@ linear phase: Perhaps it's a matter of conditioning or definition. Since I was a toddler, I was exposed to live performances by military bands, my mother was a pianist, my father's mono HiFi used a University tri-axial, as a former recording engineer and most recently technical director for...

Frequency response is highly overrated. Some of the worst systems have near ruler flat response in average or better rooms. They may sound 'exciting' but soon fatigue as the brain tries to sort everything out. On a time coherent system, the sound stage is accurately rendered. The experience is...

'clarity' is a nebulous term meaning different things to different listeners. To some it's a tizzy top end. To me, it's coherent arrival. If you walk by an open window you can tell in a heartbeat whether someone is playing an instrument or a HiFi. As a former recording engineer, the best...

Well, this is embarrassing. One thing I thought I had done was setting WASAPI exclusive ON. When I checked the setup, both were off. I turned them on and restarted several times. Everything came up fine and the dB meter was correct. Sorry for wasting your time.

It doesn't matter what driver is used. Java, ASIO4ALL and FlexASIO. I need to use ASIO to be able send signal to the miniDSP Flex Eight. If I use Java drivers I have to load miniDSP Console to configure, then unload and load REW to use USB to send audio, then unload to use Console to load...

I'm always using the latest version and I always get this error. I'm using FlexASIO and UMM-6 and it's PITA to haul out my mic calibrator every time I want to use the SPL meter window to reset the data.

By asymmetric I meant relative to the whole room and shifting the MLP. It appears now that the speakers fire down the room. Perhaps swinging the speakers 30° CCW and moving the sub[?] between them. This assumes the mains are not part of the HT system. A floor plan would help immensely. It...

You might try asymmetric positioning which might tame the 'note' problem at the expense of the overall imaging

Acoustic treatment is a whole 'nother can of worms and not for the faint of heart. Perhaps the OP can post dimensions and images so we can better assist.

Another option is the Eminent Technology LFT-8b. Full dynamic and easily Triamped. New version is more efficient. With DSP XO, room correction filters and time-correction, they are outstanding on everything from Miles to Queen to the London Philharmonic. Subs are Martin-Logan 800x.

I had a look at the measurements, but there's nothing I can tell from them about the sound. Have you tried room simulation in REW to see the effects of various speaker and sub positions? Unfortunately, REW doesn't handle asymmetric room shapes. With your gear, I would forgo any external add on...

@ astolfo: continuous 0-180° phase control means that you can set the phase adjustment to any value between 0 and 180°. Without it, you either need time delay or a strong back to shift the subs. This page covers my 20 years dealing with subs ieLogical Subterranean Homesick Blues To use a Hi...

REL doesn't list the remote control functionality for #25. IMO the miniDSP 2x4HD is superb in the digital domain and mediocre using the analog input. I use two 2x4HD in my tube tri-amp w subs. Assuming the REL has adequate control: Level, CONTINUOUS 0-180° Phase, Polarity, variable XO and...

yes, TWO 2x4HD. One per channel I wrote embedded software and Windoze applications to control the devices. Our devices connected via USB which has a 127 device limit. That one has to plug in, and then tell the miniDSP software to connect is strictly 1980's. Both the old and new plug-ins...

which mentioned miniDSP and measurement positions in the first post, both of which I have a fair history. :wink: I've looked at the AL et al spaces. With a later career as embedded hardware and software engineer, NO computers in the HiFi :wits: From an earlier career as a recording engineer...
