or the sound. It was an HT3.

We hope to do some carefully controlled blind listening to a variety of drivers with different cone materials this October at the Wash. D.C. DIY2008. It should be interesting.
Whats this DIY 2008? I live in DC, sounds interesting...
...sometimes when I look at that side I'm sad and miss enjoying those tunes....
My association with the W18 predates Salk--Dave Ellis asked me to whip up a design with the W18 and the 0W1 (the "1801"), and I could tell right away that the Seas was a winner. The HT1 is essentially the Ellis 1801 with a ribbon tweet, and the HT3 is an HT1 with a woofer. I have, however, been constantly perplexed by the frequent bad raps this driver gets--I'm convinced no one would hear any problems if they thought they were listening to a paper cone.
