Additionally, thanks to the use of large voice coils and its low resonant frequency, the HELIX IK S series delivers an absolutely stunning bass performance, which is in no way inferior to larger dimensioned woofers.\u003c\/p\u003e\n\u003ch4\u003eSmart down to the very last detail\u003c\/h4\u003e\n\u003cp\u003eThe enormously stiff sandwich paper cone in conjunction with our heavy-duty drive system easily converts amplifier power into powerful sound pressure without any compression effects, while simultaneously demonstrating finesse when it comes to more subtle beats. A special highlight: the magnet system has a threaded hole on the back and thus allows the woofer to be fixed to the back panel of the enclosure. Since every millimeter of depth counts in flat constructions, enclosure vibrations are effectively reduced - even with thin walls.\u003c\/p\u003e\n\u003ch4\u003eFlexible connection\u003c\/h4\u003e\n\u003cp\u003eDesigned as a 1 x 2 Ohms (SVC2) or 2 x 2 Ohms (DVC2) variant, you can find the right low bass specialist for any amplifier configuration to get the maximum performance out of it.\u003c\/p\u003e\n\u003ch4\u003e\"All inclusive\" for self-made enthusiasts\u003c\/h4\u003e\n\u003cp\u003eIn addition to the high-quality connection terminal with gold-plated screw terminals, a solid protective grille and gasket are also included.

The R \u0026amp; D team, always at the forefront in the search for innovative solutions, with unfailing effort, succeeded in obtaining very powerful bass frequencies from ultra-compact sealed enclosures, optimizing all the electroacoustic parameters according to the target set: high performance with boxes starting from 16 l. for the 25 cm (10 in.) CS 250 model.\u003cbr\u003e\u003cbr\u003eThe 2Ω single voice coil configuration offers maximum compatibility with any type of amplification and an enclosure that houses more than one subwoofer. The reduced depth, the compact magnetic group and the lack of rear decompression hole allow the box to be shaped around the subwoofer obtaining a depth close to the one of a speaker for maximum freedom of installation on any type of car.\u003cbr\u003e\u003cbr\u003eThe special cooling system of the six-layer voice coil keeps the operating temperature within an optimal range even in case of extended listening sessions at high acoustic pressure.

The optional CG 250 grille in robust black metal mesh provide total protection for the subwoofer and an appealing look thanks to the Hertz diamond aluminium logo for better integration into the car.

Additionally, thanks to the use of large voice coils and its low resonant frequency, the HELIX IK S series delivers an absolutely stunning bass performance, which is in no way inferior to larger dimensioned woofers.\u003c\/p\u003e\n\u003ch4\u003eSmart down to the very last detail\u003c\/h4\u003e\n\u003cp\u003eThe enormously stiff sandwich paper cone in conjunction with our heavy-duty drive system easily converts amplifier power into powerful sound pressure without any compression effects, while simultaneously demonstrating finesse when it comes to more subtle beats. A special highlight: the magnet system has a threaded hole on the back and thus allows the woofer to be fixed to the back panel of the enclosure. Since every millimeter of depth counts in flat constructions, enclosure vibrations are effectively reduced - even with thin walls.\u003c\/p\u003e\n\u003ch4\u003eFlexible connection\u003c\/h4\u003e\n\u003cp\u003eDesigned as a 1 x 2 Ohms (SVC2) or 2 x 2 Ohms (DVC2) variant, you can find the right low bass specialist for any amplifier configuration to get the maximum performance out of it.\u003c\/p\u003e\n\u003ch4\u003e\"All inclusive\" for self-made enthusiasts\u003c\/h4\u003e\n\u003cp\u003eIn addition to the high-quality connection terminal with gold-plated screw terminals, a solid protective grille and gasket are also included.

theme with every completed project has been wondering \"what if we had used that different amplifier\" or \"how would it sound with those other speakers\".  I've learned to embrace being a gearhead

These versions are for the right-hand drive version of Mercedes-Benz.\u003c\/p\u003e\n\u003cp\u003eThe IR-MBZSUB82 subwoofer was designed with a 2-ohm impedance making it highly efficient when used with OEM amplification.
