I started with a vintage Heresy pair, then Chorus IIs, and now vintage La Scalas. Learning is fun. I’m definitely in this journey for the learning experience , and achieving what I want for personal use w my current means. not for klipsch purity Quote Link to comment Share on other sites More sharing options...

If you do build your own cabinets with the parts you have I'd recommend looking at @ClaudeJ1 Super Heresy's You should stop bumping this thread and instead link it with a PM - for obvious reasons.

triceratops Posted January 12 Share Posted January 12 Congrats on your score, 1000frogs. I sent you a pm. Quote Link to comment Share on other sites More sharing options...
JohnA Posted January 13 Share Posted January 13 On 1/11/2024 at 5:42 PM, Deang said: If your plan is to gut them, the cabinets would be practically worthless. I can’t imagine anyone paying for them with no drivers or crossovers. if you are tight with money, the answer is definitely not destroying a perfectly good set of loudspeakers. They were designed to be used as stage monitors and have a strong vocal presence. Converting the networks to the AA will rebalance the loudspeakers. It will pull the midrange back so you can hear the bass. OP, don't modify them until you get them working and you listen to them for a while. Actually the Type HIE is a Type AA with the woofer cap changed to raise the Woofer to squawker crossover point for the K-700 horn. https://products.electrovoice.com/binary/EVM-12L Series II EDS.pdf From the graph in this spec sheet, you can see the woofer has a rising curve and hits about 102 dB/w/m around 3k Hz. Klipsch voiced this speaker for outdoor use (and there it sounds great). The squawker and tweeter are run at 104 dB/w/m. A hybrid crossover more like the Type E will voice it more like a home Heresy and make it better for indoors. However, that rising woofer response curve may need a steeper low pass filter. This is a DeanG job. I had a similar pair of HIPs (same crossover and components). They were ported and still pretty bright. @ClaudeJ1 may be able to help you design a port to extend the low bass limit to home audio limits. He likes that woofer for that. He has developed a mod for the Heresy cabinets with that woofer and a port and a corner that you might like. Otherwise, that woofer is popular with guitarists and not suitable for a home edition Heresy. 2 1 Quote Link to comment Share on other sites More sharing options...

Thanks for all of this info, it’s always been my intention to sit with them working for a bit before doing any work. I have managed to fix them and have been listening to them. It does seem that they are not voiced for indoor home use but I will wait longer so do more research Edited January 14 by 1000frogs Typo - I have finished, not haven’t Quote Link to comment Share on other sites More sharing options...

It's a very nice and balanced sound. It sounds just like turning the gain up three steps or so on an analog mixer. 1 Quote Link to comment Share on other sites More sharing options...

And if you have any extra, you can use it to Jump Start a Diesel Locomotive! bs alerts notwithstanding. 1 1 Quote Link to comment Share on other sites More sharing options...

Yes, I do understand. It's quite normal to decry thicker cables giving a little more current and sonic improvement to a speaker. It's also quite normal for the DIY crowd to find out that it's quite true, and definitely worth the time to try it. Quote Link to comment Share on other sites More sharing options...
Deang Posted January 15 Share Posted January 15 Go big or go home. The rest of us have gone to 6AWG. We solder it to the VC wire. 4 Quote Link to comment Share on other sites More sharing options...

PWK told me it was a waste of good copper just to drive a #30 gauge wire in the K33 WOOFER. So only worth the time to YOU, as my bs meter is pegging about doing that to a frikkin' Tweter!
