The S3A is one of ADAM’s most famous models and is found in many of the most prestigious recording studios all over the world. The successor of this world famous model is the S3X-H, a monitor second to none within its size and price point.

Extended information

Unlike the S3A, the new X-model incorporates a 4” HexaCone™-midrange as part of the redesigned construction to further improve the musically most important midrange. This new design provides more detail with improved radiation characteristics while presenting a musically coherent sound.

To produce deep, tight bass both woofers now work within the same frequency range and radiate symmetrically. This allows for a problem free installation in any multi-channel application.

Optional digital input
All SX-models (except the S1X) can be optionally retrofitted with a 24 bit/192 kHz D/A Converter featuring an AES/EBU (XLR) and a SPDIF (RCA) inputs as well as a R/L/Mono switch.

The front panel
Six controls can be found on the new front panel. Input sensitivity is handled by two controls. One control allows for coarse settings (-20dB to +8dB), while the second is used for fine tuning in 0.5dB steps, ranging from -1.5dB to 2dB.
There are two controls for the lower frequencies. One is an equalizer at 80 Hz that boosts bass response sometimes desirable in popular music. The second is a shelf filter that allows the engineer to alter the frequencies below 150 Hz.
High frequencies can also be adjusted by two different controls. The first alters the high frequency volume (-2dB to +2dB), while the second is a shelf filter for frequencies above 6 kHz. Both the high and low shelf filters can raise or lower ±4 dB progressively within their frequency band.
