Re: Low cost Class D pro plate amps.

Enjoying the discussion so far! I was toying with the idea of a plate amp recently for my subs. I picked up a salvaged plate amp from a JBL SRX815P cabinet a few months ago for $50. I estimated that I could run up to (4) T39's off of it, but I can't install it in any of my current cabs. So, if I bu...

James Champer,
You can produce radio shows streaming to youtube like this, where you pan zoom and live cut from camera to camera ?

Re: Let me introduce you to "THE KRAKEN"

Here's a video clip, with pretty decent sound, from that exact sound system, at night, with fire spinners, watch the entire thing, the cameraman walks from far away up to the front.

Re: Crossover frequency does matter

It wouldn't be of any use as I would EQ every system to sound as good as could be. There just isn't the time or inclination on my part to do this properly in a non-reflective setting with three different systems. Anyway, those graphs are available on the internet. I'm just making a subjective analy...

Re: Low cost Class D pro plate amps.

Grant, about pricing and product, your feedback would be a help: Which features would you require? Which features would you like to have but not absolutely require? How much would you be interested in paying? I've tried to say more than once elsewhere here in the forum I'm not interested. Unless th...

Re: Crossover frequency does matter

Well, it's a slow Easter Sunday here on the forum.....so, I though I'd start a little discussion. First, an observation concerning different speakers in the same room. I have run sound in a particular venue here in town several times - pretty evenly split between a rented system that a provider bri...

Re: Duratex alternative

What's a "competitive alternative" to Duratex, in other words, 1. same or similar Polyurethane Acrylic paint formula, 2. from a different brand, 3. for a cheaper cost per gallon. Based on all the guys building cabs on this forum over last several years and constantly looking for an altern...

Re: Low cost Class D pro plate amps.

Thanks for your replies Grant and NukePooch. EDIT: There exists an advanced version of switch mode power supply, which puts out steady power and voltage, even when the AC mains sags.

Re: Low cost Class D pro plate amps.

Question for everyone: Which is better - as in, less of a BAD THING - to have. Given a Class D pro amp with a modern switch mode power supply (it doesn't care input voltage as long as it's 90 V AC - 300 V AC): 1. Voltage drop in the MAINS AC CABLE feeding the power amp, due to slightly long mains AC...

Re: Low cost Class D pro plate amps.

Powered SOS (speakers on sticks) are convenient when you just want to throw 2 up for a few hours. They are a PITA when you need to run power to a bunch. We run an 8 cab PK rig and running power sucks every time. Troubleshooting on stage in the middle of a show when an outlet gets overloaded, or the...

Re: Low cost Class D pro plate amps.

I would have to see the design details to comment. However, the path of the DR280 is 3 feet. * RCF and (if I remember right) JBL make horn loaded compact line arrays. Probably several other makers also. Here's one of RCF's the HL-2290. This is just one example, not saying this is the best example a...

Re: Low cost Class D pro plate amps.

Would there be no value in making a 14 inch tall, 32 inch wide, "compact line array" cab design? Similar to offerings by RCF, JBL, Meyer, etc. None. They make them low and wide because they use dual woofers. They use dual woofers because being low sensitivity direct radiators they have to...

Re: Low cost Class D pro plate amps.

This pro plate amp opportunity could be the perfect new cab design opportunity for BF, to design a new pro style LINE ARRAY CAB - short, wide, stackable with the special external steel hardware, with the tweeters on wavefront horns! Competitive with the big guys We already have that in the DR serie...
