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.

Good and can be used in many dishes.
These are pretty good mussels they have not been smoked or anything added to it but mussels, water and salt. Since they are packed like that, you can use them in a variety of dishes. I would buy them again but only when they're on sale because they are pricey.

Meaty and flavorful
I ate these straight from the tin at room temperature, sometimes sopping up the extra liquid with decent bread. I purchased these because I wanted to try an alternative to the King Oscar. I've tried a couple different kinds of mackerel over the years, and while the King Oscar has been the best I find their olive oil varieties to be a bit acrid. Not so with these Otter Kingdom fillets. Theses are actual fillets, so they are larger and meatier, and in my experience they have a looser grain than the mackerel I'm used to. They are high-quality, so I'm not detecting any bones and there's no formaldehyde-flavor, no imperfections in the cut. The oil is quite thin/watery and fairly small in volume. This isn't an issue for me, if anything I'd say it's welcome as it doesn't overpower the fish. These make a great compliment to my tinned fish rotation, which includes tuna, squid/octopus, sardines, cod liver, oysters, and sometimes sprats, salmon, and trout. The price is better than King Oscar, so I can have it more regularly without feeling like I'm being immoderate. Would recommend.

Excellent quality, but close to expiry date
I am basically repeating what another reviewer said in 2024, that the quality of these mackerel fillets is excellent except the expiry date of the case I received is only 6 months away, whereas similar products are shipping with expiry dates 4 years away. And my review comes 2 years after the one in 2024, so apparently this has not changed. Otherwise, I would definitely have given 5 stars. Regardless, I went ahead and ordered more, because that is how tasty they are and selling at a good price.

Delicious, healthy lunches!
Really tasty mackerel. I concur with other reviewers, it's a healthy slab of fish I like to drop on a bed of crushed corn chips, fork-flake it and chow down. Better than just about any other off the shelf grocery store brand.
