Active subwoofer Morel Primo PSL10AE

\n\n

Morel's Primo SL subwoofers also form the basis for the active Primo SL AE enclosures, which combine a precise driver, a powerful amplifier and a compact construction into a single acoustically matched unit. The solution is designed for those who want genuinely deep, controlled bass without significantly compromising trunk space. The active version offers plug & play installation convenience without sacrificing the performance, control and musical accuracy for which Morel has long been renowned. The integrated 350 W RMS amplifier is not merely an add-on but a fully fledged power unit precisely matched to the driver's parameters. This enables the subwoofer to operate with maximum control, high efficiency and stability even at higher volumes. The result is dynamic, authoritative yet refined bass that retains clarity and structure even with demanding musical material.

\n\n

The enclosure itself is designed as a compact, acoustically optimized unit with a rigid, internally reinforced construction. The exterior is covered with a high-quality durable carpet with an embroidered Morel logo, which emphasizes the solution's premium character while preserving a clean OEM look. The design allows installation down-firing, up-firing or in a vertical position depending on the vehicle's available space. The subwoofer is protected by a stylish cast aluminum grille with the characteristic Lotus motif, providing high mechanical durability and reliable protection of the driver during everyday use. Thanks to quick-release power and signal connectors, the entire box can also be easily removed when full use of the trunk space is needed.

\n\n

The Primo SL AE therefore does not appear as a compromised space-saving solution, but as a sophisticated active system that combines compact dimensions, practical flexibility and full acoustic performance – in the typical spirit of the Morel brand.

RMS power of the subwooferThe RMS power of an active subwoofer is the constant power that the active subwoofer can play over a long period of time. We recommend following this value. The RMS power of active subwoofers is taken as the RMS power of the integrated amplifier, which in most cases is slightly undersized, which guarantees protection against subwoofer burning.	300 W
Maximum subwoofer performancePeak performance or Max. power that an active subwoofer can play for a moment (approx. 0.5 s), for example when percussion instruments are struck in a recording. But it is not as important a parameter as the RMS power.	600 W
RMS power of the amplifier	350 W
Energy class of the amplifierAmplifiers are divided into two basic classes: analog and digital . Analog amplifiers (A/B) have higher consumption requirements, but usually have a more natural sound. Digital amplifiers (D) have significantly lower consumption and higher efficiency, but the sound may not be as faithful as with classic analog amplifiers.	D
The diameter of the subwoofer usedThe diameter of the subwoofer that is installed in the active box.	10\" (250 mm)
Frequency rangeThe ability of the device to reproduce a signal from the lowest frequency to the highest, or the ability of an active subwoofer to faithfully reproduce sound in a specific frequency band. Professionally: In the frequency range from 40 to 16,000 Hz, the vast majority of fundamental and overtones (harmonics) of all musical instruments are found. We are interested in the course of the radiated sound pressure in this range of frequencies when the loudspeaker system is supplied with constant power. We call this course the frequency characteristic, which tells us the level of radiated sound pressure in decibels (dB) depending on the frequency. The frequency characteristic of a speaker or speaker system can be expressed most succinctly with a graph. Mostly, however, the frequency characteristic is indicated by indicating the maximum tolerance of the sound pressure in the given frequency range, e.g. 50 to 15,000 Hz -+ 6 dB. since the frequency characteristics of loudspeakers and systems in general are quite uneven, some manufacturers do not even specify this maximum tolerance of sound pressure in decibels for reasons of prestige. Data impoverished in this way is worthless. What is valid is that the manufacturer offers a speaker system with a frequency range of 30 to 20,000 Hz, if he is worried about stating the maximum unevenness of the sound pressure in this range, because he can have a tolerance of, for example, +- 20 dB. The unevenness, i.e. the undulation of the frequency course in good speaker systems for quality music performance should not exceed +-3 dB in the 80 to 12,000 Hz band and +-6 dB in the 40 to 16,000 Hz band. Greater unevenness already depletes or emphasizes certain tonal areas, which can cause audible or even disturbing distortion. The proportion between fundamental tones and higher harmonics also changes, thereby changing the color of the sound, and individual musical instruments as well as the entire musical image sound unnatural.	20 - 200 Hz
Low-pass filter (LPF)	50 - 200 Hz
High level inputThe high-level input on the active subwoofer enables connection directly to the speakers in the car without purchasing an external high/low converter. Use in the case of mounting an active subwoofer on the original car radio.	Yes
Automatic on and offThis function will facilitate your installation and solve the problem of finding a remote signal, which is sometimes a problem with original car radios. The active subwoofer with the Auto sense function can recognize that the equipment in the car is active and turn itself on. A useful and practical feature.	Yes
Bass boost functionBass boost or bass enhancement. With this function, the bass itself can be emphasized, at a high level of bass boost, the speakers and the subwoofer can distort a lot and the sound will be worse than better. We therefore recommend using the "bass boost" function wisely.	Yes
Phase rotation optionPhase shift is a linear electronic oscillator that produces a sinusoidal output. It consists of an inverting part of the amplifier such as a transistor. The feedback network "shifts" the phase at the output of the amplifier by 180 degrees to the oscillation frequency and gives positive feedback. The Phase shift filter produces a phase shift that increases with increasing frequency. This is usually used when the subwoofer sub-assembly is out with the magnet, or when two amplifiers are connected externally. Phase Shift is also used with active speaker wiring, where the time shift of the speakers is set. The point is that the subwoofer does not play the bass late, and for this reason better amplifiers offer this phase reversal option.	Yes
Protective gridProtective grids or bars, as protection against mechanical damage to the subwoofer.	Yes
Loudspeaker type	Sealed
Active subwoofer dimensions	460 x 338 x 165 mm
