XF Cab mod idea
XF Cab mod idea
First, there are way too few XF cab demos on youtube. I am thinking of building one. Like many others in the guitar community I have been looking at the Barefaced cabs and trying to figure out if they are for real. I have listen to them only on videos which I know is limited info, but I did finally hear a video that was made by a user and it did reveal that off axis the cab drops off just like any other cab. (big surprize huh) The other thing is I can't help but look at the AVD or Helmholtz resonator in the back and say uh it's a horn. Anyway here is my question, would adding a well designed "AVD" enhance the experience of an XF cab?

How are ay doin' Guido...
I'm going to take a WAG and say that no one here will be able to answer your question to any level of satisfaction.
Here's what I'd recommend; build an XF to spec. Use it for a while. See if/how you like it. Then modify it and tell us all about your experience. Oh yeah! Video... we need video!

It's not a horn, it's a tapered port. It's far too short to work as a horn. I don't see the need for it. Guitar just doesn't go low enough to benefit from porting. That's why you don't see it done.

Re: XF Cab mod idea
As a sound guy, I'm usually trying to get the bottom end OUT of the guitars - too many guys are trying to cover the entire frequency spectrum with one instrument.....fine if you only play solo, but it sucks when it happens in a band......same is true for keyboard players too.Bill Fitzmaurice wrote: ↑Tue Apr 21, 2020 1:20 pm It's not a horn, it's a tapered port.

As a guitar player, my ego wants me to be heard by the crowd....so, I typically thin up my sound and everybody can hear me....

Re: XF Cab mod idea
My XF 2x12 cab is at a friend's house and he loves the thing. Even sitting on the ground in a cramped 10'x12' room he likes it better than his marshall stack or mesa boogie. FWIW it has some old Alnico Jensens from an organ or something.
Just build one and try out different (matching) speakers. Where you located?

Re: XF Cab mod idea
I'm in Traverse City MI. I am going to build one. I just finished two Tuba 24's that I started 5+ years ago. They sound sooo good! I have more time now and should be able to get the XF done much faster. I just bought two Celestion TF1018's to put in first. I am using a Quilter OD200 and also need to figure out how to build in a cubby space on the XF210 cab to make it a combo. I may have to add height to the cab to include the OD200 on the top deck. Thank you Bill for the info on the tapered port and EQ reality. Thanks Bruce for the FOH take on the using guitar cabs live.
Re: XF Cab mod idea
I see Bill didn't put an airhead option specifically in the XF plans, but he did in the Jack.
I built an airhead Jack 10 as my first BFM cabinet.
It's pretty straightforward, just make the sides taller and put a top on it.
Top tip: remember to include the feet on your head when you measure it up, and don't block passive heating slots.

Re: XF Cab mod idea
It's gonna' look a little weird.....the cab is 24 inches wide and the amp is only about 9.....You could put little drawers on each side or offset it to one side and have a long drawer for pedals, etc....
Personally, I'd just throw that little amp into a gig back and be done with it.
Or, just build a vertical 2 x 10 combo. That would be a cool little setup....a foot wide and 2 feet tall.....it will look like a toy, but pack a wallop.
I built my Boogie Mark 5:25 into a combo with a single 12 that's only 15 inches wide and about 20 inches tall.....looks like a toy.....but screams....
In fact, I built one for another guy in my band too......baby Boogies....

Fabulous little bits of kit there; real sleepers.

You have two ears and one mouth. Use them in the same ratio!!
Re: XF Cab mod idea
Would the horizontal dispersion of the vertical 2x10 be as wide as the XF?
Re: XF Cab mod idea
And would it be easily heard standing few feet in front of it?

Re: XF Cab mod idea
A vertical orientation will have a wider dispersion than a horizontal orientation. The XF has a crossfire configuration to try and get back some of the dispersion lost by putting the drivers side by side.
I built an amp stand to hear mine better.....It looks much better than the tall metal stands.

Re: XF Cab mod idea
Ah, so what is good for a bass cab 250-500Hz (ie. clarity) could be a problem for electric guitar (muddiness). Thanks!

Re: XF Cab mod idea
Well, tone can be achieved many ways......if you rolled off at 500hz....it would sound like crap. I typically high pass electric guitars from 100-150hz. It still depends on the EQ coming out of the amp. You can't fix a bad sounding amp at the board.
