Open Baffle Epiphany!

Martin,
That is very helpful
Thanks!

Thanks for the link. It's over my head for sure but booked marked. Should probably start with an active. I don't have a high powered ss amp either.

 

[rogerfederer]

PG uses plate amps you can get from parts express. or one of the crown class D amps would work great. or something BPC from craigslist. you are only doing about 40-90hz through the woofers.

I'm shopping

Behringer cx2310 for $80. http://www.parts-express.com/behringer-cx2310-super-x-pro-crossover-2-way-3-way--248-664. Is this a start or should I step it up.http://www.parts-express.com/dbx-driverack-pa2-complete-loudspeaker-management-system--246-182 Or in between. http://www.parts-express.com/dbx-234s-stereo-2-3-way---mono-4-way-crossover--246-103

behringer has a mixed reputation amongst the pro audio crowd but i think PG has used one of those with good results

Can't comment on the Behringer crossovers, never heard one.

I have been using a dbx Driverack PA for over 10 years in a wide variety of speaker systems. It is easy to use and adjust, meets all my needs, and has been very transparent. It has never let me down.

There are plenty of reasonably priced active crossovers available that will work very well in OB designs.

I do have what I'd call a true "passive" sub on a porch system. It's a Marcato outdoor sub with a fixed crossover and it's powered from an old Marantz as are it's satellite speakers. The receptacle cord is for an outdoor fountain.

The Ashly and Behringer are a better match with ss amps than with my SET amp.

Two things I like about this active crossover is it's simplicity and size. With the pro units you've got an overwhelming array of controls and if you accidentally change something then you've got to spend time trying to figure out what's different. Pro gear is meant to fit into pro racks so you've got to account for their wider width with ears which aren't always removable.

The Rolls is smaller with a wall wart and pro audio 1/4" TS connections.

There's also a stereo version so you would only need one.

It's only a 12 dB/octave rolloff though as opposed to the 24 dB's of the sx21

 

[mkane]

Got that. something I neglected to see, the 1/4 inputs. Do you think 12dB/octave is ok? I have an issue buying Asian

 

[MJKing]

Do you think 12dB/octave is ok?

Yes, I have never used anything steeper than a 12 dB/octave crossover in my OB designs.

 

[mkane]

Thanks. Wondering if these will kick the Cornwalls upstairs doing FM duty! Going with the Eminence Alpha and still undecided on the full rangers. I did see a build that makes if easy to sway out full rangers which may float my boat.

 

[mkane]

Driving me nut's. Seems like theres a zillion different design and wondering if placement on the baffle matters. Full ranger at ear level? rooms 16x26

 

[mkane]

OK. I have chosen 10" full range speakers to pair with the 15's.

 

[mkane]

And it's done! AN Classic 10's Ferrite.

David Dicks usually recommends his 8" Classic.
