Loving google sketchup at the moment, loads easier to use that catia and lets you play around with ideas pretty quick. This is a mid/top i'm working on. Based on fairly standard tried and tested horn loading configs, but the idea it to be able to make the whole cab and horns from wood using cheap easily available drivers and parts. Maybe not the quality or loudness of simmilar cabs but two a side would give enough spl and coverage for a good dancefloor. But it DIY! and i Tried to make it look good too. 60x40 dispersion. 50cm width, 75cm height 40-50cm depth (still designing it!) Low mid is a 12" reverse loaded reflex horn covering 100-450hz. I'm going to proto with a P-audio SN12MB High mid is a conical horn using the Eminence 6.5" closed back lines array driver (alpha 6 cbmr) and covers 450-2500hz High is a 1" on a eminence LT250 or fane 60x40 CD horn  Ha, I get so excited designing new speaker I have to share it with you guys :) thoughts, comments, discussion... its work in progress so have a while to go yet. Lookin forward to knocking up a prototype in june Thinking of calling it the DMT :D ------------- Minirig portable soundsystem movement |

yea, horn response says so - as long as i can get the driver chamber volume ( front horn chamber) small enough (around 5L for 400hz corner). There's ripple in the response but its fairly smooth 100-400hz at 106db 1w1m 2pi +-2db. The reflex gives you the extra low end you'd never normally get from such a short horn. Fitting that driver in with the mitred panel there and getting the volumes right is the tricky bit! ------------- Minirig portable soundsystem movement |

Sketchup skiiiiills there Dave. Does look very nice indeedy. You built one out in NZ then? Ported horns can work for midtops - omnitop12s have quite a few fans (then again I am biased in this though). ------------- Ay, Uncle Owen I'm off down't Tochie Station t'pick up some power converters |

Thanks for sharing your ideas D, but I have a few questions, a)A 6.5" can cover 450-2k, but can it do this at high SPL, without going bang? Wouldnt 10" be better? b)A Number of subs perform best when crossed out about 80hz, Wouldn't 15" kick section in your cab be more compatible with this, and move more air? ------------- "Who am I?

Is it absolutely critical for phase bung to be in contact with cone? Even if the horn allowed use with 4x different drivers, would be better than bein restricted to 1x. Not every one wants Paudio driver, or to spend big bucks on 18sound/PD. Few of us like choice of B&C, Beyma, Fane, Celestion. ------------- "Who am I? I'm the guy who does his job..

thanks for the comments as i said, i'm not trying to make a really really loud concert cab here, just something thats compact, fairly cheap, buildable and sounds good. I chose the 6" because its easier to get it to go high without a fiberglass phase bung - perhaps it wont be loud enough and i'l have to try an 8". Its a 12" because a 15" wont fit in this trap config and will struggle more to play high enough. I'l post the hornresp plots and you can take a look. i gues I wont know how it sounds though until i get buildin Mykey, have you had a look at the RCF 8" mid range neo sealed back driver? If i was going to make a fiberglass mid range horn i would use that driver! pricey though- which is why i haven't used it here. ------------- Minirig portable soundsystem movement |

Good work!
Have you done much work on the 6" section yet? Just wondering why you chose a conical horn? It'll be much easier to construct, but does it not lose a lot of low end? I looked at that eminence driver a while ago, but it seems difficult to get hold of in the UK, like all the other suitable 6" drivers. What sort of compression ratio are you looking at?

Looking good davey, reminds me of the FK1 RES2 a lot. What is the divider in the mid horn for, is it to reduce the wavelength of throat reflections? Or is it just to hold the phaze plug?

looks nice, the closed back alpha 8mr i think? may keep up a bit better, if you needed more power. rounding over the edges of your conical horn for mouth/ baffle correction will help reduce high order modes, if going conical it could be worth trying out an oblate spheroid, or make your own to achieve smoother off axis directivity.. i too am making my mid tops atm, but its kinda too late for me to try out le cleach or spheroid flares i been reading up about, but may be of interest to you though. ------------- Subs + Barges = :) http://www.metaacoustics.com" rel="nofollow - www.metaacoustics.com |

shame bout that sn12b - sounds great in our porn horns! Yea, the middle piece is just to hold the phase bung. Its just an idea and i'm going to try a few different ideas out. I want something that can be built fairly quick and simple without a laythe or hours of sanding/planing. The alpha 6 models better than the 8 with higher efficiency and smoother response. but i'l try both - the truth will be in the building and measuring. ------------- Minirig portable soundsystem movement |

| Hi marjan.the drivers are 8mr eminence on high mid, cp650ti beyma mounted on B+C 60-40 horn on highs and the low mid is 2x12 beyma g250r.They go quite well(I think so)and they throw nice clean vocals out to the end of my multicore no problems.we saw 110-113db at the mixer(32m)last year when tested by health and safety federales.I would love to try 18 sound neo driver in mid but at £140 a go they would have to be stupendous to be better value than £20 8mr not sure if it,s worth it.. |

interesting looking cabs,have you taken any measurements? i would imagine a massive amount of diffraction and standing waves caused by your comp taking so much space, and uneeven loading on the two g250r's. also, not really in line with the topic title is it, especially as you have another thread dedicated to your cabs already. ------------- Subs + Barges = :) http://www.metaacoustics.com" rel="nofollow - www.metaacoustics.com |

phase alignment you mean - you measure the phase shift (usin digidrive to adjust time difference and mic to measure ) and then correct for it with the right components in the crossover. cool. Have you had chance to do any outdoor testing/measuring on the usb2? ------------- Minirig portable soundsystem movement |
Posted By: tomschute
Date Posted: 04 May 2009 at 5:04pm
i getcha - i understand time alignment is a device to get things in phase but surely having comp and mid at different distances will cause them not to be 'in time' this is something i have always not fully understood when wanting to construct passive xovers for horn loaded mid/tops. is it not an issue with such short distances and in a pa context. ------------- Out to lunch... stableaudio@hotmail.co.uk www.stableaudio.co.uk Speaker Building Services |

A good link I've read a few times - well answered. So in short there will always be an absolute phase difference (time delay) but as long as this is low enough (less than 1ms apparently for 2khz) then it is not audiable and therefore you can live with it. It is the relative phase difference which introduces variations in the speakers frequency amplitude response which you can hear and need to minimise. Yes ideally using a digital time delay to eliminate this absolute phase shift would seem better than living with it and using a passive crossover. but if you can't hear the difference - is it worth the extra crossover channel and amplifier? you decide ------------- Minirig portable soundsystem movement |

Hi Davey hope you are having fun making sawdust atm and bashing out a prototype if you are not too busy in the shed is there any chance of a close up on the phase bung thingy on the 6" ?? P.S. what program did u use for modeling the boxes?? |
Posted By: mstep77
Date Posted: 21 May 2009 at 6:28pm
|
He's using hornresp i think. When modelling mid tops in this programme be careful on the spl screen to click 'tools' then 'directivity' then it asks you for which angle you are listening at. In general this will be 0 so leave it and press ok. This will inprove the response a lot. It is not so critical for bass horns as they are mainly omnidirectional.
The directivity feature is available on the later versions. It's also very useful for working out dispersion.

cool, i'l make up a zip file with the cad files. You'l need the hornresp plots too, the mid range isn't really finished, there was still some work to be done on the phase bung. There's also a slightly different version which i prefer. Regarding the 15/12/2" it'l probably be quite a redesign. It took a long time to get everything to fit and to model properly with the 12".

After hearing what few people have said about H3 SPL in other thread, started considering idea of shoe horning most of the MT121 into cab with similiar layout to yours. No phase bung though. I'm thinking if 15" section can reach 200hz, shorter 12" straight horn/smaller mouth will be needed, which should also increase upper rolloff? ------------- "Who am I? I'm the guy who does his job..
