Novice stereo subs project with stereo amp.

Forget about that... I just found the shadow box on your site. Would there be any way to make it about 24inches high? My idea is to use the subs as stands for my monitors. If not possible, no big deal. It just would be nice to be able to do that...

To Dave or anyone,
With the Reckhorn F-1 stereo unit there's no phase shift adjustment. Most sub amps has that. I'm wondering if that missing adjustment will likely give me some headacks to properly integrate the subs with my monitors???

Jack definitely has some major deals. I bought 10 of the Foster plate amps off him.

I got my woofers from Jack Hidley. NHT drivers and electronics surplus sale
AR 12" for $30 might be nice, but he isn't in Canada.

I rock the sealed box for the transient response.

I'm sure these other guys will come up with something great as well.

Thanks for your input. I appreciate it. I'll have a look for sure.

It is possible, but they'd be kinda strange looking.... same concept, 2 orientations. Top is probably better. The cats might like the bottom one.

Dave,

I'm really interested in the Trio12. From what I've read so far, sound's like a really good driver.
I'm worrying about my lack of phase adjustment so I'd like to have a front firing driver and a cabs serving as stands. With that in mind, I sketched the attached files as an alternative. Would it work? (One is the Original Shadow and the other is my variation1 for comparison)

Cheers,
PJeff

Now that is clever. I'm going to steal that

The only issue is that it doesn't seem to have the right throat for the start of the horn vent.

I'll have to redraw it to verify the details.

Thank's for the good comments David and AdamThorne.
That can be very easily adjusted for the throat... and the original drawing says that the ''suggested driver position uses golden ratio''. Not really knowing what that is, the driver position might have to be adjusted as well.
I'm really busy preparing and hosting my oldest daughter's birthday this weekend so I probably won't have much time to work on the fine-tuning of my variation this weekend. But as soon as I can I will adjust the throat and i'll be waiting on anyone's comment for further mods.

Dave, can you please tell me a bit on what exactly the shadow design does for the Trio12?

Thank you,
I got the feeling that this is going somewhere interesting for me...

Cheers!

I'm back with a possible solution to my variation about the throat dimension and it includes also the correction of an error I had made in the rectangular channel's length.
Do you think this is an equivalent variation to the original?

Can anyone help?!
