Hi
Ive got Ev T18 bass cabs loaded with PD186's, ive never had any problems what so ever and think hey sound the business, Ive heard quite a few people say over the years that the EV EVX-180B would out perform the PD186 in this cab, would any of you guys agree with this? what you think as i am baffled- i have copied the spec sheets for both drivers below-take into account the Ev costs-Ł605 new and the PD 186-Ł180ish
Thanks
PRECISION DEVICES 186
|
Heavy duty 18" cast aluminium frame with extra wide flange for increased rigidity |
|
|
700WRMS |
|
|
5” copper voice coil capable of dissipating tremendous heat build up when driven in concert conditions |
|
|
110 oz. magnet |
|
|
Huge copper area and breathing arrangement of the voice coil ensures superior power compression performance |
|
|
Double suspension maintains pure piston action for the moving mass even when driven with the most complex programme input signals and provides additional durability against the rigours of life on the road |

Description: |
|
Designed to provide superlative high power bass and sub bass, suitable for all systems demanding the best possible low frequency response. A popular choice for horn loaded subwoofers when the PD.186’s full low end can deliver extremely high SPLs.
Ideal for three-way direct radiating systems where the powerful bass comes into its own. Well suited to use with PD.107/PD.121 and PD.C2/PD.C14 to produce direct radiating/horn loaded systems where the double suspension system allows it to thrive in the demanding touring sector. |
