Logitech Z-2300 : The Last of the Titans - Page 7

Thanks for posting that information.  I will probably scratch them off of my list as I continue hunting...

Thanks again.

 

I avoid Dayton audio products. They quality of engineering & craftsmanship is not upto the mark. They normally recall a lot of their products. Look below at their latest recall:

Consumer Product Safety Alert

At Parts Express, our efforts are continuous and on-going to ensure that the products we sell are not only an excellent value, but are also safe and reliable. As a result of those efforts, we have identified the following models to contain amplifier modules that have the potential to produce extreme heat, smoke, or fire:

Dayton SUB-100 HT Series 10" 125 Watt Powered Subwoofer (SKU # 300-633 & 888-632)
Dayton SUB-120 HT Series 12" 150 Watt Powered Subwoofer (SKU # 300-635 & 888-634)
Dayton Audio Speaker Bar and 10" Subwoofer Package (SKU # 300-637)
Dayton Audio Speaker Bar and Subwoofer Package (SKU # 300-638)
Dayton HTP-2 5.1 Home Theater Package 10" Powered Subwoofer (SKU # 300-694)
Dayton HTP-3 5.1 Home Theater Package 12" Powered Subwoofer (SKU # 300-696)
Replacement Sub Amp (SKU # 000-RET1)

While the quality issue is known to have affected less than 0.5% of our total units purchased between June 30, 2010 and January 15, 2011, we believe units with serial #'s 0608010101 thru 0608010500 require an upgrade. If you possess an amplifier purchased in this time frame, immediately unplug the unit to eliminate any risk of danger, regardless of whether you notice any problems with the unit or not. If you purchased this unit for resell, please contact your customer to have the unit's serial # checked. To check the serial # of your unit, view HT100-120 Amplifier Removal Procedure

.

We have identified an over-heating issue in the amplifier module of the sub. This heating issue can occur at any time that the amplifier is plugged into a wall outlet, whether it is actually in use or not. Problem over-heating of the amplifier is usually accompanied by a very noticeable "hum" coming from the subwoofer's speaker. If left powered, it is possible for the metal "plate" and heat sink (cooling fins) of the amplifier to become hot enough to cause a minor burn to the skin, and in extreme cases, the possibility of the unit to produce smoke or fire.

The resolution requires an upgrade of 2 transistors, performed by a qualified technician, inside the amplifier module of the subwoofer. If your serial # is within the range noted above, it will require the upgrade.

If your amplifier serial # is within the range noted above, call us immediately. Within one business day we will ship an upgraded amplifier module directly to you at no charge along with a postage-paid return label. After you receive and replace the amplifier module, please put the old amplifier module in the box in which the replacement module was shipped, attach the provided return shipping label to the box, and hand it to any Fed Ex driver or drop it off at any Fed Ex Kinko’s shipping location. Plus, as a courtesy, we will automatically extend the modified amplifier warranty for an additional 1 year.

 

  
Here is how to find the serial number: http://www.parts-express.com/pdf/HT100-120_Amplifier_Procedure.pdf

 

It proves Dayton does not have the necessary simulation & test gear to test their products for extreme conditions. The question remains that if the quality of craftsmanship is so poor, how do you expect them to have good sound quality?

No, it shows that they have the guts to do a recall when they do find a problem.  Like Toyota. 

Many companies are highly reluctant or will not do a recall because of the potential bad publicity it engenders.

Oh, and it also shows your lack of understanding of the difficulties of engineering and manufacturing complex products, especially for small niche-market firms.  Look at the HE-5, for example.

And what quality of craftsmanship do you expect at their prices?  Seriously, find a better built and better sounding new amplifier and set of speakers for under $60...  Oh, not to mention the amp is dual voltage, comes with a Europlug adapter and can run off of 8 AA batteries, on top of sounding as good as any other solid state amp many times its price...

Or need I remind you of Logitech's own recalls... Here's a few I uncovered after about thirty seconds...

Shocking Logitech power adapter recalled

By Grant Shepherd

SYDNEY: Logitech Australia Computer Peripherals has issued a product recall for a power adapter on one of its iPod and iPhone alarm clocks due to a risk of electric shock.

According to the official product recall document, the recall is for the Logitech Pure-Fi AnytimeTM alarm clock iPod/iPhone sold between 1 August 2009 and 10 November 2009 at Big W, JB Hi-Fi, Harvey Norman and The Good Guys.

The identifying products also have date codes of 0924, 0926, 0928, 0928 and 0932.

The reason for the recall is that the plastic housing of the power adapter may come loose and expose the internal circuits. This may in turn pose a risk of electric shock for consumers.

If you purchased this product and the date code matches one shown above, then you have to immediately stop using the product and contact Logitech customer support on 1800 025 544 for a replacement.

Z-2300 sub woofer is quite good, unfortunately there is no option available on the sub-woofer to use it with other brand of speakers, that is there is no rotating switch on the Z-2300 to adjust the low pass frequency.

The sound from the  Z-2300 2 way speakers is veiled, I think it is because of the internal electronics.

My Z-2300 is left unused. I asked for a circuit diagram from the manufacturer to do some design alterations they refused to give to me. Do you have the circuit diagram?

Hi all,

I bought two z2300 systems 3 o 4 years ago. It soudn very nice but with the time all the satellites blew up so I'm looking for a good replacement because the subwoofer and the amp still works!

I have some candidates but these speaker worth it for the z2300 system?

Thank you in advance,

Does anyone know if you can use 6 ohm speakers with the Z-2300 amplifier?

I'm thinking of hooking up some bookshelves to replace the satellites on my z-2300. I know 8ohm speakers work fine, but what about 6 ohm, anyone have any experience?

Measure the D.C. resistance of the speaker with an ohm meter, If it reads 5-6 ohm range it is likely safe as that is what most 8ohm rated speakers will measure. if they measure below 5 ohms I would question the ability to drive it safely especially if playing high volume. Probably ok at low to medium volume but not high volume.

Thanks for the tip. My multimeter is garbage and can't seem to get accurate readings or maybe I'm using it wrong lol. I'll try to get a proper digital multimeter to measure it.

Hi, I have been digging around for a while  now. I'm considering getting a speakers for my pc. I have 3 candidates so far, z2300 (AU$172), A2(AU$229) and Corsair sp2500(AU$250). I was given the impression that z2300 is very good bang for the buck, but from what i ve heard that the vocals are bit muffled on z2300 compare to the other 2 candidate.

Since i will be using the speakers for musics, watching movies and TV shows most of the time, so i figure clarity on the vocal may be important. Therefore i really want to know, given my requirements, what would you guys recommend.

Cheers

Not to thread necro, but personally, I profoundly dislike the Z-2300's, but have never heard your other 2 options. Given my experiences, I'd say go with anything except the z-2300's.

I wholeheartedly agree with the earlier reviewer who called the z-2300's 'fart cannons.' To my unsophisticated ears, they have flabby, inaccurate bass, and veiled mids and highs. Music sounds like it's being farted by a fat man into a half full bathub.

I listen to these Logitechs and the Klipsch ProMedia 2.1's almost daily (my wife has the Promedias), and to my ears the ProMedia's are vastly superior. They lack the over-powered sub, but at least I can discern mids and highs. I've regretted buying the z-2300 pretty much since the first day I received them, but it was too expensive to ship them back to the vendor.

For reference, I mostly listen to music and games on Sennheiser HD580's.

Just my $0.02.
