Ahhh, I see your edit. You got the "Hot 100". I was thinking you got the K-100. Um, just see how it goes. I'm not trying to dog on your speaker choice, but if it were me, I'd send it back.

Ha! OK. Fair enough. I've been warned!
 
It's a 65 watt amp so not really.
I may or may not send different amps to it though, so I figured I'd leave room.

Still, even if I had an 80/100 watt amp going into it, I'm never going to push it that hard.

Yeah leave some room. I suppose a 100w speaker would be warranted in a 1x12 with that amp.

I would think something from the Eminence Patriot/Legend lineup or Jensen would be better for a Fender kind of sound.

Ok, thanks. I'll keep that in mind.
I have a couple of pals who may consider a swap if I don't like this driver so that's something.
 
Well, the driver arrived today.
I don't have the amp yet and I sold my blackstar, so all I have to test is the little DIY deacy amp.
I also don't have all the wood to build the iso box yet. Most of it's down at my brother's.

I've just plonked what I have together cos, why not? :p
As you can see it's going to be pretty small.

The 8" in the deacy amp sounds like this
and the 12" as pictured sounds like this.
I'm pretty happy, so far. :)

I'm often through Watford way. I'm gonna call you up one evening and we can hit the town.... Well Bushey or Shenley maybe..:thumbs up:
 
No real plan. It's just gona be a tight fitted box, siliconed along all the joins, bucked in a pit!
The pit's about 6'x6'x3' or so and the boards which cover it are about 2" thick.

I think/hope it'll be enough.

Who is Mutt talking to?
Edit: Forgot this isn't my thread.

Grim, I forgot he was Watford based. I'm in Herts too and regulaly drive round the M25. He's less than an hour away.

I know it's an old thread but he's bound to check it now it's been necrobumped...

So the pit itself is actually the iso box, what you're building is a closed cab. Am I imaging that correctly?

No. In the picture (did it show up ok?) you have two sides and a divide with the speaker on it.
I'm gona put top+bottom, front+back on that, seal it up, and that's my iso cab.

The whole thing is gonna get thrown in the pit just because it's there and unused. That's bound to help.

Right, I guess this is just semantics, but that's not really an iso cab. It's just a closed cab being placed in a pit. It's sort of like a traditional iso cab, but you haven't said if you're adding any sound control inside of the little cab. The pit itself is providing your isolation if ambient sound control is the goal. The little cab itself will still be pretty loud, it's just gonna be kind of sealed off in a pit. Theoretically, a typical iso cab wouldn't need to be put in a pit because the cab itself would provide the outside attenuation you're looking for. Like Grim's acoustically treated box-in-a-box at the beginning of this thread.

But whatever, it's a cool idea and seems like it should work just fine. I sometimes wish I had a big ol pit for my cabs. :D

I duno. I think there's crossed wires somewhere.
I'm pretty much building the same thing as minerman did.

Where Grim's is a box in a box, mine's going to be a box in a pit.

The mics will be contained inside one half of the wooden box. I'll probably line the insides of it with some kind of insulation if I happen to find some.

Right, okay. I get that. But I think, I might be way wrong here, but I think Minerman's cab in that picture goes inside of another acoustically treated box too. I think his is a box in a box. The space between the two boxes and/or the treatment in either box is what provides the isolation.

Or it could be something like the Randall iso cab. You might wanna port the baffle.

I'm not at all saying what you're doing is wrong. I'm just trying to wrap my head around it. I'd like to hear what you think about the closed box vs a regular cab in the same pit.
 
Ah, I see what you mean. That makes sense.
I'm doing what you pictured, give or take.

Unfortunately I don't have regular cab to throw in the pit and test. I did try it a long time ago and it helped a bit with isolation but the recording didn't sound good.
I suppose a 6'x6'x3' block pit isn't ever going to sound good. :p
I thought about just lining the pit with rockwool and getting a combo amp or 1x12 cab, but that'd be a pain in the ass the next time I need to replace brake lines or something.

Lol. Yeah, I think I get what you're doing. You wanna use the pit to potentially cut down the loudness projecting out into the rest of the world, but you wanna isolate the speaker/mic from the horrible sound of the pit. Is that right?

If that's the case, and I know you already started this, but I'd suggest you make that cab as big as you can while still being practical.
 
Ps. I know Grim hasn't been around, but if anyone things I should start my own thread please let me know. :)
