kharma 3.2 & sub...

Cheers Guys.....
maybe ill try to audition it so i can have an opinion for myself.....
i think thats the way to go....!!!!!!the problem is that its quite difficult here in Greece as i think only one exists.....ill see what i can do to convince my dealer to go to that guys house or something......by the way that guy has 5.1 hometheater with kharma's i think the 2's.....

I too heard the Kharma sub,at HE 2005.Sorry,but it was NOT seamless.I heard it on two different days.If you ever heard the magical Lamm 2.1 drive this speaker,in a really good room/set-up,I'd find it hard to believe any "music lover" could feel the sub was an improvement.Just my opinion,and remember these companies want to sell product.BTW,I have heard the sub on the Midi Ex,and the result was the same,to me.Maybe it is only my own perspective,so my thoughts should be taken lightly.

Best!

Twilo: I guess we just feel differently, but it does not work for my ears nor those I know have tried it.

The sub did not add to the sonics in any positive way when I heard it.

Just an FYI on this thread,

I am quite certain that all the users with bad results with the sub, tried to splice it on too the 3.2 without cutting the low frequencies to the 3.2. (splicing= trying to get the sub woofer to match the 3.2's without contouring the 3.2 's low frequency response and simply bumping the subwoofers output into the 3.2's bass extension)

Incase its not already clear, that isn't going to work. I didn't realise (couldn't belive it really) that this is what people were talking about.

hopefully it is quite obvious that this is the wrong way to add a subwoofer to a ported two way speaker.

You need to cut the 3.2 off at about 70hz (+/- 10hz) depending on room and woofer placement (preferrably 2 subs and not left and right----mono subs.)

Once you do this stuff the port of the 3.2 with some socks? this will help the speaker a great deal and give you a complementary rolloff from the speaker to help keep deep bass from the 3.2 and improve its linearity under high output conditions.

Now this has increased the somewhat restricted dynamic output of the 3.2 by 10 fold. and now the sub can work over a wider bandwidth blending seemlessly with the K3.2 Satellites, room interaction will dictate the slopes, but bessel low Q filters are the best for being transparent but they can be more difficult to blend. Most of these following crossovers are very flexible and offer an almost overwhelming amount of solutions.

Crossovers from XTA (digital in digital out)
Lake Technology
or if your on a budget BSS Audio all work well.
Some people like DEQX also

The onboard EQ's can allow room correction and TIME ALIGNMENT with the woofers. Time alignment is more critical than almost any other setup parameter.

There's a little more to it, like sub selection but a speaker like the 3.2 is a minor challenge to add a subwoofer too because it simply does not play that loud. So you likely won't need a $10K subwoofer. Maybe 2 $2500 ones.
