I'd say there is something near mystical about the little L300s. The localization of the left and right channel is phenomenal in a speaker of this size, then you add the clarity of the same tweeter used through the line and the fast 5.5" woofer. The Minimus 7 isn't even in the same league, despite what you can read here about the comparison. -sf
The L200/L300 tweeter uses a smaller magnet than the one used in the larger speaker. The efficiency is lower. Here is a breakdown of tweeters -
206-0101 - Used on early 200/300 series. It has a sticky outer coating.
206-0101A - Used on later models. Sticky coating is on inside of dome & the parts can be used interchangeably. The "A" stood for automotive. Models that use this 1" dome tweeter are as follows:
L10, 200, L200, L200c, L200cc, Delta Lab M1, 200i car speaker
300, L300, L300c, L300cc, 300i car speaker
206-0126 - Used in the later versions of some of the above speakers. It has a shiny black plastic dome. A little less efficient than the doped fabric dome but with better detail.
L200e, L300e, 200is, 300is
The 206-0126 can be used interchangeably with any of the 0101 versions but a minor crossover change depending on the model may be needed. Some of them had a series pad on the tweeter & it should be reduced in value.
For any of the above, you'll find the front plate of the tweeter with & without the stamped ADS logo.
Large bookshelf speakers also used a 1" dome tweeter but with a bigger magnet. The earliest versions often had a set of hotdog shaped holes surrounding the tweeter.
206-0100 was later replaced by the 206-0116. They are interchangeable.
The 3-way bookshelves & small towers used a 3/4" dome of identical construction to the above.
206-0107 was replaced by 206-0117. They are interchangeable.
The largest bookshelf (L980) & large tower (L1590) used a 3/4" with larger magnet than any of them. It was the 206-0118 and it has no equivalent.
The L2030 (& maybe the L1530) used the 206-0119. A 1" with samarium cobalt tweeter. Wilson Audio used these in an early version of the WAMM.
For any of the above, you'll find the front plate of the tweeter with & without the stamped ADS logo.
Around 1988, all new models started using the copolymer tweeters. No 3/4" version was made, only a 1". There were essentially 4 versions.
206-0122 rectangular plate (fits earlier rectangular plate routed openings but the plate is thicker.
206-0123 round plate. Identical to the 0122 except for the plate.
206-124 round plate. Same plate as the 0123 but with larger magnet.
206-128 round plate. Identical in size to the 0124 but front plate is billet aluminum. Perhaps the finest tweeter ADS ever made.
