Using AR-1W's in 8 ohm mode?

Based on pics in the library that I think were of one of Tom's early AR-1W's, I surmise that the 1W can be operated in 8 ohm mode if the speaker placement is "unfavorable", or as I believe they say up against a wall or out in the middle of the floor.

I just wondered what one would lose sonically by so doing. Would the speaker just not be as loud as it would be at 4 ohms, would there be some kind of sonic degradation or what should be expected? I haven't given up on the idea of using these as a "sub" of sorts with 4x's and 2ax's, and if both pairs were running at 8 ohms it sure would simplify the hookup, or at least would minimize heating of the amp.

By the way, if the 1-2 terminal strap is missing, will just a piece of bare solid copper wire do just as well?

Many thanks,

Ed

Hi Ed

Using the AR-1W with these speakers would be excellent.

If you are talking about a single AR-1W speaker, then you use a combined signal to a separate amp with a volume control and electronic crossover so that the woofer would be controllable in level and perhaps a 50 - 75hz crossover.

If you just add the AR-1W in a series/parallel arrangement the balance will be way off.

The AR-1W would overpower the other 2 speakers up to maybe 1000hz without the crossover.

Way back, I hankered for a AR-1X when I first had AR-4X's, thinking of a center channel fill.

I thought that this would give me the terrific bass and the clear 4X's highs.

I never persued that thought, thank goodness, I would have found out quickly about that setup being incompatible and I could not have upgraded at the time financialy.

My AR literature regarding the AR-1 and 1W is buried at this time, so I won't guess at the jumper question at this time.

The Audio Amateur had a drawing years ago, of a pair of AR-3a and a center fill AR-5, or visa versa, my point is, they used a special transformer in that circuit. There was no volume adjustment as I remember. The AR-3A's would have not been overpowered by the single AR-5.

More help is on the way from other readers as they see your write-up.

Good luck, Ed.

Please keep us informed as to your progress.

The AR-12 inch woofer makes a nice sub-woofer in a home theater provided it is connected in a reasonable way. One cannot simply parallel speakers, etc. Most AVR receivers do not have a subwoofer power amplifer, but only a sub-woofer preamp output. (Because there are many powered sub-woofers these days.) Drive the AR-1W with a separate power amplifer whose input is taken from this preamp output. If you have a good amplifer that is capable of driving 4 Ohm loads, then use the 4-Ohm tap. If your amplifer is not capable of driving 4 Ohms, then use the 8-Ohm tap. The AVR should have an adjustable crossover--usually adjustable from 50--200 Hz. I am not sure what you would accomplish with one 12-in woofer and a pair of AR-4x used in the traditional stereo mode. Perhaps with a pair of 12-in woofers, amplifiers and 150 Hz crossovers? At that point it would be simpler to switch to an AR-3a or AR-11!

Hi again Ed

I was using the tv speaker outputs to my satelite speakers and this was real nice for big movies.

Then I changed my plans and ran the high level wires to my main stereo.

Wow, was I impressed with how much better I could enjoy my home movies if they had audio effects.

If you can use the AR4-X's with your tv without another amp then just use this method to steer you into the mood.

After saying that, now if your tv has a high level left and right output to an integratd amp or pre-amp or receiver try this for an introduction.

You may already be doing this or more but please follow me a little more.

You should now have enjoyed, and I'm only referring to the AR-4X's now, a greater enjoyment of some movies.

Your next step would to have a center channel or mixed mono out to a separate amp with volume control.

I sure would suggest a electronic crossover but as John suggests if you have a sub woofer out, even better.

Now with a AR-1, AR-1W, AR-1X, AR-3 or ( AR-3A woofer preferred ) you would have the clarity of the 4X's and at times the bottom end that some movies seem to have.

You would have a controlled volume of that woofer so as not to overwhelme the audio, also a crossover compatible with the 4X's.

A center fill out can be generally wired in real easy but the crossover would be a little more expensive if that was the route you were to go.

You could also substitute the AR-2AX's for the 4X's but the bottom end wouldn't be quite as improved.

You could also wire the AR-2ax's front and 4X's rear in parallel with a w-w pot in the AR-4X's return cable as per David Hafler Dynaquad type system.

This would be probably a minimum cost system if you like it but there are still other choices available for you.

I feel you would have a very enjoyable system.

Good luck and please keep us posted as to your progress.

As always please fuse your investment.

Hi again

I did some more reading and a sub crossover should be about 50hz.

If it has a 6db/octive slope will still be audible at about 300hz but down in level.

A 12 or 24db/octive slope might be even better.

Hi there again

You may wish to chat with, " Subwoofer to go with AR-4X's Speakers " a new topic at this site today.

You both have the same or similar ideas and great taste.

Good luck.Vern
