Thinking about building another pair of cabinets. Looking for the perfect driver/horn combo and thinking a 510 or 603m might be what im looking for.

Hahaha, you always have something Kevin. What else do you have? The DCM50 won’t fit in my cabinets with my current horns. What your opinion between the 50’s and bc85 drivers sonically to your ear?

Yes, toed in pointing at my nose. They sound very good.

I know nothing about those til now. How do they sound compared to the B&C stuff? I looked at the specs and 3 drivers with 2" dia and seems only spec that different is the weight and the price. All 500hz to 20,000k.

You are absolutely correct. I pulled the cabinets out from the back wall 2' and the sound stage has improved. The drum set is now moved to the rear wall as it should. Sounds more enjoyable for sure. They are still 9' apart and i moved back further away from the cabinets as well about 13-14'. Sounds great anywhere in between 10' to 14'. Thanks

Thanks for the linc.

Am I mistaken or did Crites used to sale the cabinets empty for about $600? I don't see them listed on the Crites site. I have been thinking about putting together another pair of cornscala using different components and vineer.

Just curious if anyone here has used both of these drivers. I would like to know your opinions in a 3way setup.

Another spec I found different between HL4750(ZXPC11x17.5) and the JBL M2380 is the length difference. The M2380 is 4.5” shorter than the HL4750. Would that create lower frequencies with the 4750, the longer horn or allow it to go lower?

Ok, I’m gonna just that spec on my horn. Do you know if anyone is making the mumps horn used in the new CW 4 or something close. I would really like the build another set using those horns.

Ok, thanks

Ok, I’m think I understand you now. A slotted horn has more air pressure or resistance causing more electrical resistance(ohm) in the driver?

I’m using your ALK universal. So would it be an issue to try a different mid horn with my current components?

I checked the specs on my BC DE85 and says 108db spl not 107db like I read somewhere else, so I’m at 101db on my mid giving me 5db above the woofer spl. That is very close to the same as TubesGlo . I like how I can hear everything in the recordings, very articulate, but missing something. In your face vocals and mid bass punch seems to be missing with this open horn. I also noticed in the BC specs that this driver goes down to 500hz, the cross over and horn are capable of 400hz. Do you think that could be an issue?

Ok, I’ll see if I can find one today. I really like the looks of your CS. Everything centered on the motorboard and the stain. Very nice. Mine started out as vertical CW home built. After 20 years I wanted something different. That’s why my components might look kind of odd with their placement. I’m now thinking seriously about trying a butt cheeks style mid horn just to see.

I agree.

Do you have any good pics of the M2380 horn?

OH yeah, A lot different. Thanks for the great pics. I may be trying a different horn in my CS. I really miss the in your face mids that the old 600 horns had.

Their both 90x40 elephant butt cheek design, but the M2380's are a 500hz horn. HM4750 is 400hz. Both look the same to me.

Ok, I just looked it up. Your Crites 1526 spec is 97db spl, so with 12db of attenuation your running the mid 1 dB above your 110db spl mid driver. The drivers are playing close to the same output. Maybe I should try that setting on mine just to see. Our mid horns are different and mine being open is very laid back, I actually think my mid could be bumped just a notch higher output. I’m now at 4db above my woofer output.I will have to try both ways again now that the speakers are in a much bigger room.

Ok, what is the spl of your woofer? Just curious to how many db your running the mid above the woofer. Our combos are a bit different, but I’m just curious to your final setting.

I bought my horns used from no.4, so the horn in his pics are mine. Just thought this horn thread could benefit anyone experimenting with horns in a Cornscala or whatever.

You may be correct, the HL4750 does look to have a short slot. Here's are interesting thread with pics i found.

The HM4750 has a slot, the HL4750 does not. The HM is still a 400hz horn.

Thanks Deang
