So I finally got a pair of k1000s. I was using them for the first time out of my amp and I forgot to turn off my sub. It was very interesting. I dont think k1000s need more bass. But it was really nice to get a nice fuller sound out of them. Also, it was really nice to be able to spread the wings full and still be able to get a really great bottom end with an even greater sound stage and actually being able to feel the bass.

Well it has only been my second day with the phones and playing around with the sub. I am not sure if I will keep the set up like this. But for now it is giving me really interesting results.

I know there is another member that does this. So I would love to hear some advice with this set up and hear what you think.

(btw, amp is a RWA sig 30.2 and sub is an omega deep hemp cube. )

Just like adding a sub with speakers. There is a personal preference. I have never been able to integrate a sub with speakers in a way that I would want to keep long term.

For the K-1000s a sub seems like a great idea because they do lack bass for the most part. Not in a big way, but it's not an edition 9 or anything. I use headphones because of the neighbors, etc. - so it would defeat the purpose, but I think there are some who enjoy it that way.

If I recall, there were threads a couple years ago about integrating the K-1000 with subs and speakers. A few searches should turn those up.

I still haven't tried it, but I don't have a sub. Might piece together a servo, however, and it would be interesting to build a K-1000 specific crossover into it.

i've been using my k1000 with a REL subwoofer for a few months now - this subwoofer brand allow the connection to the integrated amp via the speaker outs.

so far so good in getting the bottom to complement the k1000. still playing with the integration of the bass though ...

You have the right sub to do the job. I run Ks with ACI 10" sub. Use the same sub on Omega Compact Hemps. [Unfortunately the deep hemp was announced just after i ordered the ACI. But at some point I hope to upgrade to Anico drivers and Deep Hemp. I also have a Sig 30.2.]

I use the sub the majority of the time when listening to Ks. Without the sub, much of my favorite music lacks the proper foundation.

I run my sub at a low crossover point (around 80Hz), with the volume moderate enough it does not overpower the mids and highs. I usually listen with my back to the sub (or sub right in front of me), to help it feel like it's comming from the center of the soundstage.

For set up, you may want to get a demo disc with a range of frequency tones to help get the right balance.

The sub with Ks is not perfect, and I find the sub/Hemps to be considerably more dynamic and real sounding. But given the choice, I do prefer my Ks served with a nice slice of low-end.

Alwayswantmore, thanks for your response. It seems we have similar tastes. I agree, I would much rather listen to my hemps with sub then my k1000's.

When you use your k1000s with sub, do you open the wings wide or do you keep them close? If I keep the k1000s almost closed, I find it really easy to blend them as you said with a low crossover and moderate gain. But once I go wide, there seems to be a gap from the low to low mids and it is really hard to blend. Once I get some more time I will mess with it some more. But I think as you said, having a frequency cd to play around with it, it would make things a little easier.

I have gone back and forth on the wing thing. I always come back to fully open which IMO improves soundstage and sence of air.

Your source, ICs and musical taste likely will influence your choice for wing position. But for me, I am definately sold on open wings. I keep a ruler by my listening station -- measured from the back of the plastic edges of the driver to headband -- the minimum I go is 2". But usually I listen wide open.

BTW: We both have steep slopes on the x-over. I think mine is 12db / octive. I assume the Deep Hemp is that or even higher. My sub has two crossover points plus phase control. I'm sure you have phase, but likely only one crossover point. For a while I ran my sub with two different settings to more gradually fill the gap between ks and sub. I'd have to look at the sub to know exactly where it's set now.

I should also mention the Moon SDv2 hardwire increased resolution and improved the weight and impact of the bass. So this cable may give my Ks an edge over Ks with a stock cable. I also have two great ICs, and IMO both the Hemps and Ks are very sensitive to changes in upstream equipment.

BTW: I've tried several amps with my Ks, and so far the 30.2 is the best I've used (for my musical tastes).

I will be getting some ALO cable on my k1000s soon. Which I actually tested and compared to the stock cable. The cable does just as you mentioned yours does, better resolution and all around better bass.

Over the weekend I was at canjam and I tested every amp there with the k1000s. The only amp that did just a tad better then the 30.2 was this huge accuphase amp. Everything else was a let down to me and I know alot of people praise some of the amps that I heard with the k1000s.

Does your sub actually have a phase control or is it just a on and off switch like the hemp? I wonder if that would help to have more control of the phase.

Quote:



Yes, 180 degree phase. If you're close to the sub, chances are phase won't matter much.

I thought the Deep Hemp had phase control. By you question I must be wrong.

I'm at home now and peeked at the back of the woofer. My first crossover point is set somewhere around 90 or 100 Hz (the control does not have many markings, so that's just approximate.) The second control is much lower, like around 50.

I've never heard the Deep Hemp, but I have a lot of faith in Louis, so I would still think that the Deep Hemp would be a great match for the Ks.

IMO one of the issues with integrating a sub with the Ks is they just don't have the dynamic range or impact when compared to speakers like the Compact Hemps. So no matter what you do with the adjustments, you will never reach the same level of performance. IMO the trick is to keep the sub set low enough that it helps provide a foundation without overwhelming the mids and highs.

Would anybody be able to help me out on hooking up an Aci Titan XL subwoofer on my Akg K 1000 rig?

There are several ways to integrate the sub into my rig, you can check them out at ACI Force XL & Titan XL Subwoofer Hookup Options.

I believe hookup #2 would suit me best (see attachments).
Vinnie Rossie suggested: "To connect to your sub, you want to use the volume controlled RCA output jacks of the Sig 30 (these are the lower RCA jacks) and connect them to the sub's line-level input jacks.
To connect your K1000s, you need to separate the L+, L-, R+, and R- wires of the K1000s. Then connect them to the speaker posts just like you would for home audio speakers.
Do not use any Y-adapters or high pass filters... this is all garbage ".
infinitesymphony suggested: "It would make more sense to just run two cables from the amp to the subwoofer: one from the Left output to the Left input, one from the Right output to the Right input."

Hi, I have a Force XL, RWA 30.2 and K1000s. Currently I'm running RCA cables off the back of the RWA 30.2 to the XL's line level inputs.

I am interested in trying speaker level inputs, but have not taken time to check with ACI to see if their subs support balanced speaker inputs. [CAUTION: RWA has balanced outputs. For the 30.2 you can only connect speaker level inputs to subs that support balanced amps (i.e. they do not share a common ground). So your choices are:

1.) Use line level inputs
2.) Check with ACI to see if your sub supports balanced speaker level inputs

Please report back on what you find and do. Good luck. Kent

Thanks Kent !
I will post an update asap ..
I will be soon (hope) join you in the Akg K1k heaven

You're welcome! BTW, I followed the link to ACI's site from your earlier post. You definately do NOT want to use option 2 if you have a Sig 30 or Sig 30.2. You will be much better off with the two options I covered above.

...IMO you do not need a crossover for the K1000s because they naturally rolloff an octave or two above 30Hz. IMO, a capacitor in-line with the Ks (to roll off the base), may degrade the sound quality to some degree.

On the otherhand, ACI subs have built in crossovers to roll off highs, so the sub will take care of itself (in terms of filling in just the low frequencies). The trick is to find the right crossover fequency and volume level to make the sub sound natural with the Ks.

ACI supplies good written instructions and a CD designed to help with with set-up and integration. Make sure you have these and you should be able to get favorable results.

There are also computer based programs and microphones that can be used if you want a more scientific approach. For me, I am not willing to spend the cash for this sort of thing, so I do my settings by ear.

Really interesting thread!
I will certainly give it a try in my K1000 rig as soon as the Signature 30.2 arrives.
