The TOA HX-7 is a professional compact two-way speaker system engineered with advanced wave front control technology to deliver exceptional directivity control and speech intelligibility in acoustically demanding environments. Designed as a true line array element, the HX-7 employs sophisticated acoustic engineering to maintain consistent coverage patterns across an extended frequency range, making it the ideal solution for medium to large venues plagued by long reverberation times, high ambient noise, or challenging sightlines.

Unlike conventional speakers that lose pattern control at lower frequencies, the HX-7's wave front control technology maintains precise directivity across the critical speech intelligibility range, dramatically reducing unwanted reflections from walls, ceilings, and floors. This focused energy delivery ensures announcements and program material cut through background noise while minimizing acoustic feedback and room-induced coloration—essential in reverberant spaces like gymnasiums, natatoriums, worship facilities, sports arenas, and transportation terminals.

The HX-7's true line array design enables multiple units to be vertically stacked or arrayed, creating a coherent acoustic source with extended throw distance, increased SPL capability, and improved vertical coverage control. Each HX-7 features an enhanced high-frequency compression driver for superior vocal clarity and power handling, housed in a compact, lightweight enclosure that simplifies rigging and installation while maintaining professional-grade durability.

Optimized for medium-sized venues including houses of worship, educational auditoriums, multi-purpose gymnasiums, corporate conference centers, and sports facilities, the HX-7 delivers the performance of large-format line arrays in a more compact, cost-effective package. The speaker's efficient design, professional connectivity options, and flexible mounting system make it equally suitable for permanent installations and portable applications requiring consistent, high-quality sound reinforcement.

Backed by TOA's industry-leading 5-year warranty and decades of commercial audio expertise, the HX-7 represents a proven solution for environments where conventional speakers fail to deliver adequate intelligibility and coverage.

Frequently Asked Questions

Q: How many HX-7 speakers do I need for my venue? A: This depends on throw distance, vertical coverage angle, and desired SPL. A 2-4 box array covers 40-80 feet; 4-8 boxes cover 60-120 feet; 8-12 boxes cover 80-150+ feet. Consult a professional integrator or TOA for specific recommendations based on your venue.

Q: Can a single HX-7 be used without arraying? A: Yes, the HX-7 functions as a high-quality standalone speaker for small to medium venues. Arraying is optional but provides significant benefits for larger spaces or long throw distances.

Q: What's the difference between the HX-7 and conventional speakers? A: The HX-7 features wave front control technology for extended directivity across the frequency range, true line array coupling capability, and optimization for reverberant spaces. Conventional speakers have wider, less-controlled dispersion and don't couple acoustically when stacked.

Q: Do I need special software to design an HX-7 array? A: While you can design basic arrays manually using geometry and coverage formulas, acoustic prediction software is highly recommended for optimal results. Contact TOA for compatible software options or array design assistance.

Q: What amplifier is recommended for the HX-7? A: Use professional multi-channel DSP amplifiers rated 400-600W @ 8Ω per channel. Brands like Lab Gruppen, Powersoft, QSC, Crown, and others with comprehensive DSP are ideal. Each HX-7 requires a dedicated amplifier channel.

Q: Can HX-7 arrays be used outdoors? A: The HX-7 is designed for indoor use only. For outdoor applications, use weather-resistant covers if temporarily exposed, or consider dedicated outdoor-rated speaker systems from TOA's product line.

Q: How do I calculate splay angles for my array? A: Total vertical coverage needed ÷ number of boxes = average splay. Use J-curve (tighter angles at top, wider at bottom) for optimized coverage. Acoustic modeling software provides precise splay recommendations.

Q: Is professional installation required? A: For overhead rigging, absolutely yes—use only certified professional riggers. For wall/ceiling mounting or portable setups, experienced installers with proper training can perform installation safely. Always follow safety regulations and building codes.

Q: Can I mix HX-7 with other TOA speakers in the same system? A: Yes, but HX-7 arrays should be kept separate from other speaker types for optimal performance. You can use other TOA models for front-fill, delays, or other zones while maintaining HX-7 arrays as main PA.

Q: What maintenance does an HX-7 array require? A: Regular visual inspections, annual professional rigging inspection, periodic cleaning, connection checks, and system measurements to verify performance. See the Maintenance & Service section for detailed schedules.
