The official T/S are pretty accurate, but outside of modeling LF response to design a box, T/S are pretty limited in use, and certainly not sufficient to design a crossover for example.

Hey, you specifically removed the part about transconductance in your quote :D
Too bad, this is one of the big positives of using a midwoofer.
Regarding crossover design and phase tracking, do...

Now you have said too much Ian, I am genuinely interested :)
Was it a private discussion? No trace to be read/heard anywhere?
Did Greg specifically mentioned replacing the 6dB/oct passive filter with a 12dB/oct active one, one octave above the original one?
I would love to read about this if you have a link.
Polars would be horrid, angled baffle or not
It looks like it is getting slower by the day :(
Is there a problem with the database?
From France, asking for new posts in a thread took a whopping 40 seconds: 10 seconds for the redirection to...
The TAD and JBL are very different animals despite the visual similarities.
In the TAD 2401 both 15" play together up to 650Hz, whereas in the JBL DD66000 only one woofer goes up to the 700Hz...
Hi Ivica,
No info, sorry. I assume it is not TCR but I might as well be wrong given the lack of public info on the subject.
Did you notice an improvement with the passive biamp configuration?
I have never tried this with mine but I have read that the results were positive with the LSR(63)32.
If this is the case then you...
Other things being equal, a higher cone mass simply means a lower mass breakpoint frequency.
I doubt this is the only factor to consider when going from a 2216 to a 2262.
The 15" variant of the...
keep in mind the 2216 is tough to beat though...
I guess that is a joke? :D
Adding a tweeter around 10kHz is easy, and you don't really care about phase coherency there as it is a lost cause...
Anti K, using a lowmid can be rewarding, but it is pretty difficult to setup correctly, especially the crossover with the woofer(s).
3-ways are specially tricky to get right when it comes to phase...
These polars are normalized for 0dB at 0°, so frequency response is not part of the equation here.
Directivity cannot be changed with DSP (well, outside of the crossover region at least) but the...
I have never heard or measured a "modernized" (ie with a properly implemented DSP crossover) set of 4430, but from the technical info I can gather (as well as some subjective assumptions) I guess the...
Hi Steve,
Using a different woofer will indeed call for a different correction.
If you don't want to have to measure and tune everything yourself then I would advice you to stay in known...
The impedance is rising from 7kHz up, so the series resistor will produce less and less attenuation at higher frequencies.
Hi Rob,
There is a typo: the table shows 87dB/1m at 15kHz for 2.83V, whereas all the graphs show that same 87dB value at 15kHz for 1V.
If the voltage value found in the curves is the right one...
There is a typo indeed: it should read 1V instead if 2.83V, as confirmed in the curve page 8 of the EDS: http://www.audioheritage.org/vbulletin/attachment.php?attachmentid=57200&stc=1&d=1350657541

Not quite.
Hi Andy,
If you want more SPL another solution is to use two 2216nd per speaker, in a 2.5-way arrangement similar to the 4435 or DD66000:

Looks exactly like what a spammer would do :D
Just kidding, welcome aboard!
Wait, they mention audioheritage at 10:09! :p
There are some good candidates for both balanced and unbalanced operation now!
For unbalanced operation the current champ is the topping L30:...
I wonder if that horn will be available as a part...
