Overview

AT6901ST Spike Insulator

This spike-shaped stainless steel insulator makes improving the sound quality of small- and medium-sized speakers incredibly easy. Each six-piece set includes three insulators for both the left and right speakers that can be used in tandem with either the AT6902BR brass or AT6902ST stainless steel spike base insulators. Base insulators can be mixed and matched to create your ideal sound. The spike and base insulators are designed to be 18 mm (0.71”) high when used together, making it easy to adjust the insulator position.

Mix and match spike materials for improved, personalised sound

Spike insulators for enhanced separation of sound for improved clarity

These spike-shaped insulators utilize a gradually narrowing contact area to create a contact point that prevents reflected sounds and unwanted vibrations from floors and other surfaces from being transmitted. This enhances the sense of separation in sounds for improved clarity. Each insulator has a load capacity of up to 7 kg (15 lbs) for 3-point support of speakers weighing up to 21 kg (46 lbs). The spike base insulator material can also be changed as desired* to create a personalized experience, with the material in contact with the speaker having the greatest impact on the sound.

*Use with either AT6902BR or AT6902ST spike base insulators.

Rich mids and lows for a more forceful sound (when used with AT6902ST stainless steel spike base insulators)

The stainless steel increases the expressiveness of mid- and low-frequency ranges—the core ranges—for a more forceful sound.

Powerful high-frequency sounds (when used with AT6902BR brass spike base insulators)

Enjoy milder resonances and high-frequency range for a more impactful sound from the combined characteristics of both stainless steel and brass, with the sound generated by the stainless steel being slightly more prominent.

18 mm (0.71”) design ensures easy access for simple positioning

At 18 mm (0.71”) high when combined with the spike base insulator, the design makes it easy to reach under the speaker to adjust the insulator position.

The BEST sunscreen I've found
Style: SPF 50, Size: 3 Fl Oz (Pack of 1)
This is my MUST HAVE sunscreen. I've had almost every type of skin cancer (thankfully, caught early), so I NEED good sun protection, especially on my face. I have very fair skin. This product leaves a bit of a white cast, but after a short period of time, that white case is absorbed. The white cast of a mineral sunscreen might look chalky on a person with darker skin. The BEST thing about this sunscreen is I can put it on my eyelids and under my eyes, it doesn't irritate my eyes AT ALL. The other well-known sunscreen I used for a long time really made my eyes sting if a bit got into them. This is my favorite sunscreen of all time.

Solid mineral SPF with light coverage effect
Style: SPF 50, Size: 3 Fl Oz (Pack of 1)
I’m used to La Roche-Posay’s chemical sunscreens, so this was my first time trying their mineral version. The texture is actually quite nice for a mineral formula. It spreads evenly and doesn’t feel gritty or chalky. That said, it does take a bit longer to fully absorb compared to chemical SPFs. I’m already very pale, and I still notice a slight white cast. It’s not extreme, but it’s there. To be fair, most mineral sunscreens tend to do this, especially those using zinc oxide and titanium dioxide. Interestingly, on my skin it almost behaves like a very light tinted sunscreen. It slightly blurs and softens the appearance of minor blemishes and redness, which I appreciate on minimal-makeup days. It provides broad-spectrum SPF 50 protection and feels gentle on sensitive skin. I haven’t experienced irritation, pilling, or breakouts. It layers reasonably well over moisturizer but benefits from being applied in thin, well-blended layers, which adds some time to my morning routine so it's a little inconvenient. Overall, it’s a solid mineral option with good protection. Just expect a bit more blending time and a subtle cast.

Great for pregnancy (or regular use)
Style: SPF 50, Size: 4.05 Fl Oz (Pack of 1)
I searched far and wide for a safe mineral-based sunscreen for pregnancy. I settled on this one and I was not disappointed. It saved my skin from a lot of sunburn this summer! As other reviewers mentioned, it is harder to rub into the skin and can leave a whiteish tint, but that’s a small price to pay for a pregnancy-safe option.

Terrible, look like a ghost
Style: SPF 50, Size: 3 Fl Oz (Pack of 1)
I love La Roche-Posay but unfortunately, I finally came across the first product I truly hate from them. This product is a complete white mask on your face and does not settle in at all. You’ll be walking around looking like a ghost all day and it gave me a mild irritation to my eyes.

Leaves white cast, works okay under makeup.
Style: SPF 50, Size: 3 Fl Oz (Pack of 1)
First time using this sunscreen. I have very sensitive skin and thought since my skin tolerates their cleansers and moisturizers surely it should tolerate the sunscreen. So far so good. It’s very calming on my skin (maybe because of the zinc), but it leaves a noticeable white cast especially if you have dark skin. I wear mine under makeup and have a separate sunscreen from another brand on days where I don’t want to wear makeup. The white cast actually acts as a blank base and helps my foundation to lay well. A tip I learned from makeup artists years ago. Sunscreens that leave a white cast cancels out your natural color and acts as a corrector, concealer and foundation to lay better and look more like skin. Think of it like painting on a blank canvas. The texture is not lotion like and is actually quite thick. make sure to moisturize well before apply this sunscreen. I’ll write an update if I notice any negative issues, but so far I’m content with it because of the purpose I'm using it for.
