The owner of Stereo Integrity, Nick Lemons, will be giving us an insight on his efforts to redesign and improve upon the ever popular Mag subwoofer.
The whole concept of the new Stereo Integrity Mag is to take it to the next level in every aspect. Number one issue at hand, to make it sound better. Quite a feat considering the current generation Mag is very highly regarded in car audio. The inductance will be cut in half which broadens the bandwidth a HUGE amount and will make the subwoofer sound more natural. A shorting ring will also be implemented on the pole piece without using a sleeve or cap, which will also help with inductance rise and fluctuation.
Finding the perfect cone is also a top priority, as it can affect the sound in a bad way. Subwoofers operate below 80 Hz, but if you have a cone that has an 8 dB spike at 300 Hz due to cone breakup the lower harmonics of the spike are going to trickle down into the sound of the subwoofer even with 18/24 dB/octave slopes. A paper composite cone that is well damped and light weight is looking like a go for use on the new Mag, which means no extra distortion as a result of poor cone construction.
The new Mag will also make people with weight or depth concerns very happy, as the mounting depth is going to be below five and a half inches for the 12" model. Yes, that’s right – 5.5"…a shallow Mag. This is possible through the use of a basket with a fully enclosed motor. Weight is also going to be shaved off landing the new drivers in the 20-25 lb category. And of course the Mag will still use a 3" diameter vc former and be able to handle 1000 watts continuous. The new Mag will keep its SPL abilities and embrace new and improved SQ characteristics… all while working in smaller enclosures. Enclosure sizes for the 12" are 0.8 to 1.1 cubes sealed and 1.8 cubes ported to 33 Hz.
