Welcome to the Nightfire Box Plans Homepage!

Due to increasing interest from home constructors in our new driver ranges we have launched this box plans page. You will find designs for you to use to make the most out of our world leading drive units, ranging from compact HIFI and installation loudspeakers, high-end transmission line studio monitors, high power PA full range boxes to scoop and front loaded horn designs that will take your sub-bass system that one step further.

We will be adding more plans to the page all the time so add this page to your favorites and check it regularly. And, send us an email to subscribe to our home builders email list to keep informed as new plans are launched.

All designs are available in kit form with optional hardware packs to cover all the extras you may need. Standard kits for 2-way and 3-way designs include the drivers and crossovers for a pair of speakers; For bass cabinets, the kit consists of a pair of drivers.

If you are interested obtaining plans that haven't been posted yet, send me and email and I'll happily prioritise getting those plans finished first. The loudest rear loaded horn is now posted which initial testing suggests is 2dB up on any scoop we've ever heard. Also, by popular demand you will see a range of 15" and 18" bass reflex high power sub designs below.

HIGH POWER PROFESSIONAL BASS REFLEX AND HORNS

Kit Code
Description

Sizes (mm)

15" COMPACT HIGH POWER BASS REFLEX - The most requested design - a simple to construct compact 15" bass cabinet for the PR15125, the high power sub driver. Massive SPL down to 40Hz, and a one person lift make this the bass cabinet of choice for touring bands/djs. Very effective in multiples. 850W AES, 1700W Continuous, but between 600W-1kW per box is highly recommended (@ 8 ohms).

H=500

W=600

D=550

2x15" COMPACT HIGH POWER BASS REFLEX - Double version of the NF-PRO15B, for installations or touring bands / djs who regularly play large rooms and want to make an impact. The coupling of the drivers extend the bass response and give you even more punch. 1700W AES 3400W continuous per cab.

H=928

W=600

D=550

18" COMPACT HIGH POWER BASS REFLEX - The big brother of the PRO18B, similar in design but with the extra surface area of an 18" to make your trousers move. With a response down to below 40Hz and relatively compact dimensions, this cabinet is suitable for all mobile and installed applications. You have two driver choices - the PR18125 is the 'high end' option, and the NGX18 gives you great sound on a budget and will make the most of smaller amplifiers.

1000W AES, 2000W Cont

20" Scoop / Rear Loaded Horn - Are your 18" scoops not loud enough? The PR20120 in this relatively easy to build scoop design will BLOW YOU AWAY! 500W AES, 1000W Continuous, very low power compression and unbelievable sensitivity gives you MORE BASS from a cabinet no bigger than a 'standard' 18" scoop. The 20120 really is a unique bass driver due to the way it behaves under power, giving you a 'truer' sub bass response, and insane SPLs! You won't be dissapointed...
