I saw!
Maybe F5T V2 or 3 next huh?
I'm holding fire regards amps.........sending you a pm right now.

Time for an update:
After a week of fiddlin 'n' fussin, I've reached the conclusion that the EmKen enclosure is good.
The 12Lta does all the dynamic, image throwing well.......
But it has a certain hardness to its reproduction that makes it fatiguing.
Our friend JKRO has said he will see if his man will make me a pair of phase plugs, my next step is to seriously look into things like 'pluffing my wizzers', EnAble and shouting back at them with choice North of England colloquialisms.

Hi sippy,

Are you using a circuit to deal with baffle step? I ask because you say fatiguing.

sippy · 1st October 2012, 09:57 AM

Hello rjbond3rd,
The concise answer to that Q is no.
I shall have to do some reading up on the subject.

Is baffle step an issue with an enclosure of this size?
Explain if able, i thought it was a concern with tall narrow enclosures and small drivers.

sippy · 2nd October 2012, 12:56 AM

Its a concern with all drivers as far as I know. Emken might be a big box, just remember the size of the drive unit.
I dont know what the sound of the 'step' should / does sound like, no one seems to describe it just 'you will need it'.
Am waiting till I get phase plugs and see what that change does first, will start getting the stuff together for basket damping as well.

If with every thing sorted out and the extra braces they sound good and i can live with them, I will invest the money and build again with BB ply - if these don't start to rattle I may finish this pair.
These are big boxes, don't kid yerself, due to the 45deg bevel on the front, they appear to be smaller than they are and in my room, backed against the wall, they don't intrude too much more than my out-going boxes.
*just finished gaming - the Lta's don't throw the right image - a second pair of LTA's will be ordered shortly........... which will give me something to listen to when these get treatment.....which is bound to happen.

What would be considered reasonable for a 5'x5'.

What part of the world are you in Etocynned?
Here in England we mostly deal in 8ft x 4ft - I find BBply a few days ago...... £92 a sheet
OUCH!
The WBP I bought was £40 a sheet.
You need 2x 8x4 sheets for EmKen, I think somewhere in this thread it says you need 5 x 5ftx5ft per enclosure.
How loud can you shout OUCH?

Hi sippy, if the speaker sounds balanced when pushed against the wall, but then sounds bass-shy (and thus fatiguing, too bright) when pulled out into the room, that would be one example.

sippy · 2nd October 2012, 04:49 PM

I've had them pulled off the wall by 18 inches this afternoon and no change in the bass.
They only sound bright if one is mad enough to toe them in.
While they were off the walls I put more stuffing in them, now all internal surfaces are treated, some of the surfaces have a layer of very thick and expensive real wool Wilton under the felt. One thought I did have was that my felt is not dense enough and maybe there are reflections through the vents and back through the 'Round Window' (English peeps older than 35 years old will get the pun), so I shall be putting absorbent material on the inside of the basket legs when I pull them out this weekend for basket damping - I found Decorators Caulk for £1/$0.60 a tube while looking for a gouge chisel in the home improvement dept of a local discount shop.
If we get fine weather this weekend, they will have the vent extensions and cross braces glued in, more felted surfaces might help matters.
11 days of EmKen and I'm still liking what I hear so far.
Not missing not having a tweeter either!
