How Bits sources, checks
and publishes driver data.

Manufacturer product pages and datasheets are the primary source for models, dimensions and acoustic specifications. UK-facing vendor pages provide price, stock and purchase-link signals. Driver pages retain the manufacturer source or datasheet link where available, while vendor offers link back to the seller.

Source labels are converted into consistent units and canonical field names. Vendor listings are matched using manufacturer, model and impedance evidence; ambiguous variants and bundles are excluded from exact price comparisons. A normalized value is an interpretation of the cited source, not a new measurement.

For low-frequency drivers, automated checks cover required Thiele–Small fields, physical ranges and relationships between values. Valid means the available record passes those checks. Warning flags missing or questionable evidence; Error flags a stronger contradiction;Unchecked means the validator has not produced a result. These labels do not certify a product or replace measurement and engineering judgement.

Prices are comparison signals captured from seller listings in the UK, the EU and the US, and normalized to GBP before conversion to the currency you choose. Best prices follow the country you ship to, which comes from your location until you change it in the price display menu. Only shops that deliver there through their normal checkout count, and those delivering from inside your VAT area come first; a best price from abroad says where it ships from, because import VAT and duty may apply. Shops that need a quote, say they do not deliver there, or do not say, stay listed under the other offers but do not set the best price. Where each shop delivers is read from its own shipping and terms pages and re-checked over time. The interface states whether VAT is included or excluded where that evidence is known. When at least three like-for-like current offers are available, conservative relative-price checks can mark an isolated value as unusual. That offer stays visible and linked, but is left out of best-price, average and alert calculations until its peers no longer support the warning. A below-average figure needs offers from at least three sellers after those checks; with two, it would only say which seller is cheaper. Stock, delivery charges, promotions and tax treatment can change between refreshes; confirm the final price and availability with the seller before buying. Some outbound links may become affiliate links, but that does not change validation or matching rules.

Some driver pages list independent test benches, measurements and forum discussions of that driver. Each is named by its publication and article title, or its forum and thread title, never by a person, and links to the source, which owns it. Summaries are Bits' own words and say only what the source's text says; a quote is one short verbatim phrase at most, and graphs and tables are never copied. A figure a source measured appears beside the published figure only when the source compared it with that same value. The list is chosen by hand, so a driver without sources is not a verdict on it. Some shops also publish their customers' ratings for the drivers they sell. Bits reads those figures when it refreshes a shop's prices and shows them as published, each with its shop, how many ratings it rests on and when it was last checked. Bits does not collect, select or verify ratings, and shops count and moderate them in their own ways. A driver's overall figure weights each shop by its number of ratings. One page per shop counts, and only like-for-like offers still on sale. A rating that has not been re-checked for 14 days is no longer shown. Shop-wide scores that appear on every product are ignored. Neither reviews nor ratings are added to the page's search-engine markup.

A driver's Designs section brings together cabinets published for it. Makers' designs and suggested boxes come from the makers' own sites (B&C and Eighteen Sound so far) and link to their plans. A design shows on a driver's page when its plans name that model, on each of its impedance versions, and on the revision that replaced a model the plans name; the page says when the plans name another version. Plans published by builders are a reviewed list of links, each saying how the plans name the driver. Flatpack kits appear beside the design they are cut to, one row per kit maker, cheapest first; 00 Audio, which makes Bits, is one of them, and other kit makers can ask to be listed. Every design is also listed on the designs page by the size of driver it takes, and each model with a maker design, builders' plans or a kit has a designs page of its own; a suggested box alone doesn't make one. Bits has not built or measured these designs. When a maker states a box fully, with its volume and tuning, 00 Simulator models it from the published T/S values and sizes a port for the driver if the maker gives none; those figures are estimates, not measurements.

Manufacturers publish data in inconsistent formats, model families can contain near-identical impedance variants, and pages change without notice. Automated extraction can therefore be incomplete or wrong. Use the report control on each driver page, or email support@00aud.io, with a source for the correction. Reports are reviewed against manufacturer or seller evidence before catalogue data is changed.
