Default Totem Rainmaker tweeter replacement

Hello,
I picked up a pair of Rainmakers. Nice speakers, definitely a different sound from Vandersteen 2c's.
I noticed one of the tweeters had been pushed in. I took it apart and pushed it back out. Sounds fine, but I inquired about replacements and the dealers are quoting me aprox $180 for one tweeter. Quite a bit more than I'd like to spend
Its a Seas H1284-06 25TA/G-TO not available any more.
An externally hosted image should be here but it no longer works. Please upload images instead of linking to them to prevent this.

Madison suggested the 27TBFC/G (H1212) $52 each, If I by two I can have enough left over for a nice dinner. . How would this change the sound?

Thanks
mdr

Link to old tweeter data:
Seas 25TA/G (6Ohm)

the 27TBFC/G is slightly more efficient, so level may need tweaking, otherwise looks like a good replacement

It's a non-ferrofluid SEAS tweeter, usually designed for replaceable voicecoil so I think you may have adequately fixed it.

SEAS have been doing 26mm tweeters on 104mm cutouts for years, and I wouldn't be surprised if newer voicecoils fit older models.

IF I was replacing here, I think I'd stay true to the non-ferofluid 92dB 27TBC/G spirit:
H1147-06 27TBC/G

Some people prefer non-ferrofluid. You may want to adjust level slightly. Generally each ohm drops you a dB, so perhaps an extra ohm at the input required for replacing a 91dB unit. I like a Zobel (7.5R + 0.68uF) with metal domes to round off their sharp nature.

I'm also sorry to revive this old thread, but it suits my question perfectly:
I need to replace my Rainmaker tweeter. Would the matching SEAS 25TAF/G work? There are some on eBay.

I'm asking because I read that Totem modifies the tweeter somehow, so I'm afraid a direct replacement could not work... According to some websites, Totem adds a custom rear ressonance chamber. I dont know if its glued to the tweeter or not.

Any help is greatly appreciated.

Thanks

I am seriously considering starting up my own speaker factory. If Totem can start up some line of products called Rainmaker, maybe I should go for Widow Maker!

TBH, these people are having a laugh in suggesting their tweeters are better than anybody elses! I visited Moss, Norway years back. Nice enough place.

Tweeters are tweeters. If you are replacing something that got blown up at a Party, and to blow up a tweeter with a 5" midbass takes some effort, here's how it works:

Now really, just get a new SEAS 27TBC/G: H1147-06 27TBC/G

Adding to this (sorry, I didn't find the edit button), I found some images of the tweeter in question, with and without the said chamber added by Totem:

I'd like to know if this chamber is removable somehow, and swappable to a new tweeter.

The totem-modified 25TAF/G appears to have a hole that the stock SEAS spare does not:

The original looks most like a modified H0831-06 27TFF. The added chamber lowers the Fs slightly. The 27TBC/G has a chamber.

I can only tell you what your options are here. Me, I'd get a new whole tweeter.

You might go to madisound and try a replacement voicecoil:
SEAS H9909 Voice Coil for H398, H400, H417

Or get a whole new unit which looks similar:
H1147-06 27TBC/G

Nothing stopping you playing with ferrofluid:
Blue Aran - The UK's no.1 Loudspeaker Component Stockist > Sonitus Audio > High Frequency Drivers > Ferrofluid

Ferrofluid is optional. It changes the impedance and frequency response slightly:
Vifa C17WH-

Level adjustments are easy enough for the cost of a ceramic resistor. I have already suggested how to do that:

Each ohm is about 1dB level change.
