      I was all ready to spend up to five hundred dollars to buy Bose or Cambridge Works. I studied all the online reviews. A lot of people who seemed serious recommended the Logitech Z-2300 as being just as good. So I decided to buy that one since it is so much cheaper, but it seemed to be discontinued, and Amazon said that the Logitech Z623 is its “successor”. One of my requirements is the low end frequencies. I like pipe organ music, and the pipe organ plays down to the bottom of human hearing. An eight foot C is about 69 Hz, so the sixteen foot is 34 Hz and the 32 foot is 17 Hz. Logitech advertises that the Z263 goes down to 31 Hz, the Cambridge is similar, and Bose does not release the information. So I bought the Z623 on sale from Best Buy and hooked it up. There is a lot of talk in reviews about different ranges of hearing, and others talk about personal taste, but I use the “closed eyes” test. I listen to classical music, not artificial music, and I close my eyes and ask myself if it sounds as though an instrument is in the room with me. Does it sound as though there is a piano there, or a string quartet, or a pipe organ in the room with me? I started with Bach’s Passacaglia in C minor. It sounded to me as if I were in a recital hall with a pipe organ. I tried Sibelius Fifth Symphony, Rachmaninoff piano music, Brahms piano music, and various Mozart chamber music. I tried Mars by Holst, and piano concerti by Brahms and Rachmaninoff. I also tried vocal music by Palestrina and Josquin. When I close my eyes, I am unable to tell that I am listening to an IMac computer and speakers instead of live musicians. Some orchestral music sounds thin, but other recordings sound perfect, so I believe it is the recording that is at fault (or the compressed version on my computer) instead of the speakers. I haven’t done a blind test, but from what I perceive, I don’t think I could tell the difference between piano music on these speakers and the seven foot grand piano in my living room. Each time I listened to a piece, when I opened my eyes, I was surprised to see a desk, a computer, and some speakers.

      Decent sound for budget system

      Bought this system after getting annoyed with the previous system sounded like listening through a cardboard tube. Moved into a new place where the computer room is a lot smaller than the previous place. Last place had room for a full bookshelf speaker monitor system with separate amp etc. Needed something that sounded good, but didn't take up a lot of space. Picked up a used system from goodwill to have better sound from the tv in the rv. works ok for that but really bad for music. Numerous reviews for the new logitec system rated this system close to the top (with the best seeming to look like it came out of the museum of modern art) I te nd to listen to what is called progressive rock, or prog-rock. Instruments rage from light acoustrical winds and strings to heavy electric bass and drums. On the whole, I like the sounds from this system, Highs are real clear and bass will have you moving. Volume sounds good at low levels, but still kicks out pretty well when turned up. There seems to be a slight lack of clarity in some of the lower mid ranges, somewhere between the mids and the sub, but that may be mitigated with an equalizer program. Sub fits under my desk with no problem and the main units aren't too big or obtrusive. Speaker technology has come a long way since I was a kid. Would have killed for a set up like this back then. To get any significant sound improvement you're going to either have to go to the 5.1 systems or start spending a lot more money. Keep in mind this is in a 10x12 room, and bigger rooms will require more sound to fill it. What could be better? I would have liked to see better eq control on the front of the speaker. Only has a volume and bass level knobs. I've noticed a small humm coming through the speakers while scrolling through web pages with nothing playing. Could be my motherboard sound card section, or some other rf interference. Could be the wires and connectors need better grounding or shielding. Not a huge problem and only noticeable if you listen for it. Slight gaps in the crossover frequency, again mostly if you're listening for it. Otherwise a good unit and doing what I wanted it for.

      Solid 2.1 + Great Sound

      After moving my Logitech Z3's to my office, I was without a pair of speakers for my Mac at home. I was using the speakers for monitoring music production (in the rare event I didn't use headphones), playing my Line6 guitar through, and casual music listening. I finally decided to get a second set of speakers for home and after listening to other speakers in store (Kilps), I was less than impressed. Speakers in the same price bracket were lacking clarity and dynamics. Seeing these on shelf (but not displayed for testing), I looked them up on my phone to read a few reviews and knowing my satisfaction with the Z3's for about the same price, I was willing to jump before hearing them; glad I did. Though I'm not so pleased with the speaker shapes (kinda ugly), I was blown away with the sound. Dynamic range, high clarity, and the adjustability of the sub level really make this package an amazing bang for the buck. Though not audiophile level (IMHO) these speakers can do varying genres of music a lot of justice. As a musician with eclectic taste I definitely ran the gamut on this set: metal (djent/metalcore/Gothenburg/etc), electronic (4 to the floor, trance, dubstep, chill), jazz (standard and smooth), and pop rock/r&b/country. The sub can be pretty overpowering depending on the genre, but the bass level control really lets you dial in a good mix. These things are also super loud - I haven't worked them to over 40% volume at 30% bass. One day I'll rattle my upstairs neighbors >:-) In short: if this is what you consider to be a reasonable price range then definitely give them a listen (or pull the trigger like I did). You'll get good quality speakers that can give you some massive knock and some great projection through a room.

      Great Simple Sound

      Posted

      I use my Z623 system mostly for cable television viewing. Its secondary purpose for me is movies from my laptop and lastly music from my laptop. The most important pro about this system is its simplicity. I do not own a full sound system because I do not like all of the satellite speakers and especially the accompanying wires. My system is in a 450sq/ft living/dining/kitchen open area in an apartment. I have very little sound absorbing material in this space. The entire area is bamboo floors with no window treatments; so, it is usually very difficult to find good sounding acoustics from movies. This system sounds amazing throughout the aforementioned area. The 7" sub has amazing range and is not over-bearing. I have my bass amplifier knob set at 50% and it is perfect for my application. The volume capability is well above "domestic-disturbance" levels. I have yet to find a volume high enough to distort the sound. Granted, I only tested the maximum volume for a few minutes with country music, but was very satisfied with the clarity. The appearance of over-engineered mid-range speakers is very stylish and gives the system a high-quality look. The sub is exceptionally heavy for its size; this is a plus for me because it at least gives me the impression it is made of high-quality materials. I say, "impression" because I have not had this system long enough to fully attest to its true durability.

      Logitech z623 review + Bose Companion 20's

      Bought a set of (Bose Companion 20's) at Best Buy when my old Altec Lansing ACS48s' right channel died (after nearly 20 years of total awesomeness). The Bose Companion 20 I had high hopes for, especially since they are $249, and have some positive reviews. They sounded decent in the store. The audio quality rivals the old Altec Lansing set, but is severely bass deficient (The Altecs had great bass and sound quality all around). I suppose one giveaway is the AC adapter, which outputs 18v, 2A. I looked at multiple reviews and Boses' website for the wattage spec, I never found it, but that's a maximum total of 36 watts. So these are about 16W per channel max. Bose makes amazing sound with only 16W per channel, but don't expect any bass. To be truly great, the sound needs to be complete, not missing any spectrums. I ended up returning them. I just installed some Logitech z623's. (I'm sure all the Bose diehards are groaning..). To achieve a balanced sound, don't turn the bass up too high. I put it just past the center of the dial, but I think centered is plenty. Sitting at the computer the bass sounds slightly lower volume than when I get up and walk away from the computer. These definitely fill the whole room with great sound! On sale for $129 also (so half the price). The win for me was these Logitechs.

      These speakers would still even be a great bargain at 200 bucks. The bass hits like nobodies business and has no problem rattling walls and knocking stuff off shelves in my room. The only way I would see anyone even remotely being disappointed is if they were expecting the bass to hit like it was coming from a 12 or 18 inch sub. These speakers are set up in my decent sized bedroom and a majority of the time unless I really want to shake things up, the bass knob never goes past half and it still hammers. Now if I had to critique anything the sat. speakers can be a little too high pitched but really isnt a problem considering there is EQ options in most anything you are using the speakers for to remedy that. Also the volume control after you get to about the half way mark is very sensitive as to how fast the volume increases in comparison to getting to the half way mark. If you do want to crank up the volume you want to turn the sub down a fair bit and adjust it back up just to be on the safe side HA HA. For the price I got these at I wish I bought 2 or 3 of them and just put them up. These speakers are great watching movies, playing video games and I have yet to play a style of music that did not sound good on them. I ran them through the bass music and I listen to mainly metal and this sub brings double bass to life and rattles your insides. If you are not an audio snob who needs a 5,000 dollar rig to listen to music you will not be disappointed in any way with these speakers and that is my opinion :)

      Great clarity and deep bass. Only wish they were a little less directional. If they are even pointed slightly away from you, you won't have nearly the same clarity as if they were pointed at your ears. Also, the cord for the second satellite speaker (the one without the controls is a weak point. The connector can be fidgety and sometimes cause interruption or no sound at all to play if not plugged in perfectly, as it is succeptible to kinks and premature failure where it plugs in at the subwoofer. Aside from that, another home run for logitech, I previously have owned both of their home/computer 5.1 surround systems and have been very pleased with the brand overall. All my mice are logitech, my keyboard is logitech, it's simply a household brand. It is a minor shame that these inconveniences have plagued these and just about every other logitech system I've owned (the plug failure), but I'll still keep on buying logitech products. Also, despite the lack of independent tweeters, the treble is incredible. A+ (P.S., I highly recommend using a good sound card/high quality integrated sound card to get the best bang for your buck out of these, and set the bass cut-off somewhere around 55hz. You're not gonna get too low with these, but the notes they can pump out are loud and hit hard)

      Excellent speakers

      I bought these to replace a more expensive set of Klipsch 5.1 speakers for my office and I'm very happy with what you get for the price. The bass is maybe a bit less crisp than the Klipsch but is still very good. There is no noticeable hiss or distortion and the satellites sound surprisingly good. The Klipsch speakers I replaced had an annoying loud hum if left on when the computer was off, however the Logitech speakers are completely silent. I used a Kill-a-watt to measure power usage. It uses 1 watt when turned off, 5 watts when on but silent, and between 5 and 26 watts playing relatively bass heavy music at a volume level you would probably consider too loud for a small room (12' x 12'). I consider 5 watts low enough to just always leave it on and not have to worry about turning it off and on with each use. My only complaint would be that the cables for the satellite speakers are not long enough for a large desk. Not a big deal to get an extension for the speaker that uses an RCA jack, but the cable that goes to the speaker with the controls would be a lot harder to find an extension for. It would also help with speaker placement if there was a switch to flip which speakers are left and right. One other annoyance - there was no manual included.
