Red dot on tweeter

[guy]

Hi,

looking for advice on tweeter polarity - Scanspeak D2008, is red dot (brown cable) positive?

Yes, terminal marked red will be tweeter's +VE, however it may be connected electrically out of phase to be acoustically in phase around the crossover point.

Cheers - I wanted to know as I was changing over the D2008's for a Hiquphon OW1 (which has + marker on terminal). Apparently, as you say, the tweeters are connected out of phase at the crossover but I just wanted to do a "like for like" connection.

Now all done and feeling rather pleased with the job :)

The OW1 is likely to be a couple of db less sensitive than the D2008. You may or may not notice this.

Yes, that did worry me but initial impressions are very good (using in a mk1 Rega Ela)

Most of the speakers I've tried would have benefitted from a 1-2db drop in the treble. The ones I've found most satisfying in the long run are those that wouldn't, Kef Reference Models 1-4 and my current Amphion Kryptons.

I though you meant something like this.

This is red felt inside my Monacor DT300 tweeter.

This required some surgery on the driver.

I think that would be well beyond my skills :eek:

No worries.

My post was genuinely driven by what first came to my mind...

But then I look at these dots every day (or they are looking at me).

Sort of I think - I understand that there was some sort of joint development early on but they went their separate ways, mine have the full length fluting on the baffle and a Royd bass driver (I think mine are unusual as they have had a wood veneer from new). Bass units still look and sound good, but if anyone has a couple hidden away I would be interested to have as an insurance policy.

I remember reading this review when it was first published (used to read lots of HiFi magazines back then, such a waste as I could have bought more albums:lol:)

This is an old one so I expect you know this: I would use a small battery connected to the inputs to see if the cone moves in or out .
