Beyma TD-164: TD-series horn rated 60 W AES for compact two-way tops
The Beyma TD-164 is a horn from Beyma's TD series, built to sit in front of a compression driver and rated at 60 W AES. At 1 kg it is on the heavier side for its size class, which points to a stiff, well-damped body of the kind you get from metal or thick-walled cast horns. That matters in the HF section: a horn that does not ring along at high levels adds less colouration and stays clean on transients.
42.audio also lists the TD-164P, which carries the same power rating at a fraction of the weight. Choosing between the two is essentially a choice between mass and weight saving. The basic idea – controlled, even high-frequency coverage for PA and installation work – is shared by both members of the TD range.
Use and enclosure
The natural home is the HF section of a two-way top or an installation cabinet: the compression driver supplies the acoustic output, the horn provides directivity and acoustic loading. Before buying, make sure the horn throat matches the driver exit. Beyma offers matching sizes across its horns and waveguides and its compression drivers – check throat diameter and bolt pattern in the 42.audio driver database before pairing.
The 60 W AES figure describes what the horn is designed for; in practice the driver sets the real limit. The driver, together with the horn mouth, also determines the lowest sensible crossover point: the smaller the horn, the higher you should cross over, because pattern control is lost towards the bottom and the driver starts to move without horn loading. A steep high-pass of 12 or 24 dB per octave and a safety margin above the driver's resonance protect the voice coil.
What to look out for
- Power rating 60 W AES – the real limit is set by the compression driver you mount, not by the horn.
- Weight 1 kg: a quiet body, but allow for it in baffle thickness and fixings.
- Match throat size and bolt pattern of the driver before ordering – horn and driver have to fit each other.
- No datasheet PDF on file – confirm coverage angles and dimensions via Beyma documents or the driver database.
Frequently asked questions
What is the difference between the TD-164 and the TD-164P?
Both are rated at 60 W AES and belong to the same series. The TD-164 weighs 1 kg, the TD-164P only a fraction of that – the difference is the body material. Mass favours the TD-164 for fixed installs, the weight saving favours the P version for portable boxes.
Which compression driver fits the TD-164?
A driver from the Beyma range whose exit diameter matches the horn throat. As no datasheet is on file here, verify the throat size in the 42.audio driver database or with the manufacturer before you order.
How low can I cross over with this horn?
That depends on horn size and driver, not on the horn alone. Rule of thumb: well above the driver's resonance and within the range where the horn still controls the pattern – with compact horns that means higher rather than lower.
Beyma TD-164: manufacturer, spellings and classification
Beyma and Acustica Beyma refer to the same manufacturer: Acústica Beyma S.L. of Moncada near Valencia, Spain. The TD-164 is a horn / waveguide from the TD series, available from 42.audio, Beyma dealer in Germany, with datasheet and full specifications in the driver database.
At 42.audio you get the BEYMA TD-164 with all key data in the driver database. More drivers from this manufacturer: Atlas Beyma.
