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.

Looks nice but not comfortable
Size: 9.5, Color: Black
Look nice, fit well, but there is no cushion on the sole so feet hurt after wearing for even a short time.

Nice shoes
Size: 11, Color: Black
bought for my husband to wear to a funeral. Since he would only be wearing them for a day as we don't dress up ever he didn't want to spend allot. The shoes themselves look more expensive than they were and he said that they were comfortable enough. Not sure how well they will last with daily wear. the services had allot of dirt and the shoes were easy to wipe clean with a damp towel

From a Long Time Hard Sole Dress Shoe Wearer, These are a Must Have!
Size: 12, Color: Blue
I have been wearing hard sole dress shoes for decades and with the full COVID shift to dressing super casual in a professional work environment, I was in the market for some more casual let dressy shoes that were a heck of a lot more comfortable and flexible than my hard soles so I thought I would give this brand and style a try. Oh man, I'm in love. These give you that dressier look yet you can totally dress them down with jeans or cordouroys, so versatile. As I did with my hard soles, I inserted one of my Nike Air in soles and man, these are so comfortable I bought navy and brown! I usually wear these with thin dress socks and they go perfectly with any type of suit set, a no brainer purchase here. I'm a 12 and bought a 12, perfect fit, not to skinny, not to wide, just right. Bottom sole grip is impressive, never felt unstable, solid rubber sole here. I decided to lace them up so there are not tying and the tongue does slip down sometimes so with this feature, best to use a metal shoe horn, then it's super easy to slide them on, they seem to take a beating and remain clean too, I've definitely scuffed them up against many things and still no damage, it's crazy, must have a great finish. NOTE TO Note to MANUFACTURER/SELLER - You need to make a version in GRAY in this specific style and I will buy them instantly, and I assure you they will be incredibly popular! Really not sure why there isn't more colors in these like gray, shades of gray, maybe red, lighter blue and maybe some with different tones in standard colors. Casual dress shoe wearers are looking for new and exciting bold colors so this is the perfect shoe type to deliver on that.
