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 the 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
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
It sounds balanced, sovereign and ready to do bad things when it comes to mean levels ... profound and dynamic bass ... discoloration-free mids ... The ring radiator ... unobtrusive and extremely smooth with a profound level of detail that only gradually draws attention to itself.
Conclusion
Clever driver combination, paired with perfect tuning, results in a box that does everything right.
Tweeter: Peerless XT25 TG-30 / 04 (Vifa XT300 K / 4) / Test
Alternatively: Scan Speak R 2604 / 832000
Woofer: 2x Monacor SPH-175HQ
Klang & Ton 06 / 2012: The SPH-175HQ passed our test course with bravura... Very high-quality driver, which cuts a good figure both in two-way constructions and as a low-frequency specialist

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.
XT25TG-30 / 04 Sound pressure at angles
System-related exaggeration in the frequency band of 1-7 kHz. Due to its symmetry, this can be easily equalized with the crossover. It is the purpose of a sound guide to act as an acoustic amplifier. The Vifa XT-300 (XT25TG-30/04) is an excellent match for the waveguide. Extremely even bundling without any disturbances worth mentioning. Due to the large dome (30mm voice coil), a slightly stronger directivity from 8kHz. Recommendation: plan a slight increase> 8kHz in the high frequency on axis.
XT25TG-30 / 04 Sound pressure standardized at angles to 0 °
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
Minimal delayed decay by 2kHz. Otherwise perfectly.
XT25TG-30 / 04 harmonic distortions
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.

Conclusion
The Peerless XT25TG-30/04 and the Waveguide WG-300 are a very attractive combination for extremely level-stable installations, for example in the home theater. Can be used from 1,5 kHz. I think I'll test it out in Cinetor.
