Blumenhofer Acoustics Fun 13 Walnut
The Fun 13 is the first loudspeaker, what we build on the concept of the Quarter Wave Length Horn.
The advantages of this construction are both in the compact form and in the deeper bass reproduction for the small driver.
The silk doom tweeter is a response to place and sound needs: the best balance to the sound level and finesse coming from this bass horn construction.
A true Blumenhofer entry level loudspeaker.

Specially the women and the visitors of the house pointed their eyes on the Fun 13
It is much more the contagious joy and lightness in the total sound impression
When Physic and Manufacturing come together, the listener has a lot to enjoy. - Article

Fun reflects the real nature of these speakers.
After the burn-in the low range was fine, absolutely unexpected for such a small speaker.
A very particular floorstander capable of surprising and amusing, and of giving a classy sound, unexpectedly big, rhythmical and deep if compared to its physical features. - Article

The tonal balance is nevertheless expertly set, coherent and more sonorous than bright.
The soundstage begins on the speaker line, i.e. is neither forward nor recessed and exhibits realistic dimensions.
Localization assignment is solid.
Instruments and particularly voices are pleasingly embodied.

I was astonished to find the presentation even more balanced as with my usual setup.
There was no preferred genre that the Fun 13 liked better than others.
It does not "stand in the way of music", and what else can one tell better on a loudspeaker in this price range.
