Welcome to the REL Family

Congratulations on your purchase of a new REL Tzero MkIII. While the Tzero MkIII is one of our most

affordable models, it possesses a great deal of the character, unique features and sound quality of our

larger and costlier models. While its size suggests something not unlike a multimedia subwoofer designed

to, at best, suffer connection to a shoddy computer-based Bluetooth or similar system, the reality is that

this is a full, proper REL.

Significantly, it is the least expensive model that includes our High Level circuit which is key to obtaining a

perfect blend with one’s speakers as it attaches to your amplifier’s or receiver’s speaker outputs, thus

allowing the entire sonic signature of your system to be built forward ensuring that REL and system speak

as one.

The primary upgrade on the MKIII lies in the upgrades brought to the downfiring active driver. MKIII uses a

damped aluminium driver to achieve exceptional rigidity which goes a very long way toward producing a

sound that is far more impactful than its diminutive stature would suggest. The damping on the rear of the

cone ensures that the driver does not ring and result in a lightweight presentation. Compared with earlier

models of the Tzero MkIII, the MKIII is far more powerful and impactful.
