Udo Wohlgemuth designed a loudspeaker called Inside Out, with hidden Monacor SPH 135 TC band pass.
Sound review by Klang+Ton 2/2006:
..."Since Yello's "Baby" was still in our CD player, we decided
to play "Blender", not necessarily food for thought, but a fare
that might be swallowed the wrong way by some show-off speakers. After burbling
along for a while, especially with uncritical mids and tops, the first two
bass kicks hit our stomach. We thought we had fallen for an acoustic illusion.
One of our colleagues who happened to enter the listening room, asked us whether
we have listened to these small speakers without the subwoofer. Well, his
search for bass support was to no avail. "Sultans of Swing" by Dire
Straits was reproduced by these manikins as if the music was coming from monsters.
Electric bass, vocals, guitar runs and cymbal crashes came up without any
critical sounds, neither from the speakers nor from the listeners. It wasn't
any different when Mick Fleetwood battered his bass drum on "I'm So Afraid.
Afterwards, we were spoiled by Lindsey Buckingham's acoustic guitar and Stevie
Nick's delightful and captivating voice on "Landslide". But, even
Shakira, Melanie C, Scooter and Fettes Brot were given the right treatment."
