I built a small (4 liter) ocateder shaped pair of loudspeakers with the FR125 for my daughter (11 years old).
The cabinets are aperiodically damped, I used a small BR pipe and filled it tight with BAF.
After first listning I decided that a notch filter would improve the sound
R=4.7ohm, L=0.56mH, C=22uF resulted in a nice flat response.
and the sound: wel simply very good! the high end is excelent for a 4" FR, but bundling is a lot more that e.g. a 3" Tangband. the low end, despite having a f3 of ~100Hz, is still tjhat of a larger box.
all in all I am rather pleased with the result (although the paint job could have been better) |

Lovely build... i love it when something other than a rectangular box shows up (i know i'm guilty of that)...

Thanks for the compliments.
best of both worlds, this shape is both artistic and techy :D
I wonder when my daughter starts getting tired of her dad continiously coming in and playing CDs on her set :rolleyes: yes, I am very pleased about the result, and so is Sofia. here´s one happy father |

As you can imagine, I've read the previous thread. When I asked how they sounded, I wanted to know if they sounded boomy, tight, how the bass was? See, I wanted a detailed analysis.
"Simply good" is not enough. |

than you have to built them yourself and hear for yourself :)
even detailed analysis is somebody else's opinion
individual opinions vary |

and besides that, I'm not very good in highendish ;) but I'll give it a try then
bass is "just right", absolutely not boomy, but certainly present (as in not absent). of course the lowest octave is not there, and big drums are softer than usual.
high is nicely detailed without any sharpness. off axis it gets softer, bundling is of course an issue with this size FR
tonal balance is (with the notch filter) excelent, instruments and voices sound very natural.
and the soundstage, well it's a fullranger, it does what you expect it to do... only the best multiway speakers can come close to this. |

That is what I wanted to hear. Thanks!
They seem to sound pretty good, then. |

Nice job!
Just curious if you managed to snap any pics of the build process?
Really cool looking, like planet 10 said its nice to see something other than a rectangular box. |

:ashamed: we were so busy builbing that we forgot to take pictures... but the general process was we laid the 8 triangles on the floor (the side which is to become the outside on the floor), used tape to stick them together, then applied the glue and closed the box, the tape acting as glueclamp. the hole for the driver was routed afterwards, as we wanted to pick the best looking side as front.
key to success with this form this is acurate sawing, very accurate sawing.... |
