Hi teatea, I'll be happy to help where I can.

Sensivity - Expressed in decibels (dB), sensitivity is the measurement of a speaker's "efficiency" (or sound output).

The higher the dB in sensivity the better. It means the speakers are effecient and can take the wattage given to it and turn it into sound. Decent speakers have around 90dB sensivity. Here's an example, I have a 90dB sensitive speaker with 20W amplifier will beat your 60dB sensitive speaker with 100W amplifier in power.

Frequency Response - The human ear is capable of hearing frequencies in the 13.75 Hz to 28 kHz range. (The avg is around 20 Hz to 20 kHz, that's why a lot of headphones output in that range) Most speakers are designed to operate in a specific part of that sound range (bass speakers at the low end, tweeter speakers at the high end). Frequency response is a measurement of the speaker's operating range.

The wider the range the better

Speaker Cone Size - The difference in size between two tweeter cones (or any other like speaker cones) will help determine the quality of the sound you hear. In general, the bigger the cone, the more powerful the speaker, the cleaner the sound.

Power - A speaker's recommended power range should never be less than the maximum power the receiver is capable of producing. Measured in watts, the best audio/video receivers put out 80 or more watts of power. Woofers require the most power. Subwoofers are usually self-powered. What many don't realize, however, is that more power is also the secret to cleaner, more dynamic sound — at any volume.


THX Certification - THX-certified speakers meet the quality-control criteria defined by Lucasfilm, the company formed by George Lucas — creator of the Star Wars and Indiana Jones movies.

Magnetic Shielding - Any speaker within two feet of the TV should include magnetic shielding to prevent interference.

Cross-over frequency - The crossover is a circuit that divides, shapes and allocates the high and low frequencies to different drivers. A crossover is used when a speaker system has more than one driver. It keeps the drivers operating in their most accurate frequency range.



Keep in mind all of this is just numbers. The rest is based on personal preferences. When deciding on speakers, keep in mind what is it being used for (computer games, music, home theater, all) and the environment where the speakers will be placed.

thank u so much scott!!.....really nice post!!!
u just explained everything i want to know

i knew it, TA members always rocks...

I would go with the cerwin's just because the put out more bass and sound better...

hi hi Scottaculous
i got 1 more question

Impedance 4 Ohms/ 8 Ohms <-- whats this?
also about power handling.. some wrote 200w and some wrote 60w(rms)
how to covert those?

Impedance - Parameter used by speaker engineers to characterize how much current the speaker will draw from an amplifier. Low impedance means correspondingly higher current. Impedance is the opposition to current flow in an AC circuit, specified in ohms. Impedance is to an AC signal what resistance is to DC. Impedance differs from resistance in that impedance implies that the load is not a simple resistance, but a combination of resistance, inductive reactance, and capacitive reactance.

Most speakers have 8 ohms.

Power handling - The RMS (Root Mean Square) is usually implied if left out. Power is the product of voltage and current, expressed by Ohm's Law as: Root Mean Square. The equivalent power-producing measure of a waveform. Defined as the square root of the arithmetic average of a set of squared instantaneous values.

got it......~~

thanx again...

pretty much anything good that CV makes is going to be nice... I have thier LS12's (12" woofer 3-way consumer speakers) and they hit hard! plenty of thump for an apartment, they piss the neighbors off continually.

i've used thier products in quite a few applications (home, car, etc) and see thier bassboxes and speakers at clubs all the time - one of the local clubs just added a few of thier bassboxes and wall-mounted loudspeakers and it sounds great - much better than thier old setup.

bottom like, CV is one of my favorite makers or speakers... they seem to be pretty affordable, too!

omg dude...ur crazy!!!! wtf...hes gonna have a club system @ his out :P

lol
how big is your basement? Have you talked to the neighbours yet?

yea.. i think a CE2000 & V253's will cause a neighborhood noise disturbance... or maybe just foundation cracks!

why dont you get one of those CV dryer-sized bass boxes while your at it ?
-mer

Private house, neighbors are pretty far, I would say good 80 feet away from their solid wall side... (no windows)..
Plus my basement has only small windows looking into the ground, so sound should be pretty well Isolated..
I pretty much made my mind.. for my August party - CE4000 and CV V-253s.. I have a huge B&W woofer I will borrow from my Home Theater setup..
thanks for your input guys...

but wouldn't you have way to much power for such a small place (I'm guessing the size of your basement's not that extravagant) how loud are you gonna turn that up
