    Martin Logan 13A's and a subwoofer pairing question.

    I have 7.4.4 setup currently. For movies as Full Range [Large] and I also route Bass from Center to Fronts [gives very special sensation of very large center speaker] For Stereo - I do Xover at 50Hz and play as 2.4 [this is room specific as I have deep null on combined stereo between 35-40Hz in...

    Martin Logan 13A's and a subwoofer pairing question.

    There are lot of really good subwoofers out there, it seems to be mature technology and you if you go for technically competent sub, you can not do wrong. ML is one of those companies, that produce really good subs, but also other brands mentioned are OK. I personally prefer to stick with sealed...

    Impressions Setup - Flashlight Technique

    My life hack for toe-in - I use 2 stickers - one in front was used to have exact match to 1/3 distance [so aligning with flaslight] Now I find much ore useful to align sticker on the back with panel side - if I have stickers on both speakers in the same distance visually, I know I am doing it...

    Expression 13A, Source, Motion series Atmos tops and sides

    Same here - approx. 7dB lower gain than front subs English not my first language - "architectural panels" might get it wrong but it goes like this lowest row = 2 fabric square modules [each had diff. color - fixed and replaced] - 2x T50 - 50Hz Tuned membrane bass traps [custom tuning] above...

    I need a cheap temporary power amp, any recommendations?

    Look at something with HYPEX NC500 module. https://www.audiophonics.fr/en/power-amplifier/audiophonics-lpa-s500nc-amplificateur-stereo-class-d-ncore-2x500w-4-ohm-p-15016.html

    Final Treatments and 3rd sub added. Almost good ;-) Bit of tidying of cables etc. For those interested about treatments - all from GIK Acoustics: Front Wall: Corners 4x TriTrap with Scatter Plate, Behind speakers 4in absorber with scatter plate with Air Gap, Tuned membrane bass trap for...

    Use of Rear Feet to Adjust Tilt

    I got the best results going "all-in" and having panels in vertical position. Probably all depends on relative height of your listening position vs panels. My sofa is quite low, ears being at around 90 cm listening distance 2.7m

    Expression 13A, Source, Motion series Atmos tops and sides

    I have thrown some money also on the looks - rear wall - all of the panels have incorporated diffusion [either visible or hidden beneath fabric] Those rectangle things behind the LP are tuned membrane absorbers - top2 for 40Hz, lower 2 for 60Hz and front side - black hole ;-) - one Dynamo...

    Looks like I can declare at least a draw [if not an outright victory] in my war with bass resonances. After help from nice people at GiK this is how my room measures now in terms of resonances - Expressions + 1100 + 800. Difference in sound is just astonishing. ML now can really shine, without...

    Iso Acoustics Gaia 2 on Summit's ??

    I am thinking of those too - for 13a - I always wondered if you can adjust the tilt of the speakers. I have best results with panels being set to be vertically. any experience, anybody?

    Tilt wedge for Motion 30 (and Motion 50xTI soon)?

    I use this one - from IsoAcoustics https://www.thomann.de/de/isoacoustics_iso_430.htm tilt up to 6.5 dg, fits ideally for 50Xti + gives real stability

    New panels - yet REW thinks they're rubbish!

    I would not worry - Panels are notorious for measuring poorly and sounding very well. This is mine Expressions - you can see huge dip around crossover, which is really visible only in measurements in listening position [and is a function of mic placement]. I really use REW just to measure bass...

    Center channel options for Esl 11s

    I have settled for 50xti with Expressions. Sealed Bass Reflex with foam. Cut-off at 80Hz with dedicated Purifi amp.Running it 1.5 dB hotter than Fronts, it creates quite full sound stage (45 cm from floor, angled at listening position). Look at my thread in Newbies.

    Expression 13A, Source, Motion series Atmos tops and sides

    I buy most of the stuff either on thomann.de or on Gik Acoustics. My experience - those "pro" oriented shops are much cheaper, without audiophile surcharge. If you look for living room level stuff - nicest things I know come from Artnovion, but they are quite expensive, compared to GIK...

    Expression 13A, Source, Motion series Atmos tops and sides

    Finally, got guy with a pro thermo-camera, who was willing to drill into my ceiling [and has got enough insurance coverage]. This is when this old joke comes to mind [Invoice Total 500 USD - 1 hit with hammer 5 USD, knowing where to hit 495 USD]. Got myself 2 VESA TV ceiling mounts. I have...

    yes, this light colored carpet is on top of my "things I would do differently if I was wiser then" list. Initially this room was supposed to be stereo listening room and it morphed into home theatre only during last 2 years. Also I should have painted at least front part of the ceiling black...

    Motion 50Xti Frequency Dip - anybody having similar experience

    so - it really seems to be some crazy comb filtering coming from adjustable sofa, this is how it looks 1m distance ungated. Crazy dip disappeared. I am bit limited in "change the position exercise" I will try to experiment with first reflection point on the floor unfortunately...

    Motion 50Xti Frequency Dip - anybody having similar experience

    Wanted to ask a specific question on Motion 50Xti - although I am happy with the sound, when measuring with REW, there is some weird dip around 200Hz Is not room related, as other speakers do not suffer from the same room mode. On top I can see quite high distortion peak in the same frequency...

    Small update for front section- just cosmetic one - new custom made stand for Center. Now Experimenting with Subwoofer de-coupling - Now Experimenting with Subwoofer de-coupling - works pretty well, actually, I have settled for down-fire multi sub solution. I can go with higher SPL without...
