If you had stereo subwoofers which reached up to 120hz that will minimise the horn size of the 120hz+ unit

A horn is another new sound compared to yuck bandpass,Ive never bothered building one,I know their bad. Instead I have a jbl 15" on overdamped bass reflex in my lounge Smile

I didn't say bandpass, but bandpas horn. Here is a drawing: http://www.speakerstore.nl/constructions/pbaudio/bandpasshoo rn_18/bandpass_18_1.gif Mine is modifed for 15" drivers.

The same as the F1, turbo and mach ballister subs. It isnt a horn, it isnt a bandpass, just a realy good mix of both witch sounds great! The only thing i'm worried about is the higher part of the band with, say about 250-350 Hz.
A straight horn will always preform better in my opinion. Maybe im going to test this in the comming year.

Hi Michiel,
How are you? That bandpass horn you have in speakerstore I am building right now with PD1850 what was the useable frequency response from your driver that you originally used? Also with the PD1850 what would be the HPF set at? What is the predicted response with the PD1850? I modified the cabinet a little using two horns in one cab and a support in the first bend and using 18mm Baltic Birch like what Bernie Sauderland did. Thanks!

How does that horn model up with a Peavey Low Rider 15?

Almost ready. Smile Next weekend i'n planning to do the first tests.

For pics see: http://michiel-rijckaert.fotopic.net/c379291_1.html

What are the T/S of the peavy? I dont know if a 15" will go well in this horn since I designed the horn  for the LAB 12.
But, maybe it will work.
