Hello,

I am having a shop relocate my Focal ES 100 K to the rears in my GR Supra and retrofitting either the ES 165 K or ES 165 K2, but I wanted your guys input on what would be ideal for my setup and reasoning for it. Car will be getting custom front door panels made to accommodate for the larger woofer and retain an active setup.

Available Power: (mObridge K2 MOST25 8.1.1. Amp)
Channels 1&2: 100w [email protected]/140w [email protected]
Channels 3&4: 200w [email protected]/280w [email protected]

Between the two I've noticed the K2 has a 2-ohm woofer and a phase plug. Any other important features for the $150 price bump?

Should I be concerned with the bump in power going 2-ohm?

Should I even consider the KX2 model @2-ohm. Would it be worth the $300 extra over the K2, considering I'm not going to use the crossover?

 

[Mag1c Carp3t]

Yes no need for the bi-amp crossover, considering the power we have available. I also would prefer not to stress the amp as it does not have a fan or heatsink to cool it down.

Edit: Spoke with mObridge, the amp is pretty stout at heat dissipation, so should handle the load.

Should I run the 4" Focal set, that is going to the rear, active? I would be sacrificing my center channel.

We ended up deciding on these woofers to go in the doors.

What do you guys think, I plan to cross them at 80 Hz - 3,000 Hz LR 24/dB.

The vender was able to split the 3-way kit up so we can re-use my es 100 k tweeters. I'll stick the es 100 k 4" woofer in the rear and run them as rear fill.

Those are badass even better than the first two! Great choice!

How low can I play these woofers on 200w rms @4-ohms. Will Lo-P around 2360Hz.

Got the drivers installed, check it out.

Maybe 60hz /24db but I would do 80hz no need to go lower with proper EQ… which will increase midbass

Yes running them at 80hz/24db and subs at 60hz/24db.
