The EAW SB528zR is a high-output, 1400W passive subwoofer designed to deliver deep, impactful bass for the most demanding professional applications. As part of EAW's prestigious SB series, the SB528zR features dual 18-inch drivers housed in a vented, optimally tuned enclosure, delivering low-frequency extension and high output typically associated with much larger subwoofers. This versatile, large-format subwoofer is ideal for both portable and permanent installations, providing the deep, "fatter" bass sound desired in applications such as concert touring, large houses of worship, arenas, f/x reinforcement, cinemas, large auditoriums, and large dance clubs. Its compact size relative to its power output makes it suitable for installations where space is limited but bass impact is critical.

The SB528zR is engineered for high-performance, with two 18-inch drivers that handle up to 1000W of continuous power (AES) each. The direct radiating design ensures that the subwoofer produces clean, powerful bass without distortion. Its operating frequency range of 27 Hz to 147 Hz ensures extended low-end reproduction that complements a wide variety of full-range loudspeakers. The subwoofer achieves impressive SPL levels, including an average SPL of 129 dB (whole space) and 135 dB (peak, whole space), and 135 dB (average) and 141 dB (peak) in half space. This level of output makes it well-suited for large-scale applications, providing plenty of punch for bass-heavy events or sound installations that require high levels of dynamic impact.

Designed with flexibility in mind, the SB528zR can be configured for either single-amp or dual-amp operation, allowing it to be used in a variety of system setups. The nominal impedance is 4 ohms per driver, with a minimum of 3.9 ohms at 131 Hz, ensuring compatibility with most professional amplifiers. For optimized low-frequency performance, EAW recommends using their MX Series processors for proper crossover and equalization. The recommended high-pass filter at 25 Hz with a 12 dB/octave Butterworth slope ensures that the subwoofer operates within its ideal frequency range while protecting the drivers from unwanted frequencies. The subwoofer is designed to operate reliably even in the most challenging conditions, handling up to 1400W of power and delivering consistent performance for the long term.

The SB528zR's robust construction includes an enclosure made of Baltic birch plywood, which enhances both durability and resonance control, ensuring that the subwoofer performs optimally over time. The wear-resistant textured black paint finish provides a sleek and professional appearance, while the powder-coated perforated steel grille protects the drivers from damage while maintaining optimal sound dispersion. With dimensions of 30.19 x 50.69 x 24.56 inches and a weight of 215 lbs, the SB528zR is a substantial subwoofer that delivers the bass performance needed in large venues and demanding environments. Its 360-degree coverage ensures that bass is evenly distributed throughout the space, making it ideal for large venues or events where consistent bass reproduction is required across the entire listening area.

Very soft and comfortable
Color: Black, Size: 1 inch
I really love this yoga mat. It has the perfect balance of comfort and support, so it feels soft enough on my joints but still stable for workouts and stretching. It doesn’t slide around on the floor, which makes me feel more secure during poses. The grip is really good even when I start to sweat, and it’s easy to roll up and store when I’m done. I also like that it’s thick enough to cushion my knees and back. Overall, it makes my workouts more comfortable and enjoyable, and I actually look forward to using it.

As Advertised.
Color: Boysenberry, Size: 1 inch
The boysenberry color is pretty. The Retrospec mat is odor-free, 7/8” thick (so close enough), dense, and non-slip on my wood floor. I wanted the density to cushion pressure points whilst performing various core exercises and general stretching on the floor. It works well for my purpose. I agree with other commenters, the 1” thick mat is too unstable for yoga. That said, the slight instability makes this mat useful for developing balance and core stability by balancing on uneven surfaces, similar to the benefits of walking on grass or trails. The mat is easily nicked by long nails (human and animal) rocks, sticks etc. so pay attention to where you set it up; however not a deal-breaker for my use. I originally looked at the BalanceFrom GoCloud mat because it is the mat that appears in several online reviews with a link to Amazon. However, once on Amazon, I noticed remarkable similarities between the GoCloud and Retrospec reviews. I suspect both mats are identical just with a different brand name and sold by different companies. I ultimately went with the Retrospec mat because the Retrospec is sold and shipped by Amazon so the benefits and protections of “Amazon Prime”, including free returns, apply. The GoCloud mat could be returned however according to the fine print, if the return wasn’t due to Seller’s error the return might be subject to a restocking fee. One of the most objectionable review comments common to both brands had to do with the mat having a terrible, lingering odor. I was willing to take a chance and order it, but would have returned it if it had a bad odor. I did not want to pay a restocking fee so went with the Retrospec mat sold and shipped by Amazon. One exception is Amazon Prime offers the GoCloud in black only. I didn’t want black because I expect to occasionally use it outside in the Florida sun and it will get really hot.

Quality weights for all fitness levels
Style: 32lb Set, Style: 32lb Set
Why did you pick this product vs others?: Good quality and the stand is very sturdy.  The stand was super easy to put together and it’s held up incredibly well. I’ve used these weights almost every day for the last couple months and they aren’t showing any signs of wear. They are definitely well made were exactly what I was expecting. The stand has been knocked over and dropped many times and it still works and looks as good as the day I put it together. They are very comfortable to hold during workouts and they aren’t slippery when your hands get sweaty. I would definitely recommend these!
