Default Kofi Annan in: "Subs -n- Supravox!"

Hey!

So, I just finished the Steve Bench phono pre with Salas' shunt regulator for the power supply and it's time to talk subwoofers.

My current system includes some 300b monoblocks into either a pair of Fostex 206e backhorns (in the 208E-Sigma enclosure) or a set of Supravox 215 signature bicones run on open baffle, which is what we're here to discuss.

I'm thinking I would run some Eminences (Alpha?) with the open baffle Supravoxes, but any guidance on this would help. They're in a pretty big room and I need a good degree of bass help to round out the sound.

Any advice would be appreciated.

Kofi

I am open to all ideas. I have seen a pair of Alphas per channel and one Supravox on one OB before and I thought that had potential, but I am willing to consider anything.

Mmmmm... I thought I would keep it simple and have the subs run from a plate amp, but I would also consider active / ss amping them. I would need guidance on all of this, of course...

A pair of Alpha 15s are common here, but only on OB - you couldn't make a boxed sub with them.

So, if I wanted to OB these with the Supravoxes, what would be your recommendation. I am new to subs, so please be gentle.

As far as active crossover goes I've got a reckhorn f-1. ~$50 from CSS. It's much nicer than what was in my plate amp. I like it a bunch.

Emminence or big cheap Goldwoods in an H-frame is what I see mentioned for open subs, not that I've experimented with that setup...
