Wild goose chase wins for the best answer! An extra 200 mile trip through LA traffic but they fixed it right this time. It works great now on both systems. This is the best sounding amp I've ever heard. It is currently running with a full time cooling fan on a 7.1 channel Jamo system. An interesting note however---The Jamo speakers have a 4/8 ohm switch. Most read about 7 ohms in the 8 ohm position and very close to 4 in the 4 ohm setting. I doubt the problem was in any of the speakers though. They all sound great and are working fine. Bottom line is I picked up an awesome piece of equipment and a give away price. Denon and Klipsch make a great team.

p>The previous owner had the same problem with this receiver. I took it to the factory authorized Denon Supercenter in Carson CA for repairs figuring they could solve the problem, but its still happening. They have it again right now, but the lady at the counter insists its my speakers. I still can't understand why a decent amp like the 3803 works and the audiophile quality 4806 is so finicky. I'm going to try it out on my other system when I get it back and see what happens.

My audio system has 7 Klipsch speakers and a Klipsch Sub. 3 RVX-42s, 1 RCX-4 center channel, and 3 RSX-5s. I've been using a Denon AVR-3803 to drive the system and it sounds great with no problems. I recently got a great deal on a Denon AVR-4806 and hooked it up to the system and soon blew a fuse in the amp. I took it the a Denon Super Center for repairs and when I got back the same thing happened. The tech there told me to check each speaker with digital ohm meter to verify impedance. I was surprised to find not one speaker with more than a 4.8 ohm reading. The center was only 3.8 ohms. These are supposed to be 8 ohm speakers. Just to remove speculation: These readings are accurate (verified with two separate meters). All connections are correct. I know this amp is WAY too powerful to drive 75watt speakers, but I never attempted to really rip it. The speakers have been driven in moderation for their entire life and not abused. The system works fine with the smaller amp. Now for the questions. What would cause all seven of these speakers to change impedance this way? Is there a cost effective fix available? Why does the AVR-3803 work fine and high end AVR-4806 blow fuses? Any knowledgeable input will be appreciated. I'm probably going to just sell the 4806. I've only got about $350 invested in it if anyone is interested. 100% functional with everything included.

Best place I can think of for anything that came from Bose.

I've got four Klipsch RSX-5s to fill out the 7.1. I started with a 5.1, then went to 6.1, and finally 7.1. Each time I added another speaker it sounded better. I drive the system with a Denon 3803. It has a 7 channel stereo setting that sounds amazing with music. The RSX-5s have been discontinued but they are still available in new or like new condition for around $100 ea. I mounted mine upside down to the ceiling. This allows a much greater range of adjustment than wall mounting, is easier to wire, and still looks good. Another option would be flush mount speakers. They require cutting into the walls and should be thought of as a permanent installation. Too big of a commitment for me. Klipsch flush mounts are expensive. A good alternative is Jamo (by Klipsch). Let us know how it turns out.

I haven't got a chance to listen to the the Velodyne, but I recently bought a XW-500D from Vanns (Stole it for $375 on clearance) and I can tell you the damn thing rips. It replaced an RW-10D and it makes a huge difference. Size is very compact and it looks very classy with a high gloss back top. It would be an excellent match for the rest of your system. I also have an XW-300D. The thing is the size of a toaster oven and puts out big time bass. You wouldn't go wrong with either one.

I have a Klipsch XW-500D and an XW-300D. Even the smaller one plays all the way down to 22Hz. Both are adjustable with a top mounted LCD. Sub-10 and Sub-12 have a dismal record of reliability. I had Sub-10 that ate fuses like M&Ms. Sold it the first opportunity and don't regret it a bit. No such thing as too much bass capacity. Thats what adjustments are for.

This sub worked fine for over a year until I lent to a friend for a few days. Now it blows the fuse as soon as the the switch is turned on. Suspect it will need a new amp plate. I found a good RW-12D plate for $60. Does anyone know if they are compatible. The 12D plate is 350W as opposed to 260W for the 10D. New plate costs $166.95. I wasn't too impressed with the hardware when I opened this thing up and I don't want to spend more than its worth. Suggestions appreciated.

Have you had any unshielded speakers close to it lately. Even the shielded type can really mess up a TV sometimes.

Don't pay more than $25 for it. It's a dinosaur. Older high end receivers are all over Ebay for $100 or less. Check out Marantz or Denon.

If you are planning a home theater setup, allow me to make a few suggestions. First you need a center channel. It does much a the work for movies and TV sound. A subwoofer, (the .1) will take the sound to a much lower Hz level and remove the burden of playing bass from the other speakers. I just bought a Klipsch XW 500-D and recommend it highly. Flush mount ceiling speakers in the kitchen wouldn't take up any space and would greatly improve the sound quality. Most Denon amplifiers have a "switch" that will take the sound from Cinema type sound to 2,5, or 7 channel stereo with equal sound in all channels---perfect for music applications. The better ones even have a 2nd or 3rd zone capability where different source can be played in another area at the same time. Lastly, try Vanns.com on the net. They have reps that can provide good advice on what would work best. They are an authorized Klipsch dealer and their prices are hard to beat. Good luck.

After comparing the XW-500D to the RW-10D back to back I can truthfully say the XW is better in every way. Deeper, tighter, stronger base you can feel in your chest and back and in a smaller package. The spec sheets tell the same as a sound test. Build quality is very high with the exception of the cheesey grill which I immediately tossed. Nothing wrong with the RW. I'll probably keep it, but it just got demoted to the garage system. One thing still puzzles me. Why does Klipsch design their better subs with remote capability, and not offer a remote control? A good idea half complete. I don't like programmable universal remotes, and I'm not about to buy one just to run a sub that should have came with one.

I just bought the XW-500D open box with full warranty for $375 OTD. For those who haven't found Vann's Clearance Outlet, I suggest you check it out. Will do the Pepsi challenge and post the results soon. I may end up moving the RW-10D to my garage system to replace the Klipsch SW8. I can use extra power to neutralize the cRAP the neighbors play.

Looks like you have the experience and equipment to provide and informed opinion. Actually, I already have the RW-10D and I'm pretty satisfied with it. I have a hard time calling a system complete when I put one together. I bought the 10D for $150 and I have a chance to sell it to a customer for $250 and pick up an XW-500D for $400. I also have have a hard time passing up a good deal. I haven't been able to find too many reviews on the XW, just new buyers gushing about their first sub. Is the cerematalic cone driver in the 10D better than the fiberglass cone driver in XW?

Subwoofer question. Which would you rather have? A Klipsch Reference RW-10D and $150---or a Klipsch Icon XW-500D. My system has a Denon AVR3803, 3 Klipsch RVX-42s, and 4 Klipsch RSX-5s. Entire cost with cable under $1000.
