Fysisk små bilforsterkere

[Miniboom]

Vet at det har vært spurt etter dette tidligere, men tenkte det hadde vært fint om vi kunne listet opp fysisk små forsterkere som man kunne montert i dashbord, under setet, etc. Det er jo nesten et must om man vil ha korte kabler og/eller mer plass i bagasjerommet.

Uten å ta hensyn til lydkvalitet (eller mangel på sådan), kan jeg liste opp et par små:

- Output 4x60W at low distortion, 4x100W peak

Hvordan er lyden fra denne, noen som vet? "Klasse T", eller?

Bare lurer på om den egner seg for noe annet enn >100hz, eller veldig lavt volum, siden jeg ikke helt ser potensialet for noe særlig strømgjennomgang her. :P

[epifant]

Vet ikke hvordan de låter nei. MEN to AMP9 kan visstnok paralellkobles til 2x120w, og da begynner det jo å likne på noe.

Rettet forresten posten min ettersom man kan bruke den minste AMP32-versjonen. Den store "glattelytten" trengs ikke ved likestrøm har jeg lest.

[r3mark]

10% distortion er jo hyggelige tall å jobbe med ;P
