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.

Transformative for Dry, Cracked Heels!
Color: Original Grey
I recently purchased Dr. Frederick's Original Moisturizing Heel Socks, and they have truly transformed the condition of my feet! I can’t recommend them highly enough. Effective Moisturization: These socks are infused with moisturizing agents that work wonders. After just a few uses, I noticed a significant reduction in dryness and cracking on my heels. My feet feel softer and smoother, and I love that I can wake up to beautifully moisturized skin. Comfortable Fit: The socks are incredibly comfortable to wear, with a snug yet gentle fit. I appreciate that they don’t feel restrictive, allowing me to walk around my home while wearing them without any discomfort. They are also lightweight, making them easy to slip on before bed. User-Friendly: They are super easy to use—just wear them overnight, and let the socks do their magic. I love the simplicity of incorporating them into my nighttime routine. Durable Quality: The quality of the socks is impressive. They wash well and have maintained their shape and effectiveness after multiple uses. I feel confident that they will last a long time. Final Thoughts: If you're struggling with dry, cracked heels, I highly recommend Dr. Frederick's Original Moisturizing Heel Socks. They are a fantastic investment in foot care and have made a noticeable difference in the health of my skin. These socks have become a must-have in my self-care routine!

These worked for me!
Color: Original Grey
They worked great. I bought these for cracked sore heels. It took 2-3 weeks but my heels no longer hurt and the cracks have closed and look more like an indention than a crack now. They feel so much better, but I'll probably wear them another week just to be sure they stay healed. They look and feel like regular socks from the outside but only cover the heel with the toe open. Not think but not thick, again like regular socks. They would probably be slippery on a smooth surface the same as socks. The inside feels like rubber or something smooth at the heel. I have washed them once each pair and accidentally dried one pair in the dryer. They still seem to feel the same so I think they're fine. They're pretty inexpensive and had different colors and sizes.

Truly Helped My Cracked Heels
Color: Original Grey
I didn't include a photo cause they look exactly like their advertisement photo. I so liked the silicon-type heel lining as it kept the heel-repair cream on my heel and did not get soaked up by the sock. But, it is so, so slippery when walking around in them! Take care to be mindful when you set each foot down as the lotion can slide your heel across the sock quite a bit. If these socks were for an elderly person, I would have them only sit while using the sock - no walking around for fear of falling. I have larger ankles and found that having both the top and the bottom hems/elastic, etc. the same size to be quite troublesome and was not a nice feeling or fit on my upper hem that hit my ankle. Don't get me wrong, I am so glad that I got them and I continue to use them and they are helping my horribly-cracked heels greatly, but I find that I have to keep moving the top hem up and down so that it doesn't stay in one position as it cuts in to my ankle. My feedback and advice might be to please make the upper hem somewhat larger than the one that is on the bottom and goes over my actual foot. They really should not be the same circumference...or else make different sizes - S, M, L, etc. That's really my only complaint or "con" to ordering these. I think they are a great concept and I like the fact that I can throw them in the washer and dryer.
