Just curious - how were the gains adjusted?

I know Scott hasn't updated the Fi site, they are listed on his Home Theater Shack forum though if you're still curious. They come in more car-audio friendly impedances and I believe they've got a higher Fs which would help a bit in a trunk due to the massive cabin gain. Not trying to talk you out of things, just trying to open up some other opportunities! Also check out the Cult of the Infinitely Baffled, they provide some general direction on volumes needed for certain T/S parameters. Just beware that it's a home-audio only site, you'll get ignored or flamed for asking car questions there. I'd venture to say that "ideally" 2 15s would be too much/max allowable for a trunk, but "ideally" is often different than the real world. I wouldn't expect you to be able to squeeze more than that in without compromising your performance based on it being trunk-baffled, I've only thought about going this route tentatively though so no real-life experience.

Actually, you should have more low-end extension. The only areas you need to block off are any that would connect the sound waves from the front and rear of the driver. Check out Kevin's application papers on DIYcable, I'm pretty sure he has sealed/ported/IB notes for each driver. It should give you a decent idea on how they'll perform. Any reason you chose his drivers? They're great, don't get me wrong, but I'd also try modeling up the Fi IB3 guys too - they may work better given your application.

Sweeeeet, I squeezed my order in at the last second. One E8 coming my way!

Some good PR info: http://www.aespeakers.com/PRFAQ.php In short, PRs should have 2x the Vd of the driven speaker.

Can you swap a RCA as well to make sure that the amp is getting a signal in to that channel?

Jacob - any way you could send a pic or two my way of the 100.4? I'm (most likely) interested. Would like to find a matching brother for my 1500D.... Email is [email protected]. Thanks!

Are you doing all adjustments by ear, or are you measuring as well? I'm in the (continuous) stage of tuning my active setup as well, and just curious. Thanks! Amish
