    Looking for lightweight active 10" speakers

    The Altos are not going to really cut it certainly for 400 people. The Yamahas you mentioned earlier are possibly your best bet, they make a lot of noise for their size without sounding bad, but with a band (assuming some bass instruments, drums, etc) and 400 people you will need subs. In...

    X32-s32 drop out

    Thats likely your problem, particularly with your description. It happened to me until I borrowed a fully shielded cable and then bought my own.

    Ever need to record saxophones? Not the most obvious instruments.

    So many choices, but one or two microphones, two being over the keys and one on the bell, I personally prefer only 1. 414, U87, at 4050, royer, 4038 Cole’s a good choice. Dynamics, 57, 57 beta, Beyer 88, Shure 58, 441, 421. Best advice is to think of it like a voice and don’t just stick it...

    New DIY Mid High (90deg) - AKA PM90

    They breath better. There is no perfect sub, but tapped horns and some horn subs do ok. People like KV2 make great bandpass boxes when most around are pretty horrible. Good design is good design.

    Indeed that’s what I use.

    New DIY Mid High (90deg) - AKA PM90

    It’s a bit of both. I don’t complain about J subs or KS28’s but these are pretty much top of the tree. Most have problems with port chuff particularly with modern high powered drivers or those that are pushing the envelope. Horn systems, 1/4 Wave systems tend to be more forgiving of being...

    New DIY Mid High (90deg) - AKA PM90

    I I have a variation that I built based on these. Tapped horns are a nice solution. I find a lot of reflex boxes a bit hard going these days. There are some exceptions the L’acoustics KS28 being an example. I also like the dual 21”s KV2 make and their 2.5’s which surprised me as most...

    New DIY Mid High (90deg) - AKA PM90

    Peter originally used Dolby lake, but I believe he now uses the Linear Research ASC 48, or the amp equivelent. I have mine run on the Linear Research, 48M20. The obvious benefits are these all include FIR filters. You could do much the same with powersoft and their Armonia software. Various...

    New DIY Mid High (90deg) - AKA PM90

    At the risk of veering sidewise, I’ve got a Linea research 48M20 on evaluation at the moment. I’ve got to wire a patch panel and install some settings and take measurements. Will be using it in anger over the 22nd - 24th of this month. Will report back on my experiences if anyone is interested.

    I’m sure you are using the same pdf we started from, and the width is 398mm using 15mm ply.

    Ported Sub to Tapped Horn. Questions before starting

    The cab should work given the right speaker. My only reservation is that it may be tuned a tad low. You need a speaker with an extremely stiff cone and decent Xmas.

    Very well. I do a number of events for my local council each year, but much of my work is for bands. I’m lucky in that all my clients just trust me and I can use what I want. Never had to make a rider for my direct clients. I have another client who is all named brand speakers, d&b...

    New DIY Mid High (90deg) - AKA PM90

    Mine are 4 way active on cheap Chinese plate amps, but I’m hoping to run them with Linear Research amps in the near future. My ver of the TH118, is tuned slightly lower than the xoc1 version. I get pretty strong output to 30hz, low enough for live, not really planning to get into EDM, but I’m...

    Here is another one. It’s a bit windy and reflections take the edge off the quality, but it gives an idea.

    New DIY Mid High (90deg) - AKA PM90

    Just thought I would post a video of my PM 90’s from yesterday. The video is taken from between 70-100ft as I move backward, with a galaxy S7 phone. Subs are similar to the xo1c design, but I made changes to the internal design and layout. Track was playing at around 82-84db from where I was...
