Using an AV Receiver to Power Your Cerwin Vega's 

That crown 1500 is probably the best dollar per watt amp you could get if you only need to run one set of speakers. Under-rated for its power output and should have lots of headroom for those 12s.

@@SavingVegas Yeah it is. Powers them with no problem what so ever. I have an entire 5 channel setup all XLS model speakers, the 12's, 6C center, a pair of 6S surrounds. The center and surrounds are powered by an Emotiva BasX A3, 3 channel power amp. And to round things out I have a pair of SvS PB 3000 subs.

@@SavingVegas YES! I NEED TO GET ONE

The A & B channels are essentially only 2 channels, left & right. Running both A & B at the same time would be the same as hooking up 4 speakers on an amp with only one set of speaker outputs, one left and one right. The purpose of A & B outputs on an amp is to be able to switch between 2 different sets of speakers as need be. On the back of the receiver, it's probably written somewhere saying A or B minimum 4 ohms, A + B minimum 8 ohms.

I have since this video been able to take impedance measurements of these speakers. They are rated as having a 6 ohm nominal impedance but they actually measure closer to 4 ohms really, especially the VS-100.

Thats not true my dad had a yamaha surround receiver and it sounded amazing with music

@@Durkhead Try a real sterreo amplifier...We talk after...the receiver most of are class D...TRY a class A or A/B...Reciever=MOVIES

@GREENTICKETRO hardly any home theater receivers are class d that's why their still so big, most are class a/b you don't know what your talking about. There's more dedicated class d amplifiers than class a/b

@@Durkhead I know,you dont know.Lets stop here...

@GREENTICKETRO if you actually knew what you were talking about then why would you make such an ignorant statement

Not a real tech, as you can easily rebuild those woofers.

Unless you are using the D-9's for home theater I wouldn't use one to power the D-9's. I would find a good 2 channel power amp and pre amp. If you do want to use them for home theater I would find a AV receiver that has front channel pre outs so you could use an external power amp for the D-9's and control the power amp with the receiver. Not a lot of AV receivers like 4 ohm speakers like the D-9's are rated.

I don't think that Sansui would have any issues running a set of AT-12s as long as that is the only set of speakers hooked up to it. Most of the 70's and 80's vintage amps will handle even a 4 ohm load with no issue. Wouldn't hurt to keep an eye on it and if you notice it creating excessive heat then dial it back.

@@SavingVegas thanks so much for the response! This is what I figured. It's very interesting how many conflicting sources state the At-12s at 4ohms, but I was able to find a advertisement spec sheet that puts the AT-15s at 6ohms. Why do you think this is the case? Are the ohms hard to determine for some reason? Also, I'm buying them second hand, and the original owner says their foam was replaced with prylopropelene rubber a few years back. Does that sound accurate/acceptable to you? (Super appreciation your way, sir! Excited for this journey!)

I have never used any kind of rubber surrounds on CV woofers before. The surround material and stiffness will affect the sound. I would recommend installing foam surrounds on them but it is up to you. Some people think it's better because they won't rot but they were designed to have foam.

It should just push straight in and once it is pushed in push up and it should click into place.

@@SavingVegas I have tried that now, how hard do I have to push up? Because im nearly breaking my fingers 🤣🤣

It has to push in before up. Is the fuse in the proper position?

@@SavingVegas Yes it's in the proper position

@@SavingVegas I can put a video up on my channel and show

Is there a switch on the back of the amp to select impedance?

@Saving Vega's There are buttons on the front for selecting 2,4,or6 ohms. There are also buttons for selecting 3 pairs of speaker outputs. Would I short circuit things or gain nothing if I connected all 3 speaker outputs to the one pair of speakers?

I personally wouldn't bother trying to power them with an AV receiver. If your receiver has front channel pre outs I would use those with a good power amp. You can't bi amp AT 15s. Bi amping is when you use 2 different channels for one speaker, one channel for the tweeter and second channel for the woofer.

Guess I will try a Crown amp, thanks for your time

Yes some AV receivers will handle lower impedance better than others. I have had multiple Onkyo receivers over the years and they always preformed well but the newer stuff had some reliability issues. So my latest receiver I bought was a Yamaha which also performs well but have had to send it in for repairs 2 times now and it just runs a set of D-2's.

Of the few amps I've tried on them I prefer my NAD 216 power amp that I was using with my Adcom GTP-500 pre amp.

@@SavingVegas can you hook up a vinyl player to it

It is just a power amp so a pre amp is needed. Then a turntable would hook up to the pre amp.

@@SavingVegas ok thank u for help

🤣

Along with heat you also degrade the characteristics of the output transistors by making them operate outside of their design specs. You shouldn’t try this test. Not even for a few seconds.

Why are you sorry? I power my Vega's with a high current power amplifier. I do however use a AV receiver for my surround sound setup in my house but I have a seperate power amp running off the front channel outputs for my D-2's. I made this video because lots of people use them to power their CVs.

@@SavingVegas ok, not sorry. i just use my pioneer sx-780 works great

That's a good unit. Used to have a 680 and loved it.

@@SavingVegas cool. my current setup is : Pioneer SX-780, Behringer DEQ-2496 ULTRA CURVE PRO, BBE 362-NR SONIC MAXIMISER going in and out of tape monitor 1, SONY TC-WR590 Digital readout dual cassette deck in tape monitor 2, bluetooth module in the aux, PIONEER PL-518 TURNTABLE in phono, Cerwin Vega VS-150'S (one of which i need to re-cone again) in a spkr, and small Infinity RS-2000's in b spkr. But hooked to my PIONEER SX-580 is an Alesis MEQ-230 Dual 30 band per side eq, and in a and b spkr are 2 pairs of Bose 201 series 2 speakers. MY next project is to completely re-do the vs-150 speaker cabinets. Ud like to do them in actual walnut then polyeurethane or whatever that shiny clear crap is on bar tops on them so they look glossy. OR i might do them in clear or smoked acryllic.

I power mine with a Sony 1080 receiver works fine

I personally haven't delt with the XLS series Vega's much but I do belive they are rated at 8 ohms so your good there. They don't have the high sensitivity rating like most of the older models do so if you went with the 215's they are going to need some power. Surprisingly I hear most people aren't super thrilled with the bass output of them and most recommend running a subwoofer with them.

I've changed my mind, going with the XLS-15 , rated at 6 ohm , guess I'll be OK with my receiver, don't plan on cranking it up to high.

​@SavingVegas I have a question...what do you think about hooking up a usb fan to the switch outlet of the receiver..? I see that some folks are against it...I keep one on my sony av as soon as it cranks...

I run 2 usb fans with rubber feet on top my pioneer elite vsx47tx receiver, and it's cool all the time now even cranked for extended times.​@steven6692
