When things, such as audio, are subjective, there is always a lot of snake oil and BS.

WOW! Absolutely MAJOR props to Ascend Acoustics! I looked at their flagship speaker ($2K) and they have quite a few measurments!! More ID companies should follow this trend!

Yeah...take those blinders off! Ascend has been posting those types of measurements for years!

What is even nicer are the measurements they have for the RAAL tweeter upgrade.

I just emailed them thanking them!

I saw the RAAL upgrade! That looks like one mean speaker! For one nice looking price tag!! I mostly DIY and I'll be buying the Philharmonic 2 when I have enough saved, but I'm strongly considering purchasing that Sierra Ribbon Tower somewhere down the road! They measure very nicely!

And a good looking speaker too!

Not sure if this is a myth, but when it comes to speaker sensitivity. That speaker A with a sensitivity rating of say 95db vs. speaker B with a sensitvity rating of say 87db won't sound as good as speaker A because they are less efficient. I don't claim to be an expert on this subject, but would it really matter how sensitive a speaker is for it to be a 'better' speaker? If said speaker has poor build quality or bad speakers or a cheaply made crossover, wouldn't playing it louder because of a higher sensitvity rating make said speaker sound even worse? Just wondering.

A less sensitive speaker will not sound worse than a very sensitive speaker. It'll just take more power to bring the less sensitive speaker to the same SPL as the more sensitive one!

Every day I learn a little bit more about acoustics, speakers, amps, anything audio related. This is my hobby and I want to know everything about everything! With that said, I want to learn more about drivers. How they work, directivity, matching drivers, picking drivers, ETC. Everything! Do you guys have any links you can provide?

Thanks!

Ah, ok got it thanks. I am aware that an underpowered speaker when driven hard will distort, blow and possibly clip and fry the amp being used to power it.(If played at said volume level for an extended period of time) Was looking for a little clarity on the whole sensitivity ratings issue.

Playing with too few watts can do what you stated.

But an 88db sensitive speaker, will in no way, automatically sound worse than an 84db speaker.

I may be mistating this but I think this is how it works. You have to double the power to increase the sound level 3 dB's. So for speaker B (with a sensitivity rating of 87dB @ 1 watt) to match the output of speaker A (with a sensitivity of 95dB @1 watt) it would need 8 watts of power. That 8 watts pf power would bring it to 96 dB's while it would only take 1 watt of power for speaker A to reach 95 db"s. Do I have that right fellas?

This is correct! You must double the watts to gain 3db. So if I have a speaker that plays 100db at 100watts (i'm not sure a speaker like this exists but math is easy! Lol) I must use 200 watts for the speaker to play at 103db. 400watts for the speaker to play 106db. 800 watts for it to play at 109db! (Thank goodness a speaker like this doesn't exist!)

He was partially correct. High priced toys, low satisfaction, compared to Klipsch. That is low price for High satisfaction. Back in the day, Bose was better, until they came out with their all-in-1 crap systems.

Or links to anything else I can learn that's audio related!

With that much of a difference in sensitivity it's possible. The lower sensitivity speaker will need a much more powerful amp to reach the same levels, and if you don't have adequate power you could be seeing much higher distortion levels from the amp. Higher sensitivity speakers also tend to have much lower distortion than lower sensitivity speakers when driven to the same output levels. If you don't play very loud then it's usually no concern, but if you do a higher sensitivity speaker will probably sound better.

That Yamaha amps "sound" bright!!! Their better equipment could embarass multi-kilobuck stuff as far as measurements are concerned. They way, way underate the power of their two channel amps. I have a vintage Yamaha A-1000 integrated amp and it is a bruiser in every sense of the word! Sounds wonderful and it is built rock solid!

I was wondering about this as I should be getting a pair of B-Stock Ascend CBM-170 SE's next week(placed my order yesterday), to see how they compare to my Athena AS-B1's. They will be powered by a Yahama RX-A700, but I usually don't listen too loud as I have an apartment. My listening levels are around -54db to -60db depending on what I am watching or listening to. Thanks everyone for the info.

You are describing a 79db sensitive speaker and I imagine it's not too far out of the question. I owned the Usher BE-718 before and I believe it's a 83db sensitive speaker.

It's the truth! If you make it clear that HT/audio is a big deal to you, and a part of your life from before you even met her (easier if that last part is true), she'll let you have your own gear.
