Elvis try the Eu1400, its solid and can go into lots of different enclosures!

Best value for Money I have come across under R1000!

Hello my beautiful Daughter

Yip, we don't need 100 million dB for everything!

Erik, not bad value - will share some acoustic data shortly also

Which hybrid?

@@The-Sound-Guy 18h800

@@DJJam68 that will be a highly controversial video, though for you guys I think I can line it up to Test

@The-Sound-Guy it would be highly appreciated. I would be extremely curious if hybrid products will also be one of the brands that don't meet the specs.

Yes The Hybrid 18H800 Would Be A Great Test For Us To Know Really if it is 800w continuous ​@@DJJam68

Hello my friend, sometimes the graph does not automatically updated - go to a new menu and back again changes the graph. The speaker is able to play to the drivers Fs or 30hz in a large enclosure, this is up to you and the design choice you make! Here because im used to tuning a certain way im quickly just reviewing the rough enclosure size, not designing for purpose to be subwoofer it's more of an overview. @Sco0or my advice is to always remember that any speaker ultimately will reach Xmax sooner in a large enclosure, when this happens distortion sets in very fast without a good high pass filter which will also "Cut out" some low frequencies. This means a balance must be found between a large box for deep bass extension or a smaller box for higher levels of output which is typically Half of "Vas" Value. Larger box will increase group delay, smaller box better group delay and better cone control.. my opinion -6dB@45Hz F3 in the smallest design possible is best for most 18"

@@The-Sound-Guy A smaller box makes a group delay smaller for very low frequencies, but at the same time increases a group delay for 30-50Hz which is more important than 20Hz. Besides, it's hard to get 50msecs for 20Hz (in most cases the delay is smaller for that frequency), but it's pretty difficult to limit a group delay below 8msecs for 40Hz. I'd rather agree to have 40msecs for 20Hz than 12msecs for 40Hz And HPF is a disaster for a group delay (( I'd rather spend yet more 200-500 eur for an additional driver, or to select a driver with higher SPL sacrificing something else, than to use a HPF. This is for a home hi-fi of course. PA uses different requirements. And thank you very much for the information.

Yes we do look at group delay, though I'm of the opinion unless it is for critical application group delay should be taken with a pinch of salt.

I highlight this in the full blog post here www.thesoundguy.co.za/blog/Loudness. Pa applications aside, for car and home audio if you just want a nice sounding system you really don't need much at all to have a good time!

Well spotted Erik, though it is important to note I had loaded the driver to show how Winisd might show an error & left it at that within the early part of the video. The B&C and the Fane 18XB are loaded with the brands calculated Xmax so in truth I still should smash on another 1mm onto that value of 12mm for the Lavoce Safe184.03.

@@The-Sound-Guy yes no plus that difference might not relate much to peak spl i mean 9mm to 12mm is not a giant amount of more excursion.

Jeff, hello good sir. We will be trying to cover all aspects of Diy, our goal for empowering our brothers & people of Africa!
