The Reference flagship: flagship architecture, more accessible materials and four HPF woofers
Perlisten R7t is the flagship 4-way R-Series floorstander, with a three-dome 26 mm silk DPC Array and four 165 mm HPF woofers.
R7t follows the architecture of S7t without its most costly materials. Reference Series replaces the 28 mm Beryllium/Textreme TPCD array with three 26 mm silk domes and uses 165 mm HPF woofers: this material strategy, rather than a simple reduction in size, defines the different level of the two ranges.
Key features
- Reference R-Series design using technology derived from S-Series.
- 4-way architecture configurable as bass reflex or acoustic suspension.
- DPC Array with three 26 mm silk domes.
- Four 165 mm woofers with HPF diaphragms.
- 90 dB sensitivity and 4-ohm nominal impedance.
- Typical in-room extension down to 19 Hz in bass reflex.
- Recommended amplifier power from 100 to 400 W RMS.
- THX Dominus and THX Ultra certification.
Reference DPC Array: the same idea, different materials
R7t uses three 26 mm silk domes in its DPC Array to control directivity and maintain R-Series timbre matching. S7t moves to 28 mm drivers with a Beryllium tweeter and Textreme TPCD midrange domes: the concept is related, but the transducers place the two models at different levels.
165 mm HPF woofers
The four woofers use HPF, a proprietary pulp combining long-fibre hardwood, bamboo and wool to balance stiffness, mass and damping. S-Series instead uses 180 mm Textreme TPCD cones, so R7t transfers the flagship approach to a more accessible material platform.
Reflex or sealed alignment
The cabinet can operate as bass reflex or acoustic suspension. In reflex mode rated response reaches 27 Hz at -10 dB and typical in-room extension falls to 19 Hz; sealing the ports changes low-frequency behaviour, providing another way to adapt the loudspeaker to room and placement.
Scale, power and certification
At 48 kg, with 90 dB sensitivity and recommended amplifier power up to 400 W RMS, R7t is the Reference model for larger rooms. THX Dominus and THX Ultra certification confirm cinema-scale dynamics while retaining a strong two-channel role.
