so that jbl control 1 pro pair i bought… yeah, those are just not good speakers. you can hear the build quality. thin sewer pipe ABS is not the material of choice here. they have that characteristic “cheap PC speaker” sound.

which is a shame, really. the drivers seem to be decent enough and will take a hot supper (the 150 W RMS rating may not be just for show), but the cabinets are trash. the reflex ports are super noisy, too.

the result with DRC is pretty okay all things considered, but i would only use these for listening at a very close distance and moderate volume levels. in other words, they are good as PC speakers if you also happen to have a measurement microphone or an afternoon to try and EQ those things, but at that point just buy active studio monitors tbh.

so yeah, these go in the bedroom for mainly ambient music. gonna have to find something more appropriate for the living room. ordered a pair of the box pro achat 206, will see how well those work.

Klipsch La Scala for the living room. They run well off of 30w rms. That is if you have the budget and the physical room to fit them. I have neither but I dream..

@paulgatling right now i’ve got two 15" cabinets on the wall (no good place to put them on the ground) and it’s just not a good look.

the point is to go “smaller” without compromising on the overkill factor. amp power is not a concern, i’ve got plenty of that.

the achat 206’s are pretty small. they can just be mounted right under the ceiling and are easy to hide. they also don’t need to handle anything under 100 Hz because I’ve got subwoofers hidden in a corner for that.

as a side note, i kinda gave up on consumer audio equipment in general. the only thing it does better is looks, and PA equipment necessarily sounding worse is a myth as long as the speakers are well-constructed. it’s much more important to take the entire listening space into consideration, which is where room treatment and digital correction come in.

Quite a refreshing audiophile perspective! I get kinda upset at folks that claim the sound is the most important thing yet freak out over a small chip in a cabinet or a slight wrinkle in a cone when it is still doing a fine job of making the sounds we love. You've dropped a few model numbers I've never heard of but I will be looking in to.. good luck on your pursuit of a killer system!

@paulgatling so i looked into the la scala speakers you mentioned and all i can say is

wow what a phenomenal waste of money

@paulgatling i mean i get it, you might WANT coloring from your speakers, but when a plot looks like it’s just badly matched components thrown in a cabinet with obvious resonance problems… i find it hard to justify such a purchase

Well.. that hardly is a flat or even a gentle slope of frequency response.

They are efficient though. I wonder if that comes from the porting in the enclosure. Ah well, they were always so far out of my price range that I never looked at their specs closely and I'm guessing that the reviews and testimonials are biased by trying to justify the cost. The numbers don't lie though

@paulgatling they’re actually lying about the efficiency, in reality it’s closer to 100 dBSPL/1W/1m instead of the claimed 105.

@paulgatling with hifi gear, there certainly is no shortage of people writing reviews despite lacking critical listening skills. it’s easy to recognize them because they lack the vocabulary to accurately describe a speaker’s performance. you want to read something like “exaggerated mid-highs” instead of “tinny” or “crisp” or “bright” or however they call it.

in the upper price range they also love claiming “the pros use these in studios” and other nonsense that doesn’t tell you anything about the quality of the speaker.

Totally true and having dug below the surface you've managed to really show these to me for what the are. You are spot on about review vernacular and I almost never see someone speaking about mid-range and levels. Often times they refer to their favorite music (which is almost always appalling to me) which is not a good measure because recording quality and input sources always influence this, not to mention whatever questionable soft rock or easy listening that has its own mix down.

Having said all of that, that would you recommend for efficiency and even response for a midsized cabinet? I too have a sub that can deal with the low end. Clarity at low volume is a must. I am partial to horns but clearly I will listen to reason and good specs. Price is definitely an object

@paulgatling that’s not nearly enough info to make any recommendation. you are trying to select components for a system with many parameters.

and don’t forget i’m still figuring things out myself, on a very restricted budget, so my actual experience is extremely limited.

those large cabinets i’ve got right now are the box pa15eco mk2, and suffice it to say they fail the knuckle test. awful, but okay for the price. the frequency response plot includes the subwoofers (x-over at 75 Hz) and is measured from the couch facing the screen in the living room, hence the pronounced comb especially below 250 Hz — might be worth looking into bass traps (and a way to disguise them). it is hard to overstate how much digital correction helps here.

Good point, and I'm assuming the blue graph is with DSP? Looks a little more smooth.

I have been thinking of making my own but honestly the cabinet creation is the most intimidating aspect to me.

@paulgatling yes, blue is with a correction filter generated using

that’s also not just a little more smooth. the difference in sound quality is anything but subtle irl.

but of course correcting at the signal source has its limitations. the smaller the room is acoustically (i.e. the more reverberation, resonance and so on you get), the harder it is to correct. stronger correction will shrink the listening sweet spot and have its own artifacts. that’s why room treatment is important. but of course a living room is not a studio, and you don’t exactly want walls covered in acoustic foam there…

@paulgatling here’s a fun one as an extreme example: a shower stall with a ceiling speaker! there’s some insane low-frequency resonance and obviously a lot of combing due to the reverberation, but drc does some real magic there.

of course if you open the stall door the bass goes through the roof again lol

@paulgatling this is what the impulse response of that stall sounds like (that’s generated from a sine sweep)

@paulgatling now here’s the bedroom for comparison. much better!

Again with the bedding, probably carpet but at least a rug, curtains on the windows, all of these things absorb that sound and keeps it from bouncing around..

Hahaha that sure sounds like a smack in a bathroom alright! All the hard surfaces really cause issues with sound.

Now how are you tuning this, with a microphone only? Like you said, with heavy digital modification, the sound experience would vary widely across your listening area, or at least has potential to. Do you ever mess with an SPL meter? This is all very fascinating and your ability to chart audio performance is on another level cool!

@paulgatling that’s done using a special measurement microphone. i’m using a beyerdynamic mm 1.
