Jamo C803 Bookshelf Speaker Review

Jamo C803 Speakers

Jamo C803 Speakers

The quality of loudspeakers being produced by most companies these days is pretty good. Rarely does a set of speakers come in for review that just sound awful. Each pair generally has strengths and weaknesses, but overall, I have found that there are many quality products out there to choose from. You can almost always find a speaker that combines good performance with a size, shape and aesthetic appeal that suits your personal taste in most any price range. With that being said, it has been a while since a product just blew my socks off. Enter the Jamo C 803 bookshelf speakers.

Features & Listening Impressions

I contacted Jamo and inquired about getting a pair of speakers to review. Visiting their website, I found that the Danish company has quite a large range of speakers. After some discussion, they suggested I audition a pair from their Concert line, and they sent me the lone bookshelf from the C 80 series (the top of the Concert line), the C 803. The Jamo Concert series is designed to deliver "a thrilling performance." Jamo also describes them as being built to recreate the perfect concert experience. Of course, this all sounds great on paper, but what would the reality be?

The 803's arrived wearing a Black Ash finish with black fabric grills. This is a large bookshelf speaker, best suited for mounting on a stand. I put them on 23" stands in my listening room which aligned the tweeters at ear level from the listening position - the desired placement for any bookshelf speaker.

The cabinets are rock solid, and have an interior cross brace, positioned just below the bass port near the back of the speaker. Each speaker weighs 21.8 lbs. The cabinet has a sculpted design that curves gracefully on the top and sides. The resulting look sets this speaker apart from other bookshelves before you even hook it up. The top of the speaker is capped with a glossy piano black plate that accents the unique shape and adds a touch of elegance. The cabinet itself measures 8.9" wide by 15" high and is 13.4" deep. It is a rear-ported, 2-way, bass reflex design. The fabric grill has a thin, low-profile plastic grill that is easily removable, and tapers slightly at the bottom, again adding a subtle touch of style to the overall appearance of the speaker.

The beefy 7" drivers are black rigid cones that are built to handle high power and a wide range of low and midrange frequencies. (The speakers have a rated frequency range of 45-24kHz.) According to Jamo, the cone consists of two layers of fiberglass, glued together air-tight around a paper honeycomb mesh. This creates an ultra-light and very hard cone that is perfectly suited for a driver. Unlike typical drivers with a dust cap in the center of the cone, the 803's feature Jamo's Centre-Plug, which is a silver, hard metallic stationary "bullet-style" plug that the cone moves around. In addition to cooling the voice-coil, it also allows the cone itself to be lighter and more responsive which results in higher power-handling capability.

The 1" dome tweeter incorporates Jamo's Decoupled Tweeter Technology, which actually decouples the tweeter from the cabinet to reduce transmitted vibrations that can color the sound. This technology reduces vibrations by more than 20dB. Jamo has also incorporated a specially shaped faceplate for the tweeter, which results in a wider axis of dispersion when listening to the speaker. It was not difficult to position the 803's for an optimum stage.

One of my favorite songs for a listening evaluation is Rat by Train, which is on their self-titled debut record from 1998. The recording is spacious and laid back, with a fantastic groove. It begins with a simple hat-snare-kick, warm bass line, and clean, bluesy guitar with a mellow vocal that all builds up to a chorus that gets pretty busy. I love to crank this up and push a set of speakers as hard as they will allow. At the end of the chorus as vocal, guitar and cymbals are crashing together, a harmonica lick comes in, at which point the mix gets a bit cluttered and crowded. There are very few speakers that I have listened to this song through that can keep it sounding decent. The soundstage usually falls apart and gets pretty harsh. As the verse begins again everything smoothes back out. The Jamo's made me feel as though I was in the studio as the track was being laid down. The bass was very well defined and warm, and you could almost hear the room the guitar amps and drums were recorded in. As the chorus came, it all held together better than I have ever heard. I still find the mix a bit harsh at that point of the song, but I realized how telling this section is when it comes to speakers.

I continued to put them through the paces of disc after disc, genre after genre of music and found them to be consistently balanced. Early in my career I spent many years in the music business, and logged plenty of hours in the recording studio. There is nothing quite like sitting in a control room listening to live tracks being laid down. You are hearing music as it is meant to be heard in that environment. The best way I can describe the C 803's is that they are the most musical speakers I have heard in long time.

When I think of home theater speakers, I always think of the main left and right speakers as towers. Ever since I bought my first Dolby Digital receiver, I have had tower speakers up front. Sort of that "big speakers equals big sound" kind of mentality, I guess. So I was interested to see how the C 803's would sound anchoring my 5.1 system. Again, I was not disappointed. I love the score from Disney's Pirates of the Caribbean. I love how big the sound stage is in movie scores, and this one of my favorites. It is just HUGE. I popped in the disc and went straight to the end credits and to my delight it was as big as ever. I could just picture Hans Zimmer and his symphony spread out in front of me. The Jamo's actually surpassed my older tower speakers in clarity and definition. Going back to some action scenes in the movie, the speakers handled things well enough that I am convinced you would not be disappointed having them as your mains in a 5.1 system, ideally matched with other speakers from the Jamo Concert series.


At any given time I have several sets of speakers in my listening room that I am evaluating. Several buddies and family members will drop by from time to time and want to see and hear what I am working on. Over the past month the Jamo's have been the consistent favorites of all who have heard them.

Sometimes it's hard to write such a glowing review of a product - the impression is always that there is some kind of alternative motive. The fact is, I had never heard Jamo's speakers before now, and I had never met anyone from the company. What can I say? I loved these speakers, and I am thrilled to have a forum to tell people about products that I love. I have never been so reluctant to pack up some gear and return it to the manufacturer, but so it goes.

Are there any negatives? Well, it depends. You certainly will want a big boy amp or receiver to drive them, as they are 6- ohm speakers. But if you are considering a pair of $800 speakers, I would expect that you already have a respectable power source. And at $800/pair, these are not inexpensive speakers. The price will be out of reach for many people. But I feel they are well worth the money - they are certainly not overpriced considering the quality of their construction and performance. If you are in the market for speakers in this price range, you owe it to yourself to at least take a listen to the 803's. I think you will be glad you did.
