Hi:

I have a NAD S100 pre-amp, a Rotel 965BX and this venerable HK 870 100
wpc power-amp connected to Mageneplanars. Opinions sought about
matching a sub are sought.

I am leaning toward two *small* subs per channel.

Thanks

Conventional wisdom is that a corner is the way to go. Crossover point is
considered 80 Hz or lower in order to keep the sub from being localized.
Experiment if you desire, but odds are you will wind up with the sub in the
corner. The bigger the room the bigger the sub should be.

To really get the kind of bass that packs a punch you might need more than
one driver, but you will still want to keep it in a corner

The best bang for the buck IMO is Adire Audio's subs, either DIY or finished
products from them will give truly deep accurate bass into the 20 Hz range
and even below. Another good choice is Hsu subwoofers, I personally have a
DIY sub with a 12" driver from Adire and I think it is one of the best
purchases I've made. Check out their product line at www.adireaudio.com

I agree with Mike on this one.
Subs are the DIY thing par excellence, just make sure they're built
very solid.

I tried matching 2 REL quakes with my Maggies, but couldn't get a good
match between them in my room, despite the adjustable crossover in
them. The solution I have now is another pair of Maggies driven by a
separate amplifier.

DIY-ing subs has the advantage of tweaking them according to your
needs.
You could start with passive versions, and add line-level filters and
amplifiers afterwards. This way, you can adjust them for optimum
response in your listening room.

Hi:

Thanks for the responses. It's the sheer velocity of electrostats that
makes me want to go for small sub drivers so that they can keep up.
Hence two drivers to make them move more air. Thanks for the advice
gentlemen.

Simply no truth to there being such a thing as faster subwoofers.

Agreed. Almost all subwoofers are driven through electrical low-pass filters
with roll-offs in the 60 to 140 Hz range. They set the speed, not the woofer
driver itself.

A "Fast subwoofer" would be a midrange driver.

What about lower cone mass?
Say 2 x 10" instead of one 15"-er?

Righto! There are only slower ones.
