非常大的磁钢，磁钢越大，磁性越强，喇叭所能承受的功率越大。铸铝盆架，刚性强度比普通铁皮盆架更好，更能保证喇叭震动时的稳定性，减少低频失真。

非常厚的弹波，长冲程大声压的保证：

箱体内部非常牢固的加强筋，保证大动态的时候箱体谐振降到最低。内部四周都铺满吸音棉，用料十足，连喇叭线都用吸音棉包裹，减少喇叭线震动对低频的影响，细节做得非常到位：

内置巨型环牛变压器，采用比D类功放成本更高的AB类功放，低音更清晰低沉。
Built-in 300-watt RMS (500-watt peak) amplifier
A 300-watt RMS (500 watts peak power) amplifier lets you play your Studio 550P subwoofer at body-quaking levels without any room-vibrating reverb or excessive heat output. A built-in limiter extends this ability by preventing distortion that can arise out of sudden peaks, taking the audio from merely impressive to completely immersive.

10-inch (250mm) PolyPlas low-frequency transducer
The Studio 550P features a 10-inch (250-millimeter) cone made from lightweight yet rigid PolyPlas cone material. For the listener, this structure means powerful heart-thumping bass with such low distortion that individual sounds remain both accurate and articulate, even at sustained low frequencies. This is the kind of bass that takes surround sound from simply a listening experience to a seemingly tangible, robust environment.

Sealed enclosure
Power and accuracy normally do not go hand in hand. The Studio 550P, however, is by no means a mere normal subwoofer. It features a sealed enclosure that acts to control the woofer cone’s motion, thus providing consistent, reliable sound that remains smooth and rich even at the deepest of frequencies.

Forward-firing transducer
The Studio 550P places you in the center of the action by sending the action straight at you via a powerful, forward-firing cone. Sound travels directly to your ears without reverberating off the walls or bending around the furniture. This is bass in its most potent form, from a subwoofer versatile enough to be placed in the middle of the room or against a wall.

Adjustable crossover frequency and phase control
A phase switch ensures that the action of the Studio 550 subwoofer’s transducer moves in sync with your main speakers. As a result, the subwoofer’s low frequencies blend seamlessly with the sound coming from the main speakers, regardless of where you place the subwoofer in a room. Furthermore, an adjustable crossover-frequency control lets you optimize the subwoofer for a variety of main/satellite speaker choices.

LFE and line-level inputs
A choice of LFE and line-level inputs lets you either use or bypass the subwoofer’s internal crossover circuits for bass-boosting versatility. This option provides greater flexibility in how you use the Studio 550P while ensuring noise-free connections to virtually any type of audio/video amplifier.

Metal floor spikes included
Unwanted interaction between the subwoofer and the floor can cause distortion – but the Studio 550P includes an array of metal spikes to reduce distortion. The use of such spikes also creates clean sound by placing a cushion of air between the speaker and anything that could potentially disturb its pristine low-frequency waves.

内置300瓦RMS（500瓦峰值）放大器
一个300瓦RMS（500瓦峰值功率）放大器，可以让你在身体发抖的水平发挥你的工作室550P的低音炮没有任何余地振混响或过热输出。内置的限扩展了防止可能出现突然出峰的失真，同时将音频从单纯的令人印象深刻的，完全身临其境的这种能力。

10英寸（250毫米）POLYPLAS低频换能器
工作室550P拥有由轻质而坚固的锥形POLYPLAS材料制成的10英寸（250毫米）锥。对于监听器，这种结构意味着这样的低失真，低频声音仍然既准确又有细节，即使在持续的低频强大的心脏，重低音。这是一种低音的需要环绕声从单纯的聆听体验到一个看似有形的，可靠的环境。

密封外壳
力量和准确性通常不会齐头并进。工作室550P，但绝不是一个单纯的普通低音炮。它具有密封外壳，其作用是控制低音锥的运动，从而提供稳定，可靠的声音，即使在最深的频率保持光滑和丰富。

前向发射换能器
工作室由550P通过一个强大的，前瞻性的发射锥在你直接发送操作将您在活动的中心。声音直接传到你的耳朵回荡没有的墙壁或周围的家具弯曲。这是在其最有效的形式的低音，从低音炮多功能足以被放置在房间的中央或靠墙。

可调节的分频器频率和相位控制
A相开关确保工作室550低音炮的换能器的动作同步移动与主音箱。其结果是，低音炮的低频与主音箱传来的声音完美融合，无论您放置低音炮在一间客房。此外，一个可调节的分频器频率控件，可以优化低音炮的各种主/卫星音箱的选择。

LFE和线路电平输入
LFE和线路电平输入的选择可以让您无论使用或绕过低音炮的内部交叉电路对低音提升通用性。此选项提供了如何使用Studio 550P，同时确保无噪声连接几乎任何类型的音频/视频放大器的更大的灵活性。

包括金属地板尖峰
低音炮和地板会导致失真之间不必要的交互 - 但工作室550P包括金属钉阵列来减少失真。使用这样的尖峰也放置的气垫扬声器以及任何可能干扰其原始的低频波之间产生干净的声音。
