What is best sub to match with Magnepan?

I just bought a pair of Gallo TR-3s from an Agoner. I'll let you know how they are with my 1.7s when they arrive this weekend. They're supposed to be spectacular!

I would look at a VMPS sub, back when I was looking into Maggies many told me to try this sub, as it has some clay ribbon that you can remove or add as needed to speed the woofer. Another way of thinking about it, is it comes from a company that uses a lot of ribbon speakers, in their own speakers. I have had mine for many years and love it still.

LS, you seem to have a case of the planar bass blues. This is caused by your having discriminating tastes, being able to appreciate what planars can do for you from mid-bass to treble. The fact that you find your sub to be too slow is just further evidence of that.

Sorry, but I have never heard a sub which was fast enough for Magnepans. I have rarely even heard a cone speaker which can differentiate notes in the bottom octave, for that matter - mostly they just thump and thud in a sluggish monotone - unless you spend real money.

The only solution which satisfies me, is to buy a planar speaker with as much low frequency extension as the budget allows. Even ancient MGIII's extend the bass down to nearly 30 Hz, which is really plenty low. To test this, put a 12 dB filter with a 30 Hz crossover in front of your sub, and dial the sub down to 30 Hz as well. Then play a record with lots of bass. I think you will be surprised at how little signal comes through. Unless you goose the bass with tons of gain, of course.

I think you have no choice but to save up for pricier planars. Put it down to the cost of having good ears. Good luck!

I recently took one of my Velodyne HT subs to a friends home for audition, also to show him what he's missing with his Maggie 12's. I thought the F1200 sub integrated very nice. They are very cheap on the used market,or if you want to spend a little more and get a newer version look into the Velodyne HGS series.

Unfortunately, so many folks try to use the LFE connection and sub x-over and place the sub behind the plane of the main speakers. First, I would only use speaker connections so everyone is getting the same feed. Next, open the x-over all the way and adjust the phase and gain to match the mains. And last, place the sub on a plane in front of the mains, maybe a foot or so. If you think Vandys or most any phase-correct speaker, this is the design.
