Matrix, a British company, builds a solid state amplifier intended for installation in guitar cabs, called the GM50: http://matrixguitaramplification.com/products/gm50/ I have no experience with it, but looks like a well thought-out design... in fact, I was considering using it in one of my own prod...

Very nice job Jim, and thanks for posting pics & descriptions of the process. I use Duratex in my business on a regular basis. You can also vary the texture by how much water you add to thin it, and if it's a hot/dry day, you may need to thin it anyway to give you adequate time to cover a whole ...

Designing directivity-modifying lenses isn't all that hard. Audible sound is just a "mushier" form of waves compared to light-waves, so you can model and design [reflective] lenses for lightbeams and get them pretty close for mid/high freq soundbeams. Building them ... is another matter e...

One way to improve on radiation uniformity over the frequency range, is to "hornload the speaker". Getting horn dimensions and all angles just right is critical for the desired "spread" effect, and the total cabinet depth will have to be increased quite a bit compared to the ave...

You got it right Duke, on stage it is very top end , almost telecaster type cut your head off high, but out front (about half way down hall it sounds nice , not too much bottom or top , but enough top to cut through mix.this of course when not going through PA,when going through PA I set it to soun...

My understanding is that the electric guitar guys who are using the Kemper (and/or other modelling preamps) are gravitating towards "full range flat response" (FRFR) speakers. This is because all of the tone coloring they want is provided by the Kemper, and so amplifying that signal throug...

Duke, amps concerned were Nashville 400 with 15inch Black Widow, Profex/DPC/15 inch Nashville cabx2,Nashville 112 12inch Blue Marvel , GK MB200 amp with 12inch Sica neo in cab built to specs used by Steve English on thread about MB200, found similar results in them all.As you say,have to compromise...

My solution was at rehearsals to set amp up in normal stage position but set steel up in middle of hall with long lead( yes I know there would be some signal loss), I then played about with settings till I got what I thought was a good tone out in the hall.On returning steel to stage I heard someth...

You've come to the right place! Thank you, Bud! After browsing a few threads here and seeing the quality of dialogue, I was sure this is the right place. * * * * Someone posted a reply here with a couple of pictures of a (DIY?) tilt-back-able cab with an adjustable ports (if I recall correctly), an...

They are all good. Some are "better" than others. It's up to you to draw the sound out that you like to hear. :) You will probably have to just try different things out to see how it effects your playing & what you like. Thanks for replying! Suppose one cab sounded the way you like wh...

I'm interested in learning about what would be the "ideal" characteristics of a dedicated pedal steel guitar cab. For instance, in prerusing the archives, I see that some people prefer closed-back and some prefer open-back. Might an "ideal" cab combine the rich timbre and warmth ...

Hope ya'll don't mind me replying to an old topic. Two things control the radiation pattern of a speaker at a given freqency: The width of the source (usually the diameter of the cone itself), and the wavelength (the lower the frequency, the longer the wavelength). When the wavelengths are long rela...
