Hello to everyone!
I am new in this forum. I have been following threads here for some time now, and learned so much.
I have a 2 way Speaker designed with Focal TC90 TD5 tweeter and a PHL 2401ndu Midwoofer that works pretty well. I actually use it for Recording/Mixing duties at my personal Studio.
As the PHL is a midwoofer, It won´t get lower than 65Hz in flat response. So I use an active Subwoofer to complete the spectrum.
My idea is to redesign the system, and take it from a 2way to a 3way system adding a woofer/subwoofer. But honestly I am a little lost with my choices...
So far I have been thinking of buying two Volt RV3143.
I am really open for suggestions as I am a noobie at this...
What other models/brands would you suggest? I am looking for the most flattest & transparent sound as it is aimed to be used in mixing/mastering.
Thanks! 🙂

The tweeter is xover freq with the PHL is at 2500hz. And the PHL goes down to 65Hz aprox.
My idea is to make a xover freq between the PHL and Volt at 300hz. But if there is a better woofer than the Volt than someone can recommend me, I am sure this will change?

Do you really think so? I know I am a noobie about DIY speakers but I don´t follow this statement very well.
I have seen lots of desings mutating until they get to their best performance. Not saying is the best way, but it can perfectly be done.
I believe the coherence between the drivers should be as best as possible. Including xover design and cabintes of course.
If it is possible to custom build a 2 way design, why not a 3way? using the same drivers? and adding a wwofer/subwoofer

I think you guys are mis-understanding Troels, he's saying it's not a good idea IF you only want to use a simple 1st order over.... i.e. it's OK if you use a proper crossover.
(And in practice, a simple 1st order crossover will actually work in many situations)
I would suggest that the OP cross over his woofers at the baffle step frequency, what is the width of your cabinet? (It would also help if you posted a link to the data sheet for your mid driver)

I’m not saying you can’t design a 3-way using the drivers used in a 2-way. Troels explains (and I concur), that if you have a properly designed 2-way it is difficult to turn it into a 3-way AND you lose efficiency in doing it. If you redesign the original crossover it can be done. Properly designed is the key however.
I had a look at the existing drivers and I have some doubts about the existing design: a 8” low Qts high efficiency (94dB) driver mated to a 3/4” tweeter with a 2.5KHz crossover. The manufacturer don’t even provide FR for the midwoofer, but I wouldn’t cross any 8” mid so high and the Focal tweeter so low.
The Volt woofer will provide the bass you need, the PHL won’t provide any, as it has too low Qts and too high Fs.

Yes no problem or not too much with a new xover. Ideally, you should take measurements of the HP and then prepare a simulation with software.
For the simulation VituixCAD2 is free, and for the measure REW si free too!!

Great to hear! The idea is to choose a woofer and run simulations, build a prototype cabinet, new xover.
But, what do you guys think about the Volt RV 3143?
Would you recommend another woofer/subwoofer for this project?
I am looking for a clean, transparent sound that can match with the PHL woofer.

Looks interesting!
Decent freq response... although, maybe a little to powerfull? 600w that might get attenuated later...
nice price too...
Any more suggestions? 🙂
