Default Looking to build some big 3 way's Need some help deciding on the woofer.

I've come to a conclusion that I don't like subwoofers. I want a full range loudspeaker array not partially fullrange then the sub elsewhere! So for my next project I want to build a hefty 3 way pair of speakers, about 500Wrms each for my large front room.

So far I half decided on these for the mid and tweet but can't decide what to get in the way of a woofer, I want 10" and about 200Wrms.

Morel CAM 558 2-1/8" Soft Dome Midrange

Morel CAT 408 1-1/8" Compact Soft Dome Tweeter


The thing is because I live in the UK I'm not going to be buying the speakers at different times nor from different shops in the US; I don't want to be hit with import duty and the rest twice. So the driver either needs to be from parts-express or for the UK and needs to not cost anymore than 75 each.

And please anymore input would be great thanks!

Thanks
Boscoe

In my humble opinion, a single 10" does not a hefty woofer make, especially since you mentioned a large front room. At minimum a pair of 10's per side. Fortunately, PE has it's version of a 10" pro driver on sale right now, and still comes in under your $118/ per side

Okay thanks.

What's peoples opinion on a vented or closed cabinet. I prefer the neater nicer bass from a closed cabinet than the louder bass from a vented system, I also find that a closed cabinet is far easier to make!

hey, with your budget its far too expencive to buy from PE, or any other "over there"

Look up Blue Aran
Its located in UK
or Europe Audio

a nice 5" might be a good start
could be ScanSpeak Discovery 15M midrange
and a 12" woofer, sure thing
theres a cheap one in Beyma Studio series
Vifa XT19 tweeter is ok

you will need pro drivers if you want it tougher than that
but 500watt ? I sure wouldnt like to be there

if you want it that loud, I made the plans for this, a while back
I dont know how it will work
but it will be loud allright

Hi,

Your Search Results | CPC

There's usually some good drivers there. Delivery is free over a certain amount. They sell plenty of Celestion, Eminence, PD and Visaton stuff. There's also some matches with MCM, so it can pay to have that open seperately, see what you're looking at.
The guys there are really helpful, they respond to e-mails pretty quickly, and have sets of T/S parameters for most of the drivers they sell.

HTH
Chris

The suggestion by tinitus to switch to the 5" SS Discovery midrange is a good one...a 10-12" playing cleanly high enough for a 2" mid is a rare bird (think Seas W26).

The Peerless 830668 & 830669 are good woofers, relatively inexpensive, and will play high enough to mate well with the 5" Discovery in a system with good overall sensitivity. I would stay with your preference for a larger tweeter to better match directivity at XO.

That driver won't play low enough to be in a "full range" system. A pair per side is louder but not lower.

A nice woofer for a 3 way loud speaker is a 12". That is also the reason to build a multi way.
200watt isn't a design goal a maximum spl is.

Dayton has nice price 10" and 12" with black aluminium cone heavy alu frame. 4 ohm. good for closed loudspeakers

Hi Boscoe,

Zaph has done a big 3 ways in a closed cabinet. The kit at Madisound store.
This kit is fully documented and will work without any problem.

Cheers.
