| Open Baffle Experience I heard the Spatial X4s and Linkwitz LX521s at Pacific Audio Fest, and both sounded excellent. IMHO, the X4s were the best sounding speakers under $10K, and the Linkwitz were among the top rooms at the show (not my favorite, but certainly among th... | |
| Open Baffle Experience GR-Research offers a model called the NX-Studio which are designed for applications where the speaker can't be placed at least 3ft from the front wall. These are a two-way design with an "open-baffle" planar-magnetic tweeter and sealed woofer. The... | |
| Open Baffle Experience When I first set up my open baffle system, I used GIK absorber/diffusers behind the speakers on the front wall. These are absorption panels with a plate mounted on the front with various holes. They are supposed to absorb low frequencies and scatt... | |
| Open Baffle Experience @mwatsme - yes, I agree that a narrow baffle helps make the speakers disappear by reducing the front baffle reflections. I think the wave guide used by the X4 does reduce the affect, but probably doesn't eliminate it altogether. I listened to a fe... | |
| Open Baffle Experience @mwatsme - I don't believe the Spatial X4 uses a horn. I think the tweeter is an AMT design with a wave guide to control dispersion, but operated as a dipole (i.e. open in the back). | |
| Open Baffle Experience @mijostyn - I assume you haven't heard the H-frame open baffle sub system developed by Rythmik and GR-Research. I do use REW and a calibrated microphone to set up my subs. There are some minor room modes to contend with, but with a little parametr... | |
| Open Baffle Experience @mijostyn - Your projects sound very interesting, but I have to disagree on the notion of OB subs. My open baffle subwoofers work exceptionally well and integrate seamlessly with the open baffle speakers. Each subwoofer uses three 12" servo contr... | |
| Question About Capacitor Upgrade in Tube Amp @calieng - the primary purpose of the bypass cap on the power supply electrolytic is to shunt high frequency noise on the B+ rail. I doubt it will have any affect on the high frequency response of the amp. The value of the cap is really not that s... | |
| Open Baffle Experience @peter_s - it was the X4 you heard at PAC. That's where I heard them as well. They were pretty impressive, particularly for the price (~8K). Don and Jay from Reference North Audio built my Line Force cabinets. They make a lot of the flat packs f... | |
| Question About Capacitor Upgrade in Tube Amp NOS Allen Bradley Carbon comp resistors are all the rage for tube guitar amps. For their warmth and organic tone. I wonder how they fair in hifi? They do tend to drift in value a fair bit. So maybe not so good in hifi setting. Carbon comp resis... | |
| Open Baffle Experience I've owned a number of Magneplanars in the past, but my first real exposure to open-baffle was when I built a set of GR-Research NX-Oticas with OB servo subs a few years ago. This has been the most enjoyable system I've owned. I recently replaced ... | |
| Question About Capacitor Upgrade in Tube Amp The Vishay Z-foils are very transparent and low-noise. These resistors can be ordered in arbitrary custom values from Texas Components. The latest version is the TX2575. These are only available in sizes from 10 ohm to 100Kohm. The older TX2352 is... | |
| Error message when reordering components in Virtual System I was able to get it to work by logging out and back in again. | |
| GR-Research Line Force First Transparent Speakers? @jerryg123 - Thanks. I haven't had a chance to work on optimizing position or sub settings yet, but just plopped down they sound stunning. The detail is better than my Audeze LCD-2 headphones and vocals sound like the singer is right there in fron... | |
| GR-Research Line Force First Transparent Speakers? @bdp24 - Thanks. I might have mentioned that I owned Tympani IVs in the mid 80's. I used Entec subwoofers (one of the first servo controlled designs), but I was never able to get these to fully integrate. I imagine that your OB subs work MUCH bett... |
