Ikea spherical speakers, first build done.



Project was inspired by Cabasse and the curves employed in B&W 800 series, although on a much smaller budget. Had the idea to use bowls, Ikea had the wooden Blanda which seemed perfect. After scouring the net, found several others using these, although none using the 28cm versions. Design is an active 2 way design.

First completed photo (no tweeter), initially using Zero class T amps.

Current incarnation, using rotel 6 channel amp, channel for tweeter and mid, bridged for 15" sub, experimenting with solid oak sleeper stands and granite plinths.

Tweeters rather delicate positioning on top, seems to be fine without an enclosure, however I am experimenting with casting tapering tubes using champagne flutes.



The Sound: To my humble ears they sound rather good, haven't obtained a microphone to do testing. Definitely better than my Mission V63, which have an rrp of over £500. The 'no baffle' 15" add good low level sound reinforcement, as they don't go terrifically low or have very much bass



The drivers are Peerless M16GH (link below to drivers and excellent seller from eBay)





The tweeters are also Peerless metal domes, model unknown.



Currently crossed at 15" Sub 20-150Hz, Mid 50Hz-3Khz, tweeter 3Khz-20Khz



The sphere's come in at around 8L, (9.1L before cuts and driver displacement) One has eggfoam stuffing the other is naked will aquire some different materials for testing when I have a good mic.



They need another sand down, better integration with the stands and experiments with internal wadding, and the new tweeter housing, when time allows. I thought I should post pictures of my first build.Project was inspired by Cabasse and the curves employed in B&W 800 series, although on a much smaller budget.
