Use our data

What the data is

Our pipeline stores a first-class “unstated” wherever a spec sheet goes quiet, so we can count the silence rather than quietly dropping it (our methodology). The dataset published here is the aggregate of that counting, across all nine categories we track — receivers, loudspeakers, subwoofers, TVs, projectors, projection screens, media players, acoustic treatment and theater seating, 2547 products in total. For each of them: how many state a given specification, how many of those also state the measurement conditions that make the number mean anything, and — for the two categories where a single headline figure carries a companion condition — the same breakdown per brand. It is the summary layer behind the Spec-Sheet Honesty Report, recomputed hourly from the live catalog.

Three honest caveats travel with every figure. “Not stated” means our normalized record carries no value for the field — either the sources we track don’t state it, or no source we track covers it; we count our records, not manufacturers’ intent, and the pipeline’s refusal to guess is what makes the two line up. A stated no counts as stated: a projector sheet that says “VRR: not supported” has told you something, and only silence is silence. And a brand needs at least 3 tracked models before it gets a table row, because fewer than that cannot characterize a brand honestly — which is also why per-brand tables exist only for loudspeakers and receivers, where one headline number carries one companion condition. The other seven categories are published at category level rather than given an invented column.

Licence

That licence covers the counts, and only the counts. The per-product catalog — the individual specifications, provenance records and prices, including everything served by our catalog API at /api/catalog/<category> — is not CC-licensed and stays under our own terms: free for individual, non-bulk use with attribution and a link back; for bulk or commercial use, get in touch first. We’d rather say yes to a specific request than pretend a blanket grant covers data we normalize product by product.

Both halves of that split are mirrored in our Terms of Service, which carries an express carve-out for everything licensed here — the two pages state the same sentence from the same constant, so the site can never tell you one thing on this page and the opposite on that one.

Downloads

Both files carry the same aggregates, a generated-at timestamp and the licence, so a file that has been mailed around still says when it was cut and how to credit it.

How to cite

Quote a number with its date — the catalog grows, so a figure without an “as of” is a figure that will quietly go wrong. These blocks are generated from the numbers above, so they’re correct as of this page load. Paste one as-is:

If you need the wording adjusted for house style, or a figure for a category not shown here, ask — see below.

Press & data enquiries

For press, data or licensing questions, email support@hometheaterbuilds.com with “press” or “data” in the subject line and we’ll prioritise it.

Custom cuts are free and welcome. If the published aggregates don’t answer your question, tell us the cut you need — by brand, by category, or a combination — and we’ll run it against the live catalog and send it back as CSV or JSON under the same CC BY 4.0 terms. Corrections work the same way: every value traces to a source, so if a number looks wrong, send us the manufacturer page or manual and we’ll fix the record rather than the story.

Home Theater Builder is built and maintained by Aaroh Sharma, its founder. He writes the buying guides, builds the data pipeline that normalizes every spec sheet in the catalog, and maintains the compatibility engine that checks your builds. Every guide on this site is written against the same normalized data the builder uses — no claim appears in a guide that the catalog can’t back.
