New "bedside" setup is almost complete, i replaced my Fostex fullranges with a DIY project based on the Seas U18Rnx and the Fountek NeoCD 3.0 ribbon tweeters.
It's a biamped setup with active crossover, an LM1876 gainclone for the woofers and a Ta-2024 dedicated to the ribbons
I've also built the fourth order Linkwitz-Riley filter myself; Crossover frequency is now set at around 3kHz , but socket mount resistors and trimmers to individually adjust each of the four outputs allow for maximum flexibility, and i'm experimenting a bit to find the optimal balance.
The cabinets are 20L bottom ported, made of 19mm MDF, it's a rather uncommon solution for a bookshelf, but i wanted to experiment something completely different. The final finish is still to be decided, but they don't look bad even in plain MDF
How do they sound ? I've never heard any high end system, but to me they are absolutely spectacular, the bass is extremely fast and well controlled, and the Fountek ribbons really deliver an airy and detailed presentation, without a hint of harshness.
