Hi, this is my fist post on these forums and I would appreciate any help.

I have recently upgraded my front speakers to the Cerwin Vega XLS-215. I am currently using a Pioneer VSX 1021-K to drive these. I have been researching and may need to upgrade the receiver and get an amp. I am looking at the Onkyo TX-NR809. Would there be a better (less expensive) receiver option if I am just going to run an external amp anyway?

1.) Will the Pioneer damage the speakers now? (Currently it sounds fine.) I like this receiver but it does not have any pre-outs for an amp. Amplifier Design Direct Energy Channels 7.1 Power Output Per Channel (20Hz-20kHz, .08%THD@8ohm) 90 Power Output Per Channel (1kHz@8ohm) 110 Power Output Per Channel (1kHz@6ohm) 130

2.) Can I run the Onkyo only for a while until I decide on the amp?

3.) Am I going to be able to tell a 'big' difference between the Pioneer and the Onkyo and these speakers now without any amp.

The Cerwin Vega XLS 215:

Frequency Response

38 Hz - 20 kHz (-3 dB)

36 Hz - 20 kHz (-10 dB)
Power Capacity: 500 watts (Peak )
Sensitivity in SPL: 95.3 dB (@ 8 ohms @ 1 meter full)
Impedance: 6 ohms
Crossover Frequencies: 280 Hz / 2.4 kHz


Thanks again!

Both receivers are 6-ohm stable so unless you're playing the speakers really, really loud, there's little danger of damaging the speakers or the receiver.

How much of a difference depends on what amp you're considering. So... what amp are you considering?

I really appreciate the response.

I was looking at 2 different receivers now: the Denon 3313CI and the Onkyo TXNR818 and I was going to add either the QSC RMX-2450, the Rotel RA-06SE, or a Crown XTI-4002.

Is this too much amp? Will I even need it with those receiver choices?

I was also looking at Emotiva amps.


Thanks!

Those are radically different products. The QSC and Crown are high-power rack amps, and the Rotel is an integrated amp with less power than the Denon and Onkyo receivers.

In my opinion, if you're going with that Denon or Onkyo, you probably won't need the external amp.

Ok, I will study the amps and see if I even need one after I decide upon and test out the receiver. I know these are power hungry speakers and I want to feed them what they need and not hold them back.

Thx. again.

I had one other receiver idea and that is a Pioneer Elite SC-61. They are stating this Class D amp (D3) would be full strength to all channels. ( It is rated at 125 watts of continuous power into 8 ohms at 1 kilohertz and 200 watts into 4 ohms.) It does have the pre outs so I could add the external amp.

Those are really NOT power-hungry speakers at all! With a sensitivity of 95.3 db they should be able to be driven to ear-splitting levels from your receiver. Where did you research these? (I realize they cannot say anything that is not true on the internet)rolleyes.gif

Well I pulled the trigger on a Pioneer SC 1522K. I will see if I can tell a difference between that and the VSX 1021-K.

I do want the speakers to preform their best. When I said "Power-Hungry" I was thinking I should have a few watts of headroom so that I don't clip the speakers and so I should get a good preforming amp.

Thqt is a very high sensitivity. Probably 89 or 90 is average for most speakers. The more sensitive they are, the less power they need for the same volume.
But it is your money, and whatever makes you happy!

Right, they are efficient. Please help me understand why I would want to add an external amp? If it's not necessary I can always return the receiver.

Thank you,

All you need is the receiver. You really will not gain anything from an external amp with those speakers unless you are trying to fill an auditorium with sound.

It's hard to say how difficult those speakers are to drive based solely on the spec sheet. Usually a dual woofer speaker with high sensitivity is going to be a 4 ohm load. The previous generation CLS-215, which is pretty close to the same thing as the XLS definitely dipped below 4 ohms through out the woofers operating range. According to CV it was an "8 ohm" speaker

i realize this is an older thread but the title is exactly what i'm asking so i figured may as well keep this thread going...

 

moved into a new house and now have a fully finished basement with a bar.

my current yamaha receiver and klipsch f10's aren't enough for the way i like to party!

was fine in my previous albeit smaller home.

 

so far i'm seriously considering a pair of xls-215's and the cv-1800 amp to power them.

 

http://www.cerwin-vega.com/home-audio/floorstanding-speakers/xls-215.html

http://www.cerwin-vega.com/pro-audio/high-performance-amplifiers/cv-1800.html

 

the receiver is the part i'm scratching my head on.

 

an overloaded ht receiver is just not something i require because this setup will only be for playing music, so i'm considering this receiver.

 

http://ca.marantz.com/us/Products/Pages/ProductDetails.aspx?CatId=AVReceivers&ProductId=NR1403

 

any reasons why this is not a good choice?

or any thumbs up ??!! LOL

 

thank you in advance for the opinions folks ;-)

jason did you get the cv1800 for the xls215 ?  if so did it make a diff with or without ? I also have the xls215 and was considering the cv1800 . right now im just using a yamaha HTR - 5990  amp that is 120w in stereo at 8 ohms. It sound fine but amp shuts off at -12 volume and id like more bass to it if possible. let me know .

For what it's worth I'm extremely pleased with the sc1522k pushing these speakers. They blow the doors off of my house but with that said I'm sure you could push them even harder. They are so great as I'm sure you know so I wanted to make sure they could reach their true potential.

If you guys have anymore CV questions I can help. I have an all CLS 7.4 theater with CLS-215's for mains and dedicated amplification. The amplification that you will need for these speakers depends on several variables. These are power hungry speakers with large impedance dips. The advertised specs don't show that. These speakers can play pretty low but the XLS-215 was really designed to be used with subwoofers. My CLS-215's can play down to 25hz but where your mains are located is usually not the best place for bass response. I use four 15'' subs with my CLS-215's and I let my subwoofers handle the lower bass and some mid bass. I let the mains handle the upper mid bass. The bass response in my room is scary tight and hits hard. Double bass drums sound awesome. I also have my system calibrated pretty much by the book.

i love these speakers i use a sc-07 and a cv-1800 to power them the receiver powers the tweeter and mid the cv-1800 powers the woofers had them bi wired with the sc-07 just not enough power for the speakers  tried just powering with amp channel separation seemed a little off bi amped them unreal i love it loud but clean

You do understand that the way you have your speakers wired does not split the power going to the tweeter and midrange and allow the large drivers to be powered by your CV1800. The only way to do that is to remove the crossovers in the speakers. All you've done is run a bunch of extra speaker wire.

The CLS also has four binding posts with a jumper plate. It's a gimmick. They're not able to be bi amped. Bi wiring them also does nothing to improve the sound. You're misunderstanding true bi amping. It's complicated and you're not doing it with your speakers. I just checked the XLS215 manual. It talks only about bi wiring. It mentions nothing about being able to bi amp. I'm sorry but you're mistaken.

I have to admit. I think I have to eat my words on what I said. I just pulled out my paper manual. It says it is possible on these speakers. That's unusual. If you truly have no volume on your 15's with only the receiver on then somehow it's working. I'm wondering how the internal crossover section works while doing this. I don't see why you would want to bi amp them because the tweeter and mid use very little power. The CV1800 has plenty of power for the entire speaker. It's easy to blow tweeters the way you're powering them. Sorry, I haven't read my manuals in a long time. You where right.

No. I haven't tried it. I have plenty of power available with the dedicated amps that I have. I wouldn't want to mess with multiple volume controls anyway.

In the past I used my CLS-215s in a 2.0 configuration. I found them a little harsh. Since then I use quad subs and set the channel trim levels in my AVR. Now everything is smooth and not harsh. Do you use subwoofers in your system?

How do you set the channel trim level on the mains at 75db during calibration since you have multiple volume controls? What crossover do you use for the mains?

I also believe passive bi-amping, and bi-wiring are a complete waste of wire and time, however virtually all speakers I am aware of with bi-wire posts on the back, DO send the signal to different parts of the crossover. So if the jumpers are removed from the posts, and you hook up to say the HF posts, you will not hear bass, and vice versa. The crossover is still in there, and still doing it's crossover thing, but it is separate sections.
