Totem Sttaf DiY

[prospero21]

Hello all,

my father owns a couple of Totem Sttaf's and since I really love their sound, but I dont have the funds to buy the real thing, I'd like to have a go at making them myself.

I already found a topic here on this forum about their Mite speakers, where a kind person already gave some info on the drivers which they use in their Sttaf's.

Tweeter: Tonsil GDWK 11/100
Mid/bass: Tonsil GDN 13/40/2

I contacted the manufacturer and these drivers are freely available straight from the factory, at REALLY good prices !

However, I cant seem to find information on the required filter-parts and chassis dimensions anywhere on the internet. I did find a polish site, but since I dont speak that language and the translation from google leaves much to desire, Im afraid that wont be of much help either.

Is there anyone who has information on this ? I'd really appreciate it !

Thanx in advance

Just out of curiosity, how much are the "Tonsil" drivers?
I know it's not a perfect "clone" of the model you're after, but you might be interested in a design I'm currently working on that is meant to look just like a Totem column speaker. The drivers will be the SS 8545K + Vifa D25AG-35 (I will probably also model a few other tweeters as well). (I have one other (much less expensive) midwoofer that I will probably also model for the design)
Info here, scroll down to near the end of the page to see sketches:

I don't speak Polish either, but I'm just tossing it out there, if it interests you.

Hi undefinition,

thanks for your input !

The Tonsil drivers are actually much cheaper than you would expect. About 20 EUR for the tweeter and 25 EUR for the mid-bass

Your sketches look great, indeed very Totem-like. Im taking your driver suggestions into consideration, provided they are freely available here in the Netherlands.

I don't see how those drivers wouldn't be available. They've both been around since the 1990's, and have been used an awful lot by the DIY and commercial market.

...anyway, you got me curious about those Totem drivers. Only reason being, that while looking through their designs, I couldn't help but notice that their OTHER designs have drivers I'm pretty sure I recognize: "Hawk" looks like a SS 8530K Revelator + some sort of LPG tweeter, and "Forest" looks like the HiVi D6.8 midbass + Seas 27 TBFC/G (maybe?)

Have a look @ http://www.protonsil.pl

They list their drivers on their site.

I just browsed through the website of one of the largest audio supplier here in the Netherlands and these drivers are indeed available. They are however a bit outside my pricerange, as 1 Scanspeak 8545K will set me back around 170 to 180 EUR.

I did however see they can supply HiVi drivers at low cost (around 30 to 40 EUR per driver) so I might see if I can design my boxes around these drivers as a side-project.

But I'd still like to clone those Sttaf's, so if anyone has any more suggestions ?

Should be easy to clone, Specs are here:
http://www.totemacoustic.com/product...pecifications/

from Tonsil web site xover is at 2.5 kHz, woofer impedance at 2.5kHz is 5 ohms. tweeter impedance is 7 ohms.

A should be easy to do a 2nd order Xover from that. If you don't know how, have a look at Jay's page on designing xovers using manufacturers specs without measuring:

and ask us for help on the way.
But before you start, check you have the right driver codes, Totem says the Sttaf is 8 ohms, but the drive unit you gave is 4 ohms...

Thank you very much ! Since I'm a bit new to all of this, these are the nudges I need to further along my first "real" DIY speaker-building

You are right about the 4/8 ohms, there are actually 2 13/40/2's available from Tonsil. I spoke with a sales representative and they said to list the code, plus the desired ohms. At first I was "confused" by this aswell, but they reassured me I had the correct driver-code.

Thank you for your information !

[edit]

I think there is a small error in the url you provided ? I assume its this page you we're referring to ?

Ah, very nice. Only problem is that I don't really speak that language. Judging from your location, I think you might ?

If you are willing, could u distill the information on the filter and design from that thread ? I'd be very grateful ! I've also ran that thread through the google translator, but I still couldnt make heads or tails of it...
