Thanks for the in depth review of these. I know you are liking the Focal 6.900 amp. Any others that you feel would be worth upgrading to?

I am extremely particular about amplifier quality

in contrast to speakers. I believe that a high quality amplifier with enormous reserves of clean power trumps speakers and a mediocre BMW hifi head unit in the F22.

If you are starting this hobby, spend the most on the amplifier. My Focal has paid dividends year after year.

Once would think my Hertz and OEM subs would have blown up already, with my amp maxed out, but after 4 years of listening, it amazes me how enormous amount of clean power prevents speaker damage.

This is the amp, but sadly no longer made.

Zed Audio/Leviathan III. If you can find one second hand and it is working, you have won the lottery.

Guess it's worth the investment! Definitely don't consider myself an audiophile, but do want a bit more oomf out of the subs.

Thanks again for the recommendations and sharing your experience.

So - after reading this thread - would it make sense then to treat the front 3 speakers as a fancy 3 way? You have tweets for very high, the mids in the doors for upper mid, and mids below the seat for lower mid, and then have a true sub in the trunk for the extreme stuff?

I have coaxials which combine the tweeter with the woofer in the doors. For really low frequency (more sound that is felt rather than heard), a trunk sub will help.

In my honest opinion, for most listening, the underseat subs are good enough with high quality amplifier power. Just don't spend too much.
