Specifications

  • Impedance: 4 Ohm
  • Sensitivity (2,83V/1m): 89 dB
  • Dimensions (HxWxD): 1100 x 238 x 361 mm
  • Crossover frequency: 1650 Hz
  • Frequency range (-3dB): 36 - 40000 Hz

Applications

  • High-grade stereo applications
  • Home theater as well without subwoofer
  • "Relaxed listening"
  • free placement

Characteristics

  • extremely neutral frequency response: + -1,25dB of 50-23.000 Hz
  • Exceptional bass depth (-3dB 36Hz, -8dB 30Hz)
  • D'appolito arrangement => Intensive spatial representation of sound
  • Both horizontally and vertically very well balanced frequency response at angles
  • low distortion, flawless burst-decay
  • optionally closed-box, bassreflex or a combination of both
  • => Very adaptable, even in "complicated" rooms

Test in Klang & Ton 04 / 2013 (excerpt)

Perfectly matched equipment: High-quality woofers and the ringradiator play together as built for each other.

measurements

Samuel HQ Angle Measurement 0-45 °
Klang & Ton measurement 0 °, 15 °, 30 °, 45 °

Flawless: On axis frequency response is in the range of plus minus one decibel from fifty hertz to over twenty kilohertz - the -3dBPoints are at 36 Hertz and 40 Kilohertz ...

listening

Balanced it sounds, sovereign and quite ready for acts of deception, which concerns common levels ... profound and dynamic bass ... discoloration-free mids ... The ring radiator ... unobtrusive and extremely supple with a subtle detailing that only gradually draws attention to itself.

Summary

Clever driver combination, paired with perfect tuning, results in a box that does everything right.

Test Peerless / Tymphany XT25TG-30 / 04 (XT-300 / K4) at the waveguide WG-300 / PCT-300 4 Ω ring emitter with waveguide

Datasheet © www.heissmann-acoustics.de
Measurements in 20x40cm baffle, 10mm rounded, in 70cm distance at 2,83V. Level scaled to 1m.

The Waveguide was milled with a CNC adapter plate mounted on the tweeter.

XT25TG30_04_WG

XT25TG-30 / 04 Sound pressure at angles

Vifa XT-300 (XT25TG-30 / 04) WG300 Sound pressure at angles

System-induced overshoot in the frequency band of 1-7kHz. This can be due to their symmetry very easy to equalize with the crossover. It is the purpose of a sound guide to act as an acoustic amplifier. This results in a more uniform bundling and higher load capacity. The Vifa XT-300 (XT25TG-30 / 04) fits perfectly with the waveguide. Extremely uniform bundling without significant disturbances. Due to the large dome (30mm voice coil) slightly stronger directivity from 8kHz.Recommendation: On the axis a slight increase> 8kHz in the tweeter schedule.

Here, the frequency response was linearized on axis. The 2. Picture (sonogram) clearly shows the excellent uniform straightening behavior of the combination of XT-300 and the waveguide.

XT25TG-30 / 04 decay behavior

Vifa XT-300 at Waveguide WG-300 decay behavior

Minimal delayed decay by 2kHz. Otherwise perfectly.

XT25TG-30 / 04 harmonic distortions

Vifa XT-300 at the waveguide WG-300 harmonic distortion

As expected, the distortion decreases compared to the variant without waveguide. The XT-300 already showed very good distortion even without waveguide, but with a significant increase of K2 under 3kHz. With Waveguide the effect is also present but attenuated by about 5dB. In sum, very low distortion. Even with 100dB, everything from 2kHz remains below 1%. K3 moves at the measurable limit.

Summary


The Peerless XT25TG-30 / 04 and the Waveguide WG-300 are a highly attractive combination for extremely low-level installations, eg in home cinema. Can be used already from 1,5kHz. I think I'll test that in Cinetor.
