Firstly the BD312 Summary

The Delta 312 - 1000w RMS passive has three 12" BishopSound drivers sitting one on top of the other, but with the lowest of the three is a subwoofer being fed via a 3 Way crossover so that it handles bass frequencies, leaving the upper two 12" drivers to handle full range duties.

The High Frequencies are fed with our BRC175 Titanium Compression Driver.

Customers across the UK tell us these speakers reproduce sound close to that of a studio monitor which means your audience hears you're live or Pre-recorded sound to perfection!

Made from 100% 15mm Birch Marine 13-Ply Plywood for exceptional strength and audio reproduction the clarity of these speakers never ceases to amaze audiences and is easy to carry and transport.

This arrangement means that the BD312 has very impressive bass properties in its own right, although if you need ultra bass for big venues you can get a fantastic set-up by pairing a 312 with our 15", 18" or 21" subs. But what is really different about the Delta 312 is what it does to the mid-range and the amazing effect this can have for both live bands and DJs. Fast to set up, simply Plug and Play.

Important information about subwoofers

Subwoofers are designed to reproduce low bass audio signals between 30Hz and 150Hz. Driving them with full frequencies will cause permanent damage, so they should only be operated with a passive low-pass filter, a crossover network, or an active electronic crossover or speaker management system.
