Nice subwoofer can make your speaker sing!

I had been using Lansche 4.1 since 2007.

It has pristine treble out of with plasma tweeter and nice bass out of two 10 inch active woofer and high efficiency(99db/w spec but real no is close to 95db/w) suitable for Small power SET amplifier.

Although it is pretty dynamic compared with most speaker, I had been lusting for more dynamics and powerful bass.

I got used Scaena 3.2 speaker January this year.

I had to be in Korea during February to attend funeral of my mother.


But I could not assemble main tower yet without someone helping me during lockup.



Thus I started using its two 18 inch carbon and kevlar composite subwoofers in addition to Lansche 4.1.

I use digital crossover of Lyngdorf 2170 to feed 40 hz up( highpass)
to Line Magnetic 508 for driving Lansche 4.1 and 50 hz down to two bridged Crown XLS 2502( 2400W for 4 ohm) for driving two 18 inch subwoofers.


Now I got solid bass foundation, more natural dynamics and deeper soundstage.

Line Magnetic SET amplifier(48watt) sounds more clean and relaxed without need to drive subbass signal under 40 hz.

Nice thing of Scaena 18 inch subwoofer is that it sound tight and fast but not overbearing or bloated.

Someday, I need to assemble main tower of Scaena speaker to place them side by side with Lansche 4.1.

But now I am so happy with the sound out of
Lansche augmented by two 18 inch subwoofers, I am not in a hurry.
