B&W 805 models...

"Is the 805S better than or equal to the 805 signature?"

Depends on who you ask. I've owned both. Both did things that I liked. My preference, I liked the sig 805 better. The 805S is still a fantastic speaker. Alot of people disagree with me. I think partly because most want to like the new stuff out there.

I forgot to add the B&W Silver Signature!

The Natuilus 805 is not necessairyl better than the Silver Signature. Depends who you ask.

Therefor the order from Oldest to Newest:

Matrix 1
Matrix 805
B&W Silver Signature SS25
Nautilus 805
Signature 805
805S

S7horton,
i apologized,your right.

According the British HI FI Choice (May 2005 issue), the 805S significantly outperform the Sig 805, sonically speaking.

Marketing or... - I don't know.

BTW - many roumors about (possibly?) newcoming 805D - presumably improved 805S in several areas, with major gain in Diamond tweeter...

I have these speakers pair of 805N, and a pair of 805S I bought the new. Started out with 805N as a stereo set up then upgraded room 5.1 So bought the 805S and HTM4 for center. These are outstanding speakers. But lack low bass. I would not recommend these speakers without using a sub. Let me add this too. I would add a self powered sub to all speakers. This really takes the low end of the main amps and speakers.
