Default Recomandare boxe

Salut,

As vrea sa inlocuiesc boxele din actualul sistem audio cu niste boxe ceva mai bune si sa pastrez doar subwooferul.

Sistemul actual Microlab M-910.

Link : http://www.microlab.com/?r=21systemen&st=full&id=646

Power distribution 10x2 +25, Watt
Harmonic distortion 0.3, % (1Watt, 1kHz)
Frequency response 50-20 000, Hz
Signal/Noise ratio 75, dB
Separation 40, dB
Speakers specs
Tweeter driver type 1+3 ,
Bass driver type 6.5,

M-am gandit ca as putea sa le inlocuiesc cu niste boxe Magnat Supreme 102 insa nu stiu daca se potrivesc. Nu ma pricep deloc.

Tu vrei sa pui boxa de 55w in locu la 10w si te astepti sa mearga?

Risti sa arzi amplificatorul din acele microlab, boxele alea de raft vor trage mai multa putere decat niste sateliti. Sau in cel mai bun caz se vor auzi mediocru.

Fie cumperi alti sateliti, gen https://www.avstore.ro/boxe/cambridg...o-minx-min-12/
Fie schimbi tot si mergi pe amp+boxe. Depinde de buget.

Poti sa cuplezi ce vrei tu dar boxele alea sunt prea mari pentru amplificator, conteaza mult si impedanta lor etc etc.

Prin simplu fapt ca vrei doar sa schimbi niste boxe cu putere mai mare pe acelasi aplificator nu inseamna ca se vor auzi mai tare si ca e oke.

Cel mai bun combo e sa vinzi ce ai acum si sa iei altceva mai bun.

Nici nu risti sa arzi ampliful, nici nu vor "trage" mai multa putere. Boxele consuma cat le dai. Daca ampliful tau le da 10W, 10W o sa consume. Poti sa pui boxe de 10000000W pe amplif de 10W si n-o sa se arda nimic (decat daca au impedanta mult mai mica. adica ampliful suporta 8Ohm si tu pui boxe de 2 ohm).

Le iei dar investesti degeaba, ca sa le folosesti la potential maxim ai nevoie de alta amplificare.

Daca vrei sa se auda mai tare pe aceeasi amplificare, iei boxe cu decibeli mai multi. Fiecare 3db in plus reprezinta o dublare a puterii. Adica daca boxele tale au acum 90db si asculti cu ele la 10W, niste boxe de 93db o sa se auda pe aia 10W ca ale tale la 20W dpdv al volumului. La fel, 10db reprezinta de 10 ori mai multa putere. Un difuzor de 97db o sa se auda la 10W la fel de tare ca un difuzor de 87db la 100W.

Bine, mai conteaza si claritatea in ecuatiile astea, ca poti sa iei boxe care urla dar se aud ca un rahat.

Nici faptul ca se vor "auzi mediocru" nu-ti dai seama din putere. Eu acum stau cu Unitra 75W + Heco Victa 301 puse in paralel pe un amplif de-asta Lepai LP-2020A+(s-a ars kenwood-ul de 13kg si 2x100W RMS acum cativa ani si nici n-am binevoit sa-l repar). In review cu scule ca lumea a iesit ca da... 7W RMS pe canal pana intra in clipping. Nu ascult aproape niciodata la maxim de "obraz" sa nu deranjez vecinii.

Asa ca... daca vrei crestere de calitate poti face upgrade la boxe si sa pastrezi ampliful. Pe viitor poti pastra boxele, vinde sistemul si cumpara un amplif separat daca vrei inca un "boost".

Poti sa pui orice fel de boxe, si de 1000W pe orice amplificator de putere mai mica decit a boxelor (si chiar mai mare pentru ca o boxa suporta 2x RMS power, adica program power).

NUMAI sa respecti impedanta minim recomandata a amplificatorului, 8-6-4 ohmi.

Adica daca ampliful suporta boxe de 4-8 ohmi, boxele pe care le pui NU trebuie sa aibe mai putin de 4 ohmi.

Cum zic băieții mai sus, boxe cu sensibilitate mare 90 sau 92 db.

Însă cumpăra niste scule mai serioase, boxa fiind 50-60% din sunetul final ( in digital).
