4" custom subwoofer, 1st build now working with video!!

[secondtimelucky]

As above really, i need some powerfull 4" bass cones for a project im working on, whats out there??? and how much???

Links would be great

[roley]

thought you had a stash of 4 and 6 in comes

[Nay]

Why do you want a 4" bass woofer?

[roley]

its for a dodgy project on a lump of jap crap

[Nay]

fair play. Sound systems compliment jap crap. Technological toys, thats all they are.

[roley]

this is a home made lump of jap crap i have seen the pictures

[Ziggy]

4"?! 5.25 is a challenge, but I'll be shocked when I hear any worthwhile bass out of a 4" speaker. Will probably happen though!

Martyn, what are you going on about now mate??? I think working nights is starting to take its toll on your brain

[secondtimelucky]

Well iv got a prototype made aready, with a crappy 15w cone and its dropping to between 40 and 50hz 87db sensitive

[sati]

there are many , mostly used in studio's monitors or sum desent book shelf speakers. if you can still find a set of LONGMILL mid-bass speakers they are pretty good. if you make an box for the speakers then they will give sum bass. why not try tv spares shop as sum rear projection tvs have 4" bassy speakers which run in free air and sound fairly good.

[secondtimelucky]

As above sati, iv already made a prototype for my design with a 15w rms bass cone, it works down to around 40hz at -6db, but the stereo and speakers its being designed for is 70w rms/channel, so i need something alot more beefy il have to have a look around some of the second hand hifi shops here, iirc some older wharfedale speakers were pretty pokey lol

[sati]

and jambo maybe B&W ?

[miniblob]

JBL's??? Try looking around for non car audio stuff!!

Can you box them in, or do they have a specific enclosure to go in??

The JBL control 1's i use have 4" bass cones i think (may even be 3.5" in the older models?) - they are small and ported and can kick out quite a lot of bass when set up well!! They play quite deep too!!!!
Everyone comments how good they are and thinks there is a little sub somewhere!!
Only about £50 a pair too, so you could buy them and cannibalise them!!!

B&W use cones made by Tang Band i believe!!!
Just looked on their site and they appear to do a 3" square sub - and even a 2" sub!!!!!!!!!! No idea how good that is, but i want some!!!!!
Clicky for TB
I have some of their 5" subs knocking about, but i fancy trying some of those 2" ones!!!!!!!!!!!!

[sati]

lol , 2" bass speaker well thats a frist! , well any speaker in encloser will sound good. to point of course.

[secondtimelucky]

Sod the 2", check this out... http://www.tb-speaker.com/detail/1208_03/w8q-1071f.htm 8x12" sub

[sati]

lol , there was a panel sub and the cone was made from 12mm mdf ,lol and to can forget inchs there talking feet here ,lol

[dips346]

focal Utopia

[sati]

wat about these mid bass drivers:

as above focal Utopia 3w2 50watts rms , manual shows test down 20hz!

HiVi B4N 4" 25watts rms , drops to 50hz

Tang Band W4-656SC 45watts rms , drops to 65hz

Visaton - TI 100 40watts rms, around 50hz

[secondtimelucky]

Dont suppose anyone has a link for the focals??? with pics + tech specs

[Morat]

So, could I use something like a 4" sub in the speaker pods on my touring? I'm going for components in the front.. a sub or two in the back would really finish it off.

Any good??
4.5" woofers

[Morat]

I guess I'll just have to find out.. I appear to have bought them without realising

[sati]

4.5" subs? 5.25" or 4" and they will be MID- BASS drivers.

[secondtimelucky]

Well, iv given up in my search for power in a 4"cone, gonna make my own Got some pioneer 6" bass pump cones lying around and they have plastic baskets, also a pair of decent ish 4" cones with plastic baskets too (can you tell where this is going???) cut cone/basket/magnet assemblies out of each speaker and plastic weld the two halves of each together with modded cone suspension, anyone seen a 100w/RMS 4" sub before??? should be fun

[roley]

go for it mate you know you want to

[secondtimelucky]

Hell yeah, been on the JD and coke though so il probably forget in the morning why do i come up with these ideas when im half cut lol

Hows work doing? Any jobs going back there yet?

[roley]

not a chance bud struggling to keep my job

[secondtimelucky]

Doh, you and me both then shame as im only over the road...close enough to come and annoy you every now and then oh well, new year soon, time for a fresh start methinks

[roley]

you could be right if you make these subs i could be intrested for the touring

[secondtimelucky]

Dont even get that idea in your head il only be making one, possibly two. Chances of finding the bits to do more are slim to non existant might just make one and make it dual coil, 200w/rms 4"er

[roley]

go one make 2 sets i have some ideas springing to mind will tell you morewhen you get back

[secondtimelucky]

tell you what, you find the bits and il make em for ya, hows that sound?? as long as they got plastic baskets it should work

[roley]

ok mate will meet up when you get back to blighty if i dont speak to before have a good new year mate

[secondtimelucky]

You too bud, see you soon

[secondtimelucky]

The 4" sub lives!!!! 100w/rms 6ohm, now all i need to do is finish the rubber surround and figure out how to post 3gp videos

ps its got nearly an inch of excursion

[miniblob]

Will be interested to see how these came out - and if they make a sound worth hearing!!!! Lol!!!!

Good on ya for putting the effort in too!!!!!
