“Displacement is irreplaceable”
The premier class calibre of 38 cm/15 inches has been used in the woofer. We did not want to compromise on size at the heart of the Transpuls 1500. But it is not only the diameter of the woofer that determines the bass power and dynamics; for perfect functioning, the internal volume also has to be precisely defined and implemented structurally. The woofer operates in a special bass reflex housing ( CRA = Controlled Reflex Alignment ). The dimensioning of the dampened bass reflex port has been designed in such a way as to combine the advantages of bass reflex and a closed housing. Goal: More precise, deeper bass with high efficiency.
In addition to a large, lightweight membrane, the 17 cm midrange driver also has a closed basket. This means it is designed as a pure midrange speaker.
Another special feature is the tweeter. Like a lot of studio and historical class speakers, the treble range is taken care of by a horn. The Transpuls 1500 horn tweeter has not only been designed as a slot radiator for a defined dispersion angle, it also has 2 (!) drivers in one horn, which results in higher load capacity and is the reason for the angled position of the tweeter membranes in the neck of the horn. We call this design the Double Compression Horn. Because of the intentionally controlled dispersion characteristics of the overall speaker, a slightly angled position should be chosen when the speakers are placed far apart. This is why the enclosure is not of an exaggeratedly deep design. The crossover uses 12/18db filtering with phase correction.
Looks without any inferiority complex
The sturdy MDF enclosure in a dark wood grain finish with a black baffle provides optimum acoustic playing conditions for the speakers used.
Combined with the sturdy, removable fabric cover and the elegant solid-metal logo plate on the base of the speaker, the Transpuls 1500 exudes the charm of the great classics of loudspeaker design.
One speaker for a lot of amplifiers
Its high efficiency and good-natured impedance curve makes the Transpuls suitable for a very wide range of amplifiers.
