Dear Maria,
we have recently purchased a number of Equator Audio D5 speakers, which are are based on a "coaxial" design, i.e. the tweeter (high frequency driver) is mounted in the middle of the woofer (low frequencies).
This particular design allows for a generally wider field of listening, and for the speaker to be put closer to the listener without creating issues related with the low and high drivers being not in the same position. The advantage of this design if compared with single cone speakers ("full range speaker") is that it allows a much wider frequency range, it requires much less space to sound well (full range speakers tend to require larger rooms to have good low-frequency performances), and it does not need complex/large resonators, wave-guides and horns in order to extend its frequency response.
Tannoy is famous for its "Dual Concentric" coaxial design, and some of its models (e.g. Tannoy System 600) have been used in the past for psychoacoustics experiments. But it's more difficult now to find these speakers, and the new models are mainy
for HiFi and often passive (e.g. they require an external amplifier).
The Equator D5 work very well, so I'd definitely recommend those. You are welcome to come to listen to them in South Kensington, if you come close to there sometimes!

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, Maria Maria Chait PhD Reader in Auditory Cognitive Neuroscience Lab site: http://www.ucl.ac.uk/ear/research/chaitlab/ UCL Ear Institute 332 Gray's Inn Road London WC1X 8EE |
