 <\/p>\n

Every designer has a “philosophy” regarding on how to build the best possible loudspeaker. My “philosophy”\u00a0 is “keep it simple” and “less is more”. To me, designing a loudspeaker is like cooking a fancy dinner. Use high quality ingredients in a well thoughtful composed combination, but don’t over do it. Let the fine ingredients speak for them self.<\/p>\n

The same thing goes for designing cross-overs. Don’t do it more complicated than necessary to achieve the desired goal. Keep the number of cross-over components to a minimum. If you can use a tweeter in a design without a resistor in series with it — “do it”. It will sound better. It’s not necessary to flatten out every little wrinkle in the frequency response by adding more cross-over components — “it will kill the sound”. Instead look back and see if you have chosen the right driver unit for the design.<\/p>\n

Other important factors for a successful design is to achieve an even power response and off-axis dispersion as well as a satisfying distortion behavior for the loudspeaker. If you follow these design rules, you will get rewarded with a wider, higher and deeper sound stage and the “sweet spot” will be bigger and you can play stronger before distortion becomes an issue.<\/p>\n

Again, this is my personal opinion and design “philosophy” and I’m aware that every designer has their own personal preferences on how a high quality loudspeaker are built.<\/p>\n

Loudspeaker Driver Units:<\/strong><\/h3>\n

 <\/p>\n

The choice of driver units for a design is an important factor for a successfully implemented design. Audioexcite<\/strong> will not use the cheapest or “buy-out” driver units available on the market. The drivers chosen here are from the mid to high price range, but that doesn’t rule out for instance a combination of a mid priced tweeter paired with a high priced mid-woofer as long as the performance of the driver is adequate. The driver units here are carefully chosen from a variety of loudspeaker driver manufacturers. I think the “heart” and “soul” of music lives in the mid-range, therefore the drivers chosen for the mid-range reproduction are critical for the end result.<\/p>\n

Cross-over Components:<\/strong><\/h3>\n

 <\/p>\n

 <\/p>\n

\"\"<\/a>I can say it right away! I’m not a big fan of super expensive cross-over components. In all of the AudioExcite<\/strong> loudspeakers I use cross-over caps and resistors from Mundorf. I have chosen the “Mcap Audiophile” MKP cap as the standard cap in all of the loudspeaker models. This is a high quality cap with a nice price\/performance value. It has very neutral character with a specified tolerance of +-3%, but often surpasses that and in real measurements +-1-2% is common.<\/p>\n

 <\/p>\n

 <\/p>\n

Mundorf<\/a> describes the Mcap Audiophile cap as follows:<\/p>\n

“The practically induction-free type of construction<\/em>
\nand the low loss factor of the MCap\u00ae results in a<\/em>
\nvery \u201equick\u201c capacitor.<\/em>
\nThe MCap\u00ae forms the basis for vivid music reproduction<\/em>
\nrich in nuance.”<\/em><\/p>\n

\"\"<\/a>In some designs where it’s justified, the Mcap Supreme is used for the tweeter series section of the cross-over. This cap gives a bit more refinement in the upper frequencies and the higher price tag is motivated by the additional performance improvement.<\/p>\n

Mundorf<\/a> describes the Mcap Supreme cap as follows:<\/p>\n

“Its subtle fine gradation of the high tone<\/em>
\nrange invigorates the entire sound production;<\/em>
\nvoices and instruments take shape and<\/em>
\nbecome extremely diverse.”<\/em><\/p>\n

 <\/p>\n

\"\"<\/a>All of the AudioExcite<\/strong> loudspeaker models uses air-core coils as standard. Where the price\/performance is motivated, foil coils are used in the mid-range series section of the cross-over. Where very large coils are needed, iron-core coils are used.<\/p>\n

Mundorf<\/a> describes the foil coils as follows:<\/p>\n

“With their excellent electrical and mechanical<\/em>
\nproperties, the foil coils aid in the<\/em>
\nreproduction of music, making it clearly more<\/em>
\ndynamic and faithful to detail overall.”<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"
