Promedia 4.1 System Repaired/Upgraded

Recommended Posts

An upgraded Klipsch 400 watt 4.1 system.

Prone to failing at 3 known hot spots on the sub panel., I upgraded 2 areas with higher wattage resistors and mounted them up off the circuit boards for better air circulation along with 1 zener. After the upgrades, I see no reason why the panel shouldn't last for years and years now. The sub is powered by using a standard wall outlet. (Most all 4.1 systems sold on eBay are in need of the fix and upgrades)

Advertised as a 400 total watt system with the sub at 160watts and each satellite at 60watts. 110dB SPL, 29Hz - 20kHz.

As far as the Promedia 4.1 system goes, the sub panel has BASH amp circuity and is a hard hitter with dual 6 1/2" woofers which makes them very responsive versus one large woofer. The sub cabinet is ported. The entire system is THX certified (by George Lucas), a very clean sound overall. Out of production, it is now a classic system. The 4 satellite speakers have closed cabinets with 3" woofers and Klipsch 3/4" horn tweeters and are pretty much bullet proof (still used in Promedia 2.1 systems).

The control pod has Volume, Bass and Surround knobs for adjustments along with a headphone output and an auxiliary input mini-jacks (1/8"/3.5mm). This pod controller has a mute button to manually shut off all speakers when using headphones. The system defaults to stereo output only from just the front speakers when the aux jack is engaged with only the volume control available. MP3 player, handhelds, laptops, phones can use the aux input jack or you can use the front female input lead, either way will work.

This sub has (2) brand new 6 1/2" Klipsch factory sub woofers installed, sounds tight like you would expect (same woofer used in the still manufactured Promedia 2.1 systems). Speaker front leads are 9' 6" long, rear leads 19' 6" long, pod-to-sub connection 10' long and the pod controller is attached underneath to one of the satellites.

The system is four channel but does not decode a surround signal, you need a sound card, USB unit, desktop computer, receiver, TV, etc., to do the decoding duties to output surround to the front and rear input mini-jacks. Or you can use a 'Y' to create two rights and two lefts in stereo for a fuller sound absent a surround signal source or use the system in a 2.1 mode.

The clarity of this system (those Klipsch horn highs) add to the separation and staging besides a pounding sub (those BASH amp driven dual woofers) that is meant to be felt and will make you want to set aside your headphones but the headphone jack can drive those too. Leaving the speakers on while wearing your headphones and you will be able to actually feel the bass.

Music, movies,TV, steaming  all sound fantastic even at low levels. Called 'computer speakers' these will easily fill a bedroom with sound or a living room or rec room, two car garage, etc.

Message me here for further details if interested and we can discuss it with photos. For the transaction, a standard PayPal invoice is best and affords both buyer and seller some protections. Free shipping (the sub by itself weighs 17+ lbs). Or maybe you only want the upgraded sub panel or panel and sub, this is possible.

I have a 2.1 and a 5.1 in use. If this is anything like those, it's definitely good stuff!  In fact, worth repairing, like you did, if it breaks. 

 

Many many people want Klipsch to start selling the surround computer speakers again.

Yeah, a lot of 4.1 owners don't realize when their sub panels stop working that they can be repaired.

 

The newly redesigned 2.1 doesn't sound as good as the older model. No telling what the results would be if they tried to redesign the 4.1 or 5.1. Besides, all Promedias were advertised as 'computer speakers' back in the day when desktops computer were everywhere, now adays, not so much.

There is a guy on Ebay who knows this stuff.

I assume he knows about the 4.1 also.

Hi Razzz,

 

My 4.1 stopped making sound and the pod light is out. I found someone local in NYC who works on stereos and home theaters, etc. and is looking at my system and feels the power supply is out. I mentioned that I would email here to see if anyone knew where components could be purchased. So that's question #1. 

 

But I'm also interested in the mods you mention and what's involved. You mention you charge a fee but I wasn't sure if that's for the work, the instructions or both? 

 

I'm trying to figure out what would be best since your mod sounds amazing. Please advise what's involved and if he can do the work with your consultation, or if I need to get the amp and pod board to you? Or????

 

Thanks Razz,

 

Steven

Hey Razz

New to the community but I'm trying to assist my uncle in replacing the two subwoofers in his 4.1 system.  I looked on Parts Express and saw a driver that a few people have used to replace the one in their 2.1 system; rave reviews, some say the replacement sounds better, and it is highly recommended for the 2.1 system.  I noticed you stated the OEM sub for the 2.1 and 4.1 are the same, so could I use the replacement driver at PE in the 4.1 system?
