GR-Research works with a company that makes very high quality MDF flatpacks that need to be glued and finished. The Q of a speaker system is its resonance magnification, so a low Q speaker exerts more control than a high Q speaker. After (re) introducing the miniDSP 2×4, I’ll provide an overview of open-baffle speakers, and then proceed to the tutorial part – how to use the miniDSP as a 4-way crossover and equalizer. These are open baffle speakers with fairly high efficiency (~93db/w) with powered subs. The infinite baffle speaker is essentially a closed box and it the type that is used for most speaker systems. The infinite baffle is a closed and sealed box that aims to smother the rear sound waves from the loudspeaker. In this way there is no cancellation caused by the rear sound wave from the loudspeaker. Most tweed amps from the 50’s used either ¼ inch or 5/16 inch pine, which sounds open and loose. Lower distortion. Traditional speaker measurement of an open baffle speaker on a hoist in a field. Shaping the low-end (bass frequencies below 300Hz) is the reason for choosing a particular enclosure type.
