New speaker project

[Dingdong]

For some reason I bought these cabs on ebay the other day. Seemed like a good idea at the time.





They are not in bad nick. They seem to be solid cherry. Some of the joints are a bit diy, but they will do for my first go at building speakers.
This will be a long term project as funds allow.

I've got a whole bunch of ideas as to what drivers to go for.
The simplest being that I use the tweeters out of a spare pair of DM2's as I like the sound and add a mid and a big, f**k off, woofer in the side.

Any other ideas or suggestions are greatly welcomed. I've got a fair bit of learning to do.

Are they a sealed box or is there a reflex port somewhere? Sealed will be easier imho as you'll have a wider choice of drivers which i believe may well be 12" for bass?

What are the precise internal dimensions? Just remember all that enclosure is for the bass unit

[Dingdong]

Internally they are 20x35x87cm. There is a port at the top and a hole for the connections at the bottom. I have the ports and connections.

[Reid Malenfant]

60.9L with no drivers or port fitted... Bass driver will eat up a bit & so will a port.

What size is the cutout for the bass/mid? The bass driver on the side is only going to be good for up to a maximum of 150Hz or you'll have serious integration problems, even if you went active

[Dingdong]

There is no baffle for the front. I'll have to make my own up.
I think active may be the way to go.

[Reid Malenfant]

Oh, while i think about it, what is the diameter of the port... You see i need to know how low that enclosure can be tuned & you need to leave at least one diameter of the port between the port itself & the back of the enclosure...

More is preferable

Ah, so that hole could be utilised as a bunch of input connections & you could have a sealed box... Or is there another hole to be filled?

Just asking

[Dingdong]

If you look at the 2nd photo. The port is the hole at the top. The id of the port that came with it is 65mm.

[Reid Malenfant]

65mm, cheers Mark.. Yes i now see where the inputs are located, in a rectangular slot... Way down low

[Dingdong]

It should be possible to find the right mid that crosses over around 100hz and 3khz.
As for tweeters. It not necessary to use the Celestion HF1300 and Coles 4001's that I have now. It's just that I have some and I quite like the way they sound.
