JL Audio Gotham G213 V2 Subwoofer Review

Florida-based JL Audio products are popular and well-known among audio and hi-fi enthusiasts. Founded in 1975, this American company manufactures audio and hi-fi equipment for homes and cars. They have received numerous awards and international recognition, the speakers, amplifiers and subwoofers are made with a lot of their own development, 14 American patents are associated with the brand name. The company mainly prefers closed system products, the amplifier circuit was also developed by them. They use technological developments that guarantee the optimal operation and performance of the active subwoofer.

One such development is the design of a basket that also includes a rugged front panel, or even DMA technology, which controls the operation of the speaker motor, namely by ensuring that the diaphragm maintains its linearity over the entire range of motion.

JL Audio Gotham G213 V2 model

The polished MDF housing of the active, closed-system, front-emitting G213 V2 subwoofer is made with stable, rugged and durable technology. There is a status LED on the front panel, it also has automatic shut-off and standby modes, as well as MOSFET stages and LFE input. The subwoofer has a diameter of 2×345 mm and the subwoofer measures 546 x 867 x 610 mm, and weighs 163 kg! Due to the huge weight, it is worth carefully considering where to place the subwoofer, preferably for larger rooms. Frequent moving and relocation may not be possible for the extra weight device.

There are many fine-tuning options on the front panel. It operates with a “D” class amplifier with a power of 4500 Watts and a frequency transmission between 19-112 Hz. It is also equipped with an IFC power cable and of course a foot, XLR output can also be found on it. The device is hand-made and the speaker is protected by a grid. Measuring microphone helps to make precise settings, low-pass filter and crossover control functions are also available, phase polarity and power can also be controlled. We also have the option of EQ settings. In terms of design, the speaker box is elegant and very beautiful.

An 18-band room optimization system helps with integration and setup. The DARO digital room optimization system has proven to be extremely useful and performs settings with great precision. The subwoofer also has an unbalanced RCA input and Neutrik Combo XLR / TRS balanced bases. The casing is a solid fiberglass composite in a glossy black and stainless steel alloy. A driver with JL Audio technology was used in the production of the subwoofer, complete with a new signal processing DSP system.

We tested this subwoofer with a huge weight and performance!

We chose louder rhythm music to test the subwoofer. We took out the album of the classic rock band, Guns ’n Roses. We connected the subwoofer with an Anthem amplifier and Klipsch stationary speakers.

Producing a dynamic, detailed, nuanced and spatial sound, the incredible clarity and power this subwoofer impressed was impressive. As it is very large, it is by no means recommended for smaller or medium sized rooms. Its appearance, on the other hand, is very stylish and elegant, so there is no need to hide it. Controlled, guided bass ensures maximum sound. The dynamics were quite simply impressive, and even when connected to multi-channel systems, Gotham’s production is unique. Its controls and automatic room optimization are essential and very practical features. As it has very serious performance, it is definitely necessary to pair it with speakers of the same power and category for ideal performance. This reference subwoofer is also high on the cutting edge in terms of music, but its price is very high.

The room where the test was conducted was a 38-square-foot living room, the acoustics were improved not only by sound-absorbing and diffuser elements on the walls and ceiling, but also by the thick, acoustic curtains placed in front of the windows and glass door to optimize the sound.

The smaller model

The JL Audio Fathom F113 V2 subwoofer was also tested in another test. Like the Gotham model, it has a multi-band equalizer. The theme of room acoustics is related to the Schröder frequency, which is connected to a transition point between 200 and 300 Hz, above which there can be a lot of reflection in a room, which can be determined by acoustic measurements.

Above a certain frequency, the sound can be distorted by reflections. This should definitely be handled, the best way to handle it is to use wall and ceiling panels. Electronic or digital corrections are only effective if the acoustic conditions in the room are ideal.

The weight and dimensions of the Fotham are also smaller than the weight of the Gotham, so we would prefer this type for smaller or medium sized rooms. Its price and performance are also lower than the heavier model. 3000 Watts is the power of the built-in amplifier, it weighs 60 kg. The frame is made of rigid cast aluminum and is manufactured together with a strong magnetic system. Strong magnetic systems such as those found in this type tend to generate too much heat, which can cause distortion or malfunction. To avoid this, JL Audio uses a cooling system that delivers cool air directly from the openings above the top plate to the speaker coil, further enhanced by radial cross-drilling technology, which in addition to improving heat dissipation and energy management. it also improves sound quality and linearity by minimizing dynamic parameter shifts and compression losses.

We could experience extended low ends in his listening, in terms of dynamics we would clearly prefer to bring out the Gotham model as the winner.
