RCF HD 35-A Active 1400W 15 Inch Two-Way Powered Speaker

RCF HD 35-A: High-Output 15" Powered Top for Demanding Gigs

The RCF HD 35-A is an active two-way speaker built for serious PA work where clarity, punch, and reliability matter every night. Delivering up to 132 dB max SPL from a 1400 Watt peak Class-D amplifier, it couples a 1.4" titanium compression driver with a 3.0" neodymium voice coil to a 15" high-power woofer, giving DJs and live engineers the mix of vocal projection and low-frequency authority they expect from a modern 15" top.

A powerful on-board DSP with FiRPHASE processing manages crossover, equalization, soft limiting, and protection. The 800 Hz crossover point lets the ND840 compression driver handle more of the critical midrange, tightening vocal imaging and improving intelligibility, while the woofer focuses on mid-bass and punch. The 90° × 60° constant directivity horn spreads that sound evenly across the room so people at the edge of the dancefloor hear the same mix as the center.

Under the hood, a fanless Class-D amplifier module with convection cooling and a solid aluminum structure keeps weight down and heat under control without adding fan noise. The HD 35-A’s PP composite enclosure, steel grille, multiple M10 rigging points, and 35 mm pole mount make it at home on stands, on top of RCF subs, or flown for more permanent PA installations.

Control Modes for the RCF HD 35-A

The HD 35-A uses an integrated DSP section to manage crossover, protection, and tone shaping, keeping operation straightforward for both DJs and engineers.

• Input Stage: Accepts balanced or unbalanced signals via XLR and jack input connectors, with an XLR output for linking to additional speakers.
• Mic/Line Switching: A Mic/Line control changes input sensitivity between approximately -32 dBu (mic) and -2 dBu / +4 dBu (line), so the HD 35-A can be used with mixers or directly with a microphone when needed.
• Level and Boost: A main Volume control and Boost switch allow quick adjustment of overall level and a contour for added presence or low-frequency energy, depending on the application.
• Digital Processing: DSP handles the 800 Hz crossover, FiRPHASE alignment, equalization, soft limiting, and system protections so the full 1400 W peak / 700 W RMS amplifier power can be used confidently.
• Protection and Limiting: Thermal and RMS protections with a Soft Limiter help prevent driver damage when the system is pushed near its limits.
• Power and Cabling: Power is connected via Powercon IN/OUT, simplifying daisy-chaining power between multiple HD 35-A speakers on a common circuit.

Expanded Details on the RCF HD 35-A Active Speaker

FiRPHASE Processing and a New Perspective on Linearity

RCF’s advanced FiRPHASE technology is at the core of the HD 35-A. Using proprietary digital FIR filters, the processing linearizes phase response so transients remain intact and stereo imaging feels more natural. The result is a system that maintains clarity and focus across the listening area, which is especially important when vocals, keys, and high-frequency content need to cut through dense mixes.

ND840 Titanium Compression Driver with 800 Hz Crossover

The ND840 compression driver uses a pure titanium diaphragm and a 3" neodymium voice coil. By crossing over at just 800 Hz, the driver handles more of the vocal and midrange band than typical designs, improving impulse response and decay while keeping distortion low. For DJs and engineers, that means announcements, lead vocals, and horn instruments stay intelligible even when the system is pushed hard.

High-Power 15" Woofer for Punch and Control

Low-frequency duties are handled by a 15" woofer with a 3.0" voice coil. The design focuses on linear response and precise mid-bass reproduction, so kick drums and bass lines translate with authority without overpowering the mix. Combined with the horn-loaded top end, the woofer helps the HD 35-A serve as a versatile main for DJ events, live music, and speech-driven gigs.

Class-D Amplifier Power with Fanless Convection Cooling

The internal amplifier delivers 1400 W peak / 700 W RMS total power, split into 400 W peak / 200 W RMS for the high frequencies and 1000 W peak / 500 W RMS for the low frequencies. Built on RCF Class-D technology, the module offers fast transient response and high efficiency. The solid aluminum structure doubles as a heat sink for fanless convection cooling, eliminating fan noise and moving parts while keeping the electronics stable in demanding environments.

Cabinet, Hardware, and Rental-Proof Construction

The HD 35-A’s PP composite cabinet is molded to reduce vibrations even at high volume. A steel front grille protects the drivers, while one top handle and two side handles with rubber grips make loading easier. The cabinet shape supports monitor use, and hardware points (1 × M10 top, 1 × M10 bottom, 2 × M10 side) plus a 35 mm pole mount give installers and rental houses multiple mounting options for flown or pole-mounted rigs.

Dimensions, Weight, and Truck-Friendly Footprint

With a height of 714 mm, width of 442 mm, depth of 397 mm, and a weight of 22 kg (48.5 lbs), the HD 35-A balances output with portability. Shipping dimensions of roughly 750 × 440 × 480 mm and a package weight of 24.5 kg make it straightforward to pack into standard trucks and storage spaces for rental and touring workflows.

How to Deploy the RCF HD 35-A in the Field

The RCF HD 35-A is designed to drop into many different roles, from DJ mains over subs to flown tops in a fixed install. Start by defining the role: stand-mounted main, sub-top stack, flown cabinet, or floor monitor.

• On Stands or Poles: Use the 35 mm pole mount insert to place the HD 35-A on sturdy stands or on poles above compatible RCF subs. Aim the cabinet so the 90° × 60° horn covers the audience evenly.
• Over RCF Subwoofers: Stack HD 35-A tops over SUB Series subwoofers for full-range DJ or band systems. Set input sensitivity to Line and feed from your mixer’s main outputs, using the XLR link to daisy-chain multiple tops.
• Monitor or Side-Fill Use: Use the cabinet’s multi-purpose shape as a floor monitor or side-fill. Select the appropriate level and Boost setting to match the stage mix and keep feedback under control.
• Flown or Installed Systems: Take advantage of the M10 hardware points (top, bottom, and sides) with appropriate rated rigging hardware for flown or bracket-mounted configurations in clubs, theaters, and houses of worship.
• Signal and Power: Connect audio via XLR or jack, use the Mic/Line switch to match source level, and power the cabinet with Powercon IN, daisy-chaining with Powercon OUT where appropriate and within circuit limits.
• System Tuning: Start with Volume at a conservative setting and Boost off, then increase level until you reach the desired SPL. Let the DSP, FiRPHASE processing, and Soft Limiter manage protection while you balance the mix.

Deploy HD 35-A tops on stands, over subs, or in flown clusters and you get consistent, articulate coverage that keeps Chicago rooms dancing without sacrificing vocal detail.
