What's up with the metal bit holding back the amp? It looks like just enough to wedge it against the top of the guitar stand, or it has a bump inserting into the stand?

It's a mike splitter bar that screws into the threaded insert on top of the stand. Stand height adjusted so bar stops amp sliding off

Genius, and so easy to make!

Cool. But $109 + $75 !! US/GB shipping. And where's the head go? This, £62 for stand, laptop stand and a tie down. But not quite so 'ansome.

You can buy the foam and make your own, cut it a little taller and the head will sit on top of the cab 

what you have works a treat  and is an instant fix though, I am quite lazy 😂🤣

Some of us are handy enough with a Stanley knife and some tough foam to cobble up a facsimile for a little less than that amount. 

[Downunderwonder]

Some of us have access to free double corrugate cardboard boxes as well.

 

If you have a recycling centre you can intercept the case off a broken obsolete electrical doofer, eg CD player, DVD, VCR, decoder. Plenty of material from which to fashion a Z.

My solution using the IKEA laptop stand. I it modified a bit 🙂 Removed some of the larger plastic lip and trimmed it round the cab corners.

Works a treat. The larger lip curves back on itself a little and is perfect for hooking over the front of the cab but I didn't like it covering the grill and speaker, hence the "mod".

That’s very smart and nicely done

That works so well it took me ages to even see it in the first pic!

That is very well done indeed.  Unfortunately I've had to hike my laptop stand up into the air (with 3/4 inch rubber plant pot risers) to clear the Barefaced handle, which is like a sort of suitcase handle, and probably is. So I can't be neat n flush like you. And if I trim my large lip back to where you've got it I suspect over time the edge will cut into the cloth grille.

You could always turn the cab up tall.

A Giraffe G42 stand will sort you out, can be set flat or tilted back. I used mine with a head/cab and had no issues:

I also used the Ikea stands when I switched to the Markbass wedge cabs, very useful things.

Have you tried this with the ABM cabs ?

I see the ABM600 head will fit and I might try it next rehearsal 

I guess it will be a few inches taller so might help 

[bassist_lewis]

I use big wooden hard cases for my amps so I put mine on top of those.

[BassAdder60]

So added four feet to the 210H cab using the same corner protector screw holes 

 

ABM600 head fits on it nicely

You should always turn the cab up tall. It doubles the midrange dispersion angle.

Always..?

I didn't think you were suppose tilt  cabs of the floor - something to do with floor coupling??

Can someone with technical knowledge enlighten me please?

 

Edit - I can see from a bit of googling, I've got that completely the wrong way round!

Like this?

 

It's made by a company called RTX, I got mine from Amazon, but it's available elsewhere (https://www.bax-shop.co.uk/amp-stand/rtx-trt-smx-monitor-guitar-amp-stand?utm_source=google&utm_medium=organic&utm_campaign=surfaces&gclid=EAIaIQobChMIhumU_Kil9wIVzdvVCh1Y2QofEAQYAyABEgJEDfD_BwE)

Yes. The dispersion angle in the mids is inversely proportional to the width of the radiating area. As shown that area is twice what it would be when rotated 90 degrees.

Boundary reinforcement from the floor happens when the lowermost driver is less than 1/4 wavelength away. At 200Hz that's 1.4 feet. At 100Hz it's 2.8 feet. There are instances where raising it more than 2 feet or so can be beneficial, as in the case of a boomy cab or stage where you want the lows augmented but not the midbass that produces boom. These rules also apply to boundary reinforcement off the wall behind the cab. Very often what makes for the best sound is the same thing that makes for the best real estate: location, location, and location.

Ordinarily, for a 210, sure, but the one in the photo is a Barefaced with one woofer low passed. For a personal monitor I doubt it matters.

 

The bigger problem might be the forward kick off the wall increasing.

[Bill Fitzmaurice]

That depends on where it's low passed. I suspect Alex did so fairly high, to eliminate comb filtering. Typically it would be done where the center to center distance of the drivers is one wavelength. With two tens that's in the vicinity of 1.1kHz. If it's done at too low a frequency the lost midrange output could be problematic. It would affect personal monitoring, as the driver that's full range should be as high as possible. The boundary reinforcement off the wall shouldn't be affected.
