Trelja...I couldn't have said it better. Bryhifi...I spent two grand on power tools, bought 3 or 4 20 foot sections of PVC water pipe, and built a pretty cool cylindrical 3-way using SEAS 5 mid and 0.75 plastic dome, with Peerless 8 down-firing woofer. I had built a similar cylindrical speaker as a kid using 3 foot clay sewer pipes, mounting a coaxial Jensen or Utah (remember them?) driver upward-firing into a plaster-filled kitchen funnel for 360 dispersion. What a hoot! So I decided to revisit that idea with modern materials. Well, no-one seemed excited about a cylindrical shape, so I never built the second side. Sound was pretty good, although woofer/mid crossover was problematic. Got good at voicing crossovers, and noticed that I could hear 1/3 dB changes over 1.5 octaves in the upper crossover region. After seeing that raw driver sensitivity tolerances are typically +/- 5-10 times that level I quickly realized that it would be impossible to make speaker systems consistently without customizing each crossover, or spending a fortune to get tight-tolerance drivers. I built with others 20 pair of a nice 6.5/1 two-way a few years back that ALMOST got into production as a reinforcement system for a digital piano mnaufacturer. A local high-end dealer liked them A LOT, but we couldn't get the cabinet maker to take a repeat order at a reasonable price. Voicing a matched-pair of speakers is a labor of love, and I have great appreciation for those who do it well. I preferred these two-ways to many commercial designs for a long time, but after I heard what Bruno Pelchat et al at Verity Audio accomplished with their Parsifal Encores, in my living room, my jaw dropped! Had to have 'em! So I'm done...for now. (PS. Want a good deal on Seas 5" 'bullet' dustcap, or those tweeters? How about the Peerless CC line 8"? A nice router...or maybe a belt-sander? Oh well, it was fun. It's all about the process, anyway, right?) Shabbado...you mean "low-pass", and no, that's NOT what you want to do. Room treatment, upstream components, maybe 1-2 ohms on the tweeter: try 'em all, and have fun!
Replacing my tweeters a good idea?
I have a pair of infinity Delta 70 loudspeakers. They have 2x8" 1 6" 1 4" and a metal tweeter. They image superbly, and set a good soundstage. People think infinity are bad, but they are great in my ears, apart from the metal dome tweeter. It gets a bit harsh on some recordings. Is it possible that i could replace the tweeters with something else, say dynaudio tweeters? would it be worht the trouble? I am not getting new speakers.. so dont bother trying to say that. :P thanks
