I want to take a shot at posting some of my experiences with another speaker. These are all my opinions and personal experiences your mileage may vary.
Klipsch Heresy speakers…I am the happy owner of a pair of 1984 Heresy model speakers. This speaker is the “baby” in the Klipsch Heritage line of loudspeakers and has an interesting and colorful past. I am the second owner of his beautiful pair which came with the original packaging materials and paperwork. (I LOVE OCD, meticulous audiophile owners… 
)
My speakers have had no upgrades and are 100% original and continue to function as designed w/ no degradation in sound quality that i can hear or even suspect. This model has been difficult to work with. I have used them in various locations in the house along with a good variety of source gear over the past 3 years. This model is particularly heavily maligned and cursed by the audiophile community, usually by folks who do not bother to take the time to understand how this speaker operates in different environments, or worse yet who flatly ignore its limitations and compare it strictly to other speakers in its price bracket with no regard to its own actual abilities. These are not cheap speakers and the newest models retail for a fair chunk of money.
I have opened mine up in order to inspect them and properly oil the wood to refresh it of its natural moisture, completely from the inside out. They are a very simple design with almost nothing beyond the birch plywood rectangular box you see in front of you. Despite their simple design and the criticisms many an audiophile has made of them i went out of my way to locate a pair and have spent good money and time working to coax the sound i have heard these speakers reproduce in a well thought out showroom environment many years ago.
I’m currently running my speakers in a small 12x14x8 room that is acoustically quiet, it has good sound absorption but Is lacking in length and is typically boxy without enough room for me to get some better distance from the speakers so it is basically a near-field experience / environment. Not horrible but far from ideal for use as a music room.
I was surprised by how close i could be to the Heresy’s and actually get what I perceive as excellent music out of them, I have them pulled forward about 1/3 the distance into the room, which puts my head at only a 7ft or so triangle. They are tight, with a deep and wide soundstage which encompasses the whole 12 ft width of the room along with sharp pinpoint imaging, I use a small 8” REL subwoofer to reinforce and bring the bottom end into more respectable range because these have a spec’d limitation of around 55hz on the bottom end so using a subwoofer is essential if you want them to go lower. The newest models have a slightly better low end but not by much. They can be fatiguing and harsh with the wrong combo of DAC, amp and room. The upper end in these does not hold back. The midrange is forward it has vivid presence in the music. The mid bass is very tight and a true joy to experience in many vintage rock classics, along with blues, jazz, indie and the like. I have enjoyed modern pop, rap, R&B etc on these, but they are not my preference on these genres, I don’t usually want this much detail in such genres. This is an extremely lively and vivid speaker that took patience to find rewarding combinations for my personal sound preferences. I have a preference for the speaker on tube amplifiers w/ laid back or analog sounding DAC’s. The top end can be tamed to my preferences and I find it very enjoyable when it’s not at its maximum output or performance ability. The midrange sound is a personal preference w/ my music choices and as such is part of a regular rotation into my system every few months.
Would i spend upwards of $3k for the newest model, nope, because i am not a fan of the new port, but yes i would spend up to $2k for the older models because the sound signature is one I want available to me when the mood strikes. These speakers have detail, rock solid imaging, excellent depth and width along with the ability to disappear in the room if you are fortunate enough to get the set-up correct. They are not for the timid and would not be my choice for an all encompassing system as the only pair available to me for use. I would not recommend this speaker for audiophile neophytes and those whose equipment choices on hand are limited. I have used this speaker as part of an all Klipsch home theater set-up in the past and even though I found them excelling in that role because I was able to add DSP and mate their sensitivity to the rest of the system output they are expensive for their roles and I only tried them as such because I could, not because I would.
I have been using them in 2.1 near field music only for several weeks now and continue to marvel at their abilities and for the moment have no desire to swap them out. They are a solid recommendation for more seasoned users who want a unique speaker which scales immensely with equipment, positioning and room treatment and has many upgrade and modifications available to be done should they choose so as part of a DIY project. Happy listening always.
