Are Joe's cabinets "ported"?

I don't really think it's an absolutely neccessary step in building a cabinet but I believe that Joe's 4x12's are ported.  Good luck on your cab, I'm sure it'll sound great with the EV's in there!

Thanks for the replies, I have asked a few questions on another forum and a guy from Catagory 5 has replied, so I have now asked him about the ports. He said they build Joe's cab's now specifically for the EV speakers. Although when I saw him at Gateshead the other night he was using Van Weeldan cabs, maybe the cat5 is the us rig...

If I get a reply from Cat5 I'll let any other people interested know!

the cat 5 cabs are not ported, but the section that uses the Van Weelden on his new cabs is ..only that section.. Makes a difference.  Id port it and make it switchable between.. it just depends on taste.. I know rick and bogie get a good blast now when I kick on the Twinkleland..

I guess its more round and spread out for the said reasons..  again its taste and not fact.. I once responded to a fan who tried to get into a discussion about the differences on batteries in pedals like Eric Johnson can discern.. I said to him its a taste thing and shouldn't we be out talking to the cute girls in the lobby? This is kind of the same thing.. Ported vs not .. not much of a difference.  Its taste.. a good amp gets past that either way..

I'm just guessing but it seems the easiest way to separate the ported section from the non ported would be to use a solid vertical divider between the 12's and separate inputs on the back for the respective heads.
That way there wouldn't be any overlap from the two sets of speakers, the ported side wouldn't be affected by the non ported.

Just a guess but if Joe says that Rick and Bogie get a blast from the ported cab it's posibly rear ported - they generally stand/sit level or slightly behind Joe's rig. This may mean that it's a semi open back. I've got a Matamp 2x12 cab see this link http://www.matamp.co.uk/cabs212.htm It's the angle one.

The back is split into thirds - the bottom third is part of the cab and includes the Jack sockets - the middle and top thirds are removable. In effect you can run the cab as a closed back or semi open back by leaving the middle panel out.  The down side of open backs in my opinion is that they are more sensitive to position if you put them near a wall - not a problem for Joe but at home or even small venues it's a consideration.

A lot of commercial cabs are too small in my opinion sometimes I think the design dimensions are more about using an 8'x4' sheet without any waste rather than the sound.  It's a lot of work to build a cab and if you want it covered with handles and speaker cloth it starts to mount in cost. On the other hand it is fun and you can get what you want.

If you want some photos of the Matamp back let me know.

Good luck

Where do people buy their EV speakers in the UK? Only place I can find that sells them is commsandsound.com and thomann.de
