Fullrange Grundig

hi again everybody,
the project which l want to make ,doesnt accept 32ohm fullrange driver so l decided to built anew cabin for these 32 ohm grundig drivers,
is it possible to use these cabins with a normal solide state amp8 ohm
thank you for any response
eli

It will cause distortion on high power. But you can add an transformer in between to match the amp output impendance to the speaker impedance. A 1:4 transformer with a good bandwith for audio can do that, but it will cost money. But then also the amp has to have 4x the rated power of the speaker i thought.

Some basic info (altough for guitar amps, but the principle is the same for hifi):Ohm cooking 101: understanding amps, speakers and impedance - Hughes & Kettner BLOG
 
I don't suppose you would like to buy another pair of 32 ohm drivers, would you, Eli? 😉

I ask because a pair of 32 ohm drivers connected in parallel would give a more amplifier friendly load of 16 ohm.

However, you would need a second pair of 32 ohm drivers to make up the other stereo enclosure.
 
Nothing, as long as they form an appropriate load for the amplifier concerned.

32 ohm drivers are manufactured to facilitate series-parallel wiring in multiple driver systems such as pro audio line array and column array applications.
 
That would result in an impedance of 3.6 ohm, but the 4 ohm speaker would almost certainly play louder that the 32 ohm speaker since it will receive the greater share of the current.

I = V/R i.e. current = voltage divided by resistance. Since the voltage is the same across parallel speakers, the smaller the resistance, the larger the current through the speaker.

That's before we take the unknown relative sensitivities of the two drivers into consideration, but I would still never do as you suggest.

I perceive that you may be in need of revising your knowledge of Ohm's Law and voltage and current distribution in series and parallel circuits! 😉
 
i don't get why he can't just use them as a 32 ohm load, one per side.

it would be a greater consequence if he was running too low of an impedance.

some are just too fixated on the somewhat dubious concept of things needing to match...

He certainly can, if he can accept a drop in power.

I note vintageyear says his solid state amplifier is rated into 8 ohm. Since power is inversely proportional to impedance, a 32 ohm load will receive only 25% of the power that an 8 ohm load would.

Even less power will be available at bass and high frequencies where the impedance will rise substantially above the nominal 32 ohms.

However, provided vintageyear's amplifier has a sufficient reserve of power, it is OK, and quite safe, to run a single 32 ohm driver on each stereo channel.

P.S. I, too, don't understand why that would cause distortion at high power as waxx has suggested.
 
With most decent amls driving 32 Ω will have less power (about 1/4th the 8Ω rating) but distortion should be lower and there will be much less stress on the PS.

This is the kind of impedance where a high V PS chipamp might work really well.

Impedance also makes them suitable for OTL amps, and maybe even some of the high power headphone amps.
