Seas Noferro-900 Visaton Waveguide WG-148R
Directivity horizontal (0-90 ° in 15 ° steps)
|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.
Sound pressure standardized at angles to 15 °
Very pronounced resonance peak at 900Hz, which is characteristic of a ferrofluid-free tweeter.
|Even and rapid decay over all frequencies. Perfectly.|
Harmonic Distortions 85, 90 and 95dB
|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.|
The Seas Noferro-XNUMX with the Visaton Waveguide WG-XNUMXR measures itself ...
... excellent in all disciplines! There is not much more to say about it.
The sum of the EIAs is incidentally, in view of the results, hard to believeXNUMX € (WGXNUMXR: XNUMX € and NoferroXNUMX XNUMX €, as of October XNUMX).

Can you say something about the consistency of the NF900 series?
Nice to read here from you.
To your question: "Yes and no" ... I only measured 6-8 Noferro-900s. They were pretty neat in a + -1dB tube.
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.
Hello, please which Nudeo 900 with waveguide?
I used the hypex asxnumx, but did not save the filters. So unfortunately I can not answer this question.
Very interesting read. The scan D2606-922000 looks like it's on the front of the car with the 4 mounting holes on a 94mm pitch!
I've seen that some tweeters have recounted the front plate while some stick out from above the front plate (the vison G 25 FFL comes to mind here) this aspect?
Could the SEAS H1147-06 (27TBC / G or the Seas Prestige 27TBFC / G with this waveguide…. Or maybe the WG300 is better?
I don´t know… Sorry 🙂
