Cabrini Redux

Re: Cabrini Redux

I ordered the drivers and resistors last night. I will be wrapping my own coil for this build I will be building a Tower to fulfill a certain WAF factor. Do I need to worry about over excursion?

In post one he talks about building a tower. Build these into a tower with the tweeter about 33" off the ground, and you will probably be very, very satisfied with them.

I may try a pair of these.

Re: Cabrini Redux

Interesting...

All the talk about tower this and that, made me look into modeling a 30L vented, and came up with some surprising results.

First, the graph. F3/6/10 of 40/37/35.



Excursion at 30 watts



If a guy can live with the hump centered around 90 Hz (and it isn't toooo objectionable) and the inability of the system to play super-loud, I think venting could end up working really well.

Below tuning, there is plenty of cone control - most vented systems will pop out at just a watt or two below tuning.

Interesting. Port it up, Ken.

Re: Cabrini Redux

Cool build and design philosophy you have there.

Re: Cabrini Redux

Line the enclosure with a bit of mattress topper and that hump should even out as well. These grs drivers are looking like fun to play with!

Re: Cabrini Redux

Lowell Simpson will be picking them up on Monday to give his impressions, and Nick will hopefully be stopping by this weekend for a listen as well.

Lowell is willing to get these into the wild along his route, within reason of course. Hit me up if you want them for awhile, and I can check with Lowell or whomever has them at the moment to see if it is feasible.

I believe Chuck has second dibs at the moment.

Re: Cabrini Redux

Nick had them most of the weekend, and Lowell just picked them up this afternoon. Hopefully they both have good things to say about them!

Re: Cabrini Redux

I wont get a chance to listen to them until Thursday. Maybe next week will get me near Laporte. I will let Chuck know if so.

Re: Cabrini Redux

We will get it figured out Lowell.

Re: Cabrini Redux

I have nothing bad to say about this build . Listened to music and a movie on these with a sub in stereo mode and thought these sounded great! I noticed when listening to some 70's rock that , in some tracks the low end was a little more pronounced ( sub disconnected ) Im guessing this is due to the production/mixing of the content? Everything sounded neutral to my ears and nothing stood out or killed my ears for the couple days I had these in my grubby mitts. I think I read a post where someone might build a tower version , this could be another neat build too and think they would be worthy of a try. All in all , hell yeah we enjoyed these very much . Curious what others think. As always , nice clean build Johnny ! Kudos and thank you for the offer to listen to these in house.

I was listening to these off axis at home, but listened to them at JR's place, mostly on axis and both locations were pleasing to our ears

Re: Cabrini Redux

Thank you for the kind words, Nick - the slight bloat on the bottom end was probably due to the 1.0 Q design emphasizing the 70-90Hz region.

Re: Cabrini Redux

I have all the parts and hope to be able to build a tower soon. JR gave me a few pointers on the tower design and looks to be a very nice build.

Re: Cabrini Redux

Seriously. If you want to play Lorde, Royals, you'll need a sub. If you want to listen to music, these are pretty nice. They are afterall sealed speakers. They do vocals really well. Johns integration between drivers is really well done. I Recently bought 'Linda Ronstadt Duets' and the first few songs have strings, ya know, cello, violin, and they sound really nice with her deep voice as well as her partner.
I don't remember what tweeter that is, but I think I like it.
I will get these to Chuck this week.
Thanks John.

Re: Cabrini Redux

Just thought I would give an update for anyone wishing to build these using all PE parts. The buyout coil (269-303) will work with a quick un-wind procedure. These are not glued coils, so when removing the tape - keep your fingers wrapped around everything or it will go BOING all over your desk and cause a few cursewords to happen. Have some tape handy to wrap it right away, as well. You can't say you haven't been warned ;)

I measured two of them at 2.37mH, and removed 43" from both to get to 2.2mH, at 0.86ohm DCR. These will work very well for this speaker.

A little personal experience?
