The Submonitor MKIII is the lower element of the Admonitor Première.
This allows more accurate low frequency extension and headroom.
The Submonitor was designed to be integrated with the Admonitor Première. Visual impact has been optimised by the use of 3 pieces, Nano-carbon 6.5” drivers.
Low frequency extension is the result of the EAARR “Enhanced Active Auxilary Radiator Reflex" loading system. The Submonitor is seamlessly integrated in the Admonitor Première by the mutational "Transfer20Z" crossover technology. Rather than being a generic subwoofer, the Submonitor 3 has been designed to blend seamlessly in the acoustic performance of the Admonitor Premiere, transforming these mini-monitors into a full scale reference 3.5 way system.
The transition between upper and lower module has been designed in such a way as to increase naturally the radiating surface to the lowest frequencies. The objective was not simply to have "more bass" but to have all the subjective advantages that the best reproduction of the quasi-infrasonic spectrum can bring; more complete tonal accuracy; better "hall" and ambience perception; higher dynamic headroom and ease on crescendos.
The 3 special 6.5” Nano-carbon woofers, with the very powerful and fast motors, optimize the specific piston surface versus physical impact of the Submonitor. The technical driver parameters allow a surprisingly extended low frequency reach, even if performance has been subjectively adjusted for optimal pace and drive.
The crossover on the Submonitor 3 has 2 overlap points one for the lowest notes at 45 Hz and one at 95 Hz, for crossing over to the Admonitor Premiere. The top of the woofers is mainly used to increase the radiating surface of the AGTi midwoofer, by working in tandem with it, while the 2 lower woofers only work on the lowest 2.5 octaves.
The EAARR loading system, "Enhanced Active Auxilary Radiator Reflex" substitutes the passive radiator of the previous Submonitor with the 2 lower 6.5” units that drive the traditional port in the same enclosure, to extract the best low frequency extension in compact enclosures.
The Submonitor 3 improves on the performance by upgrading the vent solution towards a quasi-aperiodic “laminar flow” type. This allows for a “faster”, better defined, reproduction of the lowest fundamentals. Also further the spurious noises, associated with airflow, are reduced.
Due to the complexity of low frequency room interactions, for optimisation purposes, it is possible to interface the Admonitor Première in different ways to the Submonitor:
- Using the upper modules with the internal crossover (high pass) of the Submonitor.
- Using the upper modules in "Bi-Wiring" fashion, by driving the tweeter input separately.
- Using the upper and lower modules in passive "Bi-Amping", by using a dedicated “termination dongle” on the Submonitor 3 satellite output.
- Using the upper and lower modules in active "Bi-Amping", with a low level passive crossover.
