Hello all,

this is on sale here for about $25,-

It's being advertised as made in Taiwan and has modelnumber 454.

Does anyone of you know what it is and maybe even know some specs?

Thanks in advance,
Johan

These Ribbons are the same as used in my BNS evolutions (also made in holland) which is a great speaker.

Where were they on sale ? I would like to have a spare one.

I ordered two of these units @ brigatti, and they arrived pretty fast. I took one of them apart to see how they were build. It looks to me they are build somewhere in taiwan or china as a low cost, medium quality, ribbon tweeter. And the fact that they are sold under various brandnames agrees with my findings.
I don't say it looks bad, but it is no high-end build quality either.
Maybe that also explains why the units in my BNS speakers say "specially selected" they probably select the good one's out of a bunch of units from variable quality, because that's cheaper then buying a brand/model that's always good quality.

I would however advice you not to take these units apart since the chances are quite big your unit will perform less after taking it apart and putting it back together. The ribbon itself is glued to the plastic and when you separate them there's a big change you will deform the ribbon.

greets,

Willem.
