What makes a subwoofer efficient

[stormwalker100]

rubber is more of sound quality  then spl. but pro audio is beast

[FonZ4590]

thanks for the video man!

Its all a bit more clear now :)

[BSCK94]

Simply brilliant

[TheNickmazz]

that was interesting i have 8 inch scanspeak midbass units which after 10 years or so the foam surrounds started to deteriorate which apparently happens with this material, when i got them reconed i asked the bloke doing the job why the company would use these over rubber especially considering their price and he told me it was to save money, since then ive been under the false impression that natural rubber surrounds were a better proposition not so sure now,

thanks for the video it was great

[tom58c]

@iphonesandipads3 you mean former. but yes a aluminum former dissipates heat faster.

[intheshitter]

Great video mate, subscribed :)

[nickihermosilla]

VERY nice vid!!

[map543211]

hexagonal shaped wire in the coil you get even more turns in the gap although thankfully watts are pretty cheap nowadays so efficiency is not as important as it used to be well unless your designing for a large venue

[MrTpengineer]

Some companies expirimented with oval coils for oval speakers, but it ended up with failure due to the weakness of the longer sides. I've heard about this a long tme ago so I don't remember the source, but yea square coils definatly don't exist.

[MegaMultiX]

...with a normal dustcap on, and then WOW, my camera is fucking stupid! xD

[duhweedman420]

how do i make a 4ohm sub wrap it 4 times?

or for 2ohm 2 times?

am i wrong and if so how do i know if my coil is 2-4-6-8 ohms?

[overclockeador]

I didn't understand a fuck, perhaps because I don't speak english...

[tom58c]

@overclockeador your thumbnail says it all lol

[overclockeador]

@tom58c What do you mean dude?

[PouKileKruha]

love that ''round'' part XD

[4LifeJBL]

Super explained Tom! Thumps up

[Vindaturk]

Damn Tom I really didn't know you had so much depth in the physics of car audio. I could only imagine what you would be doing, if you had a ridiculous budget for your system. It says a lot when you can make awesome videos and not spend a shitload of money when others have to dump THOUSANDS into there products. They do it to get views but most aren't anywhere near as knowledgeable as you are Tom. Good Videos man. I'm glad I found you on here.

[notcen24]

wow,,very well explain,,,very interesting too!!!!!

[edzgarage]

Good explanation Tom. Nice ending lol 

[jonmanch3st3r]

noice mane!!!!!!

[tom58c]

@jonmanch3st3r noice what? LOL, thanks :)

[LupicV2]

thank u really helpfully

[tom58c]

@LupicV2 your welcome :)

[prodigytechus]

@tom58c

Does the voice coil in a loudspeaker have a torsional component?, I mean does it rotate a bit apart from linear motion? or does it have a 100% linear motion only ?

[kennywaco]

you explain all this real good man love the videos.

[tom58c]

@kennywaco thanks, more to come.

[codycrowston]

great video, lol "wow my camera's fuckin stupid"

[tom58c]

@codycrowston lol, it freaks out when something gets in the way and always thinks it has to refocus all the time.

[BlackHondaCivicHatch]

Camera Angles FTMFW!!! lol

One thing i was wondering about the dust caps.. Is the difference in effective cone area come into play at all??

[tom58c]

@BlackHondaCivicHatch not really, but a little. you my find theres a bit less with a parabolic cap.

[TheElJosh]

Great videos man. Can't wait for more like this one. But do you find out what kind winding and gap around the voice coil.

[tom58c]

@TheElJosh If its a proper company they will tell this info but as we know thats not the case most of the time. if you do the competition brand stuff inciminator, dd, dc, Fi, sundown, those kind of things. they are really the same when it comes to what kind of coil they use and what not.

[judeh101]

This explains a lot
