Cheap and does the job.
Nickname - 1, 01.10.2018
I wanted these for some cheap little high-frequency in-fills overhead in the room, mostly as an effect. We're putting a lot of wattage through them and filtering HP at about 4k and they're coping fine. They're quite sharp at the mid frequency range (near to the bottom end of their stated range) so we'll probably need to EQ these a good bit more to take a bit of the ear-splitting harshness out. They're very directional as you might imagine, so if you want to use these you'll need to be mindful of your positioning.

The datasheets are very limited on these but I don't think that this is too surprising at this price.

The packaging was interesting: these speakers come in a little plastic bag with no documentation. But again, at this price, you can't complain about that.

The form-factor is quite rugged and I don't think that they could be physically damaged too easily which is nice.

Overall I would - and probably will - buy these again for the same purpose: as an in-fill for high frequency. They're very small and light and neat and tidy and can be hidden away without too much effort and mounted easily too.

Eine Lanze für den Piezo
Martin866, 20.10.2009
Piezo-Hochtöner genießen zwar keinen guten Ruf, trotzdem möchte ich hier eine Lanze für diesen Hochtöner brechen.

In meinen 2-Wege-Bassreflexboxen kamen schon seit Jahren pro Box zwei dieser Hochtöner von Monacor zum Einsatz. Da diese direkt parallel zum Basslautsprecher angeschlossen waren, ist immer mal wieder einer wegen zu hoher Spannung (>40V) gestorben. Nachdem ich zum Abblocken der tiefen Frequenzen ein RC-Glied mit -6dB/Oktave unterhalb von 4 kHz vor die Piezos geschaltet habe, ist keiner mehr kaputt gegangen. Allerdings klangen die Ersatzpiezos, die nicht von Monacor hergestellt waren, ganz fürchterlich schrill und hart und bestätigten damit den schlechten Ruf der Piezos.

Bei Thomann fand ich nun die Originale von Monacor und bestellte mal einen zur Probe. Ich kann nur sagen: der Mehrpreis gegenüber den im Internet angebotenen Nachbauten ist gerechtfertigt, der Klang deutlich weicher und ausgewogener. Deshalb habe ich gleich noch 5 Stk. nachbestellt und mir zwei als Reserve hingelegt.

Good tweeter and cheap (medium-low power)
danirebollo, 28.08.2012
Good mid-range tweeter.
Approximately linear response in the range of 3k to 18khz with resonance peak around 3k.
Treated paper diaphragm of about 3cm without coveralls. The central part is flat separated a few millimeters from the central axis coming out of the speaker; This favors omnidirectionality of the speaker and prevents to surpass the maximum excursion (protecting it).
It would be a good option to use as a high tweeter or tweeter considering your response (although in pro speakers usually does not matter much ...), and that its power is not high.


I bought this tweeter to integrate it into a 15 "bass hartke speaker (previous two-way filtering).

Tweeter ok
Olivier2635, 08.11.2014
For the price, glad to be able to replace a grilled tweeter to continue using old HP. Already 20 years of use and it always works ... so as long as the basses are working ...
