HELIX PURE R-series: Flawless sound, pure excellence

HELIX PURE transcends beyond mere music. It's an audiovisual journey, dedicated to uncompromising sound quality and uniqueness, designed for discerning audiophiles and individualists who refuse to make compromises in their daily life. The PURE R-Series represents the pinnacle of our PURE speakers, combining their essential features to perfection: uncompromising sound quality, high-quality materials and unparalleled aesthetics.

Highest Quality and elegant design

Our premium speaker systems are the result of years of development and an unwavering commitment to highest quality standards. By utilizing state-of-the-art components, they deliver an unparalleled sound reproduction and a dynamic musical experience that is second to none. Here, quality is not only audible but tangible as well. The timeless, elegant design discreetly and harmoniously blends with the interior, providing aesthetic pleasure without ever being obtrusive. Through the use of innovative technologies, the achievement of sonic precision can be felt in every note, while also allowing incredible power handling that doesn't even compromise at demanding volume levels.

Absolute high-frequency brilliance

The HELIX PURE R-series premium tweeter is an example of absolute excellence within the PURE speaker lineup. It distinguishes itself with the lowest possible manufacturing tolerances and exclusive use of top-tier materials, such as the coated silk dome. This component leads to the faithful rendition of even the finest details, ensuring a smooth and natural sound reproduction for an unmatched high-frequency experience. Furthermore, its smart and compact design offers diverse mounting options for a universal installation. The anodized aluminum flush mount housing with the solid mounting ring allows a concealed installation, while the included grilles, available in two exclusive designs, provide both protection and aesthetic options.

A sound experience that you can hear and feel

The HELIX PURE R-series premium woofer delivers unparalleled sound quality that you can hear but also feel. The stiff Mica-Paper composite cone ensures not only a punchy kickbass but also delivers a balanced midrange reproduction that brings your music to life. To achieve optimal impulse response, it utilizes an exceptionally powerful magnet system while the rigid aluminum diecast basket with streamlined, low-turbulence design guarantees ideal impulse fidelity. Furthermore, additional ventilation holes in the basket enhance coil cooling and enable impressive power handling. Always included: HELIX grilles for the ideal protection of the cones.

Maximum flexibility – Flex-Crossover

The separatable Flex-crossover is not only a visual highlight but also provides a wide range of connection possibilities due to its technical refinements, making it perfectly-suited for installation in vehicles with separate mounting locations for tweeters and woofers. It offers a 3-stage tweeter level adjustment for optimized treble adaptation to the respective mounting position, while featuring a 12 dB slope for tweeters and woofers that has gone through extensive fine-tuning.

Delicate and pretty but does the job
Color: Light Coral, Size: 40DDD
This is a new brand of bra for me and I got it because it was recommended. Today I'm wearing it and have a few thoughts: 1) The straps are comfortable. In fact, the whole thing is comfortable. It doesn't look like it would be comfortable at all, but it's pretty nice. 2) I'm not so sure about the sturdiness. When putting this on this morning, the mesh actually ripped a little bit as I was positioning it around my torso after buckling the back together. This is how I put bras on: Turn it upside down and have the snaps facing the front, snap the snaps, then rotate it around your torso until it's positioned correctly, then flip it rightside up over your breasts. Is there some other way? I'm super afraid of ripping the delicate material now. 3) Despite how delicate the material is, it does have some give once on and holds my breasts well. 4) The fit is good. I'm normally a 40DDD. If I go up a cup size, then the underwire digs into my skin, so I want to avoid that. These seem a bit snug so as I wear it today, I'm going to watch for "spillage" where breasts start bunching up at the top. I know, that sounds so gross, but larger breasted ladies know what I mean! To answer some questions: Yes, it has adjustable straps. Are there bras that don't have adjustable straps that aren't sports bras? Yes, it is machine washable, though this is one of the first bras where I think I might actually need to use a delicates bag because the lace is just so delicate. It's very pretty, holds well, minimizes well, is pretty comfortable, but just a lot more delicate than I'm used to.

Great affordable bra
Color: Balsam Blue, Size: 38I
Best bra I have purchased! I wear a 38 I and this is without a doubt the comfiest bra I own. No side boob or uniboob! The fit is perfect and there is no spillage on the tops or sides and I'm not having to constantly adjust myself. I didn't think it was possible to find cute, supportive bra for under $40 but here we are. They also have great support for when I'm at the gym. I do tend to still put a looser fitting sports bra over the HSIA bra when I'm working out for my own comfort, but it's not really necessary and I would most likely be fine during my workout without the extra layer.

Cute but could be better
Color: Dark Pink, Size: 38DD
This bra definitely looks really good and has a sexy style to it. It does a decent job overall, especially for the price, but after trying two different bras from the same brand, I honestly liked the more expensive one much better. The lace on this one is pretty, but it shows through thin shirts and tighter materials. The underwire also started digging into my skin after wearing it for a bit, and the lace caused some irritation. The fit wasn’t bad, but the pricier version was noticeably more comfortable and fit better overall. For $16, this bra is still decent and looks nice, but if you’re deciding between the two, I’d recommend spending a little extra money on the more expensive one for the added comfort and better fit.

Best bra ever 💯
Color: Dark Pink, Size: 38DDD
I have seen these bras hyped everywhere especially tiktok, so I was expecting to be somewhat disappointed. Instead i am shocked by how much I love it and am immediately looking to buy more of them!! This is the most comfortable bra I have ever worn. I am a 38DDD, and it actually does appear to minimize and lift my chest in shirts while being so much more comfortable than any other bra. My back pain is gone???? Its affordable??? 100000000/10. Buy it 😭😭

Good fit, but wire isn’t good for super lg breast
Color: Purple, Size: 36I
While I love the fit of these bras I’ve order almost one in every color, I have to say the wire does break a little easily they always snap right under my under arm now ik I have very large breast I’m between a I and J cup. These are a little tight but you can still adjust them I still love them despite the wire snapping. I’d say they last longer for small breast like my sister I accidentally ordered the wrong cup size and it fit her now she’s hooked on this brand and has an equal amount of colors😂 it’s easy to wash and I wouldn’t say it’s soft because it’s mesh I don’t think mesh is that soft like silk or anything but it’s definitely smooth and see through so my bf and I love that part whenever I wanna get spicy and send a pic during the day.
