Frequently asked.

Most listings can be purchased directly through our online catalogue. For new builds, dealer inquiries, or guidance on series selection, we recommend speaking with our team first — email info@adireaudio.com with your application and we'll route you to the right person.

Catalogue items typically ship within 1–3 business days from our California facility. Built-to-spec orders and custom configurations are quoted with a build schedule at the time of order.

Yes — we ship throughout the United States and accept international orders to Canada, Mexico, and select markets. International buyers are responsible for any import duties, taxes, or fees assessed by the destination country.

The Brahma is our reference subwoofer — the standard against which others are measured. The Koda excels in sealed enclosures and applications that prioritise musicality. The Tumult is engineered for home audio and infinite-baffle installations. The Brahma X is built for sustained high-output performance in vented enclosures. The Kali — the only 4-inch XBL² subwoofer in the world — handles essentially anything you ask of it. If you are unsure, our team will recommend a fit for your enclosure volume, amplifier, and listening preferences.

Every Adire product page lists the complete Thiele-Small parameter set — Fs, Qts, Vas, Xmax, Re, Le, Bl, and Mms — alongside published recommended enclosure volumes for both sealed and vented alignments. These are the same parameters we use internally to model the loudspeaker.

Each subwoofer ships with manufacturer-recommended sealed and vented volumes. Adhering to those recommendations produces the performance we engineered for. For unusual installation constraints, our team can quote an alternate alignment.

Yes — we maintain recone inventory for all current-production subwoofers, and we accept service requests for legacy products on a case-by-case basis. Contact info@adireaudio.com with your serial number and a description of the failure.

Yes. Every subwoofer page lists impedance options (D1, D2, D4) and recommended wiring configurations. Our wiring diagrams resource covers single, dual, and multi-sub installations across common amplifier configurations.

Each product page lists the RMS power rating for the driver. Match your amplifier to that RMS rating at the listed impedance — clean continuous output, not peak-rated.
