Description
If you're looking for a tough, clear-sounding paging horn that works indoors or out without breaking the bank, the Bogen SP158A is a proven choice. This compact 15-watt reentrant horn gives you excellent voice intelligibility whether you're making one-way announcements or using it in two-way talk-back systems.
Built with sturdy all-metal construction and a weatherproof design, it stands up to dust, moisture, and rough handling in warehouses, schools, factories, construction sites, transportation hubs, and outdoor recreational areas. Its 8-ohm impedance makes it perfect for direct connection to standard amplifiers - no transformer tap adjustments needed.
Minor note: Because it's strictly 8-ohm, it's not the best pick if your system runs on 70V or 25V constant-voltage lines (for that, look at the matching SPT15A). But for most direct-drive amplifier setups, it's hard to beat.
