Duval Audio -- Now with pics.

[Z3PR]

Does anyone know anything about Duval Audio ??? I've never heard of them before, but that doesn't mean anything. Kind of looking at one of thier 4-channel amps.

50 watts per channel @ 4ohm, and 80 watts per channel at 2 ohm.

Okay, I bought it on Ebay. Best offer thing of $25.00 and the seller accepted. Heck, if I'm not happy with it, $25.00 isn't a big loss.

I sure hope it plays better than a $25 amp for ya man

Let us know how it goes.

I searched Google and this model retails anywhere from $129.99 to $199.99 . Got too love the deals on Ebay. Like I said, if it's a POS, it only cost me $25.00, so no big loss. No built in crossover, so I'm going too run a crossover/signal processor inline before it. Limit the freq range going into each channel to what my speakers are designed for. I'm no stereo guru, but I'm thinking that should work.

Got my DUVAL Audio Systems SR-325 (4-channel amp 80watts RMS per channel at 2 ohm) today. Now it'll sit on the top of my desk for a couple of months till I get the Infinity Kappa 6X9's (3-way) for the rear deck.

OOOPpppsssssss, just relized my Infinity Kappa's are 2 ohm speakers, so acording too the manual, this amp does 80 watts RMS per channel at 2 ohm . I can deal with that, LOL. So this sounds a little better. And yes, the 3-way Infinity Kappa 6X9's I'm getting for the rear deck are also 2 ohm speakers.

Here's some pics of my DUVAL 4 channel amp.

New in box, took it out of plastic too take pics.

Guess I better order this next.

Something to keep in mind when you buy an "unknown" amplifier is the fuse rating. An amplifier can't create something from nothing. It's good to see you got it though, let us know how it works.

Like I said, it'll sit on top of the desk for awhile. I'll full read the manual before hooking it up. It calls for a 4 gauge wiring kit, so that's what'll use.

Haven't even hooked it up yet, and I'm already thinking about upgrading to a PHOENIX GOLD OCTANE-R R5.0:4 . Think I might be happier with a Phoenix Gold.

CarDomain Overview

Designed and engineered by the same crazies that brought you the other Phoenix Gold amplifiers, the new Octane-R series offers quality and performance at prices that won't take a huge bite out of your wallet! The Octane-R features a striking black anodized heavy-duty heat sink with a grained aluminum insert and an LED backlit carbon fiber badge. The Octane-R series has all the features you would expect in a high-end amp: Continuously variable crossover, Twin "T" bass boost, and 1 ohm stability. A Remote Monitoring Display (RMD) port allows the addition of an optional voltage monitor, allowing you to keep an eye on how much juice is being delivered to the amp. You can even customize your new Octane-R amplifier with an optional neon lighting kit. Octane-R amps provide all the high-octane power your speakers can handle.

Features:

* Grained aluminum insert with carbon fiber badge
* Blue LED backlit PG logo
* Independent front and rear adjustable input sensitivity controls
* Adjustable 0 – 15 dB Twin "T" 45Hz bass boost

* Signal to Noise Ratio: >100 dB

I wonder why they won't give the THD?

SNR 100db is a nice efficiency, should drive those Kappas nice, so long as its THD isnt crappy? Which dosent seem likely with a 100db efficiency. But I could be and probably am wrong :-)

Think the Duval will become a stocking stuffer for a friend this Christmas.

Found at another site.

THD at Rated RMS Power 1 %

Found at another site. THD at Rated RMS Power 1 %

That would explain why the one site put n/a. Bid cheap

1% is acceptable for a class D sub amp, but it seems to me that based on what you have bought already your looking for fairly high quality, and if thats the case maybe you need to just use the Duval till you can get the scratch together for a class A, 4 channel amp, with a +100db SNR and a 0.1% or lower thd.

Again, I could be completely wrong and probably am

OOPPss, that was suposta be 0.1% not 1%. My bad.
