Audio Technica AT-SP3X Bookshelf Speaker Record Player Bluetooth Monitor Speaker [Active RCA Input Multi-point Support PC TV Music Listening] Black

MacBook AirにDAC（AZLA A150）を介して接続し、Amazon music unlimitedを聴くために購入。当初Presonus Eris3.5 2nd Gen Whiteを探していたが入手困難であることがわかり本機を選択。Eris3.5に搭載されているオートパワーオフとヘッドホンジャックが本機にはなく妥協しての購入だった。しかし電源ON無入力時の待機電力をメーカーに問い合わせたところ、わざわざ実測してくれて、電源ON無入力時1.2W、電源OFF待機電力0.16Wとの報告を受けた。極めて低い消費電力なので、これなら付けっぱなしでも電気代は気にならないことが判明。本機は電源スイッチが右外パネルにあり、しかもBluetoothとRCA入力のセレクターも兼ねているため、操作するためにはいちいち覗き込む必要がある。しかし、RCA入力のみで電源スイッチ操作不要となればこの難点は気にならなくなった。それにしてもメーカーの誠意ある対応には感激した。流石は町田市成瀬の企業！ヘッドホンジャックについては、DACの出力にCOOIDEAのオーディオスイッチを繋ぎ、深夜は同社のヘッドホンATH-M50xに切り替えて使用している。音色がM50xと統一感があって好感が持てる。 スピーカースタンドはサイズがぴったりで高さを稼げるAlterzone社のWhiteを使用。これで机上の面積を確保するとともに、机面からの音の反射を抑えた。後部壁面からバスレフダクトを約６ｃｍ離して設置した結果、サイズの割に量感ある低音を奏でてくれている。さすがに重低音は無理だがデスクトップの近接試聴にはこれで十分。ハイレゾの透明感とレンジの広さを十分堪能できるうえ、カスタマーサポートの神対応も相まって満足度はとても大きい。Presonusなどの海外製を購入していたら、この満足感は得られなかっただろう。今後もオーディオテクニカ社の製品を愛用していきたい。

Bluetoothも繋がりやすい。音も良い。これでレコード聞いてますが、自分のような初心者には十分です。音量は大きめにしてます。

同価格帯の他のものと比べたわけではないので完全主観ですが、満足してます。音に変な味付けがないのがいいです。あと、audio technica というロゴもいいです。

気に入っています。 スピーカー台の購入も検討中です。

同じくオーディオテクニカ製のAT-LP60XBTというレコードプレーヤーとセットで買うのがオススメです。 同じ会社なので相性抜群です。

普段、アップルミュージックを使っています。 iPhone の中にあるイコライザーを使うと音が格段に良くなります。（プライムミュージックだとEQは使えない） Bluetooth接続、厚めの本の上に乗せてますが低音もしっかり出ています。 JBLのポータブルスピーカーやBOSEのオシャレな置き型スピーカー、アンプが必要な高額なスピーカーも検討していたけど、これを選んで正解でした。

コンパクトなのに大出力 省スペースの場所に置けて最高です。

These are amazing speakers! They work via bluetooth and wired connection. I even bought the stand "Audio-Technica AT-ST3 Speaker Stand" afterwards and that made the sound even better as I had the speakers on a hollow cabinet below ear level. Now the speakers aim at an angle towards the ears for optimal listening enjoyment, Thank you for making such a great product!

Was using Klipsch "The Sevens" powered speakers, which have good sound but are unreliable. First pair were DOA, second pair failed within two years. Got these Audio-Technica AT-SP3X to fill the gap until the Klipsch can be fixed / replaced. With cheap bookshelf speakers, the question always is: will they turn out to be just thin, tinny computer speakers? VERY FAR FROM IT! Immediately I got them fired up, just - wow!! I mainly listen to jazz and classical and they're more than loud enough with the volume knob not even half way around its travel. At full volume, they're WAY too loud for general listening. They have a subtle, spacious, captivating sound - simply a pleasure to listen to. I'm running them on heavy speaker stands, spiked through carpet into wood flooring, in a 2.5 meter equilateral triangle from the listening position, about 40 cm from the side walls (bookshelves), 2.5 meters from the back wall (bookshelves). Sources are via Bluetooth from a laptop and wired phono from a CD player. Click the ON/OFF button to toggle the inputs through Bluetooth (two sources) and wired. (Holding the button down for 3 secs puts the speakers into standby.) A little LED on the button changes from blue for Bluetooth input (with a little boop-boop sound confirming connection), green for wired and red for standby. Bluetooth pairing is fuss-free. They have the speaker pair's serial number on the back of each unit and the manufacturing date on the bottom, i.e. they're likely matched pairs. The only downsides I can see are: 1. Lack of a remote control, meaning you have to walk over to the primary speaker to adjust volume or change input. 2. Primary (right) speaker, with controls and inputs, can't be switched from R to L. 3. Bluetooth running only the most basic SBC codec (although sounding absolutely fine). At this price, Audio-Technica have pared them down to the essentials and made the right choices. Bluetooth latency tests on youtube indicate about a 160 millisecond audio delay. The AT-SP3X specs give frequency response as 55-20,000 Hz but, playing youtube speaker test tracks, 40 Hz is clearly audible. Response then gently falls away through 28 Hz (just audible) to 20 Hz, where the woofer cones are still vibrating but inaudible. The listening reality, after they're fully burned in (several weeks), is that there's absolutely NO lack of bass from these speakers, despite their ludicrously small size. Even classic 90s hip-hop CDs sound pretty good. The floor does vibrate... if maybe not quite the windows! Search youtube for Grilled Cheese and Bacon Joey DeFrancesco for a bass-heavy jazz track. Search youtube for Thomas Ospital A l'ombre des Halles for a brutal speaker workout. Starts mysterious, spooky... The madness begins around the 8 minute mark! These speakers do expose poor recordings mercilessly (although poor recordings of amazing performances always trump amazing recordings of poor performances). With quality recordings, they shine - natural presentation, big sound, great staging. Their tiny size truly is deceptive. The supplied inter-speaker connecting cable is only 2 meters long so I'm using an old 6.5 meters long Atlas Hyper 2.0 speaker cable to reach down to the floor and between the speaker stands. A bit long but works fine - no loss of volume or power. (Banana plugs don't fit the AT-SP3X's cable clamps. An effective adaptation from banana plug to cable clamp: 1.75 mm Ø solid copper house wire wound around the banana plug prong a few times and then bent parallel, the wire and prong shrouded with heat shrink tubing to prevent the plugs shorting together and the free wire end flattened down to about 1 mm thickness to maximise contact area when pushed into the AT-SP3X's cable clamps.) My mind is blown by these speakers. Totally recommended. Edit (thirteen weeks later): If you want to impress your friends with gigantic, outrageously expensive speakers, these won't do it! Their compactness is so unassuming, doesn't dominate the room like larger speakers and, as near-point sources, must be contributing to their superb sound stage. A reasonable measure of a sound system's quality is how much music you actually find yourself listening to on it. The AT-SP3X's sheer musicality just keeps drawing me in. Waste of time going back to the Klipsch now. These do it for me. Life is too short.

Thankyou all works well now. Thankyou lovely sound.

These sound great for small bookshelf speakers. Really impressive sound quality and plenty of bass response. I bought them for my wife to match her record player she wanted for Christmas. I had to set it all up for her and both Bluetooth and the rca connection work well. Definitely glad I went with the matching speakers and not a different brand. They came with a few international plug adapters if anyone travels or is outside the USA you should be able to use these anywhere you are.

Amazing sound!! Best speakers I've ever had!

Très bien
