Viking Speaker (Square) - 100 ohm - 2.5in. in. Diameter - Q171230

Viking Electronics Q171230 2.5-Inch Square 100-Ohm Replacement Speaker

Overview

The Viking Electronics Q171230 is a 2.5-inch square, 100-ohm speaker designed as a direct replacement component for Viking intercom, paging, and entry-system products. If you are maintaining or repairing Viking-branded equipment that originally shipped with the Q170200 speaker, the Q171230 is the current replacement part — same form factor, same impedance, drop-in compatible. It ships with 26 AWG pre-attached wires, which keeps field splicing straightforward and avoids the guesswork of sourcing correct gauge wire separately.

This is a spare part for service technicians and integrators maintaining installed Viking systems, not a standalone audio product. Pair it with the broader Viking Electronics parts catalog when building a service kit for multi-site maintenance contracts.

Key Features

• 100-Ohm Impedance: Matched to Viking intercom and entry-phone circuits. Using a mismatched impedance speaker — even a physically identical one — can load the amplifier incorrectly and degrade audio quality or damage output stages. The Q171230 hits the correct load for Viking-designed circuits without any re-engineering.
• 2.5-Inch Square Form Factor: The square profile fits Viking enclosures and speaker cutouts dimensioned for the Q170200. No bracket modifications, no re-cutting panels — swap and reassemble. Round aftermarket speakers of nominally similar diameter will not seat correctly in square cutouts.
• 26 AWG Pre-Attached Wires: Fine-gauge wire is appropriate for the low-current audio signals on intercom lines. Having leads factory-attached means one less connection point in the signal path and faster bench or field replacement. Strip, connect, done.
• Direct Q170200 Replacement: Viking explicitly designates the Q171230 as the successor to the Q170200. If you are sourcing a replacement and your parts list references the older part number, Q171230 is the current equivalent — no compatibility research needed.

Integration & Compatibility

The Q171230 is designed for use in Viking intercom and door-phone systems where the Q170200 was the original installed speaker. It is tagged in Viking's own spare-parts store under the E-30-EWP product line, indicating compatibility with that entry-phone family. If you are servicing a Viking unit not in the E-30-EWP line, confirm the original speaker impedance before ordering — 100 ohms is not universal across all Viking products. For broader access control and entry-system components, verify the speaker impedance requirement in your unit's service manual before substituting.

Because this is a passive speaker element with no active electronics, there are no firmware, protocol, or network compatibility considerations. Correct impedance match and physical fit are the only two variables that matter.

Frequently Asked Questions

Q: Is the Q171230 a direct drop-in replacement for the Q170200?

A: Yes. Viking Electronics designates the Q171230 as the direct replacement for the Q170200. Same 2.5-inch square form factor, same 100-ohm impedance.

Q: What wire gauge are the leads on the Q171230?

A: The Q171230 ships with 26 AWG pre-attached wires.

Q: Will this speaker work in non-Viking intercom systems?

A: Possibly, if the system's amplifier output circuit is designed for a 100-ohm load and the physical cutout accommodates a 2.5-inch square speaker. Verify impedance requirements in your system's documentation before substituting.

Q: Is the Q171230 sold individually or in packs?

A: Based on available evidence, the Q171230 is a single-unit item priced individually.

Q: What Viking product lines is this speaker compatible with?

A: Viking's own store tags the Q171230 under the E-30-EWP entry-phone line. Confirm compatibility with other Viking units by checking the service manual for the original speaker impedance specification.

Karl Wilson

The Q171230 comes up almost exclusively in service and repair contexts — specifically when a Viking E-30-EWP or compatible entry-phone unit has a failed or damaged speaker. The 100-ohm impedance is the spec that matters most here. Viking's intercom amplifier stages are tuned to that load; drop in an 8-ohm speaker from a generic parts bin and you will overdrive the output transistor or get severely distorted audio at normal drive levels.

Technical Highlights:

• 100-Ohm Impedance: Matches Viking circuit design — prevents amplifier loading issues that would result from substituting a standard 8-ohm consumer speaker.
• 2.5-Inch Square Form Factor: Square profile seats directly in Viking enclosures cut for the Q170200; no physical modification required on replacement.
• 26 AWG Pre-Attached Leads: Eliminates field wire-gauge decisions; leads are ready to strip and terminate, reducing repair time on the bench or at the door station.

Deployment Considerations:

• Before ordering, confirm the unit's service manual lists a 100-ohm speaker — Viking uses different impedance values across product families, and ordering by form factor alone will not guarantee a correct match.
• The Q171230 is a passive component with no active electronics, so installation is purely mechanical and electrical — but take care with the 26 AWG leads, which are fine enough to nick or break during stripping if you use heavy wire strippers.

This part is the right call for service technicians maintaining Viking E-30-EWP door stations in multi-tenant residential or light commercial deployments where keeping installed Viking hardware operational is more cost-effective than full unit replacement.
