Re: Bfm old fashion design?
Looks nice, pretty clever folding style... but compare to which cab, the frequency range does not match any of the cabs here. But if you count packspace 2 slim T60's would be about the same size and also have sub 30hz output.on1sony wrote:http://www.danleysoundlabs.com/products ... bh/dbh218/#

Re: Bfm old fashion design?
It might outperform a dual loaded T60...but $ for $ and # for # probably not.

It ought to.....it can take 4+ times the power as a dual-loaded T60. But, money, weight, and the amp it would take to run one of these.....

Re: Bfm old fashion design?
Something doesn't add up here:
"continuous output
141 dB SPL
peak output
147 dB SPL
sensitivity
117 dB SPL (2.83 Volts into rated Z, at 1 meter) measured in half space
Power Rating
3600 Watts continious, 7200 Watts program"
117dB at 1 watt, and 141dB at 3600 watts??? That 24dB increase should be had with only 100 watts (and the 147dB at 400 watts, not 7200 watts). Of course we all know we can't believe the manufacturers claims, but come on.

Re: Bfm old fashion design?
For one, the 117db @ 2.83 volts was probably measured at 2 ohms, so its actually about 4 watts, not 1 watt. That doesn't explain everything though.67baja wrote:Something doesn't add up here:

Re: Bfm old fashion design?
They don't compare because...
It's a 33 Hz horn. That's T48 territory...and it'd take a good pile of 'em to plunk down the same output as the DBH.
Each design serves entirely different markets so there is no compare. You're not going to see anyone trying to fly 8 T48's anytime soon.
For starters, comparing it to the T60 is all sorts of wrong.on1sony wrote:Putting aside weight and price...

Re: Bfm old fashion design?
112 + 35 - a few dB for power compression = 141. Nothing more to it.67baja wrote:Something doesn't add up here..... Of course we all know we can't believe the manufacturers claims, but come on.

Danley, unlike most other manufacturers, posts specs that actually err on the conservative side. The reason you see that "peak" crap listed is because you know there's a bunch of horny 20 year-old sound techs that wouldn't let them sleep at night if they didn't say otherwise.

That, and they hope said dufuses (dufi?) will actually try it so they can sell 'em some replacement drivers.

Two T60s, dual LAB 12 loaded, versus a DBH 218. Similar size, weight and impedance. Not a very similar price, though.

Like most 18 loaded subs the DBH 218 has too short a horn to go really low. A better comparison would be to a pair of 2x12 T48s, which would at least match it in a similar pack space.

Re: Bfm old fashion design?
The -10db cutoff is 28hz... Which makes it T60 territory. As the lowest frequency with Bills cabs is also atleast 10 db down.Radian wrote:They don't compare because...For starters, comparing it to the T60 is all sorts of wrong.on1sony wrote:Putting aside weight and price...![]()

Re: Bfm old fashion design?
33 hz might be in the t48's region, if it weren't supposed to be high-passed @ 40...Radian wrote:They don't compare because...For starters, comparing it to the T60 is all sorts of wrong.on1sony wrote:Putting aside weight and price...![]()

Re: Bfm old fashion design?
Unless you hit the 4 pack stack then they drop to 35, then it is a 2hz difference. Starting to split hairs and write your name in the snow.osse wrote: 33 hz might be in the t48's region, if it weren't supposed to be high-passed @ 40...

Re: Bfm old fashion design?
And to top it off it looks like the 117db rating is at 95hz or so. I would rather have the 105db at 25hz from the T60's and the giant pile of cash that's left over to put in the mouth of the T60's to see how far I could shoot it across the room

Re: Bfm old fashion design?
I see what they did there. It's really sad that a name like Danley has to make designs to meet rider specifications rather than what they may have been optimal.Also using a pair of 18” drivers meets rider compliance issues while still yielding vastly better performance over competitive designs.
