results of playing around
Thanks for all the comments. As you,ve probably realised I,m not a purist and my kit is fairly modest. I was originally going to use the 4" driver ,tweeter and crossover from a pair of Mordaunt short MS10 's because they fitted the holes in the Vega cabs to supplement the 12" McKenzies. I found a pair of 7" mid, crossover and tweeter, new but unused dating from '88, 8 ohm, 40w made by Hi.co which I can't find any info on but don't imagine they're anything special from the connections on the speaker terminal.Rather than cut the cabs at this point I made a couple of spacers to bring the mids forward by 50mm so the rear fitted into the 4" tube . I bi-amped them to the denon avr 2307 and I have to admit the difference is astonishing, much better than I expected. The thumping bass is much more subtle now. I think the amp feeding the McKenzies is default at 80 hz but can be altered , haven't tried doing that yet. The amp is on pure direct sound setting. I played a Hifi sound stereo test record (1974) to check the phasing and also the turntable setup, all good. Then used a Tag McLaren test cd with very detailed recordings and again it sounded lovely, so I'm very pleased. I think my Linn Helix speakers have slightly more detail but the vegas have a little more warmth. I,ve seen various comments saying Bi-amping doesn't really make a difference but from my playing around seems to me it does, or maybe it's just placement of the speakers, which I do realise is much more important. It's been fun and stupidly cheap, about £50 in all.
