Judgement day Titan 48

[bigtune]

Just finish my second Titan 48 yesterday and about to load the driver in and see what's all the hullabaloo about

[ewetho]

I know what they hullabaloo is about. Good deep bass (Misses only a few notes and some character sound you get in a T60 or older T36 or say the THT) that is monstrously loud and will carry effortlessly.

As long as you did your job (hopefully you got the 3015LFs too) you are in for a treat. Meyers, Martin, JBL double 18s or scoops you will laugh at. Welcome to live sound nirvana!

I load the 3015lf in the cab did a leak check and everything was okay. I then played some recorded songs for a few hours. The cabs are pretty loud but a bit boomy compare to my pair of QSC hpr181i. Maybe it'll get better over time but for now I am impress.

Nice looking build.

Explain "Boomy". Is it possible that you have them low passed to high say above 100Hz. I find that mine work best with a low pass of 100Hz. Any higher and they get Hooty to my ears. Bill, does cover this in his explanation of the horn's rising response.

They do sound different from 'normal' subs. as i was loading out my t48s from the venue the other night i had a listen to the Nexo ls1200 house subs playing the same music as had been through my system. even at low volumes the nexos sounded woffly (if that's a word)

Its difficult to judge subs without tops playing too. try them with some tops playing and a little more tweaking and report back.

[bigtune]

I hooked up my xti 2000 which I will be using for the T48 and low passed at 100Hz and high passed at 40Hz. The xti 2000 puts out about 48 volts before the clipping light starts to blink. I V coupled the cabs by putting a 4'x8' plywood over them and place the tops on the plywood to eliminate any vibration. The subs got about 3dB louder and noticeable deeper but the sounds is so different from what i am used to. It sounds a bit better when i am not turning the bass up at war volume. My next step is to connect the 204 Aural Exciter and Optical Big Bottom and have listen

I highly recommend you don't use that. Exciters can make a bad speaker sound better, but will only make a good speaker sound worse.

Nooooooooo! That just adds the harmonic distortion back in.

It sounds to me like you are suffering for some of the same issues that I had when I retired my direct radiator dual 21" subs for my T48s. I was using bass processors and such to get " presence". What I noticed right away was that the T48s were very clean but did not seem to have the punch of the 21s. What was really happening was I was used to hearing the loud harmonics of the 21s and with the Titans those harmonics aren't there. They are just clean pure bass. I have mine crossed at 100Hz upper and 35Hz lower. The Titans also require a different method of EQ. I'll try to explain but I hope Bill or Radian can chime in. You want to EQ the cabinet flat compensating for it's rising response by lowering, yes I said lowering, the bands from about 50 to 100Hz. Basically take the response graph for the Titan an plot the inverse on the EQ. Radain demonstrated this at the listening party on my T48s and WOW what a difference. I also learned, as Bill has stated, that important components of the bass sound spectrum are produced by the tops. They need to be EQd and up to the job. My 2way direct radiators that I thought were so good could not keep up. I replaced them with Otop15s and D&MN!
In short I used to have a loud PA. Now I have a loud and CLEAR PA.
It was just a matter of relearning everthing I thought I knew. You can follow some of the saga here http://billfitzmaurice.info/forum/viewt ... =1&t=12046 and our final triumph here http://billfitzmaurice.info/forum/viewt ... 13&t=12299

I have sold all my bass "processing" equipment on Ebay. If (and it's a big "if")I need more bass I'll just build more Titans.

+1

I do basically the same thing with my T39's....and how I wish been able to read that paragraph before spending months tinkering to get to the same spot. (...Not that I didn't enjoy the tinkering...now that I'm done...)

Listing to subs (especially these) without tops and trying to judge them is like someone offering you a bowl of cereal when they're out of milk

Pair it up with your tops and the game changes. It does take a while to get the sound you want, but once you do, you get so used to it everything else sound a bit muddy. Also, +1 on leaving out those processors. When you have a system that can truthfully reproduce what was recorded, then this is when it sounds best.

I dunno know. Cinnamon Toast Crunch is pretty tasty without milk! How bout Oreo's without Milk? Personally I prefer my bikinis without tops! But I digress subs without tops is just a very bad way to listen to subs. Also break in the drivers before you make any final decisions on the sound of any sub.

Thanks guys. Well, I have a gig this weekend and i'll be corner loading and V coupling them to get that infamous chest thumping bass. I will also EQ the cabs flat. After the gig I'll replace the xti 2000 with a 4000 to gain some headroom and hopefully better sounds.

The subs were tested with tops and drivers were broken in with a 30Hz sine tone @ 11volts for roughly 9 hours

So the T48 connected to the xti and xti to the mixer with a separate volume control.. How can I EQ the subs flat using the DSP on the amp???
My tops are powered and are control by the main mix output.

You need a laptop, and the System Architect or Band Manager software. if you don't have other Crown amps, just download the Band Manager software.
