I have two pairs of Dayton 5 inch full range drivers. I am planning a truncated pyramid shape for a 0.25 cft ported cabinet for one pair. I would like to build a small bookshelf sized horn design for the other pair but do not have a proper design. Most of the designs on the net are tall floorstanders. Where can I get smaller designs? This is for a bedroom and low volume listening and bass not very important. Thanks.

Follow Ups:
Horns are not as volumetrically efficient as ported boxes, unless the box is large enough to use the room corner as part of the horn.
IF you had space and wanted something pretty powerful, then this dual PA130 XKi alignment K-coupler would fit the bill. I have a single PA130 in a little XKi and it does well. 12mm Baltic birch would be a good thickness for the aperture plate for the single model - mine are 9mm BB and too resonant for my taste. I think this dual 5 would be impressive for its size. Details are at Diyaudio's XKi thread.

Thanks a lot for the information. I have a lot of studying to do. But enjoying it.
Best Wishes

The box designed by gychang on page 8 of the XKi thread you referred to work for the GR Research LGK 3" full range driver? That box was designed for the Fountek FE83. It looks small and interesting. Here's a link to the specs. Thanks. Hope you're doing okay.
In think your best bet is to join into that thread and ask specifically the "right" XKi alignment from Diyaudio memeber xrk971 - -he's extremely generous with his spare time and will run the simple Akabak scrip for you.
You can make it easier for him by posting the needed parameters in the form as follows with this Pyle speaker
Def_Driver 'Pyle PYM1298' |Notes: Pyle Eminence 12" driver 97.8dB 1W/1M 3.2mm XMax 600 watts
SD=509.9cm2
fs=44.2Hz
Mms=43.1
QMs=6.76
Qes=0.31
Re=5.16
BL=14.15Tm
Le=0.54mH
Vas=111.2L
don't go real thin in the aperture plate as it can resonate

Combining "horn" and "small" in the same sentence is pretty only another way of saying "just a tweeter". You can't miniaturize wavelengths.
