Possession of the Visaton W200S woofer now for 15 years. Before they were installed as rear shelves speaker with two domes and Visaton Visaton DT94 two-way switch in my old car, then at my nephew in his car, now they make in my column speakers in service. There they were exchanged for each one of the original woofers. This really only time to test. But, there are times you stay beautiful. The boxes have an unprecedented depth, the precision bass was increased enormously. Sonically an absolute enrichment. And only the previous life, as I said, 15 years, testifies to the absolute quality. And they had both in my vehicle and where my nephew cope fairly high level and often were the musical entertainment meet with sometimes similar used. So if you have to replace speakers or want should look past times when Visaton. There are certainly more favorable price, but at the Visaton price - performance ratio was absolutely in order. Anyone who wants to should sometimes look at the kits by Visaton. My bookshelf speakers are built by then. Sonically convincing than most venal here models from different manufacturers. Handdwerkliches skill and good tools are of course a prerequisite. For bargain hunters: Visaton also has a favorable W Series.
