Chorus II


Dustin

Recommended Posts

I just brought this up not too long ago, even called Klipsch parts and they ain't got nothin'. I see the ki-396 uses a k-48-st, not sure what the differences are or if they'd work or if Klipsch would even sell them. If you find out anything let me / us know!

The 15c has an 80oz mag the 48 has a 96 and the usable frequency response in the 15c specs is 63hz and up, would probably "work" but wouldn't consider it a direct replacement. Has anyone tried the 15c in a Chorus? 

 

Exact replacement is just not going to happen unless you buy used or find NOS.

 

Crites woofers would be another option, probably more similar to the K-33 than the K-48.

 

Maybe Klipsch uses a similar driver in their pro gear, won't hurt to give a call.

I have looked at the Eminence Kappa pro lfc before, looks like the closest available driver through their website:

Found this on the interwebs, guy measured a k-48-E and got the numbers:

 

https://forum.speakerplans.com/klipsch-k48-driver-specs_topic82799.html

 

I'm not a techy by any stretch but comparing posted numbers side by side a lot of the values are very close with just a couple being a bit off. I don't know which of these numbers really matter and which ones don't? If I were to try out a new woofer these would probably be it though. 

 

From what I can tell the Chorus cabinets are 4.5 cu ft, it would be interesting to plug the Kappa pro numbers into a box building program and see what kind of frequency response comes out of it?

Isn't that basically a k-33 replacement? 

Yes, to me you don't need a k-48 unless you are doing mindless things or using them in a pro atmosphere.  That is why I stated Home use.

Add some weight to the passive and you'd likely get a nice bump in the bass extension also.

 

More than one way to skin a cat and with a little tweaking, likely come out with something more balanced with better extension.

The K-48 is a tough act to follow.

 

Still very curious to hear the consensus on a suitable replacement.

 

If the Faital Pro 15PR400 is as articulate AND goes lower it’s going to get some exercise in my living room.

The biggest change will be sound pressure, as Faital works with double sound pressure at the same wattage

There are also the 15FH500 and the 15FH510 which are similar and equally interesting..
