Subwoofer Crunch CRB350

Crunch CRB350 is a compact subwoofer system in a bass-reflex enclosure designed to provide a basic upgrade to the audio system with a more pronounced bass component. The enclosure houses a 12\" (300 mm) subwoofer with a characteristic multicolored cone and a prominent decorative center with the brand logo. The design uses a ribbed rubber surround that helps stabilize cone movement under higher loads and contributes to long-term reliability. The subwoofer is equipped with a 50 mm voice coil and is protected by a pair of chromed protective bars that prevent cone damage when handling items in the trunk. The sturdy enclosure with a bass-reflex port helps increase system efficiency and support a more pronounced bass response. Thanks to its compact dimensions the system is primarily suitable for standard installations in the trunk of passenger vehicles.

About the brand

Crunch has been active in the car audio market for more than three decades. The brand originated in the United States in the 1980s and gradually established itself among manufacturers of affordable audio equipment intended for everyday and less demanding installations. Later, the brand became part of the American Maxxsonics USA group, which also includes other well-known car audio brands such as Hifonics, MB Quart and Autotek. Within this group Crunch has long been positioned as a budget-friendly alternative focused on simple and functional solutions for enhancing and expanding factory audio systems. Crunch’s range includes a wide portfolio of amplifiers, speakers, subwoofers and accessories offering good value for money.

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.	350 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!	700 W
The diameter of the subwoofer in the box	12" (300 mm)
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.	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	Bass reflex
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.	375 x 385 x 460/350 mm
Box weight incl. subwoofer	14 Kg
