Default Tivoli speaker

I bought a Tivoli Model One radio and am really suprised about the sound quality.
Any idea about what speaker is used?

Surprised pleasantly or otherwise?

I've wondered what was in there too.

I was suprised positively.
Looking for small speakers I found that there is a lot about the Tangband W3-871 S on the internet and I ordered 2 pieces.

I am planning to put them in a bass-reflex enclosure of 5.8L and tune this at 75Hz as this is what simulations advise.

So what's in the Tivoli is still unknown?


google > zaphaudio


For info on the Tangband W871's in br enclosure.
Zaph/John also has a newer favorite in that size range
with enclosures designed.


There's lots on the small TB's but after a variety of
tests on my own, I've only heard them right on
open baffle.


When put in a desktop size enclosure, they always
sound boxy and pretty much nowhere.


Here at DIY audio there was thread on using TB's
2 per enclosure with a tweeter facing upward and
a ported box. This looked to me like a
workable solution for a desktop style small
enclosure maybe mounted on lightweight stands which
would open up the sound.

Lastly, the earliest research I did on the TB's was
from _audioXpress_/_Speakerbuilder_ magazine in which
the TB's were installed in very small enclosures with
open backs. I never built those but all the enclosures
shown were quite small as well.


A TB designed with the "Bose effect" just crossed my mind
but I'd have to look it up. It was a VTL design meaning
a small cabinet with a folded line length.

Hi all
I had the Tivoli at the bed side table very close to my ears listening at very low level and I had observed that the middles were “dirty” and the bass excessive and boomy.
When listening from a distance and at higher level, these problems were not obvious (in fact boomy bass is an attribute that “sells” on this size of radios)
I opened it up, treated the cone with a dilluted plasticizer (two coatings), filled the internal volume of the box (not around the x-former) with fiberglass and stuffed the bass reflex tube with dacron.
Now, mids are much cleaner and bass not boomy but pronounced and tight.
Removing the protective screen from the front side of the speaker is another step forward.
Regards
George

I have both a Tivoli Model One and Boston Acoustics Receptor.
To my ears the Receptor is smoother sounding and has a more extended low end. If you want to reverse engineer something, I'd suggest targeting the Receptor instead of the Tivoli. In either case you can be sure that some type of EQ is also used. It is not just the box that accounts for the sound.

I was also quite sure that this is the case (judging from the amount of bass).
That's why I didn't bother running an impedance curve on the speaker-box combination and I applied the remedies in an experimental way instead.

Tivoli says as much in their sales literature.
