As the forum usually concentrates on the larger boxes thought you might like to see a box ideal for the weekend warrior doing Weddings, Karaoke etc. Just a simple twin 8" + 1" comp jobby . Usable 120-20000hz 400 watts 99db/watt Although this uses BMS drivers it could easily take similar from any of the quality manufacturers. I use these with a single 15" reflex a side and they cope with up to 150 pepes doing all sorts of duties easily. Tony    |

I should also have mentioned that the grills were supplied by Markie (always a pleasure to do business with) and the cabs were fabricated by Dom (also a really nice guy to do business with) so really an SP Forum project. Tony |

Look good, nice and neat. How do the rear ports perform? Do you have to have them a certain distance from a wall? Just curious

Yes, its usually stated that it should be the distance of the dia. of the port so in this case 50mm. I cross these at 180 hz when used with the 15" ers so the output from the ports is very little anyway. Only when used at the lowest recommended X-Over of 120hz do the ports really do any work. When used on their own in a smallish room and close to a wall they sound pretty good with a bit of boost from 50-90 hz No real bass but plenty of illusion. Tony |

Ryan, Just PM your proper Email address and I will send you a PDF. Tony p.s. A pair of these on stands either side of the DJ would be bloody loud. |

Hi Tony, did you have a certain reason to make them bassreflex cabs? got some simillar ones but closed, still go deep enough (120) and have some kind of integrated subsonic as the cones were kept from moving too much on bass. just curious why you put ports at the back as it wont be recognizable as tops or monitors in bit bigger locations (at home i could understand but not PA) would like to hear your opinion about that cheers |

maybe, but in my opinion theres no need for a port if the speakers go down to the required crossover-point in a sealed enclosure, makes operation much safer and reproduktion much more natural as you dont have tendencies for boomy bass or overexcursion because of equing etc. hope u get what i mean and i am still inerested in your opinions... cheers |

Driver optimised for reflex. Box can be used on its own near a boundary with a small amount of EQ. Poor bass performance if not reflex loaded. Rear ports = Low port noise, optimal position, cabinet cooling + most importantly, I like it that way. Boomy bass is a function of driver/cab design not applicable to all reflex designs. Over-excursion is an operation error nothing to do with driver or cab design. Tony |

Nice job Tony. Your cabs are very similar to mine, Eminence Beta 8 and B&C DE12 loaded: http://img44.imageshack.us/gal.php?g=p8240001o.jpg ------------- love begins below 40Hz |

Very nice looking cabs. Are they for home use? The very first pair of double 8's I built about 10 years ago had Beta's in them. Still going strong. The D12 is a superb driver, one of the best comps I have heard. Tony |

Tony I'm interested to know why you went for a 2x8 rather than a 1x10 or 1x12. I'm guessing the boxes are around 40 litres so a single driver could be an option. In fact BMS quote superb performance for the 12N620............. -3dB of 60Hz in a 25 litre cab. ------------- If it's got wheels or tits it's gonna cost a fortune |

Mark, The boxes are actually only 20L net. Two reasons really, the fact that the 8" drivers sound pretty good run up to 3k which means I can safely use a BMS 4524 comp and also they have amazing clarity thru the vocal range. The total price of a double 8" box or a single 12" box would actually be pretty similar due to the fact that I can use a less expensive comp with the 8"ers. I agree that a single 12" is more flexible in that it can be used on its own, but if a sub is always going to be used then I prefer the twin 8" ers. I always think that single 10" is too much of a compromise even only on vocals without a sub Tony |

Tony, they are for home use and small parties. Subs are 2 ported 12LX60s. I think 15" subs are too much for 2x8". ------------- love begins below 40Hz |

how much do you reckon it would be to build two of these? loaded and unloaded. Could this kind of box size and design run full range? If not, what sub(s) would you use with a pair. also can you email me the plans to dj [dot] dunc [at] gmail [dot] com thankee |

Got to disagree with you on that one. For live music up to 150 pepes, mike'd Kick and DI ed bass and keys with just one Vocal then the 8" ers just about give up at the same time as the 15" subs I use crossed at 180hz. However on modern recorded music then the 15" are at the limit first. You would need a pair of the Beyma's you have a side to get the optimum output from the system but I personally would need more sub. Tony |

Tony, some subs sound bad when crossed high, including mine. I cross at 100Hz, IMHO 2x8" and 1x12" is just right ratio.

Yes that makes sense, I use the BMS 12N630 which is quite happy to go up to 200hz. That then takes the load off the 8" ers. Also the Xmax on a Beta is 3mm and on the BMS 8" it is 5mm. They also cost nearly 3 times as much so I would expect slightly higher performance out of them .Tony |

Hi Tony, thanks for the Q 12 plans, have the cut sheets all sorted but now looking for MTs -- looking to use some 8"s ..... was thinking of Eminence simply on price and this thread sounded interesting....... any chance of some help with plans on these too... George C
