Howdy all,
I'm looking at purchasing a new surround set of speakers, specifically the Magnepan 1.6QR's, CC3, and MGC1 for a 5 channel set. Small problem, I don't think my receiver can drive them.

My reciever is a Pioneer Elite Vsx-33Tx THX Select rated at 80w x 5 into 8 ohms. The reciever is only selectable down to 100 x 5 into 6 ohms. Pioneer customer support recommended against running 4 ohm speakers with it.

So, what do y'all think? Can my reciever drive this set or am I up s*** creek without a paddle? If I'm dogged with my receiver can someone suggest a reasonably priced amplifier or receiver that can do the job. This is an unexpected cost for me and as this is my first foray into audiophile priced speakers (sorry can't afford the Krells and the JMs yet.)

My uses will be primarily movies/tv, video games, and the occasional album auditions. Thanks in advance everyone.

~Andrew

Your concerns are well founded for at least two reasons.

I can't comment from experience on the other three speakers but I do have experience with the 1.6's.

First off, your receiver manufacturer specifically cautions against 4 ohm loads to limit the current it produces. Why would you want to second guess them, particularly with these VERY inefficient speakers?

Secondly, as I stated above, those 1.6's require a LOT more power than your receiver can deliver. I was driving mine in a two channel only system with a NAD 214 (80 wpc @ 8 ohms) power amp and it was sucking it dry big time. ...and I was using a subwoofer, too.

I upgraded to a Rotel RB-991 (200 wpc @ 8 ohms) power amp to keep them happy. It was worth it. Personally, I think the others would benefit from more power also.

You ARE figuring on a subwoofer also, aren't ya?

But ultimately, it's your call.

Have you listened to Magnepans? I really enjoy their sound, but I don't think they'd be the best for movie watching, as they aren't super dynamic. If you have listened and found them to be what you're looking for, then that's great. Keep in mind some important things with Maggies:

You need a lot of power to drive them, even the 1.6 models that you're looking at. Your receiver will NOT be able to drive them. You might be able to use your unit to drive the surrounds, but not the mains or the center.

The mains need space. Because of their dipole nature, they will need to be a few feet away from rear and sidewalls to get proper sound. You can't stuff them in a corner.

You will NEED a subwoofer. This is not a suggestion, it is a requirement. I suggest you take a look at models from Hsu for excellent value and sound.

Thanks for the feed back.


"You ARE figuring on a subwoofer also, aren't ya? "
Yes, infact Jax has me spot on, I am considering a subwoofer from Dr. Hsu, I am waiting on the release of the new 12" model to augment my speaker seletion.

Jax:
I have listened to the Maggies and were quite pleased with their sound. I plan on doing another round of auditioning with a more intensive focus on movies before I make my purchase though. As far as space is concerned I plan on placing them between 12"-18" off of the front wall, I am not sure if this is enough though they will be next to a pair of shelves on each side.

I have auditioned Mirage Omnisat's, Def. Tech's Super Towers, JM Labs entry level floor speakers(Chorus? I think), and the normal array you would expect to find, Klipsch, Polk and Cerwan Vega FLoor speakers. I left a pair of Infinity 15" floorstanding loudspeakers with matching center and surrounds behind when I moved. Anything else you think I should seek out and listen to before I make my final selection? Reccomendations are much appreciated.

Mark:
I'm not trying to second guess the guys at Pioneer, I just wanted to make sure I have all the facts as I know customer support doesn't always tell the true power behind their products... sometimes less, sometimes more.

Also, do you think I would be better off getting a 4 ohm receiver or purchasing a seperate powered amplifier and using my current reciever as a controller? I have a couple CROWN amplifiers lying around which are rated I think around 200 watts into 8ohms x 2 channels. Is it worth trying to use these at all? Suggestions?


Thanks a million gents!

I think that the crown amps will do the maggies just fine. I personally have a magnepan front end in my system and very few other speakers if any (in the price range) can compete with the seemless integration and amazing imaging of magnepan. I think that you will be very happy with your system. If your reciever has pre outs then I would just use that for now, and if you find that you are unhappy with it then consider a replacement. Maggies are absolutely fantastic for home theater, provided that they are limited in the ammount of bass that is going to them, and are complemented by a good sub. Anyone that is doubting the use of maggies for home theater has obviously not heard a properly set up magnepan theater (or one at all for that fact). I hope that you enjoy the maggie experience. Just remember that once you go dipole that you never go back.:):):) Happy Listening.

I agree with Soniceuphoria.

Use dem Crowns! They are perfect for the maggies. They have the brute power those 1.6's respond to. The 1.6's like the rough stuff.

Also, I've found that the 1.6's are polite enough to simply ignore any bass t hey cannot handle. Instead of "farting out" , they simply do nothing. In my system, I run them as large. they handle what they can and the sub takes over from there.

If you get a chance check out the new Monitor Audio Silver RS line. Just got a look at them (still waiting to hear them) - they are gorgeous! I understand they sound as good as they look. I am very excited about these speakers. Obviously very different sound than the maggies, but definitely worth a listen.

Well I guess I need to pull the crowns out of the closet then. Thats good to know that can use them for this. I'll be using two of the newer xls 202 amps and an older custom built model.

I have one of the wire "Metro" racks that I'm using for all of my equipment now, as this is an open design do I need to do anything about cooling them, or can I simply stack the units on the wire rack and run them?

I'm not familiar with Crown amps, per se.

I was merely recommending hteir use based on the available power and, if my memeory serves me well*, their ability to handle low impedance loads with relative ease. I don't know how hot they wil lget but I would recommend at least not stacking anything on top of 'em. I would say this is good advice for any power am but moreso the more powerful ones, and these qualify.

*Hey, I'm 56, graduated in '67 (the summer of love) and had a lot of fun when I was younger. Hell, I'm just happy when remember where I parked my car. :D

The others have told you correctly. The 1.6's are a 4 Ohm speaker and they "must" be driven by an amplifier capable of driving a 4 Ohm load. The good news is that although the 1.6's are rated at 4 Ohms, they present a fairly consistant load and do dip much below this point so they aren't nearly as hard to drive as some other speakers. They're also very inefficient and need all the power you can give them. I have a five channel Outlaw model-750 and it does very well. How much power will depend on your room size and how loud you listen.

I disagree they don't have any usable bass, because they do and on allot of music they actually sound better without a sub if you have sufficient power. If memory serves their -3dB point is 40Hz, which isn't bad. As you know they have a sound unlike any other and for most music are very hard to beat. The bass is not as deep and powerful as many speakers, but it has the unique Maggie sound with great detail and realism. Acoustic bass is just unreal on these.

Placement is critical, but you don't really have to get them 3' into the room before they come alive. It all depends on the room. In my room they actually sound better about 2' from the rear walls. Getting them out from the side walls seems to be more important in my room. I also have a very large entertainment center between the speakers and they sit next to the front edges of the cabinet. Of course I lose some of the depth, but the wide soundstage is still there and cabinet acually helps to reinforce the bass. IMO they can be made to sound good in most situations, maybe not optimum, but still very good with the Maggie magic in-tact.

I must also tell you that I have been looking for replacments and will be putting mine on the block. Yes, they are great for music and they are also very good for HT, but in a differenct and subtle way. However, the one area they are not really good at is dynamic's and this is what HT is all about IMO, especially for the action movies which are my favorites. I probably use my system for HT 90% of the time so I've decided to shift to a speaker better suited to HT than music. If it were the other way around there is no way I would part with the Maggie's, but I'm getting older and just don't listen to music nearly as much as I used to. YMMV.

Just some things for you to consider, hope this helps. Good luck, let us know how things turn out.
