No, I meant the BL is way below 20.

hi,does anyone have any specs on the punisher horn.How does it compare with other horns interms of efficiency eg the hd15,the 186. The punisher has a fairly long path ,Rog would you use such a horn in long throw application and in situations where high spl is needed eg outdoors. I am very interested in the design and I am just wondering if there is anyone who can offer some critique for or against the design. Thanks. |

check out the forum - like to see ground-plane of prototype and find out how that Ciare is holding up
"if" typed correct link then will lead to some graphs (assume predictions) http:/www.speakerstore.nl/forum/viewtopic.php?t=36 |

freddy it almost worked-when u click the link its wrong tho http://www.speakerstore.nl/forum/viewtopic.php?t=36 Looks like AJ horn simulation. Note the high cutoff. Efficient High F3 subhorn,as i expected due to HIGH bl 12" ! This isnt a 'single driver labhorn' This is completely different :-) 40hz is ~ -10db at the end,some one asked about the lab12 on it,probably wont work. Lab 12- low Bl,low compression ratio,short horn Ciare- high BL high compression ratio,long horn the 1kw power handling could be handy-aslong as power compression isnt 9db anyway Cheers!

I dont know about the XMAX beyma 12 but the LX60 looks similar. + they list the power compression figure

wow check out the driver search utility on that site-you can easily find drivers of similar spec! http://www.speakerstore.nl/index.php?show=speaker Bl Vas Power Cost Qts Diameter Brand!

My guesstimation. Looks prety good!!! Mouth 2700cm^2 Throat ~ 185cm^2 Length ~2.35metre F3 43 hz Horn loaded at ~50hz.Aslong as the driver is linear,no problems :-) The Small mouth only drops efficiency slightly.The only thing id do,is fold it S style so that the driver is easily accessable eg- Cheers!

The LAB horn isn't what I would call 'short'. It is rather long....

hey mike
how come sim for Punisher in McBean showed diff (higher) SPL than one (AJ?) by Frederik? - were both for 2.83vrms? seems lilke prototype used 4 ohm ciare S fold be nice to load driver without screaming! - how would folding change box aspect for ~fixed bulk? - would V-wedge throat in S-fold work better than V ramps at very top of response? best wishes Forum prediction in August http://home.earthlink.net/~buddhaboy2/PH.jpg |

Il check up if i used 8ohm or what :-) mine was jsut a guesstimation of it anyway. The bulk wont change-the only issue perhaps-is having a Vrc which is too large-because this driver only watns ~20-40litres,and with a big wide horn i may have too much behind it,so partition required,which means waste-or i could minimise the width more,thereby making the horn taller,but not wasting any space ! Thats why the Jbl 15" etc enjoy the S fold-often times they require the large Vrc 60L + anyway so no volume is wasted. The punisher horn has a V wedge throat-but those partitions minimise the Vtc maximising top end-but by that time the horn width + panel resonance are coming into play anyway |
