its possible, but theres many problems with it.

firstly, the drivers are bloomin expensive (only one i know is the PD124). these weight stupid amount on their own.

put these into a horn, and it will be the size of a full height wardrobe, at least 150kg of wood per unit alone!

then theres the 'advantages', altho its rumoured you will end up with fuller fatter tone, for the equivilent cab size and driver cost, you can easily have 2-3 18" versions having a larger louder output, better power handling and are easier to move (seperate cabs instead of one mass).

so id say, if your a rich c**t installing your private basement club out, then by all means make some to install, otherwise stick with single 18" horns!

cheers, Pat

The larger the Sd of the driver, the shorter you can make the horn path length for an equal cut-off. So it can extend pretty good on a band pass horn. Still it would be big because of the relative low compressionfactor (horn begins already big).

it's possible, but no point to it. if you went that route i hope it's a perma install and not something you will be move 3 times a week...
 
take the PD2450... huge and is in the TSW 124 i do believe that Mykey posted. i would still go for 4x 18's vs 2x 24's though...

LF H1024
 

Low frequency system - front loaded horn design – passive
Designed to extend the low frequency range of long throw mid-high frequency systems at high sound pressure levels.
Applications
The LF H1024 finds its application in systems for:
distributed sound reproduction: e.g. large clubs and dance halls
sound reinforcement: e.g. medium to large concerts, large musicals, operas and circuses

Description
The LF H1024 is the largest member of the horn loaded low frequency systems. The system is designed to extend the low frequency range of long throw mid-high frequency loudspeaker systems. Delta Loudspeakers SA is one of a few professional loudspeakers manufacturers that provides 24 inch low frequency systems.
This system is based on a 24 inch transducer with a 160 mm voice coil integrated in a sealed enclosure and coupled to bended horns. The horn design is inferred from a snail-shell. The mouth opening covering the complete front of the cabinet assures a low cut-off frequency. The enforced enclosure is manufactured with 24 and 48 mm Finnish birch plywood glued together in conjunction with dado joints to assure the highest quality of robustness. The black textured semi-matt paint makes the enclosure water repellent. The horn is protected by an aluminium grid with octagonal holes, designed for maximal strength and acoustical transparency. The removable foam attached to the grid protects the system from splash water and dust. Two Speakon® male connectors assure reliable electrical connections and the possibility to feed the signal through the system. Four large recessed steel bar handles and wheels mounted on the rear panel assure comfortable carriage. The system is optionally available for fix installations without wheels and handles.

Related and complementary products
Following complementary mid-high frequency loudspeaker systems are recommended for a well-balanced sound sensation:
mid-high frequency horn systems: MH H2010 and MH H1010 (long throw)
line arrays: LA 2005 and LA 2005SP (self-powered)
amplifier: AMP 2000 (bridged mode)

i thought the subject was 24's . Norty 'll smack your botty!
worth checking the beyma 21" out too, for horns. it does need treating though, to stiffen the paper, particularly on the 1st rib out from the centre.
