Well,

I'm about to order my second Ficar Q18 driver and build a matching sub....

Pic 1: Current sub...(smaller SVS in pic has been sold)

Pic 2: My "proforma" with a little help from a friend with photoshop skills...

Both will be driven by my EP2500.

More to come !!!!!!!!!!!!!!

Matt

Sweet! What's the specs on the 1st build? Volume? Port length? Tuning?

Nice. Is each one wired for 4 ohms?

That my friend is a large sub,.. I guess I ought to say subs! A true representation of the classic LLT I would presume. Looking forward to more.

Per Scott at Ficar:

Quote: With a single Q18 you would be best served with a single 8 Ohm coil (I will have to check if I have any of those left). That way you can run the amp in bridged mode, but still not get full power (which is way too much for a single Q18). And if you should choose to add a second sub at a later date, you would simply run both subs in parallel for a single 4 Ohm load for the amp (making max power for the pair).
