First "REAL" loudspeaker project!!!!! please come and see :p

[JinMTVT]

well thank you very much all for the comments!

I agree that it sounds like nothing is going on below 3-400hz
ahhaahhah

i didn't expect a 123hz FS neway

Although there is place on the side baffle for 1-2 4" woofers on each side, this project is already costing twice what it was supposed to ..

and i have seen nowhere of the stupid 78db efficiency
should've gather the info better ...

that is the reason why they sound so quiet!!!

this might be a problem with the akai, as it doesn't like to be driven hard ( lot's of clipping distortion ) and it doesn't send the same power as my 2B for sure


Well, u see, that is why i asked so many times people in here to put up a FAQ for noobs like me with recommendation and what to spot when looking for drivers ... i think that finding good drivers is the problematic of every noob

15Hz is sufficient for this system though ..but he'll need more bass soon ..i shall build him a small woofer thing

would using 1-2 woofers on the side baffle be enough ?
wouldn't it interfer with the tweeters sound ?


All in all, this little system sure plays good mid/highs
ahhaha ..very detailed even at low volume setting
super clear sound..but it lacks dynamics .. maybe just the air volume is not there


i seriously thought that by using multiple drivers of the same size it would help with the low end response.. nah ???

Puis-je suis ton frere? Lucky man, getting speakers and subs for x-mas!


Well, using a lot of small drivers will give you the necessary volume displacement of low-end sound though, the characterstic that will hinder your low-end sound is the fs (free-air resonance frequency). This will determine the driver's natural (w/o active elctronics) sound.

You should add a sub-woofer of some sort, though you will need to make sure you match the levels of the speakers with the woofer. Use an L-pad and SPL meter if you have one. If your spacing is about 1-2 cm. the speakers should be operating as line arrays.

So, efficiency would become 84dB. (still too low for me) and Sensitivity would become 84dB. as well. (Both low.) You already knew that anyway though. If you have any questions on parameters you can search google or the forum--I've mentioned characteristics to be expected under certain conditions. I've learned a lot from reading, but you learn the most when you experiment!


Au-revoir.
