Seas Noferro-900 Visaton Waveguide WG-148R

4 Ω dome tweeter with waveguide

With the new WG148R Visaton has placed an excellently processed waveguide for 25 mm tweeters on the market. This was combined with the Seas Noferro-900, with excellent results.

To mount the Seas Noferro-900 to the WG148R you only have to widen the screw holes of the tweeter from 4,5 to approx. 6mm.

Directivity horizontal (0-90 ° in 15 ° steps)

Noferro900_W148R_Winkel

Due to the waveguide system-related symmetrical elevation in the frequency range from 1-10kHz.

The Seas Noferro 900 and the Waveguide WG-148R are a perfect match. Both mechanically and, and in particular acoustically. Directivity is extremly even, up to highest octaves. Just above 3kHz there is a slight widening. This can be further improved by clever connection to an 5-7 inch mid-bass driver. That behavior fitted perfectly with midrange speakers of the 15cm class. Crossover points around 2-3kHz promise excellent results.

It should be noted: The combination was measured in a maximum narrow baffle (17cm). Such is usually very beneficial for waveguides in terms of controlled directivity.

In the 2. Image, frequency response was roughly linearized by DSP. A shelving filter and a PEQ were set.

impedance

Noferro_WG148R_Impedanz

Flawless impedance.

Very accented, resonance peak at 900Hz, labeling the tweeter as ferrofluid-free.

Burst decay

Noferro_WG148R_Ausschwingen

Even and rapid decay over all frequencies. Perfectly.

Harmonic Distortions 85, 90 and 95dB

Noferro_WG148R_Klirr

The harmonic distortions are extremely low. Only at 10kHz scratched K2 at 95dB / m at the 1% mark ... inaudible. K3 and higher orders are negligible. Crossovers around 1,5kHz with> = 18dB / Oct can be realized without any problems.

Summary


The Seas Noferro-XNUMX with the Visaton Waveguide WG-XNUMXR measures itself ...

... excellent in all disciplines! There is not much more to say about that.

The sum of the EIAs is incidentally, in view of the results, hard to believeXNUMX € (WGXNUMXR: XNUMX € and NoferroXNUMX XNUMX €, as of October XNUMX).

    1. Hello eltipo
      Nice to read here from you.
      To your question: "Jein" ... Have measured only 6-8 Noferro-900. They were pretty neat in a + -1dB hose.

      By the way, I assume that models like Noferro-550 / 650 / 800, KT27-F (H0831-06), KT28-F (H0881-06), and KT27-800TV (H1210-06) work equally well on the WG148R, since you have the same front panel in my opinion.

      Best Regards
