Authentic seismic infra bass

The SMSG50 infrasub touches unknown territory and dimensions when it comes to reproducing the deepest frequencies. At the same time manifests itself as the definitive proof of how important the infrasonic subwoofer is in serious home theatre arrangements. It challenges the known limits and lays the cornerstone for a cinematic experience of superlatives. Equipped with a gigantic custom-built 127 cm/50” driver powered by DSP-controlled 6000 watts using the AIA Speaker Management technology, the SMSG50 is hands down the most powerful cinema subwoofer in the world. The speed, definition and authority paired with clarity to differentiate frequencies in the single digit range are mind blowing.

Due to its ultra-low resonance frequency and its sealed braced enclosure concept, this mega subwoofer delivers an extremely fast impulse response and class leading low group delay compared to any subwoofer out in the market. It’s absolutely unique and fascinating with which ease the SMSG50 is able to reproduce the lowest frequencies literally down to 1 Hz. With each maximum stroke, the SMSG50 moves as much air as forty standard 18" subwoofers. This incredibly massive bass power hardly ever reaches the limit. The SMSG50 renders with high-resolution, finely structured and explosively fast. If required, with peak levels up to 140 dB and amazing 105 dB LFE reference level of sound pressure at 5 Hz in larger rooms substantiate its unique position on the market.

The SMSG50 redefines efficiency and sensitivity in low bass reproduction. With its extremely high speed and low frequency resolution, it enriches all state-of-the-art home theatres and shifts their low-frequency performance to an unprecedented new level. It is the perfect upgrade option for existing world class home theatres.

The Ultimate Solution for Power Chewers!
Flavor Name: Beef, Size: Medium
I have a Pitbull mix who can usually destroy "tough" toys in minutes, but the Bam-Bones Plus is a total game-changer. The bamboo and nylon blend is incredibly dense; it satisfies that natural urge to chew without splintering like real wood or falling apart like rubber. It wears down slowly and safely, giving my dog weeks of use rather than minutes. ​Smart, Functional Design ​The T-bone shape is brilliant because of the "paw-grip" base—it makes it so easy for my dog to hold it steady while she works on it. I’ve also noticed her teeth looking much cleaner since we started using this, as the raised textures act like a natural toothbrush. Plus, the infused beef scent keeps her interested much longer than a plain nylon bone ever could. ​Final Verdict ​This is a must-have for any owner of a large or aggressive chewer. It’s safe, long-lasting, and provides excellent mental stimulation.

Fantastic Durable Chew Toy That My Dog Loves!
Flavor Name: Beef, Size: Medium
Absolutely thrilled with this dog chew toy! It’s extremely tough and durable — perfect for aggressive chewers and keeps my pup entertained for a long time. The bamboo fiber and nylon design feels sturdy yet gentle on the teeth, and it even helps with dental hygiene by massaging gums while he chews. My dog goes crazy for this bone and it lasts way longer than other chew toys we’ve tried. Great quality and great value — highly recommend for any dog

Great stimulation for active chewers!
Flavor Name: Peanut Butter, Size: Large, Flavor Name: Peanut Butter, Size: Large
"Long lasting chews" never make it past 5 minutes in mouth of my Golden Retriever, but this one will! He immediately started chewing on it and barely made a dent. Love that this product is safe, clean, and enjoyable for my boy. Highly recommend!

100% Puppy-Approved
Flavor Name: Beef, Size: Small
My little fur baby absolutely LOVES this!! ❤️ He immediately got the zoomies when I gave it to him. 🤣 It's his new favorite chew toy and keeps him occupied for long spans of time while inside or outside of his crate. Very durable, smells pleasant, and is the perfect size for my small puppy (he is currently 10 lbs and I got him the small one). Previous chew toys that I purchased were too large/heavy for him to pick up, but this one is lightweight and perfect! I highly recommend! 🙌🏾

Not destuctable
Flavor Name: Peanut Butter, Size: Medium
This is the first toy that none of my dogs have destroyed. It's still going strong and they love carrying it around and gnawing on it every day. The material is durable and the product is the perfect size. I will buy more soon.
