LOUDeQ - Variable "LOUDNESS" Passive Equalizer Network with Diatone 4" full rangespeakers and 1" ports This is a great kit for a computer speaker, near-field monitor, DIY boombox, Bluetooth speaker etc. All you need to to is add the enclosure and amplifier. Enclosure should be around 0.1 - 0.25 cubic feet Kit comes with: 2 - Diatone 4" full range speakers 2 - 1" flared port tubes 2 - LOUDeQ filters DIATONE 4" FULL RANGE SPEAKERS Great full range sound and high efficiency from attractive 4" speakers. Made by Mitsubishi Japan, Diatone is known for some very top notch mini and full range speakers. We made a special buy on these and can bring you this superb sounding little gem at a great price. Dust cap is directly attached to the coil former for beautiful extended top end response. Poly graphite cone is rigid yet lightweight and the cloth surround will last forever 1" vented coil handles plenty of power to achieve considerable output levels. We were very impressed with these little guys, they compare vary favorably to the FaitalPro 4fe32. You won't be disappointed Power Handling: 50 WATTS RMS Useable frequency range: 60 – 18,000 HZ. IMPEDANCE 8 OHM SPL: 89dB Voice Coil Diameter: 1 In Depth: 2.750 In Cutout Diameter: 3.75" (recess) 4" flush Bolt Circle Diameter: 4.5" 1" FLARED PORT TUBE 1" diameter flared port minimizes port turbulence for cleaner noise free extended low frequency output, - 4" long, EZ press-fit in 1-3/8" opening - overall diameter 1-5/8" LOUDeQ Full-range speaker dynamic equalizer The LOUDeQ is a unique passive filter network designed to function as a variable "loudness" circuit. LOUDeQ will help flatten response of compact full-range speakers systems and provide gradual excursion limiting at higher input levels. -integrated spring loaded terminal plate - See the response chart. The red curve is the response with low level input and provides a low Q notch equalization centered at 2Khz of approx 3dB. This is great to adjust for the limitations of human hearing at low levels and will provide a warmer tone and add a bit more air to the top end - As displayed by the blue curve, the low frequency will gradually be reduced by a maximum of 2.5dB as input power increases to around 40 watts. This cut flattens the curve and limits LF driver excursion. Midrange will also increase approx 1dB with slow rise to 20Khz to make up for a bit of driver rolloff. The end result is increased maximum SPL for those times when you want to crank your mini speaker project
