Do you think you need a subwoofer?

Dear Gregadd: From the planar speakers the Maggies are one that I like it, I had the opportunity to heard he 3.6 in my system ( years ago ) due that the dealer here was a close friend of mine and in a friend's system the 20.1, very good ones.

Yes, certainly I have " anomalies " in the frequency response spectrum on my speakers/room, however I can tell you that our ears ( yours, mine and everyone. ) along our know-how/experience are very good, sensitive and discriminate tools on sound reproduction perception.

Almost all different sub's approaches are valid , this depend of what targets do you want to achieve and what quality level do you prefer.

Regards and enjoy the music.

The aerial sw-12 takes a correct approach. While not cheap (approximately $10k)offers a variety of slopes up to 24 db/octave. It is flat to at least 2Hz and allows a maximum cut in of 100Hz. Thus it will mate well with mini-monitors.It also offers a variety of beautiful finishes for those who are turned off by black cubes. If you like black, you can get that too.

Dear Gregadd: Yes the Aerial is very good option. Its price was a little to much for me but its quality performance is really good.

MK the designer/owner of Aerial was/is the one that made the design of my ADS main speakers.

Raul---What is your view of the method used in the Legacy Focus: Including separate subwoofer drivers in the same box as the tweeter, midrange and regular woofers, and bi-amping with a crossover.

In this way, (i) the stress of reproducing low bass sound is removed from the woofers, and (ii) separate amplification is provided for the subwoofers.

In this way, separation is achieved without the cost of an additional box.

Is there any downside to this approach?

Dear Jim: THis Legay is a very nice approach/design that address the IMD subject between other things.

Downside?, well nothing is perfect: if I was Legacy I will make those bass drivers self powered with a dedicate amplifier that match exactly the drivers needs and take care in deep about isolation between those bass drivers and the whole speaker.

I never have the opportunity to hear the speaker but seems very good and has very good reviews.

Regards and enjoy the music.
