The new CS 300 s4 Cento subwoofer is the perfect enhancement to every sound system, to fully enjoy the authentic Hertz Sound Experience!
The R & 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 32 l. for the 30 cm (12 in.) CS 300 model.
The 4 Ω 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.
The 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.
An innovative system of dynamic fluid optimization and turbulence reduction, obtained thanks to the spider support acting as an air conduct towards the venting holes on the basket, drastically reduces the acoustic distortions generated by the air compression at high excursions.
The cone geometry, the suspension and the spider have been designed using FEM (Finite Element Method) simulations to obtain the best performance configuration that guarantees control and low distortions even at high mechanical excursions of the mobile group.
The terminal block uses solid push connectors that accept cables up to 8 AWG to offer low wiring resistance and maximum ease of connection even in installations with multiple subwoofers.
The subwoofer is also provided with an elegant high resistance ABS plastic gasket that allows the grille to be fixed to finish the installation.
The optional CG 300 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.
With the Cento subwoofers even the younger enthusiasts will enjoy an exciting reproduction of low frequencies in the car!

The PERFECT bra!
Size: 38D, Color: Barely Buff
I typically don't write reviews...but I just had to with this bra! I have not worn an underwire bra in years. I have had such a hard time finding something that is comfortable, supportive and does not allow for overflow. This bra is perfect! The material is soft and stretchy. It covers everything and does it comfortably! It also provides a perfect lift! The color is a perfect skin tone. Pretty sure I will be buying more!

Stylish and practical backpack for work and travel
Color: Upgrade-apricot, Size: 15.6 Inch, Color: Upgrade-apricot, Size: 15.6 Inch
For both everyday work and travel, this bag has proven to be an excellent option. I can feel secure bringing my computer around because to the 15.6-inch laptop compartment's solid fit and ample padding. Notebooks, chargers, and a few personal belongings can fit in the spacious main compartment without feeling crowded.
The apricot color looks polished but still casual enough to wear outside of work, and I really enjoy the sleek and fashionable shape. Even when the bag is completely packed, the straps remain comfy, and the stitching seems sturdy.
I particularly enjoy that there are several pockets, including smaller ones for a phone, pencils, or keys. It makes everything accessible and well-organized. If the material gets a bit dusty while traveling, it washes clean and the zippers open smoothly.
It is lightweight, adaptable, and functions well as a carry-on, purse-style bag, or business backpack. All things considered, it's a good everyday bag that is both practical and stylish.

Perfect for a backpack or a purse
Color: Upgrade-black, Size: 14 Inch, Color: Upgrade-black, Size: 14 Inch
I love this black backpack. It has gold zippers and brown accents and it has a pocket in the front two on the side three inside and a pocket on the back of the laptop pocket. I have a disability and have to carry extra stuff so this is a perfect size for me to wear in my back every day. It’s black nylon so it should stay clean. I tend to drop things. I think this will be great, but even without a disability, this is a great backpack. It’s so cute.

Perfect day bag!
Color: Upgrade-black, Size: 15.6 Inch
Super convenient and lightweight. I used it for two back-to-back conferences last week and it was PERFECT for what I needed to tote along all day. Fits my regular sized computer (15-16 inch) and even held my water bottle (which is larger than a regular plastic water bottle).
