Upgrade-itis - UPDATE Subs are done!

[mattp]

Wouldn't you know it. A pair of UM10's with 1900 watts and a ton of DSP can't handle output below 30 Hz

It was never a concern when I lived in an apartment but I knew it would be an issue once I was able to actually turn my system up and not piss off the neighbors.

So...that leads us to the new subs

These are the first cabinets for myself that I didn't feel like building so I recruited Scott Campbell, a local CNC dude. I drew up the plans, sent him the CAD files and a few weeks (and a lot of $$) later - here we be. Overall dimensions are 27"H x 28"D x 22"W. 1" MDF shell, 2" baffle, 3/4" bracing all dado'd. They haven't been weighed but I am sure they are close to or over 100 lbs unloaded. They used close to 6 full sheets of MDF to build. I think you can understand my lack of desire to cut and assemble these myself.

They will house UM18's, sealed, roughly 7.25 cubic feet for a Q of about .65 (IIRC). Powered with a Behringer EP4000 and DSP via an FBQ1000. This is the setup I've had for a while now and works very well.

Will update with finished pics, this is where they stand now until I close on my house. No point in moving them more than I have to...

Oh you might still piss off the neighbors.

[bullittstang]

Your neighbors will be asking "where's that thunder coming from...it's clear blue sky outside????"

[mattp]

All in the name of clean dynamic output. That's all I'm really shooting for here

Although pant leg moving infrasonics are also fun.

lots of fun !

Bro, that's harsh.

Holy crap, the mother of all Subwoofers! You're going to have to breathe in phase with the music!

[jhollander]

Might as well add the casters now...

[joeybutts]

Ooooooo you are giving me the urge to rebuild my 18's.

Beautiful cabs. Can't wait to hear how they perform for you.

Dooooo iiiiittt........

I don't remember which 18's you have come to think of it.

[Kevin K.]

Nope, no worries about pissing off the immediate neighbors, now it'll be the ENTIRE neighborhood. Should be epic!

I really should, they are incredibly undersized....Elemental Designs 19Ov.2's sealed in I believe 2.25..... The problem being that the actual circuit of the house can't handle the draw...I've tripped the breaker a couple times. so if I went twice as big they'd really put a hurting on the room.....

along with 13Av.2's.....


I'd have a hard time letting go of those cabinets I built though...... I put some time into those things.

Now load those cabs!!

Throw those ED 19's in about 5 cubes sealed. More efficiency on the bottom end. Plus I assume you're using your 13's for mid-upper sub bass? Are you using any DSP or just letting the room do it's thing? If you arent using DSP I would HIGHLY recommend you throw a MiniDSP on those. You probably won't have to rebuild anything.

They will be loaded soon enough!! I just got done putting in the Speakons and getting the cabs stuffed. I just need to get them in the house before I throw the woofers in. That hole is a nice hand hold and there's no point in adding 35 pounds to something before I inevitably have to move it lol.

Wow. I was thinking about going with a 12” but thought it might be overkill

Stephen...there is no such thing when it comes to subs...

You can always turn it down - and then let the 12 year old in you show himself when the wife is gone

[tomzarbo]

Yikes!!! But in a good way.
