I would still do the external speaker processor and aux-fed subs though.  125Hz is a little high for me on an 18" sub.

Okay I haven't been aux feeding the subs.....am I right in thinking the purpose would be to control the volume of the subs separately to the volume of the tops???.......I've always used the volume control on the back of the sub and main speaker....then gone out of the desk via XLR to the sub and used the high pass output to run the tops!

If I aux feed the subs and feed the tops.....how do I cut the bass frequencies from the tops??....or should I be using a crossover for that reason??

Cheers

Well.......not really much of a constructive answer...

Nick, But it is constructive, I'm trying to save you wasted trial and error and euros, if you stay in this field for any length of time (if you are good at it and you have demanding clients) you will eventually realize that the lower level gear, even if deployed correctly, will not suffice, as exemplified by the SRM450V2s

Id Cheer you right back but it's 10AM...

The DSR has a high pass built in.

So we agree.  Wanna join Geezer Audio Services with me, Rees, and Leonard? (Larry, Moe, Curley, Shemp)

I'll join.
Had a drummer a couple of months back wanting vocal, snare and keys in his monitor.
12 x 12 stage, in a 300 cap "ballroom"
Vocal, well, ya. Keys, sure. Snare, Really ??

Aux fe subs are used as an additional way to control what the subs are actually getting. A crossover does this by splitting the frequencies that go to different places. Aux-fed approaches it by only sending items that NEED to be in the subs to the subs. So, you might not send vocals to it, but your kick/bass/etc are sent to the subs. Pop a crossover in to LPF the tops to handle those lower frequencies in the mains.

But Mike did make a good point as to the overall professional level of the gear. Yeah, 450s are OK, but the next step is really going to be going to the next level of gear.

I'm about to go out and buy a pair of Yamaha DSR112 this week then

Will that give me a good level of professional gear quality???

....essentially will this give me a sensible step up?

Aux-fed subs also keep the vocal mics COMPLETELY out of the subs, something that no "lo cut" or 18dB/oct @ 80 or 100Hz filter on the mixer channel strip can do 100% effectively.  And boy on cheapo mixers those lo cut filters really cause phase shift and muddy up the vocal.  I just leave the lo-cut disengaged because they never make it to the subs with aux-fed subs.

Speaking of MI-grade gears like Mackie...those original SRM450 that were made in the USA or Italy used high quality drivers and were pretty darn good.  Would the DSR112 fir your bill?  Wood cabinet is a good start.  I think the issue is they can get away with cheaper components and compensate/correct via the DSP.  So end result is it does sound pretty good, but is it going to last?

Is it going to last???

....so what should I be looking at??......I honestly have NO idea here....I am new to all this

[nicklang]

Also assuming I'm gonna aux feed the subs.......

Do I send:
bass guitar - Kick drum - floor tom
to the Subs ONLY

and send:
Vocals - snare - high tom - mid tom - cymbols
to the tops ONLY

Have I got the right of it??

Also is there a delay between the two different output signals??

Is it going to last???

I see from this website UK customers do appear to get the rather generous 7 year warranty! This would imply that used correctly, Yamaha do indeed think it is going to last
