ASHLY IS3.8P 8 x 3" Passive Dual-Z Focused Directivity Column Speaker (Single, Black)

Product Overview

The Ashly IS3.8P is a passive Dual-Z Focused Directivity column speaker purpose-built for commercial AV installation. Featuring 8 x 3" neodymium drivers in a compact all-metal enclosure, it delivers consistent front-to-back coverage with exceptional speech intelligibility — ideal for conference rooms, houses of worship, and corporate event spaces. Its switchable 8 Ω / 32 Ω impedance makes it compatible with both standard low-impedance and multi-speaker distributed configurations without transformers, simplifying commercial column speaker installation. Pair it with an SP subwoofer and an Ashly DSP amplifier for a complete, optimized commercial AV system.

Product Description

The IS3.8P is part of Ashly's IS Series — slim, high-output column arrays engineered for venues where speech intelligibility and aesthetic discretion both matter. The eight 3" neodymium transducers are arranged in a linear column array that produces ultra-wide horizontal dispersion (170°) paired with controlled vertical directivity (25°), directing sound where audiences are rather than toward reflective ceilings and floors. This focused pattern control yields consistent SPL from the front to the back of the room, reducing flutter echo and reverberation — a significant advantage in hard-surfaced commercial spaces such as airport terminals, lobbies, and multipurpose auditoriums.

The durable, chip-resistant polymer-coated all-metal enclosure is built for permanent installation as well as portable use. The dual-impedance switch (8 Ω / 32 Ω) eliminates the need for external transformers in distributed systems with multiple speakers per amplifier channel. Two IS3.8P units can be stacked vertically using the optional ISJP2B joining plate to extend throw for larger venues. The speaker ships with flush wall-mount brackets included; pole, tripod, and tilt wall mounts are available as optional accessories. Speaker Voice Presets for Ashly Protea and AquaControl DSP processors are available for download, enabling calibrated, optimized performance out of the box when used with Ashly amplification.

Frequently Asked Questions

Can I use the IS3.8P on a 70V distributed system?

The IS3.8P is a low-impedance passive speaker (8 Ω / 32 Ω). It is not 70V compatible natively. For 70V constant-voltage systems, use the Ashly AW series speakers with built-in transformers, or add external line-matching transformers.

How many IS3.8P speakers can I run per amplifier channel?

In 32 Ω mode, you can run four speakers in parallel on a single 8 Ω amplifier output without overloading the amplifier. The dual-impedance design eliminates the need for transformer matching in these configurations.

Can two IS3.8P speakers be stacked together?

Yes. Use the optional Ashly ISJP2B joining plate to stack two IS3.8P columns vertically for increased throw and SPL in larger venues.

What amplifier is recommended with the IS3.8P?

Ashly Protea and AquaControl DSP-enabled amplifiers are the recommended pairing. Pre-optimized Speaker Voice Presets are available for download, ensuring calibrated, consistent performance.

Is the IS3.8P suitable for outdoor use?

The IS3.8P is designed for indoor commercial installation and portable use. It does not carry an IP weather-resistance rating. For outdoor applications, consider the Ashly AW series IP54-rated surface-mount speakers.

What mounting options are available?

Flush wall-mount brackets are included in the box. Optional accessories include the ISFWB3.8 fixed wall bracket, ISPM1B (1-foot) and ISPM6B (6-foot) speaker poles, ISTR7B 7-foot tripod stand, and ISTWMB tilt wall mount.
