Flaches Design – satter Tiefbass

Der K 10S ist der Problemlöser schlechthin, wenn es um die Realisierung besonders flacher und kompakter Gehäusekonstruktionen geht. Die extrem geringe Einbautiefe dieses Woofers eröffnet völlig neue Möglichkeiten bei der Installation, ohne dafür irgendwelche akustischen Kompromisse eingehen zu müssen.

Dank seiner großen Doppelschwingspule und tiefen Resonanzfrequenz braucht sich der K 10S in puncto Bassperformance vor Woofern mit größerer Einbautiefe keineswegs zu verstecken.


Clever bis ins Detail

Die enorm verwindungssteife Sandwich-Papiermembran in Verbindung mit der hochbelastbaren Doppel-Schwingspule setzt nicht nur Verstärkerleistung lässig und ohne Kompressionseffekte in mächtigen Schalldruck um, sondern punktet klanglich genauso bei subtilen Beats.

Besonderer Clou: Das Magnetsystem verfügt über eine rückseitige Gewindebohrung und ermöglicht dadurch das Verschrauben des Woofers auch mit der Gehäuserückwand. So lassen sich Gehäuseschwingungen selbst bei geringen Wandstärken wirksam reduzieren, denn bei flachen Konstruktionen zählt mitunter jeder Millimeter Bautiefe.


Flexibler Anschluss

Die Auslegung als Doppelschwingspulen-Woofer bringt bei der Ansteuerung viel Flexibilität in Bezug auf die Wahl des Verstärkers mit sich. Egal ob 1 x 4 Ohm, 2 x 2 Ohm oder 1 x 1 Ohm Impedanz – jede Konfiguration ist bei diesem Tiefbass-Spezialisten möglich.


„All inclusive“ fürden Selbermacher

Neben dem hochwertigen Gehäuse-Anschlussterminal mit vergoldeten Schraubanschlüssen sind auch ein solides Schutzgitter sowie ein Abdeckring im Lieferumfang enthalten.

Für optimale Bass-Performance bei DIY-Einbauten findet man in unserem technischen Datenblatt Empfehlungen für geschlossene und Bassreflex-Gehäuse mit sämtlichen Parametern wie Nettovolumen, Tunnelabstimmfrequenz oder DSP-Einstellungen.

Well priced luxury feel.
Color: White, Size: Queen (Pack of 2)
This set of 2 pillows is very luxurious and comfortable to sleep on with good height but not so much as to elevate or lower the head to an uncomfortable degree. I just received them so they need time to air and expand fully but right out of the compacted box they are full and very comfortable. The fabric is very soft and there is no odor. These pillows are definitely a good price for such a luxury item. I think I will enjoy them for some time to come.

Soft...but fluffy and tall
Color: White, Size: Standard (Pack of 2)
I've only had these pillows for about a week. They are a great quality pillow. The cover is soft and seems well made. My only complaint is that they are VERY full pillows. If you're tall with broader shoulders, you'll probably love them. If you're shorter with a smaller frame you will probably feel like your head is too high and your neck at a weird angle (my problem). There seemed to be mixed reviews about softness....I would consider these a nice medium pillow. Soft filling but firm enough that your head doesn't sink to the bed. Definitely NOT a down-like pillow, so if that's what you're looking for, this is not for you.

Soft, fluffy and surprisingly comfortable
Color: White, Size: Queen (Pack of 2), Color: White, Size: Queen (Pack of 2)
I really liked these pillows. I tried to show different things in my photos because I wanted people to see the details: the design, how fluffy they are, and how full and thick they actually look. They are so full that the pillowcase even looks tight once you put it on, which I actually loved because they look luxurious and well-filled. At first glance they look very thick and high, but once you lay down they feel soft and fluffy instead of hard. They adjust comfortably and feel very cozy whether you’re sleeping, relaxing, or even reading before bed. I think they offer a really good balance because they feel supportive without being stiff. Of course, pillow preference is very personal—some people like lower pillows and others like higher ones—but for someone who likes fuller pillows that are still soft and comfortable, these are great. They are spacious, cozy, and feel like a very good purchase overall. I honestly don’t have any complaints so far. Definitely happy with them.

Great quality pillows. Very difficult wrapping.
Color: White, Size: King (Pack of 2)
The Pillows are the real deal. Very fluffy but with good support. I was surprised by the weight of the box they came in, pretty heavy so you know there’s good quality pillows inside. The one negative is that the pillows are packed in very very tight plastic because they come compressed. But the thing is, it’s really a chore to open them. You have to be careful not to cut through the plastic to the material, but the plastic is put on so incredibly tight that it’s even hard to get your finger underneath. But I found a way to open them. Near the top, insert A very flat metal ruler as far in as you could get it. Then cut through the plastic that’s above the metal ruler. That prevents a sharp tool from damaging the pillows. As you get through the plastic above the ruler, keep pushing the ruler further down into the package. Believe me, this simplifies what could be a very difficult unpacking. I am very surprised that the company that makes them does not insert the type of opener that you find on boxes you receive in the mail or even packages that you get from the grocery store where you just pull a tab and that opens the package. These are really good pillows, but you must be very careful about using a sharp object when opening the box and when trying to cut through the plastic. I am a strong man and have the tools needed, a very flat metal ruler, and a box cutter, knife, or razor. Good luck. !!
