Am confused concerning the quality and type of tweeters in both the Encore and Ulfberht. The DIs have sbacoustics SB29RDNC ring dome radiators; have purchased spares of these from Madisound and they are $57.20.
The ScanSpeak drivers in the Ulfberhts appear (by sight) to be ScanSpeak D2605 dome tweeters (either the regular dome or the limited edition textile dome) that Madisound sells for $48.60 and $54.40. If so, wonder about any improvement in quality here. Personally, I would prefer a ring dome radiator over a dome as it might have less mass -- as Eric touts. It is true that the ScanSpeak drivers reach down to a lower frequency.
But you or Eric's people can let us know the actual specifics..
