Identify Good $500 Speaker by Graph

[Alex2507]

Here's the graph on the left:

I really need to know which speaker generated this graph.
PM me if discretion is required but really ... I must know.
If super secrecy is where it's at, I'll give you my phone number so that you can just tell me.

Can I borrow your hd glasses and sonic ear


EDIT: Im pretty sure I just got OJed

Sure ... if I can borrow 500 bucks.

That looks a bit like a graph of a GR speaker.

Probably a small 6" 2-way pro audio studio monitor with a horn (aka "waveguide") tweeter. Sean would know which exactly

The Behringer B2030P has an even superior response graph, and it's only $150/pair.

Note: The full-bandwidth response graph below did not have mic correction applied; as a result 6-12kHz band has about a 2dB rise that does not exist, making treble appear dead flat, when in reality, it has a slight gradual reduction as frequency rises.

Mic correction is applied to the following graphs. Also, off axis plots cover 0 to 90 degrees. The plots for the OP's initital post graph is not listed; but commonly such graphs cover 0, 15 and 45 degrees or 0, 30 and 60 degrees. It is unclear what is used in the OP's image; maybe Sean will specify.

If we take the easy route and assume it's a Harman product, how about this one?

http://pro-audio.musiciansfriend.com/product/JBL-LSR-2325P-5-BiAmplified-Powered-Studio-Monitor?sku=580377

Selling for $199, MSRP $249 a piece ($498/pair). I don't see any graphs of it on the JBL site.

Could it be the Primus 360? Maybe it's the street price of a pair. Does the bass go deep enough? I can't tell from the small pic.

BTW, that Behringer on-axis doesn't look all that impressive. Maybe for the price. It's hard to tell with the small pic, but it doesn't look as flat as the "$500 wonder."

So I take it he didn't fall for the cute face in your avatar....

The graph is excruciatingly small and difficult to see, but given what appears to be the LF roll off, yes, that's a very good possibility. The FR may be in the manual, but I didn't download it. Here is one from the next series up (4300)

cheers,

I'm sure the fact that one is a chamber reading causes issues, but the Behringer is still very impressive off-axis.

Care to name that mystery loudspeaker Sean...

I would tell you if you look anything like your Avitar

I had to get a neighbour to come on over and take my picture ... just for u Sean

You need to apply a rotation and keyhole deformation to the screenshot from audioholics to get it to match the angle of the screen.

Yeah, I was just about to say that.

At this point I'm not much interested in speakers but Riker seems to have a point.

The 2030P's are nice but they just don't go very low. I really prefer my Primus 360's to them. I'm just talking about their use with rec'r grade x-overs and entry level subs.

Let's open the door on this to see if we can identify all of those speakers in the graphs. I don't expect that Mr. Olive is at liberty to say and he's probably smart enough to see right through me. I could never be trusted to keep it to myself. I would sing like a freakin' bird.

You really have to pay attention to the graph scales and frequency ranges used in each graph. Here is the $500 mystery graph(with enhanced FR line) and the mic-corrected response on axis of the B2030P, scaled/sized to match the mystery speaker graph, and now you can see there is far less visibly percieved difference in the response now.

The 2030P blue line has dips at 1KHz and 3KHz and I wonder how noticeable that would be. I mean that's where we hear just fine. The dip at 10KHz might be out of the range that I would notice it at so much.

The LF ability of the mystery speakers looks nice and the HF roll of at 18KHz listed in Riker's JBL's seems to match. Do we have a winner here? Those look like a really nice computer speaker solution ... ... but not enough for real speakers due to the 50 watt woofer ... but I live in a condo ...

Those would outperform most "real" passive "home audio" speakers of that size. The 50 watts (RMS) is exactly enough for that driver. 115db peaks would probably get you thrown out of your condo (or at least some calls to the police)

Depending on the impedance curves that 50 watts can get sucked out quick in just the right part of the response curve and leave the speaker sounding like it's less than it could be but your qualifier of 'for that size' is completely agreed upon. That 115db peak is at what, a meter away? I didn't read all the info but I seriously doubt that I would trade externally amp'ed Primus 360's for those.

You're 110% right about SPL's and condos. I guess about every other month I mention that I keep it toned down in the evening and when I do let it rip it's brief and timed so that it might blend in with the sounds of daytime traffic and what not. Even in the daytime I wouldn't dream of playing ear bleed levels for hours. If somebody did that to me ... it wouldn't be appreciated ... so ...

Allrighty then

The roll off on the B2030P has always been known. Even Behringer specifies it should be used with subwoofer(s). Power handling rises considerably when you do this (and high pass the monitor speaker as it was intended). It is a full range solution in this capacity.

Re: the dips; the point was not to show the B2030P was exactly as smooth, only to show that the differences were only minor, when you scale and compare graphs on equal grounds. The dips, btw, are narrow, and would be audible by a very small degree. If one has access to a parametric EQ, then you can experiment with it and observe how audible narrow dips will be.

The power response is of course, better on the B2030P, with near equal response plots out to +/- 60 degrees, even past 15kHz. The B2030P starts to reduce power (in a controlled manner) as you approach as pass +/- 75 degrees.
