Thread-topic: [AUDITORY] loudspeakers for localization experiment

Dear Sathish,

we've used in the past coaxial speakers, where the tweeter is mounted in the middle of the woofer, such as the Equator D5 or the more classic Tannoy (there are several models now with this configuration, such as the 609 or the Gold 5). 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 100Hz). 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 hope this helps

Lorenzo

Dear list,

I’m looking for some advice. I’m searching for a loudspeaker specification for a free-field localization experiment.

I need single drive full range loudspeakers which will be placed in a circular pattern around the participant at 2 meters distance from the participant in the 15 x 15 feet experimental lab. The loudspeakers have flat frequency response and power consumption around 100 W or higher.

Any recommendations from members of the list will be helpful.

Thank you in advance.

Regards,

Sathish Kumar.
