ADTG, the Silver S8 was fairly neutral, but with a very 'rough' response.
The entire Silver S series had a reputation for being bright, but measurements showed the tweeter level wasn't elevated.
I think the brightness came from other factors, things that can't be EQ'd out:
1. There's a directivity mismatch between the midwoofer and the tweeter.
2. The midwoofer has some metal-cone resonances that aren't sufficiently filtered out by the crossover. They can make the sound bright and piercing at times. People have often mistakenly blamed the tweeter for this.
3. The tweeter is dirt cheap and doesn't have any heat sink. Its sound gets 'hardened' quickly with increasing sound levels.
Check out Stereophile's measurements of the S2, for example. The overall on-axis response is anything but bright, but yet the speaker can sound bright.
