Difuzoare rusesti OMO / LOMO

Recommended Posts

Topic pentru discutii despre boxele rusesti cu difuzoare Lomo.

Pareri, cu ce amplificatoare se potrivesc, etc.

 

Am luat mai demult o pereche de boxe OMO (model partial indescifrabil - typ 25A 78... ) cu difuzoare 4A32 V4 si un amplificator/mixer Vermona 1060 pentru curte/garaj.

Acum vreau sa trec la ceva mai fidel si ma gandeam totusi sa tin si lazile Lomo de back-up, sau chiar in paralel cu alte boxe.

 

Am desfacut o lada ca sa vad ce e inauntru, banuiam ca sunt difuzoarele care pe e-bay au niste preturi considerabile, si chiar ele au fost

Postez aici specificatiile gasite intr-un anunt, ca nu prea gasesc informatiile astea:

Citat

Si acum intrebarile:

1. Avand 15 Ohm, le pot lega la un amplificator mai normal? Am un Technics SA GX 280 (2x80W) si un Philips 594 (2x40W).

Philipsul leaga in serie boxele Front - Rear, daca le conectezi pe ambele...

 

Technics-ul zice ca accepta 16 Ohm in orice configuratie, impunand minim 8 Ohm per speaker daca legi A si B.

Doar la A sau B accepta si 4 Ohm.

 

La Vermona as renunta si as cauta alt amplificator pentru garaj.

 

 

2. De unde o fi buretele adunat in boxa. Banuiesc ca a fost lipit pe tot interiorul, cu exceptia panoului din fata, pe care e prins difuzorul.

Ma uit mai atent astazi. Cam obtureaza gaura pentru bass-reflex.

Ce as putea folosi ca sa refac capitonajul?
