Mounting depth

The mounting depth of car audio is, in fact, the size of the speaker in depth. Note that for component sets (see "Type") this parameter is given for the largest speaker, and for case models it is generally irrelevant.

The mounting depth, along with the diameter of the speaker (see above), determines the amount of space needed to mount the speaker — in this case, how deep a niche would be required for normal mounting. At the same time, the larger the speaker, the larger, usually, the installation depth. And with similar diameters of equal size, a more powerful model is likely to be more “deep”.

The smallest amount of space — up to 15 mm deep — is required by some tweeters. A depth of 16 – 30mm is normal for tweeters and very shallow for general range speakers, most of these models have a depth of 30mm or more. At the same time, full-range speakers are usually "recessed" by less than 60 mm, component systems — by less than 90 mm, and more depth may be required only for some coaxial and mid-range models and, oddly enough, tweeters.
