SES RPSPEAKER1 , SPEAKER 8 OHM, 2-5/8" DIA W 3-1/2" ADAPTER W/SILICONE, CAT/SG/TECs (*2)
The SES RPSPEAKER1 is an 8 ohm replacement speaker assembly listed with a 3-1/2 inch adapter and silicone for compatible CAT, SG, and TEC entry units. It is used where the speaker service part needs the adapter setup rather than the smaller gasket-only format.
This speaker should be selected by the installed panel layout and original speaker assembly. Similar SES speakers can look close in a parts list, but impedance, mounting opening, adapter ring, sealant style, and unit family matter. If the entry station audio is intermittent, also inspect the microphone, wiring, board terminals, moisture damage, and phone-line condition before assuming the speaker is the only failed item.

Technician Note
This is the adapter-style 8 ohm speaker listing. Use it where the panel originally uses the 3-1/2 inch adapter setup, not just because the unit is a CAT, SG, or TEC.
Before Ordering
- Confirm CAT, SG, or TEC unit family.
- Match the original 8 ohm speaker requirement.
- Check whether the existing assembly uses the 3-1/2 inch adapter.
- Do not substitute with RPSPEAKER1N unless the gasket-only layout matches.
- Inspect water intrusion and speaker wiring before replacement.
Professional Advisory
If a speaker has failed because of water or corrosion, inspect the enclosure seal and drainage path before installing the replacement speaker.
Product Questions & Answers
What does the RPSPEAKER1 include?
The uploaded listing identifies it as an 8 ohm speaker with a 3-1/2 inch adapter and silicone for CAT/SG/TEC applications.
Is RPSPEAKER1 the same as RPSPEAKER1N?
No. RPSPEAKER1 is the adapter-style version, while RPSPEAKER1N is the 2-5/8 inch gasket version.
Can I use it on SAT units?
No. SAT units commonly use the 25 ohm RPSPEAKER2 speaker.
What should I check if the speaker sounds distorted?
Check speaker condition, water damage, wiring, amplifier/audio board condition, and telephone line quality.
Why does the adapter matter?
The adapter affects mounting and sealing. A speaker that is electrically correct may still not fit or seal correctly without the proper adapter style.
