Re: TLAH and SLA theater

You don't want surrounds to have too much high frequency content that makes them easily located, and the same applies to overheads. I wouldn't use tweeters.

Re: TLAH and SLA theater

I'd do the two driver surround version, aimed either down or at the listening position.

Re: TLAH and SLA theater

I'd use single Goldwood woofer boxes and not bother with tweeters, there's no reason for them in overheads.

Re: What's to chat about?

Last week we had a house jam with the guitar player using a Supro 5 watt tube combo loaded with an eight. It was plenty.

Re: What's to chat about?

Look at the frequency response of an electric bass speaker, then the frequency response of a sub. The only way you get what's coming out of the sub to sound close to the same as what's coming out of the backline is with some serious reduction of the low frequency content in the PA channel, and proba...

Re: What's to chat about?

I've read about acoustic guitars and acoustic bass guitars feeding back and possible solutions for the Ovation. But, haven't been able to find anything on hardbody bass. In the two or three times it's occurred, the bassist was less than 6 feet from the subs with no option to put more space between ...

Re: otop with only dsp?

The primary benefit of bi-amping was when amps were small, and when used with low sensitivity direct radiating systems they were pushed hard enough to have high THD, heard as distortion in the highs. I don't see it being useful for OTops unless you're running more than four of them, in which case yo...

Re: Comp Driver OT15

The 15MB 700 is OK, but not as good as the 3015. You may be able to find them in stock somewhere. Even if you can only find four for now that's a good start.

Measure it on your sketchup model.

Re: Omni 15 2x12 with Beyma Woofers

Yes, the hump is from the box size and tuning. I would be inclined to go with an 012, say 27 inches wide to fit the two woofers.

Re: Omni 15 2x12 with Beyma Woofers

They'll work. Compared to the 3015LF they have a response bump down at 38Hz. They wouldn't be bad in a O12 made wide enough to accommodate them.

Re: Jack build European material

1 no tweeter, 1 low tweeter (4 ohm resistance in serial on the high pass filter input), 1 full tweeter (direct input on the high pass filter If you're saying what I think you're saying don't do that. There is a 4 ohm resistor in the high pass filter. Another 4 ohm resistor in series with it will ha...

Re: Otop 8 future build

If you had the plans you wouldn't need to ask these questions. You shouldn't even be thinking about ordering anything until you've read through the plans at least twice.
