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.

Smooth edges better than twisting
Works a lot better than the crank style and the counter top electric and you can use the lid to reseal the can if you don't use the whole thing.

Worked for only 4 months. Now produces metal shards. Dangerous
Pros: Can be used with one hand. I bought this to have after surgery that left me without use of one arm for a few months. The light blinks when you need to charge it. Only needs a 2-3 min charge for enough juice to open a can. Cons: IT QUIT CUTTING CORRECTLY AFTER 4 MONTHS. I now have to use both hands to hold it in place to get it to latch on to the can. It also requires a few rotations around the top to cut through the seal, resulting in METAL SHARDS! The metal shards are super sharp and almost invisible. I stabbed myself with one enough to draw blood. This is dangerous as the metal could fall into the food when pouring from the can.

Can opener
This product does not work well! It actually doesn't work at all!! Will not cut thru can lids at all. Very disappointing to say the least. I purchased to make things easier only to be left not being able to open dinner 😕. Would not recommend to anyone!!!

Can opener
It doesn't shut off by itself when done and doesn't shut off when I push the button, so after a while it will shut off but when it wants too after you take it off the can ,like 30 seconds. But I do like the way it cuts, a clean cut and lid removal nice.

So simple to use, I'm amazed
Color: Black
Wonderfully helpful. Description is accurate, shipping was quick. I saw a few poor comments, but I have none so far! The can opener has opened cans of several sizes, from tomato paste to large cans of tomatoes; soup cans to strangely shaped. It's opened 30 or so already without loss of power. It's a little noisy, but about equal to that of a stand up opener. It fits in my drawer, which is less deep than most kitchen drawers. Most of all, it's beyond easy to use for arthritic hands. The ONLY CHALLENGE I have is that it sometimes fails to stop when it should. MANUFACTURER: if you read this and have advice, please share. At this point, I'd say this is a great value for the money.
