GoldenEar SuperSub X
Compact yet ferocious, the SuperSub X delivers deep, clean bass, striking low-end detail and cinematic impact that belies its compact cabinet. HomeTheaterHifi found it smooth and room-filling to near 20Hz, while Home Cinema Choice praised its controlled, visceral movie performance. Its inertially balanced four-radiator design makes a muscular, refined choice for space-conscious theaters.

Pros
Delivers potent, clean and detailed bass with strong in-room extension approaching 20Hz.
Produces room-loading, visceral cinematic dynamics far beyond what its compact dimensions suggest.
Rigid, vibration-free cabinet remains controlled under demanding playback levels.
Small enclosure is easy to accommodate and particularly practical for multi-sub installations.
Cons
Fast, rhythmically demanding bass can sound slightly sluggish and less crisply defined than leading rivals.
Feature set omits high-level inputs, phase control, remote control and onboard EQ.
May require careful placement to achieve optimal room coupling and smooth response.

What Reviewers Are Saying
Assessments of Build Quality, Usability, and Overall Propositions.
Bass
91/100
Reviewers find the SuperSub X potent, clean and unusually detailed for its compact dimensions, with strong in-room output approaching 20Hz in one medium-sized room. It delivers devastating movie effects and bone-jarring impact, although Home Cinema Choice heard some sluggishness on fast techno and less sharply defined kick-drum beats than the best alternatives.
Integration
89/100
In a medium-sized theater, the SuperSub X was said to couple well with the room, providing smooth response and even coverage while filling the space at appropriate levels. Home Cinema Choice also found film effects visceral and believable rather than overblown or out of scale, though its occasional loss of low-end cohesion at very high tempo limits the sense of complete effortlessness.
Dynamics
92/100
The compact GoldenEar produces notably forceful cinematic dynamics: reviewers describe it as thrillingly ballistic, able to load a room and hit much harder than its size suggests. It also combines that physical impact with good low-level subtlety, although extra headroom from adding a second unit further improved impact and seat-to-seat consistency.
Build Quality
92/100
The cabinet is described as built like a small tank, with substantial weight and no audible cabinet vibration even under severe provocation. Reviewers also praise its solid construction and furniture-grade, Art-Deco-inspired finish.
Features Usability
82/100
Its compact enclosure can make placement and multi-sub deployment easier, and it includes DSP control, auto signal sensing, LFE input, and adjustable line-level low-pass filtering. However, Home Cinema Choice notes the absence of high-level inputs, phase control and remote control, while rivals at this price may add onboard EQ.
Value for Money
85/100
At its original $1,249 price, Audioholics considered it in line with other high-performance ultra-compact competitors. The value case is tempered by Home Cinema Choice, which found the feature set somewhat sparse next to the slightly pricier SVS SB-13 with onboard EQ.
