Alumine Two.Five

Simply iconic.

The all-new Alumine Two.Five is the exciting latest addition to the Alumine range. It is the first floorstander in the line-up and slots between the bookshelf Alumine Two and the floorstanding Alumine Three.

The iconic Alumine Two changed speaker design and redefined what was possible from a bookshelf speaker. It achieved this by combining elements that have served as the basis for every Stenheim speaker since: aluminium cabinets, highly efficient drivers and sophisticated crossovers that are designed to be as unobtrusive as possible. The Alumine Two achieves its astonishing musicality partly by virtue of being a two-way design, the crossover only having to deal with two drivers, the tweeter and the bass. In audio, simplicity is the holy grail but extremely difficult to achieve.

Now the Alumine Two.Five takes these same design concepts and applies them to a floorstanding cabinet for greater internal volume and bass extension. The design is still a two-way, eschewing the compromises that may result from a more complicated crossover required to handle multiple different drivers. The purity and simplicity that created the success of the Alumine Two is maintained, but the double bass drivers ensure room-filling sound in larger spaces whilst giving greater extension in the low frequencies.

The easily driven Alumine Two.Five is suitable for a wide range of high-quality amplification and is the ideal partner for even modestly powered systems, such as tube amps, to deliver enthralling music with typical Stenheim clarity, detail and liveliness. It is hand-assembled in our manufacture in Switzerland with quintessential Swiss attention to detail and quality and is designed to perform for decades.

The classically elegant, slim cabinet makes it a beautiful addition to any listening space or living room, complementing any décor, without seeking to be the centre of attention. That is the role performed by the sublime music it produces the moment you hit play.

The Alumine Two.Five is simply beautiful, however you look at it or listen to it.

“ALUMINE TWO.FIVE: MIRACULOUS BALANCE” - HAUTE FIDÉLITÉ MAGAZINE (French)

From Sol Gabetta playing Mendelssohn to Talk Talk in 'The Colour of Spring', the Two.Fives demonstrate their obvious talent for extracting the best from every musical genre. (…) The degree of perfection in all areas of musical performance reaches dizzying heights, and you'll need sources and amplification to match, but they can content themselves with around thirty excellent watts to give their best.”

For me, it is gorgeously honest, divinely minimalist, purpose-forward design that is perfectly proportioned for most rooms. I love the look and scale of them in my space. (…) Incredible performance from a modest-sized floor-standing speaker.”

Owners’ Testimonials

"These speakers actually look quite 'regular,' but they’re really special. They bring together qualities I previously thought were incompatible extremes. They’re small but sound really big — balanced yet outspoken, lively yet quiet. The aluminum makes them feel cold to the touch, but they sound incredibly warm. The sound is light-hearted but also very 'dense' in terms of detail, with sparkling highs that are never harsh."

Rik S., 2025

Surprisingly amazing chair!
Color: Pink, Color: Pink
tl;dr: If you need a chair that has the features of this one, then this one is a winner! Hits above its weight class for sure. My wife is 5’. She’s small. For whatever reason she ended up with a chair made for big people, like 6+ feet and up to 500lbs type of a chair. She’d often even sleep on it and chill on it. The chair was big enough to fit 2 of her to be honest. It was an expensive chair that I won at some raffle and didn’t like myself. Over the years it ripped (got a cover for it) and even started to get lopsided (from the sleeping) and finally a spring broke (hence the pillow on it in the pictures) She obviously lives pink. I also wanted to get a chair where she could work and not end ip asleep on. Not like we have a couch or a bed for that 😂. This chair is very obviously smaller than her previous chair, it’s also significantly cheaper in price and build, it’s also not as durable feeling or stable, and it’s just not as padded. Yet somehow it’s an amazing chair that we both like better than her previous chair??? Like it’s crazy that this chair somehow works better in so many ways. Her desk is modified to be shorter than normal desks (again, she small lol) and her previous chair was just too big. The wheels are also like SUPER smooth, like you can run a chair race easily with it. It rolls over her rug and tucks into her desk (which is in our bedroom) easily. The amount of space this has save us when the chair isn’t being used is a lot. Previous chair was much bigger and didn’t tuck in at all. The color is nice and the padding is plenty for a small and much lighter than 500lbs woman. I’m 6 feet and 200 lbs and the chair is nice for me as well. My chair is bigger and more secure in the backing, which is similar to this one. The lowest tension setting on my chair is still too high for her to lean back on my chair. This chair has a lower tension minimum and she can easily lean back freely, as well as keep enough tension to work without sagging. This chair is surprisingly outstanding! I’m sure my wife will destroy it quicker than the last one, but it’s so cheap that even if it only lasts 1-3 years, I’ll happily buy it ones or twice more 🤷🏽‍♀️. Maybe by then they’ll invent a comfortable titanium chair that’s affordable that she won’t destroy 😂.

Mid.
Color: Light Purple
The chair is fine, and reasonably easy to put together. However, I've been using it for a little over a year and a half, and it's already falling apart. Random parts of it have fallen off, which is fine because it was still functional. But now the most frustrating part is that the wheels continue to pop off, and while the first attempts to pop them back on worked, they will not stay on now. This is obviously greatly impacting the stability, and I will need to purchase a replacement soon. For this price and lack of long-term durability, I would not buy again.

Alexa messed me up, but the company of the chair made it right!
Color: Light Purple, Color: Light Purple
I wanted something small with arms that moved out of the way when I wanted to slide my chair all the way into my desk for more space. This fit the bill. I loved the color blue and I had that in my cart for a bit. One day Alexa mentioned that an item that was in my cart was on sale. It was the chair. I let it be ordered. When it came it didn't exactly look blue to me. But I kept putting it together thinking maybe it was the lighting in the room I was assembling it in. I brought it to my craft room and lo and behold it is light purple. I looked at my order and sure enough it said light purple. Boo! I looked in my saved cart and the chair was gone. So I accepted it for an error. The next day I checked to see if I could return it. Thought I could, till I read that I would have to pay to return it. So I wrote the seller to tell them to ignore the return. And that was that. Till a couple days later I get an email from the seller asking if I would like a full refund or a replacement at no cost. I was like heck yeah send me the blue one. I was thrilled and I wanted to thank the seller for doing this without the return of the other chair. But I could not find a place to do that now. So here is where I will thank you. Thank you so much for doing this for me. You guys are AWESOME!. I love the chair and I love the blue color. I find it very comfortable, lite, easy to adjust, the size works great for me, and for the price the quality fits my needs. I do hope it lasts me for quite some time. Thanks again!

Awesome chair definitely recommend
Color: Blue, Color: Blue
It was amazing the color was spot on and it was very very easy to put together and the size is amazing for my 11 year old daughter maybe not for an older person it doesn’t recline as much as it says so if you want a reclining chair maybe I don’t recommend this chair but the quality is amazing and the adjustment capability is incredible the noise level is at 0 it is an amazing chair we just got it so I don’t know so much about the dupability so if you want this chair for a child or a tween maybe even a teen easy to put together beautiful blue color this is the chair for you.

Easy instructions, comfortable cushions
Color: Pink
I just put it together and I love it!!! It's so comfortable and it was easy to put together. You can rock it back and forth which helps your back. The seat is very wide and the cushion is thick. Pink is my favorite color, and this chair satisfies my pink obsession.
