Testing out loud (speakers)
#1
Hello Folks!

Last week i had a little bit of time to made some testing with speakers.
And a word before, here i can only describe my own (and subjective) impressions of sound.

The candidates.

Right side from above:
- conventional 28mm speaker with PP-membrane in Soundtraxx baffle kit
- 28 x 28mm High Bass 2W speaker with metal membrane
- 30 x 40mm speaker witn conventional membrane
All have an impedance of 8 Ohm

In the middle one of those astoning tiny sugar cubes Reinhard told me of.

Left side from above; alle were sugar cubes of the Knowles Dumbo 1W; 8 Ohm type, but in different enclosures from Zimo:
- 13 x 18 x 13mm
- 40 x 20 x 9mm
- 40 x 22 x 9mm; two Dumbos wired in serial; 16 Ohm
- 50 x 15 x 14mm; in effect intended for G-Scale; 16 Ohm

Alle speakers were equipped with wires and plugs, so that a quick change of the speakers is possible. The speakers without baffles or boxes got a special "hand" created baffle.




The stage.

Decoder tester from Zimo, here for all tests a Soundtraxx Econami ECO-100 Steam sound decoder was plugged to get equal preconditions. The sound volume was turned down to low volume and the adjustments were for all tests the same.
It is not my intention to make loud noise or simply a certain level of noise, but to get a certain quality of sound without a tympanum (eardrum) perforation. :hey:
The stage is set, the candidates are prepared and in near future i will narrate my impressions.

Cheers Lutz
