Which speakers -- have you cleaned up the networks?

KP 2500 which is the same network as a KP 250.  They've been recapped with Audyns.  The H2s I did with Audyns turned out great.  These are really squawker strong.  I taped off the tweeters and then the squawker to find the offending drivers and it seems to be the mids.

I'm guess the KP-250 uses a different driver?

 

I do everything the hard way. I would probably replace the autotransformers, and rescale the primary cap value - rebalancing the network to suit my personal taste.

What's the first sentence in this thread Deano?

 

Here's the network.

The crossovers were certainly different.  I think the mid drivers are the same?   Would need to look it up.

Edit.  The mid drivers are the same.

Yes, you are reading that correctly.

Thanks Jim, that really explains a lot.  7dB is almost twice as loud.  It's no wonder the mids seem overbearing.  I wonder why they did that?

 

Instead of reworking the crossovers, I just ordered L-pads.

And a yea 7 dB.... you could prolly hear that

The whole thing makes no sense to me.  I think the 250 and H2 share the same drivers other than the stouter woofer.  The H2 sounds so much more balanced and the 250 is so mid heavy (for my ears at least).

Well, the 250 was engineered for a much higher output than the consumer H2, so it does make sense to me that it is configured that way.

It makes sense that it needs more power handling but not more mids in relation to lows and highs (in my mind anyways).  In any event, I'm hoping the L-pads will fix me up.

It looks to me like thee KP-250 is voiced like the HIP, very bright for outdoor use.  The tweeter should be pretty hot, too. 

 

While you're in there, why don't you wrap the horns with Dynamat or equal.

Probably the speaker to compare the KP-250 to is the HIP instead of the H2.  The HIP also just attenuates the midrange by 3 db.  In every case, I would think Klipsch attenuated the mid to match the output of the woofer.

You're right but the only reason I compared the two is that I had them both and they seem to use the same squawker and tweeter yet sounded so much different from each another.
