Can I drive LSI-25 with Denon AVR-5800?

philbers

I'm thinking (still) about buying a pair of LSI25. I have a Denon 5800 receiver rated 175 watts/ch at 6-8 ohm. Did any one use this combination before? Will it damage the Denon? Can get good sound out of it? I currently drive a pair of Kappa 8.1.

I appreciate all advices!

Thanks

Why not do the LSi15's and put the extra grand towards a good sub? You'd have a much better sounding setup IMO. I'm really not a huge fan of the 25's, something just doesn't sound right to me.

Yes, I think you can. The 5800 is a beast.

I have a 15" sub but could never get the sub & main sound right together for music listening (It's great for movies though). I'd like to try speakers with built-in sub like lsi25 or Infinity Intermezzo 1.4. I heard the lsi15 at a showroom. It sounded pretty thin to me comparing to my Kappa 8.1 and my old Polk SDA-1C.

I love Denon 5800. It's more than a great receiver/amp! I'm afraid that the lsi25 with 4 ohm may damage it. Denon manual says 6 to 8 ohm spkrs recommended. But I really like the lsi25. I heard it a demo. I like its look & sound: full & warmer (I guess the sub made it sound warmer comparing to lsi15). My room is 15 x 27.

No offense intended, but this is a dead horse that has been beaten over and over and over.......
If the manufacturer of the receiver states clearly in black and white that the receiver is rated for a 6-8 ohm load, it isn't going to last very long or perform as well driving a 4 ohm load. The Lsi speakers will provide sound that will astound, stun and amaze, all YOU have to do is feed them properly. Invest in equipment that will bring out the best your speakers have to offer, not in something that will limit their performance. Push the 25's hard with a receiver that isn't rated to handle the load and that receiver will go into "Protect" mode early and often.

Frank,
Thanks for the advice! Point well taken!

The main issue is going to be temperature... all those little IC's, capacitors, resistors, etc in your Dennon are rated to last an average time based on a certain temperature. 4 ohms speakers are going to make it hotter and they'll break sooner. How much sooner is debateable, especailly since the amp will turn itself off if it gets too hot, but it's a risk you run. I ran my LSi25's off a Yamaha rx-v2400 for awhile and it worked, and the yahama is still alive, but it'd shut off around half volume and LSi15's are going to be just as hard of a load (if not worse).

So. You can do it, but figure on getting yourself a seperate power amp sometime not too far down the road. In the meantime, make sure you give the dennon PLENTY of room to breathe and if you can stand the noise, putting a fan on it would be a big help.

unc2701,

Thank you for sharing your thought!

It looked like I would need a separate amp. Urh!

Thanks

Frank Z,
I just click on your "MY HT" link. You got a nice HT system there! I had been considering the Sony HS20 for a while but ended up bought the Sharp x-zv9000 DLP for its long throw len for my room size.

It's cool!

Thanks

Thank you Sir!

The Sharp DLP's are sweet!
