This DIY loudspeaker system experiments with multiple small wide-range transducers in a multiway configuration. The idea is to join good directional characteristics to coherence and power handling. Another goal is to improve timing by controlling the phase with FIR filters. Please follow this...

This may prove to be a stupid question, but it's something I haven't previously considered. I attempted searching prior to posting. Can I provide a single wireless feed to two wireless HT receivers (Sony STR-DN860, specifically), in order to have the ability to dial in each receiver for it's...

I’m trying to determine what the total potential (textbook) output would be at a given frequency for a few different Sealed Subs. They will be optimized with MSO, however I️m trying at this point to determine a total potential SPL Here’s what I️ have: All SPL values at 16hz and Max Burst...

Hello, I would like to perform a phase measurement at the LP. But I have some difficulties to interpret the IR response: 1st: There are 2 impulses quite similar within 1 ms. When I'm pressing "Estimate IR delay" sometimes the second is selected... So I don't know which one I should select in...

I just discovered REW and it is a fantastic tool. I joined because I have a problem. Everything seems to work EXCEPT taking multiple measurements. On the first measurement, I set the levels and I go from 0 hz to 5000 hz with 1M samples which takes 21.8 seconds. It works great and gives me an...

the new [FDW] suffix on a measurement, in beta 11, seems like it gets added repeatedly in some cases and not at all in others. It looks like it adds it to a measurement every time the ir window dialog is opened and an FDW is activated so you quickly get a measurement name like CW [FDW]...

Hi All. I have 2 subwoofers in corner cabinets and the only good place to put them in my room is the front corners behind my main speakers. I'd like to figure out how much gain I am getting from them being in the corners. I have BASH 300 plate amps in each cabinets and I can add or reduce...

I already use REW to improve my listening space, but I also wanted to use it to measure my HRTF. I realized it's doesn't seem to be possible to measure with 2 microphones at the same time. Is it possible? If not, any idea of a work around, based on REW, to achieve that? An idea: can I...

Hi All - this is my first post here and I'd like to solicit your opinions about how to best manage all the eq on my loudspeakers sets. I run all the audio in my home from my mac-mini via HDMI, 2 USBs and Apple TV all going to different amps and speakers. I'd like to apply unique equalization to...

Ok, so I decided to do some EQ'ing of my system. All subs are crossed to the mains at 100Hz in my AVR. Equipment: (All subs are receiving the full low end signal. No crossovers between them.) 1x JBL 4645C clone 2x Martycubes with Dayton HO 18's 1x 25Hz ported box with 2 Infinity 1260W's 1x...

I'm planning a room change and it seems that multiple smaller subs might help to supplement an existing pair of sealed 15" subs I have already built in particular to help with 60Hz and 90Hz nulls. This is based on room measurements and comparing with the REW room sim, which is pretty accurate in...

Hello, Well, I made it through the intimidating signup process. :sweat: I just started using REW 5.13 today and it's been good fun, but I did find a problem. I didn't simply use the default settings for the frequency scan, I had to crank it up to the max samples and multiple scans to see if...

Hello, I'm using REW 5.13 under Windows XP SP-3 and I'd like to use My Audio GD DAC as output together with my Digidesign Mbox 1 with phantom power connected to my MIC for Input. Both peripherals have ASIO drivers and I can setup and make them working fine separatly but setup using both...

Is it possible to at least run two instances of REW with preferences set to different inputs, so that I can see 2 RTA graphs at the same time? Preferably to have functionality from 'All SPL' view in RTA. My usecase is a dance studio, where I assume the response should change a lot when it gets...

The preferences check box to deny multiple instances of REW to run has been removed. The capability to run multiple instances has also been removed. -- I like the ability to run two instances, to compare signal (at preamp) with room result (using UMIK-1) with the RTA windows in two instances...

So far I haven't been able to figure this out and sometimes the sub will play with the speaker and sometimes it won't. Is this more of a AVR setting or is there a setting in REW to do this? I was really curious as to the response of the L/R together just for curiosity sake.

Current setup: Two Klipsch RT-12d subs used with an AV8801's Audyssey SubEQ HT, setup with an Audyssey pro kit. I really like what SubEQ HT does for my current subs. I also love dynamics A review with measurements of one of my current subs is found here...

Hi All, Up front apology for the long post with some busy graphs. :bigsmile: (REW is GREAT!) I have finished up a DIY Transmission Line subwoofer and planning to integrate into the rest of the system as best as I can. System details below. Speakers - Definitive Technology - Front L/R...

Hey Everyone. Been a HTS member for a while now although I don't post a tremendous amount, I read through many threads ... mostly in the home theater section and I've built a couple home theaters (see my threads if you like ) Over the past year or so I've been looking for something that would...
