Additionally, here is a simplified version using only 4 EQ points and a filter, tracking within around +0.4dB/-0.2dB from 400Hz to 1kHz, and +/-0.2dB above that:

Hi Tom,
I did a first test in 2016, but never published (nor implemented!) the results.
I did revisit this last February, and ended up with a set of 8 additional EQ points that have to be added...
Yes I guess I could try sanding parts of it, thanks for the advice!
I cannot remember how many coats I did and I am afraid the MDF might be saturated way deep, but it is worth a try!
I heard...
I hope Jakob will not mind if I revive and hijack this thread with my own question :)
I have a set of MDF enclosures that I coated with a water-based filler with the project of painting them.
I...

Oups I meant to write "A -8dB higshef is the exact equivalent of a +8dB lowshelf" in my response.
Gotta avoid typos with those things... :banghead:
Yes good point, the "corner frequency"...
A -8dB higshef is the exact equivalent of a -8dB lowshelf at the same frequency and Q, with a 8dB gain difference.
Swapping drivers will require a modification of the crossover, or going active.
If you are prepared for such an endeavor (measurements + simulations, etc.) then going for a 4" driver might be the...
The BSS BLU-160 and BLU-80x series do have enough FIR taps for phase linearization, and you could probably build the whole correction in FIR if you settle for a 48kHz sample rate.
I would be happy...
That is really interesting!!
Is it a straight 0.75"/1" adapter?
As you have a 2-part 2344 I imagine you might even try to do a one piece adapter avoid the horizontal narrowing in the throat?...

Clearly bad design choices at play...
Is posted a rant...
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...
