Product Details

Tymphany NE225W-08 8" Subwoofer Speaker

Tymphany's NE Series subwoofers feature an open cast aluminum basket design that minimizes internal acoustic reflections and helps cool the neodymium motor. An additional heat sink provides extra thermal dissipation. The cone is constructed of a coated natural wood fiber, with a butyl rubber surround designed by finite element analysis for linearity of performance. FEA techniques also contribute to the motor's copper cap, which reduces inductance.

Tymphany NE225W-08 8" Subwoofer Speaker
Tymphany NE225W-08 8" Subwoofer Speaker is rated 4.0 out of 5 by 1.
Rated 4 out of 5 by from Great WooferI'm writing this having used the 4 Ohm version which is no longer available.This woofer was chosen for a two-way build due to the overall parameters that fit the enclosure size we had in mind. Most outstanding up front was the incredibly low inductance, which tells of the well endowed copper capped motor assembly. Measured distortion levels at high output levels testify to the linearized motor. From 100Hz on up at 10W input, I am measuring amplifier like levels of distortion, between .1% and .5%. Below 100Hz, my noise floor just doesn't permit accuracy. The posted response plots were almost identical to what we found.This application uses the woofer to a crossover point of 1KHz, with a waveguide loaded RS28 above that. As a mid-woofer, this "subwoofer" is fantastic, producing liquid mids, with great vocal reproduction, all while literally shaking the walls when loaded into 1.2 cubic foot cabinets tuned to 33Hz. 150-250W amp would be the ideal match for this 8 Ohm woofer in this application, allowing it to reach its peak levels without the amps doing the same.As a sub, well, you might reach into the upper 20s in-room, and you do get some floor shaking. But for movies and such, they just don't reach low enough and will be easily bottomed out during effects. Be careful.I'm dinging them 1 star because we did see some quality issues with a few of the units, but PE, awesome as ever, came through and took care of the issue.Bottom line, these are incredible performing woofers.

Will this sub work in Free Air?

I am looking for a 8" 8 ohms sub to replace my car's sub. It is 04 LS430 with ML.
Asked by: SidneyFox
I would not recommend this woofer for free air use. Our best sellers for this exact model will be the Goldwood below.
