Is it possible to horn load a coaxial driver? for example a straight horn like a mt122 style, the reason im askin is because i want to put a small rig together for the summer, bbq, mates party's etc. i only really wana have 2 boxes, sub and mid/high and it needs to be as small as possible and cheap as possible cause its only gona get knocked about and kept in the corner lol. thanks alot

You can... but it won't work the way you're planning. The HF "uses' the main driver cone as it's horn, so when you horn load the driver you're horn loading a horn. If you see what I mean. I'd imagine someone will be along shortly a show the science bit. ------------- Chas n Dave : it's like Drum and Bass but with beards. E=mc² ±3dB |

There aren't really many coax drivers out there with very high EBPs and low QTS that I can think of (I've been looking at coax 8s recently). Maybe a waveguide flare rather than a horn may suit more of the drivers out there (the difference is theres no compression). Theres plenty of coax drivers out there that should do more than 120+dB though and that is really rather loud in most situations. Living with horn loaded boxes is a pain in the arse too. ------------- Don't test the champignon sound |

Yeh i had a feeling it wouldn't work, thanks alot for clearing that up guys.
Reflex it is then, wat u reckon about reflex 10" and closed in 8" coax? sittin over a 12" reflex on base.
thanks again

Horn loaded horns have been around for decades. A conical horn can be considered as an exponential horn cut into infinitely small slices where each successive slice, as you move away from the throat, has a lower flare rate.  |

a 10" reflex will crossover perfectly nicely to a 1" compression driver so no need to bother with the sealed 8" mid.
with a 12" sub bass, you could use either a 10" coax or maby a 8" coax, thou all the co-ax's i have looked at, you seem to get a lot more sound for your money when you go to 10" i have looked a lot at the beyma stuff as it's got good sound quality and isn't too expensive, for example a B & C 12" coax is about £500 and a good beyma is about £300
depending on your budjet thou, lets have a cheap ish option first :p consider a eminence kappalite 3015lf (£130 ish) for the sub bass, it moves a lot of air for the money and only needs 450w, then use a 10" beyma coax (10xc25 £150 each) for everything 120hz ish upwards, you could even put all that in one speaker box should weigh in at about 25kg. costings, need to add a crossover, which is about £60 per box. £680 a pair plus material costs of course :D 700w rms per channel, 40hz-20khz average sensativity likely to be around 98-100db 1w1m :D
