Its Peter from @diyfullrangehifispeakers Here is the build of the Visaton FR8 that I bought from Element14. I'm really impressed with the sound actually. Early days yet and they're still burning in. Please ask questions or leave feedback. BTW the design is based on a Cheap Trick 193 with a longer port as was modelled for the SB Acoustics in WinISD. I should have mofelled the Visaton in WinISD too but I find these aren't too sensitive to port length anyway. In a week or two Ill have two speakers waxed and I'll post a proper sound check. Many thanks to the Licensors or SRV music for allowing the use of Tin Pan Alley for the soumd test. These small speakers do blues very well. ☮️👍🌈
