Seas Exotic X2-08 ;T35 out of stock

in Madisound .Any of you rich guys is playing with "the exotica" ??

Difficult to seriously consider ordering them when i don't get the madisound X2-08/t-35 vented box plans. They looked promising for low watt set's due to a higher sensitivity then their exotic fullrange driver but the supplied box plan shows bass dropping off below 500Hz. The X2-08 almost mirrors the factory measurements from 500Hz down.

I like the "idea" of a easy to place high WAF, 94db 2-way "smaller" than the adv. comparable size fullrange driver/BLH, for a change of flavors if these can do that.

So, can anyone here take the time to run a box simulation to see what the bass response could look like in a larger vented enclosure?

Also any reason why a Audax TW025A26 or TW025A28 couldn't be used to get the ball rolling and then upgrade to the exotic T35 at a latter point if you fell the need to?

A lot of the drop off you're seeing with regards to bass roll off, isn't the bass at all.

The way SEAS measure includes bafflestep - that is to say they measure speakers in boxes, rather then huge 'infinite' baffles.

now you're confusing me and i don't get it. are you saying that the box plan provided will be relatively 94db out to a 80hz or so roll-off? or for that matter that a F8-X1-08 will be 93db till roll off in the rec. 60L. sealed box because that's not what their plot is showing in the plot of it in a 60L. sealed box dotted line, see pdf brochure SEAS Exotic X1-08, F8, 8 ohm, 8" Full Range Driver from Madisound

No.

What I am saying is that above bafflestep you will have a 94dB speaker. Then as wavelength increases with decreasing frequency, the baffle width starts to become insignificant with respect to the wave.

Due to this you get a 'step' (more like a 'slope' in reality because the transition isn't instant) occurring, where you lose 6dB of output as the radiation of sound goes from hemispherical to radiating in a complete sphere.

To compensate for this you pad down the highs. The reality is that a 94dB loudspeaker, measured on an infinite baffle, will end up being an 88dB speaker.

At a guess the dotted line SEAS draws represents a real world sensitivity, after baffle step has been compensated for. (You don't typically need 6dB, this figure depends on room placement and to a lesser degree drive unit itself) So really you're going to end up with a ~91dB loudspeaker.

Usually SEAS overlays the dotted line above the bafflestep transition. But from looking at several data sheets it appears that the placement is sometimes done at random.
