What would be involved in updating Hersey II’s to Hersey IV’s?

If the new Heresy speaker are ported then I would gravitate toward the versions that are not ported. I feel that heavy mods on the Heresy is kind of like putting lipstick on a pig.

No doubt every speaker could benefit from mods, but Klipsch and mods are on an entirely different level than most or all other speaker brands of which I am aware. 

To answer a few questions or address a few responses to my posts.

Sorry but I guess you have to be a Klipsch fan to comment on any Kilpsch related post.  So funny that some would take criticism so seriously. True, I probably can come up with things to complain about with any design but Klipsch gives me the most ammunition as this relates to qualities that are most important to me.

Of course the lipstick comment was made as a indication that I think modifying a Heresy is somewhat of a waste as I think that this design has numerous flaws. If you are going to go Horn, by virtue of the drivers, you need to go big.

I cant think of another brand of speaker which almost requires modification to bring it to a palatable level. At the very least, even modestly priced modifications can make a big difference on Klipsch. What does this say about the speaker as they leave the factory floor?

What strikes me as strange is that Klipsch would increase the size of the Heresy cabinet after introducing a port. Seems to go against logic. I strongly prefer sealed designs over ported and to a lesser degree transmission lines.

From my perspective, I have never heard a Klipsch speaker that I even disliked without mods. Dont get all bunged guys, I am not insulting your children and this is just an opinion of a person that really doesnt care for horns overall.

Usually a sealed cabinet requires a larger cabinet. Obviously I dont agree and think that the Heresy and to a slightly lesser degree the Fortes dont sound like real music. I will give you the efficiency part, but all other aspects fall short of others designs in my experience. I have been listening to Klipsch for over 30 years and they just arent my cup of tea. The one thing I have found is that feeding Klipsch with as much tube power as is possible helps the speakers. This comment is more about the behavior of lower powered amps than the speakers. I would be interested in what other speakers you have compared with the Heresy in your home.
