Greetings,I purchased my first set of altecs a couple months ago on e-bay,when i tryed them out with an old el-84 scott amp,I LOVED the wide soundstage they sent out.After they were moved to a new location they were hooked up to a 300b integrated single-end 9-watt stereo amp,and am trying to get the best sound out of them in that mode,the frequency knob controls dont seem to adjust much,and sound like they need a cleaning.On another web site a guy said he upgraded his crossover with auricaps and mills resistors,saying this made them sound better.I added a set of binding posts to the cabinets,to utilize better speaker wire [straight-wire pro-12s added some needed low end]but want to still improve the mids and highs.The 14s may be happier with more power,those of you who have run them know,these are neat speakers and it would be nice to get them singing at their best.Any tips,advice,or past experience with the model-14s would be welcome.
