Trying to put a home theater together. These speakers would be used as surrounds (4 of them to be exact) for a 7.2 system. Without knowing the brand and just based on the specifications provided which one of these in-wall speakers would be better. This will be a dedicated home theater.


SPEAKER A:

2-WAY (6.5 Inch Cast Frame Aluminum Cone Woofer & 1 inch Pure Titanium Tweeter)

Frequency Range (-6dB): 30Hz - 30kHz
Recommended Amplifier Power Range:10 - 135 Watts
Sensitivity (2.83V @ 1 meter): 89dB
Nominal Impedance: 8 Ohms Crossover
Frequency: 3,000 Hz; 24 dB/Octave


SPEAKER B:

2-WAY (6.5 Inch Cast Basket Bass - Mid Range Driver Woofer & 1" Pure Aluminum Tweeter

Frequency Range: 28Hz - 30kHz
Recommended Amplifier Power Range:10 - 200 Watts
Sensitivity: 89dB
Nominal Impedance: 8 Ohms Crossover

Those specs don't tell you much of anything, you will never be able to tell which speaker is "better" based on these kind of specs.

You're missing the "(+/- X dB)" on speaker B. One thing to look at is how flat the tone curve is (refers to how accurately it reproduces sound).

+/-6dB on speaker A is a bit of a joke....should be 3dB max when talking specs.

those specs are so similar you wont be able to tell which is better.

Use your ears. What are you main 3 speakers? Try to get something that will be a timbre match if possible.

Not enough info to tell if either speaker is any good. Using -6db is not very good. Power handling is not very high and you do not know if the sensitivity is an in room measurement. Also no f3 spec on the second speaker. For HT use, I would not use either.

Good point--missed that on the first read. The best speakers *for you* will be the ones with the same tweeter as your mains....

Neither one of those speakers are going to hit 30hz at 89 db sensitivity, so the specs are completely false like most commercial speakers. They mean nothing. 3khz is also to high of a x-over point for a 6.5" woofer, so that speaker wont have very good off axis response.

There are very few 6.5" drivers that can do 28 or 30 Hz with any authority. They may be down 3 to 6 dB at 75 dB, but try to get 90 to 95 dB out of them and they'll be down a lot more than that.

They're both 89 dB sensitivity and they have similar power handling, (200 watts is only about 1.5 dB louder than 135 watts.)

The spec's don't state whether the speakers are sealed or ported.

What does "Nominal Impedance: 8 Ohms Crossover" mean? That is nonsensical. Did you transcribe the specs incorrectly?

PS. Instead of trying to be secretive, why not just tell us what speakers these are. We may have some more specific comments if we know the speakers.

If you've already picked your front soundstage I would go with the largest that is recommended by the MFG because most companies make their HT systems work as a package and are timbre and/or voice-matched....

That being said, look up the Owner's thread of the speakers you are considering and see what others are using: http://www.avsforum.com/t/1347531/owners-threads

Measured SPL charts. Without them specs mean little to nothing.
