There are some same dips although it isn't perfect matching

The my conclusions are:
1) The EMU0404 USB + Arta software + ECM8000 mic. is good combination like the Clio system and it give some more possibility to manage the measurements parameters.
2) In both case the low frequency measurements in a normal environment are very difficult and the result is compromised by many factor.
3) Changing the time of MLS impulse for medium and high frequemcy does not change the result and 20msec is good for all the band
4) The SM115N have a good linearity also out of axe in medium frequency and it have a good low frequency band.
5) The ECH8000 calibration it is not necessary for measurements in a normal room.

Helmuth, what you think about ?

1) That combination is probably just as sensitive as an new clio-system and wil have all main features.
2) Yes with restriction you can see in the impulse response that the measurement is disturbed by reflections. It can be reasonable accurate.

Also help mathematics filters like hanning and hamming blackmann increase accuracy.

3) I use 20msec or even 10msec to measure hole response of the speaker. Because the low end is some how unreliable and there for not so important.
4)It looks very good when you use room gain the right way your onken will do even 20Hz at about -8dB I estimate. I would place the port on the back near the floor to use room gain.

Grey line is the port response of the woofer by placing it near the floor the -10dB raises 3dB and with the back wall another 3dB and a corner another 3 dB. So you can lift the output of that port +9dB.:D

5)In the area to tune filter and non linearity of drivers between about 100Hz -8000Hz a uncalibrated EMC8000 is just as reliable as a calibrated one because it is as flat as a line there.:up:

I'm wondering how repeatable the performance of the mic capsule sample to sample is in the ECM8000 as I have one too, and no reliable means to calibrate it. I've always figured the measurements I took with it were probably no better than +/-2dB relative to some arbitrary reference point centered about the mean of the error band. Seems reasonably close.. :D

To be honest I do not trust the calibration data of my own microphone.

I tested it with tweeters I have (dsm25ff,RT1 ribbon,horn-drivers) compared to the spec . And it appeared to me it was more accurate without the cal-data.

I think that if you are worrying about +/- 2dB for real in-room measurements with an omni mic, you should find better things to worry about.

If you are a manufacture measuring in anechoic conditions, that's another thing.

Spent 10yrs at a notorious large speaker manufacturer in New England so I should know this better than most, still it is very hard to get things like X-O design and driver integration right if you have no confidence in the microphone you are using.

Incidentally my system did measure in room to +/-2dB from about 100Hz - 10kHz the last time I made a serious effort to do so and obviously this includes the mic error, but I have no idea how much is the mic and how much is the speaker system, and no data to make any assumptions, although I assume the most significant errors are on the speaker side of the equation. (It takes very careful mic placement and a lot of measurements to get these results.. )

WRT to Helmuth's comments my suspicion is that calibration table reflects the performance of both the mic and the speaker used as the calibration source which must first be measured by a calibrated mic.. :D I use mine with no corrections at all..

:eek:

Is it a measurement at one position, or averaged by several points...

or, they are all within 2dB at several points? :eek:

I should have made that clear, no the measurements weren't averaged - I just laboriously looked at the results from a number of different spots in the room independently - obviously having found a spot where the response was that flat I naturally tried to place my listening position in about the same spot. Of course I have moved things around since, and recently changed to a different midrange CD (JBL 2440 vs the old 2420) so who knows what I am actually getting these days..

The big problem of course is at the bottom end where there is a huge amount of interaction with my room. I've had problems making gated measurements even with arta. Recently upgraded hardware might solve this issue, but I am not yet ready to do new measurements.

Overall I am pleased with the room acoustics and the sound I am getting. The whole synergy thing is unlikely, but there, and works well with my Onkens.

Andrea,

Someone should have mentioned this before.. but an "aligned" response is usually all wrong. :xeye:

In particular, (on the lower freq. end), you have room-gain and baffle step compensation to factor in. (..Higher in freq. you are likely to have floor bounce issues with a 15" driver.. depending on how close it is to the floor and if the baffle has significant angle departure from vertical.)

As far as the lower freq. response is concerned:

Depending on the baffle - most baffles will need between 3-5 db of compensation at 100 Hz. However.. rooms (depending on the shape, construction, losses, etc.), often have about 1-2 db of gain 100 Hz. The "average" net then is typically about 2-3 db of baffle step reduction at 100 Hz. Progressively greater reduction at higher freq.s, less at lower freq.s.

With an aligned response AND baffle step compensation the lower freq.s (below 100 Hz) become increasingly elevated above the average. This (in combination with extended group delay from the port's contribution), usually leads to "bloated" bass. It gets even worse if you factor-in a tube amplifier's gain from the reaction to the impedance swing.

The "funny" thing is IF you factor-in all of the above.. the Monacor SP38 in a *sealed* enclosure slightly LESS than the design you had for the Celestion.. with baffle step compensation SHOULD give you something similar to what you targeted with the Celestion. :hot:

Here is Martin Colloms "average" room-gain guesstimate:

http://www.diyaudio.com/forums/attachment.php?postid=88719&stamp=1038551652

Here is the Edge to work with baffle step loss (& compensation):

Home of the Edge

TIP: ..look to Erse for cheap but decent large value capacitors (..and of course by-pass with something better). ;)

I have to totally agree with ScottG, it is essential to factor in baffle step and room gain for a design such as this. Room gain will add 2-4dB in the 50-100hz octave, and baffle step will losses are likely to cause a loss of 3-4dB from 500hz and below (dependent on width of baffle). I usually compensate for room gain by using extended bass shelf alignment to avoid "bloated" bass and add variable active (passive r-c network before power amplifier) baffle step compensation to balance the losses cause by baffle step losses. The high source impedance of any tube (valve) amplifier increases qts. which also increases the tendency to bloated bass. To compensate for this you have to adjust the qt. value (increase) of the driver in any simulation, this usually means either/or using a larger enclosure or extended bass shelf alignment. If these factors are ignored then the result will be bloated bass, a depressed mid bass and shouty mids. ScottG knows his stuff!
 
I am going to build the Onken enclosure with the Celestion ftr 15 driver, but i cant get hold of 30mm plywood.
I have 22mm plywood and understand that it means i must change the dimensions of the plans to convert from 30mm to 22mm plywood.
I want to get this right so i would very much appreciate any help.
Best regards

I have 22mm plywood and understand that it means i must change the dimensions of the plans to convert from 30mm to 22mm plywood.
I want to get this right so i would very much appreciate any help.
Best regards

You can gleu on a second 8mm plywood then you become 30mm. Butt you can not copy Andreas design and place a other driver and aspect it will work as a onken.

It seems to me you're a new one to speaker design and do not know the relation between Thiele-small data and enclosure size..
 
You are right, i am new to this, i have the same driver as used in this link though:
Hi-End and Hi-Eff loudspeakers system
The Celestion ftr15-3070c drivers are already ordered.
I thought i could change the plywood from 30mm to 22mm and get the same result/internal volume with some math work...
But i guess i might as well just glue on a 8mm sheet on each 22mm sheet. Sometimes the most obvieus solution is right in front of you but you just dont see it :)

It is propably the safest solution in getting it right.
I will be using an active xover for my project, split at 800 Hz. and use a woodhorn on top.

Thank you very much for the response :)

Stop!

Ask Andrea for the right volume and bassreflex port size for the celestiondriver. It is not the same as for the beyma sm115 andrea used.

You will have to design a other size box and port or only a other size port!

The plans i have is for the #1 Onken enclosures, there is two plans made, for the Celestion driver:
Link: Hi-End and Hi-Eff loudspeakers system

And one other for the beyma driver:
Link: Hi-End and Hi-Eff loudspeakers system 2

So i am pretty sure the first link is for the Celestion driver, the parameters and the Onken Calc. match my Celestion driver :)

Thank you for the response
