Do I need an amp? (Receiver to Speaker question)

by onoano / December 3, 2007 11:58 PM PST

Hi. I'm trying to put a system together. I have a sony STR-D365 receiver and two cerwin vega E-715 loudspeakers that i'd like to put to use for a dj setup. The receiver specs are AC 120V 60Hz 186W. The speaker specs are 15" 3-way floor stander, 400 watts power handling, 102 dB sensitivity, Self-resetting tweeter, 81 (36Kg) pounds a piece, One red-ringed driver per speaker.

can i plug the receiver straight to the speakers without burning it out? or will I need an amp of some sort? any suggestions on an amp? I've never used an amp for a stereo setup before.

Also, the speaker cable inserts on the speaker have a red and black plug in and a fuse cap. I think it takes the cables with the jagged end tip, can anyone tell me what these are called?

One other note, the receiver I have says Impedance use 8-16ohms. While I believe I may have read that the speakers work with receivers of 8 or under ohms. Does this overlap?

Thank you.

The Sony is your power source.

Since the receiver & speaker specs both list 8 ohms (the most common figure), you're covered. In addition, because the speakers , @ 102dB, are highly efficient, you should get pleanty of easy volume through them.

I'm not up on all speaker connector types (& there are several). Just make sure you are getting a solid contact as the connector.

are we talking about practicing or having fun in your bedroom....

or are we talking about shows for the dancing masses?!!?

even if not the latter, if you like it loud, and you are using it in a very large space, with all that heavy repetitive bass found in techno, etc, you might want a "pro-amp" of sorts. They don't sound as nice as audiophile equipment (more distortion), but they are designed for that kind of thing... (LOUD)...

Well I used to Dj quite heavily and am just getting back into it. don't think i'll need them for events. just want loud and clear audio. So, loud is good, but i don't need the bass to over take the sound. Should I still get a 'pro-amp' do you have a recommendation? i will mostly be using it for drum and bass and scratching, and don't want to blow these beautiful speakers.

thanks so much!

I would ask other DJs or some other professional. They will know better than most, I would presume. The first thing I might look at is Behringer. They have 3 models, and all provide bang for buck. We talk about the entry level A500 with some frequency here...

Remember that its easier to damage your speakers with too little power (clipping) than with too much power. In your case, however, I do have to remind you that too much power can still blow speakers!! Silly

will it clip and blow with the 186W 8-16ohms specs?

I believe your receiver stats are for consuming 186 watts.
by NM_Bill / December 4, 2007 1:22 PM PST

The output per channel is 80 watts into 8 ohms.

Considering the high efficiency of the Klipsch, that provides very decent volume in normal size spaces, but for DJ type use a good alternative would a Behringer (widely distributed to guitar/pro sound shops). For $300 their Reference Amp A500 provides output of 160 watts per channel (stereo) into 8 ohms. Ho0w's that for bang for the buck?

Adding to what jostmeat said.

I recommend that you get a pro power amp and good DJ mixer.
Home AV receiver are NOT designed for that kind of use.
If you need a source repost. John
