Every driver is published with its complete Thiele/Small parameter set, frequency-response and impedance measurements, a datasheet PDF, a 2D drawing and a 3D STEP model, so a system designer can simulate a cabinet before ordering a sample. 8 of the drivers have been independently measured and reviewed by audioXpress / Voice Coil and other publications.
Catalog specifications at a glance
Key figures for every model in this category. AES power is the two-hour AES2-1984 rating; programme power is twice and peak four times that figure. Complete Thiele/Small data, drawings and CAD are on each product page.

How to choose professional loudspeaker drivers
Start from the application, not the driver
A two-way PA top, a subwoofer, a column, a stage monitor and a ceiling speaker each want a different balance of sensitivity, excursion and bandwidth. The category pages below group the catalog the way a system designer thinks about it.
Match size and power to the box
Nominal diameter sets cone area (Sd), and with Xmax it sets how much air a driver can move. The AES power rating on every REDCATT datasheet is the two-hour AES2-1984 figure; programme power is twice that and peak four times.
Use the T/S data, not the marketing
Fs, Qts and Vas determine whether a driver belongs in a vented, sealed or horn-loaded enclosure. All three are published for every low-frequency driver and can be pulled straight into a simulator.
Neodymium or ferrite
Neodymium motors cut weight by roughly half for the same flux, which matters for flown line-array elements and portable systems. Ferrite motors cost less and are unaffected by rare-earth price swings, which matters for high-volume installed-sound and OEM products.
Typical applications
- Two-way and three-way PA loudspeakers
- Subwoofers for touring, club and cinema use
- Line-array elements and column loudspeakers
- Stage monitors and portable powered speakers
- Installed and commercial sound systems
- OEM and ODM loudspeaker programmes
Engineering data for every model
Full Thiele/Small parameters, frequency-response and impedance plots, datasheet PDF, 2D drawing and 3D STEP model on each product page, and the same data as JSON from the product API.
Independently tested professional loudspeaker drivers
8 of the 111 drivers on this page have been measured or reviewed by independent publications. Metadata and links only; REDCATT does not publish ratings it did not earn. See all coverage on the reviews page.
Custom professional loudspeaker drivers for OEM and ODM programmes
Every driver on this page can be adapted for an OEM programme at REDCATT's own factory in Dongguan: impedance, voice coil, cone or diaphragm, surround, motor and frame changes, or a new design built to a target specification. Standard catalog drivers have a minimum order quantity of 1 piece; custom and OEM MOQs are flexible, starting at 100 pieces, with quantity-tiered pricing; production lead time is 45 calendar days.
Tooling and NRE apply to custom developments that need dedicated tools. The range is wide: simple tools can cost as little as a few tens of dollars, while complex injection tools can exceed $50,000. NRE charges are refunded against placed production orders.
Quality and warranty
- - ISO 9001:2015 and IATF 16949:2016 certified quality system.
- - Every unit measured end-of-line; see the production consistency report.
- - Three-year limited warranty.
Professional loudspeaker driver questions
What kinds of professional loudspeaker drivers does REDCATT make?
REDCATT manufactures low-frequency drivers (subwoofers, woofers and mid-woofers from 8 to 21 inches), high-frequency drivers (compression drivers from 1-inch to 1.8-inch exit and dome tweeters), full-range drivers and coaxial drivers. All 111 catalog models are listed on this page.
Are the drivers sold individually or only to OEM customers?
Both. Standard catalog drivers are available to system builders and integrators with a minimum order quantity of 1 piece; OEM and custom developments are handled separately with an MOQ that is flexible, starting at 100 pieces, with quantity-tiered pricing.
What engineering data is published?
Every driver page carries the full Thiele/Small parameter set, sensitivity, power handling, voice-coil and magnet details, physical dimensions, a frequency-response and impedance plot, a datasheet PDF, a 2D drawing and a 3D STEP model. The same data is available as JSON from the product API.
What is the warranty on REDCATT drivers?
REDCATT drivers carry a three-year limited warranty; the full terms, conditions of use and claim procedure are published on the warranty page.
