AL-III.....Owners...

You probably aren't getting much stereo separation in the bass region

You never stop do ya....!!!!...as far as imaging....?....exceptional...(not through the subs)..what...do you think im stupid...?..ok dont answere that....

Just pulling your chain

Welcome back jvds.

Great to hear the STG working out so well for you Steve. I was thinking about getting one when I build my next system. They seem to be available fairly inexpensively too which is always a bonus.

Thanks man, I got my STG II of craigs list here locally....it came in the box with all the packaging and the glass for 400.00...

Wow Steve what a great deal especially with the box etc.

I have the III, and mine can go past 150Hz. I'd up that crossover point to 150Hz to get the most out of your speaks (on small). That way, the ribbons will be getting 150Hz and up, and the woofs will be getting 150Hz down. That is a great idea for those with a Sunfire Theater Grand. You can use the adjustments on your real subs to block content above the desired frequency (say 80Hz) Gary — are you paying attention here? You don't need a Rane!

Well Bill, I tried this~~but I'm not certain yet if I like it or not. It's taken a LOT of dialing of the sub & low end of the AL-IIIs to try to get it to sound right. In this configuration, the sub adjustment in the TG-IV affects the mains low end as well. I've had to adjust the TG-IV to get the low end of the mains sounding right (not sure I'm there yet) with 150 hz crossover, the mains set to SMALL, and then adjust the sub with it's internal digital adjustments. Since the sub is only handling the lowest notes the AL-IIIs won't hit, it's crossover is set to 40 hz with a 48dB/octave roll off, and I've got it running down about -8 to -10 dB from reference. The entire setup will get a LOT louder this way, but it almost seems like I'm missing something in the high bass range. I need someone to put another set of ears on it and tell me what they think....any volunteers??

If your mains are set to small, the sub will get everything below the crossover point. But since you're throwing away everything above 48Hz, that's all it will see. Your mains should have a big HOLE in the bass. The real problem with this setup is that all the bass will be mono.

Yer not gettin' me; the sub & main woofers are all running out of the SUB preouts with the same crossover freq (and it's 40 hz, not 48 hz)! Everything below 150 hz is going to both the main woofers & the sub. I'm cutting everything above 40 hz to the sub with it's 48dB/octave internal crossover. It's adjustable from 40-120 hz internally with 18, 36, and 48 dB/octave roll offs. Everything from 40-150 hz is being handled by the internal AL-III woofers.

But the sub pre-outs on the Sunfire are MONO. Sorry I confused the crossover slope with the frequency. I;m still confused, though. You say in one sentence that everything (sub and main woofers) are coming from the sub pre-outs which are crossed at 40Hz. Yet the next sentence you say all frequencies below 150 Hz are going the same place.

Now if it's the latter, which I expect it is (Sunfire TGP crossover at 150Hz, and sub crossover at 40Hz), there will be no hole, but the bass will be mono between 40Hz and 150Hz. Above 80Hz, you'll probably detect it as something missing.

Yes, EVERYTHING below 150 hz is coming from the sub preouts (3 of them) and going to either the sub or the L/R speaker woofers. The full 150 hz down to 0 hz is being fed to the Mains woofers and the sub; however, the crossover at 40 hz is being done INSIDE the sub which affects ONLY the sub. You are also correct that the information being fed to the woofers is MONO. I understood that limitation when I decided to try it.

Now if it's the latter, which I expect it is (Sunfire TGP crossover at 150Hz, and sub crossover at 40Hz), there will be no hole, but the bass will be mono between 40Hz and 150Hz. Above 80Hz, you'll probably detect it as something missing.

In fact, this configuration makes the bass mono from below 0 to 150 hz. I find it hard to believe that small band of high bass could make such a difference being in mono -vs- stereo, but apparently it does!

Clear as mud?

¡SI!

Damn~ I can definitely rock & roll with the new Amazing setup! A good 4-6 dB over the old max...

If you have good Karma and get a Rane AC-22b, you can do the same thing (with stereo bass).
