Suggestions for Speakers for use with Helder TA2020 MKIII
 

I want to put something reasonable into a 30ft sailing boat.
I have limited room for speakers and limited power to run them so I am thinking of using TA2020 MK111 that I got a while ago and it is still sitting around. I can link this to an 500GB Archos with all my music in FLAC
I currently use Audio Nirvana 15" full range with a KT66 tube amp and I love them.
I would like to stay with single drivers but do not have room for big boxes.
I have seen the Tang Brand 1808 mentioned for use in open baffle but I think I would defiantly need to supplement the bass, which will mean another amp and more current draw.
I have always thought there to be something magical about open baffle.
Most of my listening is relaxed Jazz, Instrumental, and Female Vocalist.
I would appreciate any suggestions as long as it doesn't mean boxes any bigger than about 8L Max.:eek:
