Description
MM84TB – 8" Tower Speakers with ATAC™ Technology
Advanced Tower Array Construction • Black • Pair
Memphis Audio MM84TB tower speakers feature ATAC™ (Advanced Tower Array Construction), a curved tweeter array design inspired by concert line-array systems. This compression-horn-free approach is engineered to deliver wide dispersion, strong output, and long-term durability in demanding marine and saltwater environments.
Overview
ATAC™ Design for Clear, Wide-Angle Projection
Traditional compression horn tower speakers require the horn to intersect the woofer, reducing effective cone area and efficiency. The ATAC™ design eliminates this limitation by using a curved tweeter array mounted across the front of the speaker, allowing the woofer to remain fully sealed and operate more efficiently.
- Advanced Tower Array Construction (ATAC™) with curved array tweeter bridge.
- Three-tweeter line array optimized for wide dispersion.
- Designed to outperform traditional compression horn tower speakers.
Maximized woofer surface area improves output and midbass while maintaining clarity at a wide range of listening angles behind the boat.
Construction
Fully Sealed for Marine Durability
The MM84TB allows the woofer to be fully sealed, helping prevent water and debris intrusion. Combined with sealed electrical connections and an IP66 rating, this design supports long-term reliability in marine and saltwater applications.
- ASA plastic enclosure.
- Sealed electrical connections.
- Stainless steel array grille.
- IP66 rated for water and dust resistance.
