Logitech Z623 review: Big-sounding 2.1 speakers


Build 3. Oh how the mighty have fallen. When THX was first introduced as a standard all of the top brands rushed to get certified by Lucasflim. One of my Kinergetics Class A amps is THX certified, the amp needed to be biased for higher output to meet the spec back in The THX standard ended up getting spun off as a separate entity, and the blasphemers at sound card maker Creative Labs are the current owners.

The standard has been watered down to a loudness spec, ability to play 85dB with 20dB peaks, so just about any ole garbage can be THX certified. The Logitech z speakers follow the standard 2. While it may be the standard I'm not a fan of subwoofers and this is only the second product I've reviewed that has one. Satellites use a 2. The surround is a soft butyl rubber, and instead of a dust camp or whizzer there is a nice shiny phase plug in the center of the driver.

Back of the driver shows the z's are magnetically shielded and seem pretty well made. Removing the grills took a bit of paper clip folding, but came off cleanly once I applied the right amount of force. Grills are a metal mesh and seem open enough to not interfere too much.

The subwoofer driver is supposed to be an 8 inch, but once you remove the massive grill the driver shrinks down to a little over 7 inches across.

Stamped steel basket, big magnet, paper cone, and foam surround - looks like a pretty good driver considering the price of the system. No vented pole piece on this driver, instead there are tiny holes in the cone behind the dust cap to vent the pressure. Spider looks generic but functional. The satellites are two piece ABS plastic and have 6 screws holding the two halves together. Honestly this is probably good enough because the driver is so small, and crossover point so high.

The subwoofer cabinet is 9x12x11 inches and cheap mdf, but heavier than I expected. In comparison to the size of the box, the port on this subwoofer is massive. Power supply and amp boards are both built into the subwoofer. Lots of chips in there doing a bunch of stuff. I'm guessing there is some logic for switching inputs, some equalization, a crossover for the sub, and 3 channels of class D amplification.

There is no way to switch inputs and I didn't bother trying to play two sources at the same time, so I have no idea how switching is handled. Right speaker has volume and bass knobs.

Volume pot seems clean and I did not notice any imbalance or static while testing. Bass knob has a centering indent so you can find the default position easily. Also, there is a headphone output and an aux input on the side of this satellite. Satellites are very sensitive to placement. A slight toe-in and elevation with some blocks of wood make for pretty good imaging, although the sound is a bit too directional for my taste. Bass is really heavy, turning down the knob removes a bit too much of the Hz range without cutting the 60Hz mess that is actually the problem.

Just going to have to deal with the bass as is to keep the midrange balance. Sounds like three separate speakers with the sub being crossed too high and having an obnoxiously audible cabinet resonance. Midrange does not sound bad, maybe just a slight rising response. The z's are pretty awful, better than the Logitech z in stock form, but it's pretty bad. Turns music into movie special effects. Treble is spiky and headache inducing in the dog whistle range.

I've now got a massive headache from the treble. Fuck this shit, I'm done. These little sat sub combos are a pain to measure accurately. I've got to fight room modes in the crossover region, as well as phase cancelation and other not good things.

This is a close mic of the satellites. Keep in mind with close mic the treble response is going to taper off and there is an artificial hump around the resonant frequency of the driver. Regardless of the anomalies in the measurement it's clear above 6k the little full range drivers are having a panic attack from being played too high. For the bass response I'm using a technique I just came up with, "kind of close ground plane measurement.

Working from left to right. I cut a massive chunk of the bass, and then used that headroom to extend the bass to about 32Hz. There was a resonance of some kind coming from the subwoofer in the Hz range. I had to cut it, and it sounds better now. Leveled off the rising response in the midrange, and chopped the nasty cone breakup distortion above 10k. Audiophile music sounds great on this, of course well recorded music sounds good on almost anything. This is enough to get you evicted from most apartments, more importantly, it meets the THX standard.

Trying for more, the deep bass in M O O N's Release has headroom falling to about 95db at 35Hz before the subwoofer runs out of excursion. Bass coverage is pretty even with the subwoofer close enough to kick. Too much of the subs performance feels like port noise instead of driver, but for the most part it's doing the job.

Bass guitar is audible as an instrument instead of blending in with drums. The full range driver once corrected is actually pretty low distortion, and the amp sounds clean on this setup unless you push it too hard.

Still sounds like three speakers instead of a musical performance. I came in with extremely low expectations, and while the treble in stock form is unlistenable to me. The Logitech z's are noise makers, and nothing is going to change that. There is not a lot of musicality to the speakers.

To get musicality you are going to need to put up with less bass, and probably pay more money. Click here to download the DSP correction for this speaker system.

Superb bass response and an excellent stab at immersive THX audio make them easy to recommend, even if the satellites lack a little in detail. They have to be heard to be believed though, and despite our reservations about the THX certification, it actually seems to mean something here. These come highly recommended. The Z is an option for gamers or movie buffs who want the power of a 5. All other users need not apply.
