We are currently creating a new setup using custom cabinets with= full-range drivers such as the Peerless 830987, which are reasonably flat = in frequency response (depending also on the cabinet design you chose) and = go down to 50-60Hz on paper (in reality you won't really have much below 10= 0Hz). If you are located in the UK and are interested in custom cabinets I = suggest you contact https://www.wilmslowaudio.co.uk - maybe they also ship = overseas.

I=92m searching for a loudspeaker specificat= ion for a free-field localization experiment. I need single drive full range loudspeakers which will be placed in a circu= lar pattern around the participant at 2 meters distance from the participan= t in the 15 x 15 feet experimental lab. The loudspeakers have flat frequenc= y response and power consumption around 100 W or higher. Any recommendations from members of the list will be helpful. Thank you in advance.
