The ZX series is our Premium range of loudspeaker systems. This Ultra High Performance series features 5 models. These are designed for the most discerning applications both in Touring and fixed install. Only high end and the best components are used in this series. We went to large extents to develop custom drivers along with our Driver manufacturer to get the desired results and timelines required by us. This series is designed as a no holds barred reference series to outperform the best in the market.

The ZX 12 and ZX 15 are full range high end Loudspeakers capable of handling 800W RMS of continuous power. Both use a custom HF Compression driver with a 1.4” Exit and 3” Aquaplased TC4 diaphragm. The ZX12 and ZX15 are capable of producing a SPL of 132db and 133db respectively peak acoustical output. Both these models have pole mount, fly points and a wedge for monitor use. The ZX15s 15” LF with a 4” voice coil and 220mm magnet diameter which is larger than that found in most subwoofers. It is sweet sounding even at a distance of 2m. It is ideal for both monitor or FOH use. The ZX15HP is a step up from the ZX15 and features all Neodymium components to reduce weight and increase efficiency and it has average sensitivity of 99db and 1000W RMS power handling capacity. It is capable of a peak acoustical output of 135db. The ZX 152 is a dual 15” two way top capable of handling 1600W RMS power. The 15” LF drivers use a high efficiency neodymium magnet to reduce weight and increase efficiency. It features Top of the Line performance and reliability along with highly dynamic and holographic reproduction of sound. This speaker is designed for applications requiring very high SPL without any compromise on fidelity. The ZX 153 is an incredible 15” 3 way loudspeaker system designed to be operated only in biamp mode via DSP. This is a high SPL, light weight loudspeaker using high efficiency neodymium magnets for all the drivers. It features an Aquaplased TC4 diaphragm for ultra smooth HF reproduction along with a Rotatable MFH horn with silk fiber loaded cone for incredible mids. This speaker is designed for high SPL applications where nothing but the best mid frequency and vocal reproduction will do.

Important Remarks
  1. Relative gain is only valid when all amplifiers have same gain.
  2. LR = Linkwitz-Riley, BW = Butterworth, BS = Bessel
  3. User can not change polarity
  4. User can not change crossover point between LF and MHF
  5. User can change crossover point between ZX153 and SUB
  6. Absolute minimum low cut values are:
    30Hz 24dB/oct for ZX153 LF
  7. Absolute maximum high cut values are:
    120Hz for SW218s and SW218sHP
    90Hz for SW121s
  8. Limiter settings can't be changed or you may break the drivers ! User can only lower threshold.
  9. Depending on subwoofer placement, user can change delay on subwoofer. But delay between ZX153 MHF and LF must always remain as specified.
  10. ZX153 may be used with or without subwoofer.
  11. To guarantee maximum performance, ZX153 should be installed and adjusted by a VAL Audio qualified engineer.
