A good subwoofer solution is a Vandersteen 2Wq which uses a crossover between your pre-amp and power amp. This rolls off the bass starting at 80Hz, and the sub has a complementary response curve. With three 8" drivers in a slot loaded configuration, the 2Wq is known to be a "fast" sub and a nice complement to planars. I used one with my 1.6s and loved the combination. All the vitrues of the Maggie with extended and tuneful bass.
Magnepan DWM problem
Just got off the phone with Wendell Diller at Magnepan. I was hearing a rattle/distortion/resonance from my DWM Bass panel in my nearly new MMG Super system. With particularly strong bass notes (Cut Chemist-The Audience's Listening CD-track 2 & 3)at a robust (but not as loud as I might one day choose) volume.The problem only occurs with this type of bass note at this very healthy volume. I was concerned that my panel was defective or that my 110 watt Odyssey Khartago monoblocks were clipping. What Wendell told me was a bit surprising-he stated that this is pretty much a problem with all Maggies!! Apparently the film was slapping against the magnet(if I recall correctly)-I was more than a little shocked. I could not recall in the research I did before purchase or the good deal of Maggie related research that I did since the purchase(or the 2 local Maggie owners I know) did I ever hear this issue mentioned. It is certainly possible that this shortcoming has been mentioned in the literature and perhaps every speaker may have a similar problem but I am still a bit unsure. So please weigh in with your opinions and experience. Can a true Audiophile quality speaker have such an issue? Was Wendell just trying to get me off the phone? Should I be worried about an issue that will not reoccur in 99% of my listening? Many thanks. LS
