8 ohm vs 4 ohm

I just bought the Wavac 833 v1.3 amps and I need some help pairing them with speakers. There is a local dealer with the MBL 101e but he told me they need/take a 4 ohm load. I really know the difference between 8 ohm and 4 ohm. I have seen speakers requiring 6 ohm! Any help out there?

Re: 8 ohm vs 4 ohm

Wow! Congratulations.

The amp will work with just about any speaker, regardless of the impedence. The Wavac has outputs for either a 4 or 8 ohm load. This doesn't mean it won't work fine with a 6 ohm load or anything between.

Speaker impedence ratings are somewhat misleading without knowing the full impedence response at various frequencies. Dynaudio, for example, will list a speaker as a 4 ohm impedence, though it may never dip below 5 ohms and might spend most of its life above 8 ohms. Another manufacturer might list a speaker as 8 ohms even though they dip to 4 ohms and stay there for much of the frequency band.

In any event, I wouldn't be too concerned about the ohm rating of the speaker you would consider. The sensitivity would only be a concern with that amp if you like to listen at loud levels in a large room. If that is the case, you might want to consider a speaker that has a relatively high sensitivity...say 88db at a minimum and 94 or so if you want to go loud.

If you are after the best sound at relatively sane volume levels, your choices are limitless with that amp.

Let us know what you end up liking or buying.

Listen to these while you shop for your final choice:

Insignia NS-B2111

They should mate well with the Wavacs and not hurt your speaker budget too much while you look around.

Excellent! Do you suppose the guys at Best Buy can help explain this 4 Ohm/8 Ohm thing?
