Hello, I'm not really too well versed in Audio, so im sorry if this question may seem a bit silly to you experts.

A few Months ago, I got my self some Vintage 4 Way Speaker Boxes from the late East germany. The person I bought it from, insisted that these need very specific Amplifiers so all 4 Speakers of the 4 Way System will be utilized.

The Amplifier he said worked best with that are Fera V150s, also Vintage east German stuff... issue here being that mine has issues working consistently, so I'll probably have to replace it at some point.

What seems odd to me is that the 4 way Speaker Boxes need specific Amplifiers to use all 4 Speakers? Is that true, or would any amplifier be able to drive all 4 Speakers just fine?
