Horn tweeter swap?

[Carverpro 672]

I have a set of Cerwin vega pa speakers. They have a 15" woofer and a 4x4 compression cv-h25 horn tweeter....8 ohms.  Now these will not play as deep as my Cv home speakers as I believe they are tuned to about 45 hz. 

...But as far as loud vocals go..they are   louder than my Cv home speakers. The horn tweeters will rip your head off running off the pm1.5a. Just curious if these horn tweeters would improve the sound in my at-15's that currently have the stock dome tweeters installed.

Yes sir. That will be next weekends little project. I have built car subwoofer enclosures and have actually built a nice set of " audiophile " speakers in the past out of 3/4 " MDF using silver flute woofers, vifa tweeters and custom built solen crossovers. These sounded extraordinary on my Nad amp at the time.

...But this pm1.5a / cerwin Vegas is bringing out the bad in me. I have an itch to build something for extremely loud playback without subwoofers.  Either 2 15" or 1-18" with horns. But first I'm going to mess around with these cerwin Vegas a bit. Keep the woofers but swap out the tweeters and midrange. Bass is great. I want to see if I can make the vocals scream even louder.

I like the soft dome tweeter over the bullet horn.

Going to be cutting in to the cerwin Vegas this week. Scrapping the horn tweeters for now.  It's going to be my Vega hybred. Using At-15 cabinets, at-15 crossovers, se-380 woofers, se-380 mids and At-15 tweeters.

...Should work out well. All drivers have identical impedance ratings between the 2 sets of speakers. Right now the se-380 woofers are pounding harder in the At-15 cabinets. The Se-380 mids are 6.5 "  compared to the flimsy 5" ones in the At-15's.  The bigger ones are sonically superior and built a lot better.  The at-15's tweets sound better than the 380's.

It will be the best of both models merged into 1. Time to design.

I don’t think I’ve ever seen ‘flimsy’ and ‘AT-15’ I the same sentence.  Ever.

I’m not a big fan of deep horns.  At all.  Soft domes for accuracy.  Hard domes for dB if needed.  

But cool.  Good luck man.

The at-15's mids look " flimsy " and cheap compared to the mids out of the se-380's. The 380's are huge  and use better cones. Already have all the drivers out and built some custom baffles out of 3/4 mdf.?

Sounds like an exciting adventure and I am anxiously waiting on your next posts and updates.  Some pictures and video would be great.  Keep on experimenting.

Yeah thanks...you can follow the journey on the " Cerwin vega Frankenstein" thread. Should be up and running by the weekend.

Other than the floor space they take up, 2 - 4 ohm CV's wired in series is an option.

400-500 watts going into these Vegas is working out pretty good. Good bottom end. When I had the woofers out I was checking them out closely. No voice coil problem. Guaranteed this is the hardest these 29 year old woofers have been worked.

...playing the At15's..then the 380's ...vocals are definately sounding better with the bigger 380 midranges. Once I get them installed in the At15's cabinets...should be content.

My sick twisted mind has already been thinking about building a set with 18's. I'm waiting awhile until I see if the neighbors dont give me too much grief over my latest antics?
