hi all,

thanks bowtie - i was wondering if a one inch throat could
really meet the woofer somewhere below 1k.

but how high can the 515 be crossed over and still sound ok?

not aiming for true fullrange - just whatever can be sensibly
achieved with the drivers to hand - best use rather than
ultimate system.

also, is there a plain english explanation for the operation
of phase plugs - jbl radial, altec tangerine, tannoy pepperpot?

same job - different geometry - how does it work?

warm regards,

adam

btw - had my ear up to a tannoy 15" in a canterbury enclosure
very smooth tweeter - even from an inch or two away...
