spinorama

With discussion in various development threads on DIY spin turntables I'm picking up on Rick Sykoras suggestion and starting a thread for DIY turntable build ideas. Most use one of the various furniture dolly offerings. Here's a different approach I took using a bolt on front wheel bearing...

So we don't have many spins for dipoles and bipoles. Panels more or less don't fit in the Klippel. So I am wondering if some of you folks can take the data from Amir's tests and show the resulting directional plots and response for in room results along with what Harman score such a thing...

Disclaimer#1: Klippel measurements from us (the manufacturer), not independent measurements. Disclaimer#2: Cleared with moderators that it would be okay to post this thread for specific discussion around the measurements and technical aspect of the speakers. For discussions related more...

I'm guessing this has been discussed before here but my search Kung-Fu is apparently not up to snuff. I'll frame this question as follows: The spinorama.org rankings show that, with EQ and Sub, the $100 Polk XT15 and $75 Micca RB42 perform slightly better than the $5000 Dutch Dutch 8C. I'm...

I had been looking for a low-profile center channel for a while. The Kef T301c was very disappointing, though the Revel C10 looks good--it's simply deeper than I was targeting. The Paradigm Millenia LP 2 retails for $549. The speaker is solid feeling and only 1.75" deep. It has the...

The passive version of this speaker was measured and reviewed here: https://www.audiosciencereview.com/forum/index.php?threads/jbl-control-x-review-indoor-outdoor-speaker.24852/ I noticed JBL made a wireless version of this speaker and thought it would be interesting to measure. It is now...

Data analysis of FBT Promaxx serie FBT Promaxx are PA speakers which are optimised for high output. They are active, relatively cheap, easy to get and have an internal DSP. FBT is nice enough to provide a lot of datas for these speakers. Typical use cases are small gigs, your garage, your garden...

JBL PRX900 are PA speakers which are optimised for high output. They are active, relatively cheap, easy to get and have an internal DSP. JBL is nice enough to provide a lot of datas for these speakers. I used the data to generate the spinorama and derive some information. Here is the...

This is the 5" woofer version that retails for US$450/pair. Erin's review: https://www.erinsaudiocorner.com/loudspeakers/wharfedale_12_1/ Update: Video review --------- Yes, this the same model that Amir reviewed...

These retail for US$300/pair. Erin's review: https://www.erinsaudiocorner.com/loudspeakers/elac_db62/ update: video review --------- Yes, it's the same one Amir reviewed previously...

SoundAndRecording today posted the spin for Focal Alpha Twin Evo: Which retails for US$650/each. It has dual 6.5" woofers. I appreciate that SoundAndRecording started posting the CEA-2034-A graph along with their normal graphs: The rest of their graphs: Discuss!

Can someone tell me if this speaker measures well; and based on directivity index, will it EQ well? Considering these for front LCR’s behind AT screen. Thank you

Thanks to @hardisj for reviewing Polk Audio XT speakers. XT35 center: US$300/ea Preference Score (according to Erin) is 3.9 Preference Score (according to Pierre) is 3.8 XT30 center: US$200/ea Preference Score (according to Erin) is 3.6 Preference Score (according to Pierre) is 3.4 XT20...

This is a quasi-anechoic spinorama measurement + internal amp measurements of the Genius SP-HF3000A (discontinued) powered PC/multimedia loudspeaker. It is quite an old product and there's not a lot of data available about it online anymore - here's one link with some very basic information. 10...

This is a quasi-anechoic spinorama measurement of the Revel M16 passive bookshelf speaker. Although this speaker was one of the relatively early ones measured in high precision using Klippel NFS in a review by @amirm (link), I figured it is always nice to have another independent data point so I...

Hello all, This will be a summary of (many :)) measurements I did with the Neumann KH 120A that I recently purchased. The pair were manufactured in 2013 and sport the older, IMO slightly industrial looking finish: A few notes on measurement methodology: The loudspeaker has been measured at...

Today I finally measured one of my 1st generation JBL LSR305s, using the quasi-anechoic method, and used it to create a spinorama-style report. It is far from the precision of an NFS, but I hope it might still provide some qualitative insight on these pretty common loudspeakers. Some...

This is the first time I remember seeing a spin from any Magico speaker in Klippel NFS. I am glad the company is providing it to reviews, but I wish they uploaded them to their website for all models as well. Behold the flagship floorstanding speaker from their entry level A series published by...

https://archimago.blogspot.com/2021/02/measurements-emotiva-airmotiv-b1.html? I was gonna say it looked poor, until I noticed he only used a 30dB scale. Taking that into mind, this is really good for $230 (the original B1 was $300). Do not use the grilles though. Oh, and he also goes on to...

https://www.audioholics.com/bookshelf-speaker-reviews/rbh-pm-8-monitor https://rbhsound.com/pm8.php $3200 in standard finish, $4000 with side accent panels (made of stone) Not sure why the RBH site shows a silver woofer and Audioholics a black woofer. I won’t post all the graphs, just the...
