EQ and DSP added to rated Frequency Response

I learned a long time ago you never boost bands of frequencies trying to correct for short comings of speaker systems. Other wise distortion increases and limits of the drivers can be reached much sooner. The idea is to remove the peaks and over all over emphasis of the speaker when necessary. I always place my speakers and choose my prefeered listening location for the smoothest response before using room equalization to remove peaky abnormalities.

Bose 901 series speakers have to be some of the worst to deal with in my Experience.
 
Perhaps my thread should have been "Should EQ and DSP be allowed to be added to the Rated Frequency Response"?

As has been pointed out EQ circuits are common in speakers, these circuits being part of the passive crossovers. Most famous among hornies is the compensation circuit of the Altec Model 19 that flattened the midrange hump and extended the high frequency response. Subsequently JBL made similar high performance 2-way hybrid horn speakers with their 4400 series of monitors.

Seems to me whether the EQ is by means of passive circuits or DSP is immaterial when the EQ is part of the system design.
 
To me this sort of thing is a red herring.

Does it really matter if the lower bass one wants comes from a speaker or speaker with sub? To me it does not, and I opine any argument otherwise largely amounts to posturing.
let me know when a pair of 15s in a short horn like a la scala or FH-1 can do this across multiple seats, i'll buy them!

as much as we talk about distortion in here and drivers working their best in their pass bands to not create some that's audible, i absolutely do not agree that you don't need a subwoofer if you're using klipsch heritage speakers or their clones/designs as your main speakers. i won't argue that it does not matter to you, that's subjective. If your point is 80hz sounds the same coming from a subwoofer that covers 20-150hz or a woofer covering 60-1000hz then i guess i cant argue with that either.
If your argument is "i don't need a sub because my bassbin gets to 30hz" then absolutely disagree because mine are capable but not nearly as much as the subs. If you push the woofers in the bins to volumes the subs are capable of at those lower frequencies then they will absolutely not sound the same.

The comment referenced from the one you quoted was about a full range 8" driver. the whole reason were in here is because we like horns doing things in the places where they are efficient to lower distortion. as much as i'd like 15" woofers in big bass bins to get to 13hz, if some $400 full range 8s were all i needed then someone should have let me know about their capabilities!

which sub is this?
4x um18s in bass reflex boxes using MSO and a bunch of all pass filters to make them play nicely in a very atypical room. I'm sure most think it's an overwhelming amount of bass but it's just as flat as i want anywhere on the couch. I'll even argue that a single sub AT BEST can have one good seat and that's a stretch in a good room. I'm also perfectly fine with people not wanting one, not having the space for one, or a multitude of other reasons. There are always compromises we have to make in the audio world and thats ok. I would love some horn subs but the designs i like don't fit in my space......yet

Even though this is the Klipsch forum the OP used Bose 901's as an example in his first post and I think many are answering from the standpoint of including all speakers not just specifically Klipsch.

I think @whoaru99 's point in reply to the specific quote he used from the OP - 22frank is valid.

Edit: he posted as I was typing, I understood his earlier post as he intended.
 
Ahhh... that's what I was afraid of. I think you misunderstood the intent/gist of what I said.
I must be misunderstanding entirely! please elaborate on the logical fallacy i'm missing, I haven't taken any psych in 20 years.

I'm talking about the specific speaker in question from the quote. I don't think this driver or bose 901s are going to handle 20hz at any reasonable SPL, and definitely not in my medium sized room.
 
In a system capable of say 30Hz, the bass can either come from the main speaker or from a subwoofer(s), both are capable of 30Hz.

What is hard to understand?

It's not hard to understand in concept. it's hard to FIND a driver that works in a most scenarios in reality. I'm not delusional and thinking small drivers can't reproduce low frequencies. I own headphones! I'm just being reasonable about their capability to only work when on my head.
Not impossible either, we're really just arguing over semantics on what is bass or subbass or a woofer/subwoofer. My issue is that getting a woofer to cover that entire range to pass to a mid horn at 500hz and still have the spl to match without running into FM/IM or compression is going to be rare and expensive. if you're fine at low volumes in a small room then sure. I understanding we're not just talking about klipsch speakers here either.
