Given the distance, listener to speaker, anything other then a single driver (coaxial would be my suggestion) would probably not be a good idea.I have no idea of your budget, but the Equator Audio D5 is a very fine near-field monitor class coaxial driver loudspeaker. I believe they are only sold in pairs and retail for $499 here in the USA.Good luck!- Neil WatermanOn Mar 7, 2017, at 5:26 PM, Chait, Maria <m.chait@xxxxxxxxx> wrote:Dear Colleagues,So far we have been conducting our behavioural experiments using high quality headphones, but for various reasons will need to shift to using free field sound presentation for some of our work. I was hoping you might be able to recommend a high quality loud speaker to use for this purpose; Ideally, one that we can purchase easily from the UK.Our requirements: Experiments are conducted in a small-ish sound-proof booth, and we plan to position a single loudspeaker about 50-70 cm in front of the listener (space constraints prevents this from being any further away). Stimuli are spectrally rich ‘soundscapes’.My understanding is that we should prefer single cone speakers?Many thanks,MariaMaria Chait PhDReader in Auditory Cognitive NeuroscienceUCL Ear Institute332 Gray's Inn RoadLondon WC1X 8EE
