Beyma PRO65ND 6.5" Competition Series 200 watt 4 ohm Midbass/Midrange Speaker

BEYMA PRO 65ND - 6.5" NEO MIDRANGE SPEAKER

Description:

Integrated in the Competition line, these speakers have been developed from some of the most demanded models all over the planet by the Car Audio market in Beyma’s professional line.

The PRO65ND loudspeaker has diameter of 6.5" and is capable of handling very high power: 100 Wrms. Thanks to the special design, optimized to reproduce the midrange frequency, the loudspeaker offers high sensitivity in all models that are around 100 dB.

It’s important to emphasize that although this loudspeaker seems physically intended for woofer or subwoofer; this speaker is not designed to reproduce that frequency range. Meaning we could break it quite easily if we intend to give it such use.

On the contrary, if we use it to reproduce the frequencies for which it is designed, this speaker can generate very high levels with great high quality playback. But always as part of a system in which there also woofers and/or subwoofers to complement it and reproduce the lower frequencies where the midrange loudspeakers, with it’s special design, can’t.

The cutoff frequency recommended for these speakers not only have to take into account the frequency range, but also the impedance curve of each one of them. Based on these data the recommended cuts would be the following:

PRO65Nd:

• Minimum lower cutoff frequency (High Pass): 400Hz
• Maximum upper cutoff frequency (Low Pass): 5-6 kHz

Higher cutoff frequencies allow greater tolerance, but it is very important to respect the lower ones too. Also, the filtering should have a minimum slope of 12dB per octave (second order filter).

About Beyma

Since 1969 Beyma has been manufacturing extremely high-end speaker systems from its factory in Valencia. These products are create by some of the best audio engineers who enjoy good sounding music. Do not compare Beyma to other brands who import speakers from China. Beyma produce a wide range of solutions in the loudspeakers field. Their products are all underrated. You can amplify any of their speakers with 2 times the amount of the rated power, and they will easily handle all the power!

The accumulated experience as manufacturer of loudspeakers together with their famous Research & Development team have been the key to their success.

Beyma owns and maintains multiple show car vehicles. Their show cars actually use mostly the cheaper Beyma products in them. Their show cars are known to have the cleanest sound. They sound just as good from 200 feet away as if you were sitting in the car. That is the type of quality and engineering that goes into every Beyma product.
