magnepans with a sub???


Has anybody tried using maggies with a good sub via a crossover? I used to own some maggies. Loved the sound, but I couldn't drive them to any realistic SPL. I added a sub, and got the bass, but still couldn't get them to a satisfying SPL. I thought if I could could cross them with a good quality sub via a good quality crossover, I may be able to drive them to more realistic levels. Anybody got any thoughts or suggestions?
In advance, thanks!!!

Hi Louisl, I have a VT100 MkIII with magnepan 3.7s. There is simply not enough power. While the VT100 sounds very good with the 3.7s when you want crank it up there is just not enough power. I have since update amplifiers to a Krell 302. This combination sings. With Magnepans you need 300 to 600 watts minimum....
Try the Gilmore Raptor monoblocks they will give you great punch with your 3.7. Good luck and keep us posted.
Louis1,

Read Etbaby's email...that for me is the 5th time i have heard or read about Krells and Maggies. def worth exploring for you. if you want to add tube pre, that should be fine...season to taste.
I use a custom multidriver 3 channel subwoofer system with my MG 1.6. Unlike stock subwoofers mine can easily go up to 400 Hz or so.

After years of subwoofer experience I have concluded that the ideal crossover frequency depends on the type of music. My crossover enables easy selection of any frequency and I use from 40 to 350 Hz, and my subwoofers accomodate this.

If you want realistic high SPL (Rock concert, Brass Band, Pipe Organ. etc.) you won't get it from MG1.6 crossed over at 50 Hz or so. At moderate SPL you will get lower bass, and you might prevent the diaphram from bottoming out. which is a good thing.
With magnepans, more power is a must. Try the 14bsst or the 7bst. The 4bsst is barely enough power. With an external xover, i like the xm26, use a 4bsst on the mid_treble and the 14bsst on the bass. Now, they will stand up and bark.
