you guys know this already.

I guess anyone reading this section for the forum knows this. I finished a pair of Titan 48s loaded with Eminence 3015LF, and have used them on a couple of gigs with the band I run most often. They were replacing a pair per side (yes I know all about splitting subs) of Yorkville LS series 18's (total of 4 single 18s).
I was able to cross at 120Hz to a pair of EV Eliminator (orig. design), PLX 3402 power amps.

I'm a long time user of horns, including an all horn 3 way rig, so I was prepared for the result, but the band and regulars were not.

The overall impression is the mix is tighter all the way to the bottom. The bass guitar now has notes, not rumble. The kick is tight, with attack, and if I push it up in the mix, it still has plenty of presence, although not the same wallop as the front loaded 18s (with all the harmonic distortion). The band commented they could feel the kick in their feet for the first time, and the bass player actually turned down, because he could hear his notes better. There was not enough bass energy on stage to cause a feed back issue, however. Since the band is on ears, I don't need to worry too much anyway.

In all, I can get the same presence and excitement going in the mix, but at lower volumes overall. In the past, I was adjusting the top end to match what I wanted the subs to do, and that meant a pretty loud mix sometimes. Now I can add or subtract bass and kick, without changing the overall sound of the mix, just less bottom.

Since I am on a per show basis, I will not be lugging these to every gig, they usually are using their PA and I supply my A&H board and FOH effects rack.

However, they will notice when we go back to the Yorkies- and if they kick up some extra cash, I can be convinced to bring them every show.

The Titan 48 with the 3015LF is a great combination, and I recommend 2 centered or v plated, take your pick. That seems to be plenty for the 300 capacity room at country rock band levels.

I'll probably end up with 4, and mothball the Martin 2 15s per box subs I am currently using. Stupid things weigh about 250 lbs each, and don't go much below 60 hz.

That has been my exact experience with the T48's. I run them in many configurations often centered as recommended. I do have a few jobs though where they absolutely must be split although the split is 60-70' apart. I high pass them 18db/octave at 60hz. Plenty of low end for what we are trying to achieve at that gig and plenty of clean volume. The act is a swing era recreation with light drums (kick tuned high and open).

It is often revealing to walk 100' out from the system and realize how loud the bottom end actually is. Glad you are enjoying your new subs!

Matt, when you do a wide split like the above, how wide do you split your tops?

Are the tops over the subs, or do you keep the tops in closer to the talent?

I high pass them 18db/octave at 60hz.

The 56ft separation figure is 2x a wavelength @40Hz.

@60Hz, a wavelength is 18.75ft, so a separation of 38ft is sufficient to avoid cancellations.

The tops sit on the subs so the same split...the first audience member is probably about 60 feet away. At 150 feet I have a second set of small speakers on stands with lots of delay. Have a look here...I get to mix BACKstage???? This is why I am going to a wireless SAC setup...not to mention they are greatly expanding the number of inputs with more performers. The T48's do an admirable job of projecting some kick drum and bass guitar. It's not rock concert level, but it doesn't need to be either. We don't even have to push the small rig to acheive what the organizer wants. A lot of this is vocals too, the mayor, priest, and rabbi all get up and give their yearly reports/prayers. It's a community event

Almost forgot! The pattern on the top horns is so narrow that there is a deep null in the middle so people who walk up closer are out of the horn pattern from the mains. We usually throw a monitor down in the middle with just enough volume to make everything clear for people who walk up close. We tend to overcomplicate things at times, but this is a FUN event for us and we have LOTS of time to experiment each year.

Stack visible in front. Top is 2x12 + 2" 40 degree long throw horn. Titan 48 below. 3-way Amp rack behind. If i had more time to build otop 12's there would be 2-3 per side on top of the sub. I don't think we had the delay speakers setup yet..just a small set of yorkville elite m160's fed from an old Klark dn716 delay box.


No people yet, just finished line level checks. They surprised me with the whole additional band including drum set. Normally we just have the brass band which I can cover with a few overhead condensors. Don't ya love surprises?

get to mix BACKstage????

Fun ain't it
