JBL s312 UPGRADE POSSIBLE ?????
THANKS TO ALL FOR ALL THE HELP PROVIDED IN THIS FORUM.
I BEEN VERY HAPPY WITH MY JBL S312 STUDIO SERIES....I BEEN GETTING DRUNK ON THEM MANY TIMES.THEY LEFT ME WITH A HAPPY FEELING ALL THE TIME.
I RUN THEM WITH A YAMAHA RX-V1400.....BUT....AFTER LISTENING FOR A FEW YEARS...i WAS FEELING LIKE THEY NEED MORE WATTS PER CHANEL .
I AM WILLING TO TAKE MY CHANCES....
CARS ARE UPGRADEABLE....YOU WANT BETTER WEELS YOU GO AHEAD AND CHANGE YOUR WEELS WITH A BETTER ONES.YOU WANT BETTER BREAKS YOU UPGRADE TO BETTER BREAKS.YOU WANT BETTER SUSPENSION YOU GO AHEAD AND UPGRADE.BUT...YOU STILL HAVE THE SAME CAR...DONT YOU????
CAN THIS CONCEPT BE APPLYED TO A JBL S312 STUDIO SERIES FLOOR STANDING SPEAKERS????????????
WHAT ABOUT BETTER DRIVERS WITH MORE WATTS PER CHANEL ???????
WHAT ABOUT CHANGING THE COILS AND RESISTANCES ON THE CROSSOVERS FOR BETTER FOR BETTER ONES ????
CAN THIS BE DONE?
WOULD THIS UPGRADE BE A GOOD CHOCE?
WOULD I SEE ANY GOOD RESULTS ,IMPROVEMENTS IN SOUND QUALITY AFTER CHANGING FOR BETTER CROSSOVERS AND BETTER DRIVERS????
IF SO......WHAT ARE THE DRIVERS THAT SHOULD I USE ?????
MONEY IS NOT AN ISSUE. THIS IS JUST A PROYECT FOR FUN THAT'S ALL.I AM WILLING TO DEAL WITH THE RESULTS AND I WILL KEEP MY ORIGINAL DRIVERS AND CROSSOVERS JUST IN CASE. THANKS IN ADVANCE.

I wouldn't touch the insides of the speakers unless you are a pro speaker designer. JBL speaker design engineers have probably squeezed every ounce of performance out of the drivers and crossovers that's possible considering the enclosure. If money is no object then the greatest improvement in sound would be upgrading to a higher level speaker from JBL or other brand. I am in no way knocking your JBL's, only saying that usually the way to get the biggest increase in sound quality is in the speakers more so than the amp.
If you definetly keep these speakers then powering them with a new amp might offer some audible advantages. The amp in the Yammy 1400 is very good as far as receivers go. The only porblem would be if you are really cranking them up to very loud volumes. Then you might sometimes be driving the amp in the 1400 into or near clipping (the amp has run out of gas and is distorting in an audible way). The distortion will cause the speaker to sound muddy or loose it defined and clear sound. At high volumes you might also hear a little edginess in the highs. This can be a sign of amp distortion or a natural characteristic that some people hear in the titanium tweeter.
While the JBL is quite efficient (sensitivity ... 92dB's) it also has a fairly high power handling capability. You might benefit with the JBL's by going to a top quality power amp still using the Yammy 1400 as the pre-amp. Here is a company that I bought my new amp from. Emotiva is an electronics company that assembles their products in China and sells them direct to the end user via the internet. These are extremely high quality amps at amazing prices. This is an example of one of their 2 channel amps that is a brute. The power specs are very conservative. This XPA-2 amp would drive your JBL's to their max performance. The UPA-2 would be an upgrade from the Yammy amp but not provide a lot more power. You would pay about 2-3 times this price for a comparable amp from a local dealer.

PS: OK, now I saw your other posts. Only a suggestion, but next time combine your situation into one thread and give all the details in one complete post so we can help you the most. Several suggstions:
.....You can use a 2 channel power amp to run the front left and right (JBL's) and use the Yammy for the other 3 channels if you have a 5.1 system (or the other 5 channels if you have a 7.1 system?).
.....You could use a 5 Channel power amp (like the Emotiva XPA-5, adding a UPA-2 for the rear channels in a 7.1 system) ) and use the Yammy 1400 as a pre-amp and surround processor only.
.....You could use a 7 channel power amp (like the Emotiva UPA-7) and the Yammy as the pre-pro.
.....In the future if you change any speakers try to make sure the three speakers across the front are voice/timbre matched. That means they are from the same brand and series and have at least the same exact tweeter and also mid if possible. This also helps for the surround speakers. Voice/timbre matched speakers allow for the best smooth and homogenous surround sound.
