The18-2 SUB PRO PASSIVE SEALED SH subwoofer is so far above and beyond the competition in every aspect; refined musicality, tightness, and output levels suitable for a 18" driver. Combine this exceptional performance with an enclosure only 10,43” deep to accommodate a wider range of applications where larger enclosures just can’t fit, and this model could possibly take the home theatre market by storm.

The 18” driver is an advanced carbon rohacell composite sandwich cone. It is coupled with a neodymium motor with 4” Ultra-high-temperature voice coil. With a max SPL of 137dB @100Hz an , the dynamic expression and percussive impact that this sub can deliver puts it in a class by itself, let alone in such a shallow footprint as to almost disappear in home theatres or media rooms when compared to more traditional cube subwoofer designs.

In larger rooms where more output is needed (or just desired), ASCENDO also offers a Dual-18” version of this same enclosure design, with the two woofers stacked - The18-2 SUB PRO PASSIVE SEALED SH. The 143dB SPL @100Hz capability of this 48” high, 24” wide and only 10,43” deep defies belief until experienced.

Both models are engineered to operate perfectly in sync (in phase) with our Infrasonic subwoofers; The24, The32, The50 and The80 when there is a desire to reproduce movie content below 20Hz with the same authority, precision, and musicality. The combined results sound (and feel) like seamless and natural extensions of their individual efforts, adding to the overall addictive, immersive quality of a complete ASCENDO system.

It is ok
It is decent. Looks like it would work well. It is a little bulky. I bought this one and another one from a different seller. I returned this one due to the thickness of the arm. It was a little bulky. One thing to be mindful of there is no adjustment for the radius of the arm. Depending on how you position it your phone can be quite far away from the screen, it may not bother you, but for me I wanted them as close as possible

Strong Magnet, Great Price!
Mounted in less than 10 seconds. The magnet is super strong and holds the phone through all the bumps the road throws at it. The two thumb screws make for fast angle adjustment. The mount location puts the phone in the perfect spot for viewing without obstructing the view of the road. This phone holder is built well beyond its price point! I will be buying a second one for the wife's Tesla.

Works better than expected. Very good
Color: Black, Color: Black
Very nice fit and finish. Feels very high quality. Phone charges very quickly and doesn’t heat up as much. It charges through my heavy duty case that i thought i would have to replace as it doesn’t charge on other charges that ive tested. Very impressed.

Triple Convenience: The Ultimate 3-in-1 Magnetic iPhone Charger!
Color: Black
I recently purchased the 3-way magnetic iPhone charger, and it has completely transformed my charging routine. This product is not only incredibly convenient but also offers some fantastic features that make it stand out from the rest. First and foremost, the magnetic connection is strong and reliable, ensuring that my iPhone stays securely in place while charging. One of the coolest features is that it displays the time on the iPhone screen while charging, which makes it easy to check the time at a glance, especially during the night. Additionally, the built-in Apple Watch charger is a game-changer. I no longer have to juggle multiple cords and chargers for my devices. Now, I can charge my iPhone, Apple Watch, and AirPods all in one place. This 3-in-1 functionality has decluttered my nightstand, making my space much more organized. The sleek design of the charger also deserves a mention. It looks stylish and blends seamlessly with my decor. Overall, this 3-way magnetic iPhone charger has made my life easier and more efficient. I highly recommend it to anyone looking for a versatile and convenient charging solution!
