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.

My babies love their Benebones!
Flavor Name: REAL Bacon, Size: Large, Flavor Name: REAL Bacon, Size: Large
My one-year old pittie is 60lbs and has severe allergies to EVERYTHING, she's on medicated food and all the crazy things, and so I was trying to find something that wouldn't mess up her regimen by her ingesting it. This is PERFECT. She loves her medium sized Benebone! She carries it everywhere haha. I have three other big dogs, and got the largest one for my 110lb German Shepherd and she also loves it. I keep an eye on the edges and sand them down if I find anything sharp. These things are TOUGH. My pitbull can eat a massive bully stick in less than ten minutes, and she's barely made a dent in this thing! My GSD is a little more delicate and likes to savor and enjoy her toys, so hers isn't progressing as fast. She eats Yak Chews in around 30 minutes (and those things are like concrete!) I think these will easily last a month, possibly more, and for the price you can't beat it. The value is insane. I spend maybe 200$ a month on rawhide alternatives and bully sticks and yak chews for them, and these 14$ things last infinitely longer. BTW these things hurt like a mother trucker when you step on them, so keep an eye on where they are haha they're big and heavy!

Love these for super chewers
Flavor Name: REAL Bacon, Size: Large
I have two pit bulls and they destroy everything. These have held up very well for weeks. I use the cups for their morning yogurt and can even use hot water wand soap to wash them out. These are a great value for the money and the dogs love to carry them around in their mouths and even tug o war with them. Highly recommend.
