Hello everyone. (this is a bit long for sure!)

Just joined MLO and it was suggested to post into this showcase thread.
It is a 2.1 system comprised of a pair of Martin Logan Classic '9's from the Masterpiece series. Driven by John Curl designed (Parasound) Halo P6 preamp/DAC and the A-21 amplifier. This is mated to a Martin Logan Dynamo 1600x subwoofer and tuned according to the built in Anthem room correction with the optional 'bass kit'.

The electronics are in a low rack at the seating area as shown. The preamp with balanced quad lines run out to the amp along with a 12volt signal cable. The subwoofer is keyed by a 12v. signal in turn from the amp. The A-21's audio output also drives the subwoofer's input which according to ML and stated in the manual, is the best way to 'drive' the 1600x.

The 1600x is then fine tuned to taste using the Martin Logan app. on a tablet. Crossover set at 35 Hz. Phase 90 degrees and input INVERTED. This is from the manual as a starting point, but, so successful (I can't make it sound any better!), I continue to run it in that configuration.

Turntables: Red table is a Rega RP6 with Groove Tracer subplatter / jeweled bearings - external powersupply and speed control.
White table is a new U-Turn custom order (made here in my own state). Both sport an Ortofon Blue cart.

For CD / DVD-A / Bluray audio: Pioneer Elite Multi Disk player and a cheapie Sony Bluray player for that format.
Cassettes are handled by a Realistic SCT-11 bought new in the 70ies - 6 new belts a few years ago.
Streaming from Qobuz via a dedicated W-11 laptop with USB to the Halo P6 DAC.

The room is lighted by overhead spotlighting focused on the gear, and uplighting by floor cans at the front wall (with remote LED control) to highlight the panels from behind in most any color combination as shown in the photos.

Sound treatment: A custom order, 7x4' cloth cellular window covering front and center wall. Further absorption along the side and rear walls in the listening end of the space but NOT near or behind the ESL's according to ML. These are custom ordered 2x3' panels from ATS filled with Owens Corning materials. The room is a combination of live and dampened acoustics which help to keep from choking the dynamics, yet controlling echo at the same time.

The Classic 9's and Parasound gear were all put together by my new, brick and mortar audio store 'Safe and Sound'. They have a fine website, complete with photos from their Grand Opening party which I was happy to attend and actually meet a fine people from Martin Logan.

The photo of the space with both turntables is the current config. and was also sent to PS Audio.
Thanks for taking a look!

Gary

Excellent setup. Awesome pics and lighting effects. Did you do the system setup and sound treatment yourself?

Hi Gary, lovely looking system; thanks for posting.

Checking that you are indeed driving the sub from power-amp levels as input?

Since you have a 2.1 capable preamp with a full high-pass / low-pass active crossover, I would suggest leveraging that and feeding the sub-out signal (via balanced XLR) to the LFE input of the X1600.

It is always best to use an active XO if available, as that will remove the low-frequency load from the Classic 9.
Given that what you have now is doubled bass, the XO point might be higher than the 35 you currently set. I'd start the XO in the P6 at 70Hz or so.

Cool, as that is important given how close the seating is to the rear wall. From the pic, it seems the MLP seat does not have an absorber behind it, was that a choice?

Usually, the short reflection times from the solid surface just behind the MLP would be a problem.

As for a live front stage, it is definitely an option many enjoy. Have you experimented with the speakers further into the room?

Also, can't tell from the pics, but the toe-in seems minimal, but maybe it is lens distortion that makes it look that way.
