Re: upstarts needing amp info.

Hey Nancy, Can I recommend you keep the table tuba/TLAH question out of the equation for a little while, just until you settle your primary build. You asked earlier if there was more to consider, and the answer is, yes, always :) But to make it a little easier, I have been purposefully drip feeding ...

Re: upstarts needing amp info.

We know that Grant Bunter, Corona Operator have differing opinions of tops to sub choice Let's explain that. CO is way more familiar with the real world requirements of reproducing EDM via a PA system than I am. Experience in that field has left him with his recommendation of a ratio of 3 or 4:1 su...

Re: upstarts needing amp info.

Best to avoid long extension leads. Under heavy load they may melt/get hot/catch fire. I would (and do) use one to say a maximum of 100ft (but the load on it is very low). Even then, I remain leery of available power at the business end, as long cables lose power over distance. Better to have a larg...

Re: upstarts needing amp info.

2 x DR250 and 4 x T30 isn't a bad place to start IMHO

The great thing is, you could build that, and if you find it isn't enough, you can add more...

Re: upstarts needing amp info.

Nancy, It's imperative that you build what you need, not what you think you might need lol. There's a bunch of decisions to be made there alone, and you need to be adequately informed to make those decisions. That's why both CO and I are trying to inform you, you probably don't need T60's, though th...

Re: upstarts needing amp info.

That's an impressive list :) Read Corona Operator's post, it's very handy! OK, let's see if you actually need 20-25Hz. If you have audacity (if not, download it for free) and work out how to use it to evaluate the lowest notes in the most bass heavy songs in your list. If you find 1 or 2 songs only ...

Re: upstarts needing amp info.

Hi Nancy (and Richard), Welcome to the forum :) "Dance music" is too generic, one of Bill's quotes is Without a doubt the cab most often built that probably shouldn't be is the Tuba 60. It's only a good choice if you need a lot of output below 32 Hz, and the vast majority of users don't. This is bec...

Don't second guess this.
Go direct to Eminence and ask them!

It may simply be they are about to do a production run of Lab12's....

Re: Driver Advice

I did not see your post until after I had posted my first initial post. You did not account for impedance raise of the cabs, I would personally run the smaller amp on the lower 4ohm drivers. To save moneys. I thought Grant had suggested running the bigger amp off a higher impededance, if money is n...

Re: Driver Advice

those amps do 1000w and 1500w respectively at the 1% thd not quite as much as they so boldly advertise. you have to read the description to see their trickery. I agree with Grant, get the bigger amp and the higher impedance drivers for best results!!! Your two posts contradict each other. :confused...

Re: Driver Advice

You don't need the db15, according to it's specs, the db14 will put out 63V @ 4ohms, more than enough to blow your drivers. 2 x 8ohm KL3010lf's in parallel will present a 4 ohm load to the amplifier. Any amp running at 4 ohms will have a lower power draw than the same amp running at 2 ohms. Since yo...

Re: 1/4 inch connectors: airtight?

Speakons were created to prevent accidental disconnects.
For that reason alone, stick with only speakons.
Then the issue of airtight 1/4 sockets disappears ;)

Re: Kreg screws?

Welcome to the forum :)

Sure, use Kreg screws if you want.
Stick to the plans, and use 1/2" ply. If 3/4" ply was necessary, it would be specified in the plans.
Using anything other than 1/2" ply, from the outset, requires redrawing the plans...
