New BassChat 8"Cab design

Let me dig them out and I'll send them down. DM me your address please

Started on the second cabinet today. 

 

This is a dry run fit, so no glueing. 

 

So much faster when you have done one before. The panels were all cut a few weeks ago, though I found one end was at an angle. Suspect the circular saw was poorly setup by some idiot.

 

Rather than cutting the batons in advance, I cut them as I needed and used a mitre saw and block rather than a home made table saw. This was a far better way of working and wasn't much slower.

 

Just under two hours to get to this, I do now have frostbite, but well on the way to getting a second cab, so completely worth losing a finger or so, who needs a little finger for playing bass.

 

 

 

Front and rear faces are also cut and fit, but I haven't done the holes for the speakers, handles etc yet.

Coulx you pop round and finish my aquarium hood? When you've got a minute.

No problem at all. Be happy to, whens good?

Is there any benefit to putting this speaker on poles at all? I happen to have a pair of Quickset Hercules tripods for astronomy use. These will easily take 40Kg each and probably closer to 60Kg without breaking sweat. 

 

No idea how to, but thats a different problem to solve...

Fit a “top hat” to the underside.  Sorted.  I’ve got one I’ll never use if you want me to pop it in the post, Rob.

@Pea Turgh 

 

Thats kind of you. At the moment, I'm just wondering it it makes any significant difference for the better to put them on top of something. I have a recollection that somebody said they should be on the floor in a corner but can't find the comment.

 

If I had the "top hat", I'd still have to fashion something to attach to the tripod. Yet another adapter

 

Hold off for the moment please.

Raising a speaker creates position-dependent dips in the frequency response where the reflected wave at a given frequency combines out of phase with the direct wave at your ears. Walls and ceilings also do this. Hence in-room response measurements can be pretty crazy.

 

But it has the advantage that it puts the mids/highs a lot closer to your ear! Sometimes that matters a lot more in practice. It depends if you want more note clarity (raise it up) or girthy bass (shove it on the floor next to the wall if not in a corner)

Dedicated speaker poles are so cheap it's not worth making an adaptor and riskinc a nice astro tripod.  About £20 on Amazon. Gorilla only £24.

Didn't realise they were that cheap. The 'adapter' would be metal rod or a piece of wood and the tripods have already been adapted. They came with the slo-mo heads on and I took those off made plywood plates to fit various EQ heads. They are rather battered from before I brought them, but were probably very expensive as they were made for Hollywood type film cameras . I know the model or or two up from mine was $12,000. That's mine below.

you'll find that speakers sound very different up on poles. any hard reflective surface will reinforce the bass frequencies in particular and you'll get an extra 6db for each reflective surface. Spacing something away from a surface creates two paths to the ear and you'll get a time delay between the reflected sound and th direct sound from the speaker. That creates points in the frequency response where you get cancellation.

 

I use the same speakers up on poles as PA and on the ground as floor monitors with one of my bands and DI the same bass signal into both. I don't use backline. I have to cut the bass to the monitors by at least 6db or the bass frequencies just drown out everything else on stage, the same signal is crystal clear out in front of the stage. Whether that bass reinforcement is good depends upon what you want to achieve/like. The 8" cab you've built gained a lot of love sitting on the floor but you can experiment with it on a pole. The best stand of course might be your other 8. maybe a stack of four would sound good

 

I've used my 6" cab for open mics. It doesn't have the bass of the 8" cab so I tend to find a corner or a rear wall for it so I can use the bass reinforcement. It's good to experiment and you can learn to use the reinforcement as an extra tool.it's free bass boost if you need boost. A real nuisance if you don't.
