PRIMA 10" ACTIVE SUB BOXThe Prima APBX 10 AS2 active subwoofer, with the 10 inch driver, features a dedicated high performance amplification module that enhances all the passive box technologies, such as the 2S(2 Sides 2 Sounds) design, the Plug & Play terminal block and ultra compact size. The amplification module, with power outputs of 400W RMS, is developed with he li technology (high efficiency low impedance), which thanks to the absence of the DC DC voltage booster
The Prima APBX 10 AS2 active subwoofer, with the 10-inch driver, features a dedicated high-performance amplification module that enhances all the passive box technologies, such as the 2S²(2 Sides / 2 Sounds) design, the Plug & Play terminal block and ultra-compact size. The amplification module, with power outputs of 400W RMS, is developed with he-li technology (high efficiency / low impedance), which thanks to the absence of the DC-DC voltage booster reaches the impressive 90% efficiency level, very close to the theoretical limit of the D-Class. New input stage DBT (Dynamic Bass Tracking) technology allows 100% use of the he-li (High-Efficiency Low Impedance) amplifier power and to enjoy a tense and dynamic bass even at very high listening volumes. Eliminating the voltage booster was made possible thanks to the development of the new dual coil drivers, which inherit all the technological background of the Prima subwoofers, but differ for the ultra-low impedance (0.16 ohms for APBX 10 AS). This feature ensures a perfect synergy with the he-li (High-Efficiency Low Impedance) technology, maximizing the combination of amplifier, speakers, and sealed box, to obtain low, powerful, and crisp frequencies. The controls section is complete and provides optimal regulation of the low-frequency emission in the car cabin. The Butterworth low pass filter at 12dB/Oct. with variable cut-off frequency (50-200 Hz) can be bypassed when used with an AP bit processor with pre-out output dedicated to the sub. The adjustable bass-boost control (0 ÷ 6 dB) at 45 Hz allows the user to emphasize the response on the lower side of the spectrum. The high-level speaker-in input on the multi-pole connector eases the integration with OEM audio systems while the low-level input on RCA is dedicated to the connection with after-market sources. The subwoofer automatic turn on/off function ART (Automatic Remote Turn-On) can be configured to be controlled by the source remote signal, by the voltage variation on the high-level input, or by the audio signal on both inputs. Phase control (0-180°) completes the equipment. The SSP (Sub Smart Plug) terminal block is provided with a single Plug&Play connector to be able to disconnect the box easily and safely.
Features
- Integrated 400 W RMS 0.16 D-Class amplifier featuring he-li technology
(high efficiency / low impedance) without switching power supply, for a
performance next to ideal. - Input stage DBT (Dynamic Bass Tracking) technology allows 100% use of the He-Li (High-Efficiency Low Impedance) amplifier power and to enjoy a tense and dynamic bass even at very high listening volumes.
- Butterworth low-pass filter at 12dB/Oct. with variable cutting frequency (50-300 Hz), phase control (0-180°), and adjustable bass-boost 0÷6 db @ 45Hz.
- Defeatable filter to use the sub dedicated output of a bit or AP bit processor.
- High-level audio input on multi-pin connector for maximum OEM
integration and low level on RCA for aftermarket sources. - ART turn-on function (Automatic Remote Turn-On) is selectable among Remote-in, Hi-level, and Audio signals.
- Box with ultra-low profile (6.22 in./ 158 mm) in air suspension, designed to take full advantage of the performance of the 10-inch APS 10 DL
high-impedance driver. - The SSP (Sub Smart Plug) terminal block is provided with a Plug&Play
connector to be able to disconnect the box easily and safely. - The 2S² (2 Sides / 2 Sounds) design provides the ability to select between Down-Firing positioning to increase the low-frequency extension and Up-Firing installation to obtain more punch and definition.
- Down-firing leveling feet with Velcro inserts included for a secure grip with the carpet, ensuring extreme ease of removal.
- Rounded corners allow easy placement in the trunk and act as a
reinforcement to reduce enclosure resonances. - The exclusive design of the cone, dust-cap, and basket geometry to achieve a wide linear excursion (9 mm in one direction), keeping the depth required for the assembly to a minimum.
- HRC AP remote control included.
- A sturdy metal grille is included, for the total protection of the subwoofer driver.

Perfect Work Keyboard
Color: Graphite, Style: Battery Powered, Pattern Name: Keyboard, Color: Graphite, Style: Battery Powered, Pattern Name: Keyboard
This keyboard is perfect and exactly what I needed. I wanted a higher quality wireless keyboard for work and this one is that plus some. Keys are not too loud but also not silent. The keyboard itself is thin but not too thin and has weight to it. Also love the ability to connect to other computers with the press of a button. I have a PC for work and Mac for personal use, it switches fast and easy without fail. It’s a little more of an upfront cost compared to others available but it’s worth it truly. Plus the Logi brand itself has gained my trust as all of my other tools (headset, mouse, and webcam) are all Logi and have been excellent. If you’re on the fence due to the price, just purchase and know you’ll never have to buy another keyboard again.

Great keyboard for my mother.
Color: Off White, Style: Battery Powered, Pattern Name: Keyboard, Color: Off White, Style: Battery Powered, Pattern Name: Keyboard
I wanted to move my mother away from corded keyboards so I gave her my old mouse and this keyboard. Functions well with a Linux machine although you have to pair any mice with it on a Windows or Mac computer. It's quite responsive and connects well. A valuable purchase that has survived some falls now. Very durable as long as you're not purposely trying to break it.

Good quality keyboard
Color: Graphite, Style: Battery Powered, Pattern Name: Keyboard
The Logitech Slim K950 Wireless Keyboard works great as a replacement for my old Logitech USB keyboard, but it's not perfect:
Pros: Logitech is a good brand that lasts a long time, very easy to connect via Bluetooth (ready to use in minutes) but also comes with a USB to connect manually; runs on two AAA batteries (have not had to replace yet in over a month); Slim profile with low-profile keys; no problems with the functions on the keyboard so far; it's a regular width keyboard with convenient number pad.
Cons: It is a bit pricey compared to some other Bluetooth keyboards; the volume keys are above the backspace bar and sometimes I hit those instead of backspace; the main issue for me is that it is supposed to have keys that are "quiet typing" - I don't like "clicky" keyboards and this one still clicks if I am typing fast or pressing hard. Not as much as other non-silent keyboards, but enough that I notice. That said, I tried a couple different "silent" keyboards and they really were not that much different, so maybe it's just me!
Overall this is a good keyboard and I would purchase Logitech again.

Amazing
Color: Graphite, Style: Battery Powered, Pattern Name: Keyboard
This is a very good product. I have had mine about two years now and I will buy another one should this one start to wear down.

Super quiet and slim keyboard
Color: Off White, Style: Battery Powered, Pattern Name: Keyboard
This keyboard is slim, stylish and super quiet! Very easy to set up and use right away without any problems. Seems very durable and I’m sure the battery life could be extended if I turned off the battery after using it but after a month of using it I have not had any issues. I bought the mouse that was recommended to go with it as well. Overall a great purchase.
