Reading through this interesting thread it looks like the factory crossover is the same for single woofer/ double woofers? I am not an acoustician in any way, but a few other companies have done 3 way loudspeakers with double woofers off of a single two way x-over (Meyer & Community). It's (somehow) the loading in the cabinet that makes these designs into what they call a quasi-3 way. So it's the cabinet not the crossover that makes it a three way.
Note that the graphic in #21 shows both drivers to be the same in the dual configuration.
L-Pads in my experience have a habit of catching on fire.
Yeah but the woofer has a very steep crossover 36 db with high Q do is moot if it's single or dual woofer below 650 hertz.
The horn in the other hand is relatively gentle crossover of 12 db per octave do is still heard as a point source on the mid and highs
I'm way late to the party. Just wanted to note that the "basic input/output connections diagram" that came with my TN-4 does not list a single LF driver as an option. The chart gives info on the "HF" section and the "LF (dual parallel)" section. Nothing about a single LF driver option.
Whether that means there's more than one iteration of the TN-4, I don't know.
Does anyone know which speaker modell has used the TN-4 crossover from factory?
As far as I know, all TAD-monitors crossover at 650hz, but the TN-4 has itīs crossover at 800hz...
Very simple question :)
This was used in PA TAD loudspeakers TCM-1822 and TCM-1622

Unlike one version of its manual, TN-4 is only for the use of two LF units in parallel. The HF section is for use with TH-4371 Horn, and has no EQ cell.
Do not use TN-4 for loudspeakers like Exclusive 2401 or 2402 or with ARAI290 horn it isn't made for this.
Great info, thanks!
I was interested in the lowpass section for the woofers... ;)
Do you know the value of the inductors?
I tried to do some measurements and as the TN-4 wasn't mine I was not able to remove components from the circuit. It is on a piece of paper that I've to find, but I remember it was more or less a 650/800 ratio from TN-1 LF.
This network has a role with its group delay in time alignment with the TD-4002z on TH-4371. The chosen frequency corresponds to what was needed.
Is it for a dual woofer system ?
I understand... ;)
Thanks a lot for your help!
