Owner Insights

We analyzed real musician discussions from forums and Reddit to find what players love, question, and tweak about Sx300 / Electro Voice.

Setup and maintenance

  • A typical 50 to 100-watt home receiver is sufficient for garage use, allowing individual connection of each speaker with A/B outputs.

    Source
  • Owners are advised to ensure polarity is wired correctly to avoid bass cancellation issues.

    Source
  • Owners recommend using SpeakOn cables for connection, but adapters exist for amps without SpeakOn ports.

    Source
  • A recommended signal chain for this setup: Mixer > Crossover > High-Mid output to amp, Subwoofer out to sub > Amp outputs to tops.

    Source

Features and functionality

  • SX300s are 8-ohm speakers, allowing for two speakers per channel at a 4-ohm load if using a pro audio amp.

    Source
  • SX300 speakers are designed for bass down to 80 Hz, offering adequate low-end for non-subwoofer setups.

    Source
  • Bluetooth functionality can be added via a separate receiver, offering flexibility without relying on amp-integrated Bluetooth.

    Source
  • The EKX-15SP active sub only powers itself; an external amp is required for powering the SX300 passive tops.

    Source

Comparisons

  • QSC RMX series amps are favored for their clean sound and power, with models like RMX 850 available used around $180.

    Source
  • Pyle amps are noted as a budget-friendly option with built-in Bluetooth, suitable for non-critical home setups.

    Source

Use cases and applications

  • For a balanced stereo PA rig, use one SX300 and one subwoofer per side, utilizing a stereo electronic crossover set between 100-120Hz.

    Source
  • Using only two SX300s is advised for better stereo imaging and avoiding comb filtering in garage setups.

    Source
  • For outdoor electronic music events, more PA power is needed to create a visceral experience, especially since outdoor settings lack sound containment.

    Source

User experience

  • Despite their 300W rating, many owners find 100W sufficient to achieve high sound output levels.

    Source
  • Combining four SX300s can lead to phase issues and poor sound quality if not set up as satellite speakers.

    Source

Mods and upgrades

  • Some owners suggest adding an active subwoofer for a more profound bass impact, though this adds complexity and cost.
