<\/a><\/p>\nIt has been a while since the last published loudspeaker design. The reason for that isn’t the lack of designs; it\u2019s the lack of time to publish them!<\/p>\n
The new Revelation Two \u2013 Monitor WG<\/a> loudspeaker uses one of my absolute favorite mid-woofers, the ScanSpeak 15W\/4531G00<\/a>. With its smooth frequency response it\u2019s very easy to work with and it sounds wonderful in shallow sloped cross-over designs.<\/p>\n This time I use a WG148R<\/a> waveguide from Visaton in combination with the Dayton Audio RS28F-4<\/a> tweeter and the ScanSpeak 15W\/4531G00<\/a> mid-woofer.<\/p>\n By using a waveguide it isn\u2019t necessary to use a stepped or sloped baffle to time align the drivers in order to compensate for the drivers \u201crelative acoustic center off-set\u201d. This is important when using a shallow sloped cross-over topology like the second-order Linkwitz-Riley type of cross-over used in this loudspeaker design.<\/p>\n The waveguide also have the benefit of improving the dispersion and to give a smoother power response compared to a conventional mid-woofer + dome tweeter setup.<\/p>\n There are three versions of the cross-over, the Simplistic<\/strong>, the Perfectionist<\/strong> and something in between, the Intermediate<\/strong>.<\/p>\n Each of them is a valid option and can be chosen according to personal taste and e.g. room placement. In my opinion each extra step to the Perfectionist<\/strong> cross-over adds additional sonic qualities, but for the cross-over purists the Simplistic<\/strong> version is nice.<\/p>\n
