You don't need the biggest woofer, you just need to get horny :xeye:

But seriously, chasing the biggest woofer and the biggest bass is completely pointless, I hope you realise that. I'm guessing you are probably a figment of someone’s imagination actually...

What are you going to do in your Skating Rink when get a null from 10Hz room modes and it cancels out 75% of your incredible bass power??
 
ok guys, well I know I neeed to learn this stuff on my own and I went over some of the basics on making crossovers uF etc etc and I haven't a clue as too what it all means so Could any of you guys give me a hand in designing a croosver for these speakers in this 3 way design:

tweeter

mid woofers


subwoofer/sub bass

the croosver will need to be able to handle around 220 watts rms um as far as ohms and all that it's whatevergoes with you guys.
thanx, I appreciate everyone here alot.

ps: the design is mw/t/mw/sw (midwoofer/tweeter/midwoofer/subwoofer)
 
If you want to be a CEO and Chairman of a future speaker company, it's time to hit the books and get a grounding in basic electronics and acoustics. You can't expect people to do your work for you, but if you ht a block in your own efforts to learn, the forum can be a great resource.
 
I agree, time to get to work.

A three-way crossover is a MAJOR undertaking. If you're serious about such a project, I would be a major advocate of using an active crossover from the subwoofer to the two-way on top. That would greatly simplify matters.

Have you built a project yet? It's time to build something- you'll never get anywhere from just saying "what if?"- you've got to get acquainted with the reality of construction and design!

Go build something, anything. What happened to the BIBB project? I thought that project was pretty much in the bag. If you don't do that project, then go get an established project off of someone's website, or else buy a kit- just go build it! Trust me, you'll learn a lot.
 
yeh your right I am gettin down with the books etc etc and all tha, well I know that Id be stretching it with the tweeter and mid woofer but I got that selection of driver because I already have a cabinet now I just need to fill the cabinet up without draining my wallet plus all the drivers are sheilded so I can place them near my tv which will be a plus in my crowded room where space is VERY limited.
 
ok I got designing a crossover down pat(resistors,caps,inductors,etc,etc,) but now I am stumped as how to put all this together on a pc board a little help with this anybody? I googled for about an hour lookin for how to install the parts on the pc board with little luck cause all I get the layout not how to physically solder the parts on the pc board and where to sodder them and how to connect them.

Excellent news. XO's can be tricky. Glad to hear you've got it.

etch out your pc board but I dont think it's nessacary is it?

Well no, not really. I use a piece of plywood and hot glue. I build it like a harness with the feed and output wires attached.

Hi Punk & Cal,
the pic shows the inductors all facing the same way, up.
There may be interaction between them when done this way.
I note that Cal has given a bit of room between each, but it would be better if the three inductors were oriented at right angles to each other.
If there were four then the two that have to face in the same direction must be the farthest apart.
 
Well, I have - even on the "upright" coil I have noticed a diffence in which way it "points" - anyway, I dont hope he will use that many inductors

Not to offend Punkrk, but I doubt he will notice the difference - but its a good thing he is finally doing something 🙂
 
Coils...

...I was just reading this, Self found the effect was present in an amp where the coils were physically close, but once there was more than a few inches between coils, it was no big deal...orientation, if well controlled reduced the effect a lot.

With a single multichannel PCB for an amp it's hard to achieve the spacing necessary. In a speaker, where the woofer and tweeter sections can trivially be separated, I would think it less problematic.

Andrew,

True enough. I just haven't noticed the difference. I like to mount my coils so they are spaced at least the diameter of the coil apart ie: a 2" diameter coil is at least 2" away from another. I thought placing them on end would apply if the coils are close together. Just my take.

Well the fact that Bose is still a strong player in the market makes me wonder. Mind you, you did say usually. 😉
