HWO 89T998/9

I have these Heresy speakers. Running through a mid 90's HK, and an old school sherwood 200 watt amp. I use this set up only for analog audio. Is there a replacement 12 inch woofer for this model. They have like zero bass response?

Welcome to the forum.

You'll find little improvement changing woofs. Placement is critical. Keeping them close to the floor and corners help. Many use a sub with them and many use tube amplification to boost the bass. I personally have found tubes to "wake the bass" and corners help. I'm sure that as many pairs of Heresys as there are someone has come up with a magic cure for the bass on the Heresys.

[:^)] O.K. now I am confused. I thought the Heritage line was the end all be all of Klipsch and now you tell me the Heresys need a magic cure! Hell my RF-5s produce nice base just about anywhere. [*-)]

I'm not trying to start the debate between tube and solid state again but IMHO tubes are THE way to go with the Heritage line. I haven't used my Heresys in a while but when I do it is ONLY with tubes. It brings out the bass quite nicely and tones down the horns which I MYSELF find a bit overpowering in the Heresy. MY taste only ALL and don't get the panties in an uproar. I've found the tubes match extremely well with the Heresy.

To me, the Heritage IS the only speaker line I like enough to keep. I like the Cornwall best. Everyone has their personal preference. I build my systems around my speakers. After all, they are about the most critical part of the system. It all has to work together as a unit. Some pieces just don't match up well. No matter what brand it is.

Synergy between components helps a lot. If you are using a thin sounding amp/receiver, then you'll perceive the heresys to be base shy. Find an amp/receiver that is heavy on the bass side. My Denon makes a ton of bass, but I had a Yamaha that did not.

There
is NO replacement woofer that will give more, or , especially deeper
bass. You need a subwoofer for that. Set the crossover to
about 100 Hz.

That said, those look like 1979 models. If they are, try this as an experiment.

The
squawker is run at 98 db, the tweeter at 99 dB and the woofer runs 94
to 95 dB. This mod drops the tweeter and squawker 3 dB and makes
it sound a lot like a La Scala. It is also flatter. The
change is pretty easy to reverse if you don't like it. The
impedance above 700 Hz is worse than crazy (stock is crazy high,
>110 ohms) and it will affect the frequency response of a lot of
tube amps. If you like it the nest post is the better permanent
design. I run the permanent design in most of my Heresies.

[JohnA]

Here is the permanent design. It will present a nearly flat 11
ohm impedance all across the audio band. That should be very good
for the performance of your tube amp. Be sure the 11 ohm
resistor, or resistors has a total power rating of 20 watts or more and
that it does not touch anything when you're done. It will get hot
at high power.

If
your caps are still the original oil-filled motor start caps, replace
them. They are old and do not perform well at theiur age. I
favor Hovlands but also use the cheaper Solen metalized film
caps. A large wire air-core woofer inductor will reduce
resistance and stabilize the crossover frequency at high power,
too. It will raise the output of the woofer a fraction of a
dB.
