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.

Three froth/blend options, rechargeable, comes with container
Color: Rechargeable with Storage Box - Silver, Color: Rechargeable with Storage Box - Silver
I watch a gentleman online who always talks about how in his 40 years he didn’t know x, y, z, and ends with “ain’t no way.” He made this 3-ingredient — 4 with ice— iced coffee, and used a handheld frother, so after shopping for ingredients, I went in search of a frother. What I liked about this one is that it’s not battery operated, but instead is rechargeable. It comes with three attachment, one of which I can use for cake batter, whipping up eggs, making homemade whipped cream, and also sauces and gravy. It also has a case so I am storing it with my coffee paraphernalia. It has three settings and I used the high setting. As you can see it really froths up the ingredients. I’m very pleased with my purchase and thought about all the times I need a slurry of water and cornstarch to thicken soups and stews. I don’t know the charge life yet, but so far, so good. What you see in the cup is 2 tablespoons of sweetened condensed milk, 3 teaspoons of instant espresso, and 2 ounces of water. Then you add the ice and your creamer, half-and-half, or barista lover’s oat milk, and you’re done. Not too bad, as my grandpa used to say.

Great product
Color: Rechargeable with Storage Box - Black
It’s great! Very powerful, even on low speed. Mixes fiber, and powdered mix-ins very well as well as frothing milk. Nice sturdy little case to keep the components in. Stays charged for a long time.

Best Hand-Held Frother EVER
Color: Rechargeable with Storage Stand and Box - Black
I have had many hand-held frothers over the years; hand-held as well as counter top. None of them have really given me the froth that I want which is dense foam to the point that it almost forms "peaks" and needs to be spooned into my coffee. Additionally, the one that I always went back to (hand-held) only lasted for 3-6 months at best before breaking and sometimes it lasted only a few weeks. Additionally, it drained batteries to the point they needed to be replaced every 2-3 weeks. The Circle Joy DOES make thick, dense froth (I use very cold skim milk on the high speed), has 3 speeds and is rechargeable so no more battery issues. Once I froth the milk, I pop it in the microwave for 40 seconds or so to heat/warm it up. It also comes with an attachment for beating eggs as well as an attachment for stirring in protein powders. I don't need the egg beater and I use the low speed to mix in chocolate collagen powder. I just got this frother so reliability is yet to be proven but I figure at $20.00 even if it needs to be replaced every six months ... it is still a winner.

Works well, worth buying.
Color: Rechargeable with Storage Stand and Box - Black
Works really well. I wish the attachments were easier to get off without feeling like you are going to break them. I use a butter knife to pry it off carefully. I like having the case too, it works well if you need to travel with it.
