KEF KC62

Love this subwoofer! Awesome performance up to relatively loud levels. Super musical, integrates seamlessly with a variety of equipment. Very compact, beautifully constructed, sonically faithful. Recommended without reservations for small to mid-sized rooms for music. Not recommended for people who prefer disproportionately loud thumping for home theater or gaming. Fine for loud music or movies, with the caveat that the system dials back lower frequency signals at high volumes to prevent damage and to ensure quality reproduction.

As a long-time fan of compact subwoofers, I've owned several, including the SVS Micro 3000, Q Acoustics, and a classic Velodyne HGS-10. Initially, I was skeptical about the KEF subwoofer due to its small drivers, being accustomed to 8-inch or 10-inch units. The absence of advanced features like SVS's active equalization also gave me pause. However, all my doubts vanished after experiencing the KEF. I am now a true KEF believer! I was genuinely shocked by how seamlessly the bass integrates. It's incredibly difficult to discern that a subwoofer is even present, a stark contrast to most subs that often introduce noticeable frequency bumps or dips. With the KEF subwoofer engaged, my LS50s gained several octaves of seamless extension, significantly enhancing the depth and width of the soundstage. What's even more impressive is that this small subwoofer reaches notably lower frequencies than my 8-inch driver SVS 3000. Another astonishing aspect is the near-zero cabinet vibration. I expected a small sub to "hop around," but this unit seems to defy physics. I cannot overstate how perfectly this subwoofer complements the LS50s. Furthermore, its compact size and the fact that it houses 6-inch drivers make it an instant conversation starter among friends. I'm unsure how KEF achieved this, but the result is fantastic! I wholeheartedly recommend this subwoofer to anyone who owns a pair of KEF LS50s. Regarding its $1600 price tag, I'm enjoying it so much that I would gladly pay more. After all, I've invested in three or four other subwoofers in my quest for the "holy grail" match for my LS50s, and this KEF has finally delivered.

I have been looking for a tight subwoofer for a long time. Most subs focus on theater sound with a drawn-out base that will shake the room. The Kef KC62 perfect for my small studio sound room. Powered by my Hegal and paired with my JBL 4309s the tight base and that takes up small space sound is awesome. This sub is true stage sound for music lovers.

When I received this subwoofer it come in an amazon box, which, once opened, had the original KEF product box inside. The original box was badly damaged, and had clearly been opened already, and poorly at that. When I opened the KEF box, the subwoofer had been incorrectly packaged and the protective trays inside the package were half torn up and degraded. I pulled the subwoofer out and there were scratches on it and a dried up loogie (yes, someone had spit on it). Bottom line, this was clearly a return, and one that Amazon didn't even evaluate before they sent out the door again. I wonder how many times it had been returned before?? Not cool, Amazon, especially for a $1500 subwoofer. Obviously I returned it, but not before firing up the sub to see what it sounded like, as I was really curious to see if KEF had pulled off the impossible. I'm well versed in adjusting subwoofers to my space and after spending some time getting it calibrated, I had the subwoofer roaring. Truly impressive what KEF has pulled off, however, it just doesn't sound as good as traditional larger subs. It's cool that it's so compact and can fit into tiny spaces, but it's not the bass I'm looking for, and probably wasn't the bass that the previous purchaser that spit on it and returned it, was looking for either. I'd give the sub 3 stars for bass quality. I ended up going with the SVS SB 1000 Pro, which is a bit larger and not quite as aesthetically pleasing, but more than half the price and I'd give it 5 stars in sound quality. Getting a returned and damaged sub at full price was enough to scare me away from ever buying sound equipment from Amazon again. Would highly recommend another retailer, like Crutchfield for this kind of equipment. I still am very grateful for the services Amazon provides, but this purchase certainly left a bad taste in my mouth.

I use this subwoofer with my KEF LS50 Metas and they are a perfect match. When properly adjusted you can't tell where the bass from the LS50s ends and the KC62 begins. Crank them up and they will shake the whole house. You can really feel the bass.

JUNK!! Subwoofer has constant popping sounds. I have tried using the ethernet cable for faster internet connection to air play with Apple Music, still have popping sounds. I play music via Bluetooth and AUX with my record player, still have popping sounds. Heck, when I don’t play music at all, there are popping sounds. I unplugged all power source for a whole day and when I plug everything back in, still have popping sounds.

Very good for a small size subwoofer paired with a KEF XIO soundbar.

This is the smallest subwoofer I have ever owned. It sounds great with my LS50 Metas in my 2.1 system. It also looks great and has a very high build quality.

私のオーディオへの向き合い方ですが 趣味と言えるようなヘビーユーザーではなく 毎日の生活をサブスク音楽で少し豊かにしている程度です。 カジュアルに楽しんでる音楽のクオリティを上げたいな そういった視点から評価を書こうと思います。 KC62の導入前から同メーカーKEFの LS50 Wireless II で音楽を聴いています。 概ね満足していたものの 低音から中低音が互いに干渉していて不明瞭さが気になり 低音に関してももう少し下のところがでてくれればな、と感じていました。 サブウーファーに低音を預ければ この2点が解消されるのではないかと KC62を購入するに至りました。 本機が届きさっそく接続して鳴らしたところ このサイズでこんなに低いところがでるのか というのが最初に感じた率直なことです。 そして低音だけではなくメインスピーカーの 中低音のぼやつきが解消され 相対的に高音や中高音の音質も上がりました。 導入前の思惑通りで笑顔になります。 KEF Connectからハイパス、ローパス、ゲインを触り ここかなというところに設定しました。 曲によってあるいは自分の体調によっても聴こえ方が変わるので 完璧という位置はまだ確定しないです。 以下は私が良く音質評価につかっている曲での印象です。 詳細ではなく一番強く感じたことを記します。 ソースはWi-Fi接続でのSpotifyロスレスです。 「Bill Evans - Waltz for Debby」 クラブでの会話が明確に聞こえ 自分がその空間に居てる感覚です。 「Usher - Burn」 ひたすら艶めかしい。 低音の上にきらやかなボーカルが乗っているR&Bのお手本。 「西本智実 ボリショイ交響楽団 - ボレロ」 フィナーレの大太鼓4発がすさまじい。 リビングにパーカッション奏者がフルショットしている姿がみえる。 「Korn - Blind」 5弦ベースの最低音が恐ろしい。子どもが泣きそう。 「イルカ - なごり雪」 ドラムセットが見える。 挙げればキリがありませんが 毎日音楽を聴くのが一層楽しくなりました。 同メーカーのスピーカーとペアリングしているというのも 今回の感動には大きく寄与していると思います。 レビューをみていると他メーカーのスピーカーに繋いで なかなか四苦八苦してらっしゃる方もみられます。 2025年の個人的な買い物でベストです。 しかし、やはりオーディオはアナログでこそという感覚がありますから 「パワード」「デジタル」というところがいつ悪さをしないか気になります。 イギリス大手KEFのサポートを信じたいところです。

My original original review started with . . . . Works well with my LP12, Blu-ray and SADC player, Cyrus amp and Acoustic Energy tower speakers. . . . . but now the KC62 has totally changed my speaker setup and made the sound even better. It may sound unbelievable, but with the high pass frequency set near its highest value the KC62 would produce the whole bass range of the previously bi-wired AE towers as well as the intended subwoofer range, while disconnecting their bass halves would leave the AEs' mid/treble halves as effectively the upper end of bi-amped speakers. And it worked! The top end has improved massively in crispness just as bi-amping promises, while the whole bass range has a new beautiful relaxed, tonally rich quality. Plus, with all the positional clues coming from the improved higher frequencies, the sound picture may well be clearer now despite a single off-centre subwoofer providing so much of the frequency range. What a bonus!

Edit du 13/04/24: je mets 5 étoiles car il y a un paramètre sur (l'horrible) appli Kef Connect qui permet d'activer en permanence le caisson quand les enceintes Kef s'allume, mais ce n'est valable uniquement qu'avec des Kef connectés... Dommage pour ceux qui veulent le brancher sur un ampli. Commentaire d'origine : Connecté à mes LX2, ca donne tout simplement une autre dimension au son et ramène de la rondeur au LX2 qui ont un son plutôt plat (même en les réglant via l'appli). Vu la petite taille du caisson, on peut le poser sur le meuble TV, ce dernier ne vibre pas du tout malgré la puissance. J'ai un salon de 30m² et aucun problème, ca bombarde. 1000W ca chauffe, même à volume raisonnable, mais c'est acceptable. L'étoile en moins, c'est pour le même souci que certains décrivent : il faut "pousser" le volume sonore pour qu'il se réveille. C'est vraiment dommage qu'il faille l'utiliser à un volume soutenu, car quand on réduit le volume après, on ressent toujours l'apport du caisson, mais ce dernier se remet en veille au bout d'une minute (et le son redevient tout plat). Kef devrait augmenter la sensibilité (où donner la possibilité à l'utilisateur de le régler) pour la sortie de veille et ce caisson serait juste parfait !

Using this with the KEF LS-50 Meta has been the perfect match for me. I loved the KEF-LS 50 Meta's but this little sub adds the umph I wanted in the low end. It makes hip-hop sound the way it should. It does great for all other music types as well.

Al principio dude un poco en comprarlo por el precio y el tamaño, pensé que me quedaría a deber, yo contaba con un subwoofer krk de 10 pulgadas (que es bastante bueno), pero que sorpresa me lleve! Este sub alcanza frecuencias más graves y potentes que el krk y cualquier otro subwoofer que eh tenido anteriormente, el sonido es bastante limpio y preciso para mí sistema hi-fi, definitivamente vale cada centavo.
