So, what music are you listening to now?

[BlueStreak]

In the chain used to reproduce this..................

Recorded FM signal from a Dynalab MD-90 with upgraded RF coil to a Revox A77mkIV at 7.5 ips.

Played back from same deck through a McIntosh MA6900 (200 wpc) and speakers made by............

ME.

Basically,

2.5-way, 2nd order crossed over at (IIRC) ~1800hz and 1st order at 15,000hz

15 inch Dayton woofer

1" PRV Polyamide Compression driver mounted to Dayton Audio waveguide.

Fostex Supertweeter.

It's a 2.5 way because the x-over to the supertweeter is high pass only. The waveguide starts to roll off naturally at around 15khz.

The woofers are in a 3 cu.ft . trapezoid Baltic Birch box with 2-4"x 10" flared rear vented ports.

Audyn and Dayton 1% caps used. Jantzen air coils.

I should be getting useful output down to ~30hz through the mains.

The sub is a Dayton Titanic III 15" driven with a 500 watt plate amp. Useful output down to 18hz.
