Epic Custom Built 2.4M Long Quarter Folded Horn Subwoofer

Reluctantly looking to move on big bertha as we like our new neighbours and this thing isn’t suited for high density housing, it’s more suited to a dedicated home theatre room on a large block and/or a nightclub.

Custom designed by Paul @ RedSpade Audio with a no holds barred design brief (https://redspade-audio.blogspot.com/2014/12/hts-215.html). I remember Paul’s comment when he sat down for a listening session after tuning the DSP was “I may have gone a bit overboard!”

Key stats:

2400 long, 600 high, 500 deep. That’s 2 point 4 metres long in case you think there was a typo.
Dual 15” Dayton RSS390HO-4 15" Reference HO Subwoofer
Fed by a Dayton SPA-1000 class AB plate amp
Quarter folded horn layout, so effective sound path is ~4.8 metres long

To want this subwoofer then you are looking for something ‘a bit overboard’ and the answer is a 2.4 metre long dual 15” horn subwoofer. I know this sub is what a number of people will be itching to have but put off by the effort to do so.

Looks wise. It has had a basic black spray paint that then we glued a silicone shelf liner on top and the ‘front’ side to make it look quite reasonable behind the couch and you could similarly put it against a rear theatre wall. There is a speaker grille piece with loose speaker cloth on it that you could contact spray and use, I just left it hanging loose as was out of sight and out of mind. So it’s utilitarian but serviceable in terms of looks.

Performance wise it’s everything you’d think from 18hz. The glass downlight covers in the bathroom were attached with magnets, they dropped to the floor and broke the first time I gave the sub the full juice playing the Time track from the Inception movie. You will want a mini DSP or equivalent to get it flat and I'll throw one in if you don't ask too many silly questions like 'can you deliver it'.

Pricing wise I’m looking for 3k, effectively the replacement cost without the effort, design or delay if you were to build one yourself. The 1000w amp is ~$1100 on nb, the drivers are AUD700 each on wagners and USD600 on parts express with DHL before duties, the cabinet was about 500 before the effort of assembly. I can use the parts in my next project but I figure it’d be a waste for it not to go as is to a good home and cause structural damage and a lot of pleasure somewhere else.
