Designed with an extended pole piece and an incredible four inches of peak-to-peak excursion, the X v.4 is engineered for ultra-deep bass and high power handling. Engineered to set a new standard in the low-frequency/small-ported-box subwoofer category, the X Series can also work in up to a 50% larger enclosure if you desire even more low-end extension.

The X v.4 series differentiates itself with its incredibly linear suspension, ensuring the lowest level of bass extension in a small enclosure while maintaining extremely low levels of distortion. Notably, the v.2 series features a much larger motor structure (220mm vs. 190mm on the v.1 series), improved motor ventilation, and an all-new Mega-Roll v.2 surround, providing a more linear and rugged update to the world-famous Mega-Roll v.1 surround design.

A Must Have For Your Summer Beach Bag!!
Style: SPF 30, Size: 1 Fl Oz (Pack of 1)
I recently purchased the Sun Bum Original SPF 30 Sunscreen Face Stick, and I am thrilled with its performance. This sunscreen stick has become an essential part of my beach routine, and I couldn't be happier with the results. One of the standout features of this product is its convenience. The stick format makes it incredibly easy to apply the sunscreen evenly to my face. I love how smoothly it glides on, leaving no white residue or greasy feeling behind. It's compact and fits perfectly in my bag, so I can carry it with me wherever I go. The level of sun protection provided by this sunscreen is fantastic. With SPF 30, I feel confident that my skin is well shielded from harmful UV rays. Whether I'm spending a day at the beach or just running errands around town, I know that my face is protected from the sun's damaging effects. Another great aspect of this sunscreen is its formula. It's lightweight and non-greasy, which is perfect for my combination skin. Unlike some other sunscreens I've tried, this one doesn't clog my pores or cause breakouts. It feels comfortable on my skin throughout the day and doesn't interfere with my makeup application. The Sun Bum Original SPF 30 Sunscreen Face Stick also has a pleasant scent that reminds me of summer. It's not overpowering or artificial, which is a big plus for me. I appreciate the attention to detail in creating a sunscreen that not only performs well but also provides a pleasant user experience. Overall, I highly recommend the Sun Bum Original SPF 30 Sunscreen Face Stick to anyone in need of a reliable and convenient sunscreen for their face. It offers excellent sun protection, has a lightweight and non-greasy formula, and is incredibly easy to apply. With this product, I can enjoy my time in the sun without worrying about my skin's well-being.

Beach bag staple
Style: SPF 30, Size: 8 Fl Oz (Pack of 1)
I’ve used Sun Bum for years and always come back to it. SPF 30 is perfect for everyday beach and pool days, and it gives solid protection without feeling heavy. It goes on smooth, doesn’t feel greasy, and doesn’t leave me looking ghostly. The smell is classic Sun Bum summer vibes and not overpowering. I’ve worn this in full sun and never had issues with burning when I reapply. Easy to rub in and comfortable to wear all day. Would absolutely repurchase.

The smell of summer
Style: SPF 30, Size: 8 Fl Oz (Pack of 1)
Love this lotion and its smell! Offers both protection and hydration and is my go to sunscreen for tanning / laying around. It'd definitely not my sunscreen for running / workouts / etc. because it doesn't feel like it hold up great to sweat.

Highly recommend for face sunscreen care!
Style: SPF 30, Size: 1 Fl Oz (Pack of 1)
A great choice for waterside sun protection. Rolls on smoothly and protects your skin from sun. As someone with sensitive facial skin I was relieved to find no issues after applying for a week straight. I plan to keep this product regularly on hand.

Expensive but good
Style: SPF 30, Size: 8 Fl Oz (Pack of 1)
It's not the best for your skin but it works and doesn't leave white cast and is nice and easy to apply to the skin. It smells good too but youll run out quick and have to buy more. Lasts like a month or something if you are apply to face, neck, arms, legs.
