    PM 60 & 90 settings and alternative drivers.

    Hello all. I'm looking for original PM90 settings for a 16ohm BMS 4594 & RCF Horn HF950. I do have the 2-way crossovers.

    Port Holes on Horn Walls

    hehe wow. Ok, so is there some kind of extension connecting the compression driver to the horn? I'm imagining a pipe from the horn entrance to the dust cap. I would have never thought about doing something like that.

    Port Holes on Horn Walls

    Thank you for the input. I learned a few things here. I went and looked at some other Danley products and their column speakers seemed interesting. They use coaxial drivers inside a horn but through a paraline system. Obviously, this works but a lot more complex.

    Port Holes on Horn Walls

    Hmm, views but no comment. Maybe a picture would help! I want to use a B&C 8-inch coaxial. The problem I see now with putting a port on the wall is that I would have to include all that area between the horn wall and the outside wall. I also thought about the 1/4 wave rule. If I wanted to say...

    Port Holes on Horn Walls

    I'm sketching out a plan for a dual 8-inch horn. I wanted to port to get some lower frequencies - not wanting to use a sub for things like basic voice PA or wedding ceremony PA. Is there a rule about putting ports on the horn walls? Would it even make a difference versus a port say on the...

    Outdoor Speaker Cabs for Pyromusical

    I'm doing more and more fireworks to music gigs and am considering building a suitable speaker system for outdoor use. Like most of us I really dig good music quality, but in this case superb sound is not a requirement. That still doesn't mean it should sound like garbage. Decent sound is good...

    Double 10 and Horn

    Actually, I don't think I was way off. I went back to Peters first post and he states he's using 40L for both drivers. Is it safe to assume 1 driver would get 20L? I'm building an MTM as well but I'm going to add a plate amp so I'm enclosing each of the 10's in its own space by adding some wood...

    Double 10 and Horn

    I have a similar issue with the ports. I thought, well, why not put them in the back? @Max -- Would you mind exposing what speaker software your using? I'm using a cheapie and unsure about what it's telling me. It's recommending that the enclosure volume for the 10NMB420's should be 15L. Got...

    Double 10 and Horn

    I was looking at using a plate amp to build into the cab. I found some decent ones with built in DSP but most lack in functionality. Here's a screenshot of the software from one of these amps. Do you guys think this would be enough to setup the cab? In the high pass/low pass xover section how...

    the LEAP experience

    I wanted to get some feedback about this software. It seems somewhat outdated. There are no updates for current Windows or Mac OS. When I inquired to Linearx they are vague and only recommend their analyzers to use with LEAP. However, their analyzer LX500 has not been released and it seems its...

    Double 10 and Horn

    Thanks David. Because Peter had set his horn to play at 650Hz I used that frequency in the wavelength calculation. If I got it right, you can see from the attached the 10's start to overlap into the RCF horn lip. The 10's are about 260mm from the horn's center. The RCF HF950's cut off frequency...

    Double 10 and Horn

    I really like this layout. Reminds me of a boom box. Wish I could fit it into a 30-inch width (thinking...)

    60 Degree DIY Mid Hi - AKA PM60

    Hi again all. This DIY is intriguing. What I like about it is that it seems great for outdoor gigs. Some years ago I got out of DJing and got into pyromusicals. For a pyromusical you need to have speakers that perform well outdoors. I've been renting JBL line arrays for this purpose, but...
