The12 SUB PRO PASSIVE SEALED SH with its sealed cabinet concept offers a rock-solid bass sound from the smallest of dimensions, easily integrable in restricted installation situations. With its shallow depth of 210 mm (8.27”) and exceptional 12” woofer, it can deliver the kind of tight, punchy bass and impressive dynamics that many would like from their modest home theaters or media rooms, all while tucked away in out-of-the-way locations.

The12 SUB PRO PASSIVE SEALED SH shares the same core design advantages the entire range of ASCENDO subwoofers feature - extremely low distortion to reproduce the finest details with the highest dynamic range to meet the content transients without compression, but perhaps more importantly, a linear response from bottom to top to allow for exceptional integration with the main and surround channels.

GREAT product!
I have had mechanical wine openers before and found them to be more annoying and more time consuming than just using a traditional corkscrew. NOT the case w/this one. So.... 1. display: the charger station is small enough in size that it would fit in most any location w/o taking up too much space. For those that do not like clutter or one more "gadget" to sit out, this is a good size. The charging station has a little holder for the foil cutter as well which is great and keeps all parts together so no one has to search drawers when ready to open the bottle. There is a blue light that glows while being charged and is very pleasant to look actually and is a nice touch. so it actually looks really good sitting on top of the wine rack. Mine happens to be right next to an electrical plug on the wall so does not reveal the hanging cords or wires. 2. function: works great so far and have opened quite a few bottles. very easy to use. would suggest holding the bottle by the fatter part toward the middle and then using the other hand to work the corkscrew. does not work well if the bottle sits on the counter unless you have a good solid grip on the base. Its actually easier to just pick up the bottle and do it that way. of course that's after using the foil cutter which gives a perfect cut and removal each and every time. 3. battery life: i think the product says it can be used for 30 bottle openings during a single charge. that is quite more wine that most people would be going through in an evening so i don't think anyone would have an issue w/keeping a charge. I use it and then put directly back on the charging station as i do my mechanical salt and pepper grinders. that way, its always on the cradle and charging. as mentioned there is a blue light that glows in the actual item while its charging and i like the way it looks so would have no reason to keep it off the charger anyway. this also makes a GREAT gift especially a house warming gift to anyone who drinks wine or entertains

Great but had a problem
It’s great except you have to finagle the darn thing for it to charge. Sometimes I have to use something to get it to lean just right so it charges. Otherwise it’s spectacular and easy to use! Love the foil cutter tbh, that works like a gem!
