Powerful Subwoofer in Box Hifonics Zeus ZSPL12DUAL
Massive subwoofer boxes have a long tradition at Hifonics. Double bandpass boxes, in particular, remain very popular among bass enthusiasts. Now, bass reflex system fans have their moment too. Two new ZSPL boxes expand the ZEUS SPL line with an affordable single and dual box, developed with one goal in mind - powerful performance! The similarity of the built-in ZSPL12D2 woofer to the ZEUS EXTREME line is immediately apparent due to the nearly identical surround, allowing the subwoofer a maximum excursion of +/- 26 mm. The high-quality carbon dust cap, which provides the diaphragm with additional stability and guidance, has also been borrowed. The powerful drive with a 64mm dual voice coil and heavy double magnet (3.4 kg) allows the ZSPL12 DUAL model a music handling capacity of up to 2400 watts.
The ZSPL12R model, with a music handling capacity of up to 1200 watts, places high demands on the amplifier. However, if the box gets enough power, the smile on the listeners' faces will last a long time. Strong deep bass, impressive even at extreme volumes, will delight every bass lover. Thanks to the 2+2 ohm impedance, the box can be connected not only to pure monoblocks but also to powerful two or four-channel amplifiers. If someone still finds the ZSPL12R box's performance insufficient, they will hardly find a better solution unless they opt for the monstrous ZSPL12 DUAL, which offers an impressive handling capacity of 2400 watts. Equipped with two 30cm SPL woofers, this dual-system monster delivers such powerful pressure and volume that it almost smooths out the wrinkles on your face. With an impressive weight of 42 kg and a width of 90 cm, it takes up the entire trunk. (There's only room for a case of beer on the back seat.)

| RMS powerThe RMS power of the subwoofer is constant power. This is also the performance of continuous use of the subwoofer. If you exceed the power for a longer period of time, irreversible damage or subwoofer voice coil burning! You can tell if the subwoofer is overloaded by the vibration of the subwoofer membrane. | 1200 W |
| Max. (maximum performancePeak performance , which the subwoofer can play momentarily (approx. 0.5 s), for example when hitting drums in a song. If the maximum power is exceeded, damage can quickly occur or subwoofer voice coil burning! | 3600 W |
| The diameter of the subwoofer in the box | 300 mm (12\") |
| ImpedanceImpedance - measurement of electrical resistance. When buying a subwoofer, it is very important that everyone make sure that the impedance is compatible with the amplifier that you are connecting to it. For subwoofers with a double voice coil, we recommend following the information in the advice center! Example: A 2 Ohm subwoofer cannot be connected to an amplifier that is only stable up to 4 Ohms. A 4 Ohm subwoofer can easily be used with an amplifier that is stable up to 2 Ohms. Connecting a 4 Ohm subwoofer to an amplifier that is stable up to 4 Ohms also without problems. The most common subwoofer impedance is 4 Ohm. Example: A 2 Ohm subwoofer cannot be connected to an amplifier that is only stable up to 4 Ohms! A 4 Ohm subwoofer can easily be used with an amplifier that is stable up to 2 Ohms. The most common impedance of subwoofers is 1 x 4 Ohm. | 2 x 4 Ω |
| Loudspeaker typeThe closed enclosure is characterized by a simple construction. Closed enclosures are usually smaller than bass-reflex enclosures, and a special damping fleece is used for their damping. A closed baffle has the advantage of preventing an acoustic short between the front and back radiation of the subwoofer diaphragm. The disadvantage is that the closed enclosure raises the natural resonance frequency of the used subwoofer and thereby also increases the lower limit frequency. This is because the back side of the diaphragm is forced to compress and dilute the air inside the enclosure when the subwoofer is radiating in a closed enclosure. This adds to the inherent stiffness of the subwoofer's oscillation system the stiffness of the air in the closed enclosure. This causes an increase in the stiffness of the oscillating system and thus an increase in the resonant frequency of the entire system: subwoofer -> loudspeaker. The increase in resonant frequency for a given subwoofer is greater, the smaller the volume of air in the closed enclosure. The relatively small volume of air in the closed enclosure acts on the subwoofer as an acoustic spring when radiating the back side of the membrane into the enclosed enclosure. USE: Mainly for quality bass listening in the entire band with an emphasis on detail and accurate reproduction in the lower band. Pros and cons: + pure reproduction + small closets + easier tuning - low level of efficiency in deep bass - loudness only at the cost of enormous deflection of the diaphragm - a significant acoustic pressure cannot be expected The bass reflex enclosure is designed in the same way as a closed enclosure, but it also has a so-called bass reflex mouthpiece, or "bass reflex". Needle foam is used to dampen bass reflex enclosures. USE: The ideal use is in cases where the listener wants to achieve a high volume and a good sound pressure level. It is the best compromise between sound quality and performance and is also the most commonly used Pros and cons: + good efficiency in deep bass + a small deflection of the membrane is enough for a large volume - reproduction less accurate than with closed enclosures | Bandpass |
| What is the baffle made of?Subwoofer enclosures are usually made of 18-22 mm MDF board or pressed chipboard. Due to its higher strength, MDF board is a better material than ordinary chipboard. | MDF |
| Dimensions of the boxEnclosure dimensions are given as height, width and depth, which is often longer at the bottom edge than at the top, due to the bevel of the rear wall. | 90 x 38 x 48/38 cm |
| Box weight incl. subwoofer | 42 kg |
| Beveling of the back wallThe bevel of the back wall is a crucial parameter if you intend to place the subwoofer in the luggage compartment, instead of the back wall of the rear seat. This will save you a few centimeters of space in the trunk of your car. | Yes |
