Hi, I am new here and struggling a bit. I would like to build a pair of speakers to replace my 30 year old 15 inch 4-way party speakers. I am trying to find an existing design that uses a 15 inch woofer and preferably a horn loaded upper. These are for 2 channel audio. I am looking for dynamics, high efficiency, a live sound. I listen to rock, pop, and country. I have a size restriction of 19" wide, 29" tall and 21" deep, due to having to fit them into existing cabinetry. Any help would be appreciated, thanks.
Greets!
There's dozens around the net that can be adapted to fit, so just depends on how much low end response you're willing to trade for mid bass eff. and how 'deep are your pockets'?

A Peavey SP2-XT can be adjusted to the same volume (Fs). They come 21" wide, 31.5" tall, 19 deep. If you cut width and height, and increase depth, you can achieve nearly same volume. 1508-KADT woofer, RX22 1.4" CD on Peavey horn. You can usually buy the horns on ebay used, since bands usually blow woofers. 1200 hz crossover, 12 db/octave. See spec sheet from Peavey.
Thanks...when I said existing design, I was referring to diy designs. Such as calpamos, (which I understand is discontinued). Just something that people have already been building and has acrossoved that is worked out. Thanks.
The files are still available. Corssover and cabinet drawings included.
The components are also still available so can be built easily.

In most rooms, these will easily extend to 40Hz...

Keeping the woofers sensitivity in the 97db range ( iow > high-efficiency along with a smallish box ), means a 15" Pro woofer of some sort.
- One will need to rely on a bit of EQ or LF Room-Gain to get a real 40hz response.
So, using 17"x27"x19" ( divided by 1728 ) one gets @ 5 cu' of box volume to play with.
I think the 4Pi box is around 5 cu' ( or maybe a smidge smaller ).
The JBL 2226H woofer model is mentioned as an option for the 4Pi and is an all-round great performer ( these come up for sale once in a while in the used market ).
