Back loaded horn design (help please)

[Puggie]

Ok this is not strictly full range but I want advice designing a back loaded horn and the generally used for full range designs so I guess the most relavent advice will come from this section.

I've been playing with hornresp but I would really like a bit of guidance as to what parameters affect what.

I have a pair of Volt BM251.4 midbass drivers www.voltloudspeakers.co.uk doing nothing, so I plan on trying to build a BLH cabinet to try and make them into something resembling a serious party speaker/good PA cab, my inspiration came for Cyburg's 'the viech'

I'll add a horn tweet later for the top end.

so how do I go about designing a decent BLH? what should I be doing, I want the smallest cab possible to hit 45-50Hz

First stop: read Martin King's site. Everything you'll ever need. www.quarter-wave.com That will help you with understanding the theory, and to narrow down your criteria and establish exactly what you want to achieve. With the greatest respect to hornresp's programmers, I think you'll find this a whole lot easier to use, and more useful in learning terms too.

This driver could fit in a nice scoop type of cabinet. You will never hit 45Hz, but a good 80Hz BLH punch is better than a BR 40Hz.

The cabinet will be very large (by domestic standards). There is no such thing as a compact BLH especially for a 10 in. driver.

You can visit SpeakerPlans.com for inspiration as well as other DJ oriented sites.

Thanks for the input, it now looks like they will be used for some high quality PA speakers, I need to hit 60Hz so I'll have a look on speakerplans.com and see what designs grab my interest and how big it will have to be.
