Hi all,

I "sort of get" some of the numbers a specs on amplifiers and speakers. BUt I lack the knowledge to understand how they all work together or what constitutes a "good" piece of equipment.

Does anyone know of a decent "layman's terms" site that explains the meanings of the numbers and how they relate to real world use?

Or how to properly select your components so that they work well together to give a decent SQ setup?

I've looked at the FAQ's, and unless I missed something, they were of little use with regards to this.

For example, here's the spec list for an amp I'm using now (I know it's not a high end one, I've only got so much money to through around right now):

Pioneer GM 6200F

CEA 2006 Specifications

Output Power (4 Ohm, <=1% THD) 60 Watts x 4

Output Power (4 Ohm Bridged, <=1% THD) 150 Watts x 2

Output Power (2 Ohm, <=1% THD) 75 Watts x 4

Signal to Noise (1 Watt into 4 Ohms) 80dBA

Dynamic Power (4 Ohm) 60W

Peak Music Power 600 Watts

Number of Channels 4

Load Impedance Capability 2~8 Ohm (Stereo)

4~8 Ohm (Bridged)

Continuous Power (4 ohm) 60W x 4

Continuous Power (2 ohm) 75W x 4

Continuous Power Bridged (4 ohm) 150W x 2

Frequency Response 10Hz ~ 50kHz

Total Harmonic Distortion 0.010%

Signal-to-Noise Ratio >95dB

Dimensions 11-13/16" x 2-3/8" x 13-1/4"

Features

Bridgeable

Channel # Capability 2/3/4

PWM Regulated MOSFET Power Supply

Compression-Type Speaker Terminals

Balanced Isolator Input Circuit

RCA Inputs 4 Channel

RCA Outputs (Pass Thru)

Speaker Level Input 4 Channel

Input Level Control Hi-Volt (400mV ~ 6.5v)

Built-in Crossover LPF/HPF (Front/Rear Independent)

Crossover Frequency Range 80Hz, -12dB/Oct.

Other than knowing that the RMS wattage is the only real number for the power (seems most people agree peak is for marketing purposes) I don't really understand the numbers.

Here's a pair of components I have:

MB Quart dsg 216

TECHNICAL DATA

Power Handling: 50 - 120 W

Frequency Response: 45 - 32.000 Hz

Impedance: 4 Ohms

Crossover Frequency: 5.200 Hz

Sensitivity: 87 dB (1W/1m)

FEATURES

0.75“ (19 mm) tweeters with titanium dome and neodymium magnet system in plastic housing

Woofers with two-piece plastic chassis, red polypropylene cone with edge wound voice coils

Other than trying to match the rms ratings, I'm kinda lost with regards to how the amps and speakers should be selected for each other (altough I do understand the amp should be powerful enough to prevent clipping and adjusted properly).

Oh, in case soemone wants to know, I'm running and audigy 4 with kx drivers (still trying to figure that out well enough) and the aformetioned 6.5's and a single 12" sub. No other processesing of the signal is done other than what comes out of the "as downloaded" kxdriver.

Thanks from someone who wants SQ but doesn't have a lot of cash to spend on it.............
