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!

good/bad HP Chromebook 15" Intel N200, 8GB DDR5 RAM, 192GB Storage
Capacity: 64GB eMMC+128GB SD Card
As I just received this Chromebook this is my review. Likes: its much faster than my old Chromebook which is a Acer about 10 years old. I like the big screen vs my old 14". good color and definition. HATE:The lightly colored letters. It is near impossible to read in low light and even in medium light. I have already ordered new stick on letters to make it more visible. HP you should have done a better job than this. This really detracts from the enjoyment of using this Chromebook. It is terrible. I can't give it 5 stars because of this problem.I would have liked another port for plug ins like mouse or thumb drives. Otherwise I love it.

Excellent for the price!
Capacity: 64GB eMMC+128GB SD Card
So far so good. Considering I got it primarily for browsing and smaller tasks, it's worrying perfectly so far. Boots up very fast, runs very smooth, and so far I'm happy with the battery life. I do wish I had thought about making sure it had a keyboard light but that's still mostly not a problem for me. I also like how simple it was to set everything up and get it synced with my google account and phone.

Chromebooks are a great concept. They're laptops without the bloat.
