magnepans with a sub???

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.

I have 3.6's powered by a Classe CA300. Once in a while I do get in the mood for a crank up session and while it does get up kind of loud, every now and then I'll hear the diaphragm slap/bottom out and I immediately turn the volume down.

I guess I need more power but what I normally do now is hook up my NHT 3.3s when I want to rock.

I was even thinking of getting cerwin vega PA speakers along with their amps for a crazy loud system for when I'm in the mood to really get nuts.
