Macka,

What speakers are you using with your pass gear?

[macka]

Hi Mert,

They are large 4 way JBL studio monitors model 4345.
Overall 10 cubic feet in volume. 300lb each.

Some specifications

32 - 320 hertz ~18 inch woofers 4 inch voice voice 1 inch excursion, 320- 1200 hertz ~10 inch midcone 3 inch voice coil ,1200 -9000 hertz ~ exponential horn with 1 inch compression driver using aquaplas coated titanium diaphragm, 9,000-21,000 hertz ~slot radiater.

Frequency range 32 hertz - 21 khertz @95 dba.

I built up these clones in 2004 with the assistance of the original design engineer Greg Timbers at JBL and some other member on the Lansing Heritage forums.

Its a fairly old design by todays standards but they are impressive when properly setup.

They seem to work well with the Passlabs amplification

Isn't it difficult to drive 18 inch with x250.5? or you have an another pair of speakers?

Mert,

I see the picture... but why is the dog on the amp? And is that
a yo-yo he has hanging in front? Seems like there's a story there.

Looks like your son is famous now too...

Cheers, W.

I have some Dynaudio on loan but I prefer the JBL, freedom from power compression. The disadvantage is they really need to be biamped to avoid response issues around 100 hertz using a full passive crossover.

The plan is to build this design in 2008 and literally play with all my Pass amps. Its an nice easy 8 ohm load and can produce a nearly perfect square wave in terms of phase response.

Actually, it is a hedgehog, it is not a dog. The hedgehog is hanging with me since 2003. Check the pictures , you will get the story....(it is not a yo-yo, its a blue eye, for protecting the all gear for bad luck, murphy law, ....)
