Speakers for our Car Audio System. is Bigger Better?
You are now considering purchasing new speakers for your car and there are a number of things that should be thought about in order that you make the best choice possible. It is crucial that when looking to purchase speakers for your car you go with a clear idea and plan of what it is you intend to buy. It does not naturally follow that the bigger the speakers the better they are.
In fact you may find that when purchasing your speakers they may cost more than you intended and it is wise not to purchase ones which have numerous features which you won’t actually use. It is sensible to remember that the highest quality audio speakers available for your car will cost more than a lot of others, but in general these are worth the extra cost. However, if you do decide that big speakers are what you want then make sure the ones you purchase have a brand name that can be depended upon and ensure that they will provide you with crystal clear sound at all times.
Today there are 2 kinds of basic car stereo speakers available on the market and these are component or full range speakers. Both have their own pros and cons. However, if you are looking to replace the factory installed speakers already in your car with the minimum of fuss then you should no look no further than full range speakers (consisting of a tweeter and woofer, you may even find some come equipped with a midrange or super tweeter as well). These styles of speakers also come in a varying range of sizes and prices.
But then again as previously discussed if you are looking for bigger car speakers to install then you should be considering a component speaker set. Not only do component speakers give you the best possible sound quality for your money because of their superior design and each component has been specifically designed to complement each other. Certainly big speakers can be a part of any component system as long as you make sure that you have all the necessary components for their installation.
A component system is especially good for those people looking for a serious stereo speaker system for their car. This sound system will not only provide you with greater depth of sound but also a much realistic one as well. The exceptional dynamics and detailed sound provided by such a system is because of the higher standard of materials that have been used which will not normally be found in a full range speaker system.
However, when it comes to which are better, small or big car speakers, this cannot be easily answered. Even if you prefer to install big speakers in your car they will not always provide you with the best sound and you will soon see just how many different shapes and sizes of speakers there are now available. But rather than deciding on big or small speakers for your car it is much wiser to invest in a good quality car audio system instead.

How does impedance relate to sound quality in home audio speakers?
I am in need of new speakers for my new home theater system, however as tech savy as I am, speakers are not my forte. The current speakers I run are 8 Ohm impedance, 150W, 91DB Sound pressure, with 36Hz-22Khz range. These are Onkyo Fusion AVs. I need a good pair of slim line speakers, and I have found a few that I like however I am not sure how they compare with my current set.
Can somone please explain to me which of these statistics should be lower, and which should be higher for optimal sound quality.
Thanks!
You want your speakers to handle your system's output power, so you'll need at least 150W speakers.
The 91 dB sound pressure is an indication of the efficiency of the speakers. Higher is more efficient, lower is less efficient. Remember that dB is logarithmic, so a 3 dB change is a factor of 2 (88 dB uses twice the power to sound as loud as your 91 dB speakers).
A key spec of the frequency range was left out, and that is the variation from one frequency to another -- i.e. +/- 3 dB. Ideally, you'd like +/- 0 dB so all frequencies would sound the same with the same power input, but that's not going to happen, so most spec how close they come to the ideal. A speaker with +/- 0.5 dB across the frequency range will sound far more accurate that one that is +/- 3 dB (remember that 3 dB is a factor of 2).
The wider and flatter (+/- 0dB) the frequency range, the better.
Impedance by itself generally doesn't relate to sound quality; you just need to match your amplifier's preference for best results.
But remember that the specs are the manufacturer's specs, not independently certified specs. You'd do well to consult audio review magazines for their test results of the speakers you're thinking of instead of believing the manufacturer's specs. They aren't perfect, either, but they will probably be more objective than the OEM.

Wheel-inspired style combines with rugged durability in the db grille. Polk Audio's db Series Polk Audio's entire db line of coaxial and component speakers has been redesigned and re-engineered with superior looks and even better sound. Polk has added three new sizes to cover a broader range of vehicle applications. And they've done all that at prices that make high performance affordable to everyone! The db Series works well in OEM factory systems, as well as with high-powered aftermarket head units and component power amps. The db Series delivers classic Polk Audio performance and durability like never before. This is how you turn up the style. The look is about more than performance. It's about making every detail count, from the wiring harness under the hood to the fit and finish of your loudspeaker installs. Even before you fire them up, the db Series delivers. ABS wheel-inspired grilles make a muscular statement about your entire audio system and say you're ready to unleash some real sound. Hidden wire channels give your system a clean, professional look. Now if you'd prefer to be more subtle about your audio system (although why would you?), db makes a comfortable stealth installation and will mount easily behind factory grilles. The db Series fits. Yes, it's just that simple. The last thing Polk wants is to sell you a great speaker that doesn't fit. Our new multi-hole mounting pattern and shallow-depth magnet design have created our highest vehicle application ratio for easy drop-in installations in just about any car on the road (and probably some that should have been taken off the road years ago). Tweeters in the component models can be flush & surface-swivel mounted using the supplied hardware. With db, we've made sure you have maximum install flexibility. High Efficiency Design It means less amplifier power is needed for more audio output. Meaning better sound and more volume using less power. The bottom line is db Loudspeakers will definitely blow you and your friends away, whether they're driven by aftermarket head units or factory installed electronics. Marine Certified Marine Certified means your db loudspeakers will perform reliably on the water as well as they do on land. So Polk attacked every db speaker with a series of punishing real world and accelerated weathering lab tests to see if they could take what some pretty nasty marine and automotive environments could dish out. Polk exposed dbs to hundreds of hours of salt fog, intense ultraviolet light and extreme temperatures from -40 degrees to 185 degrees F (-40 degrees to 85 degrees C). They performed as well after the tests as before (they didn't look so good). No wonder Correct Craft builds Polk Audio speakers into their award-winning Nautiques ski and wakeboarding boats, and Bullet uses Polk db speakers in their marine "tower" speaker enclosures.
