Revel F228Be Review (Speaker)

[eyes-on-you]

Did you measure both at once? If so, it's likely interference between the two speakers. Unless you're perfectly centered with the mic, you'll get interference in the tweeter-area. Measure one and one separately to assess high frequencies.

yes, measurements taken while both speakers playing.

Did you use moving mic or is this a single position

Screenshot from one position, sweetspot.

In the REW data, you will find 6 different measurements. Top is sweetspot.

Others, Umik is positioned parallel to the listening positions.

Just guessing, maybe it’s rear wall or side wall reflection

My room is asymetric. Big diffuser located on the front wall. Broadband absorbers located near the diffuser and behind the each speaker.

Left of speaker is open area, no sidewall, right is big window, glass.

I would try moving mic to get the average response around your listening position. A single measurement is prone to cancellation effects which are not heard because we have two ears and also are never exactly still. You can also average the 6 responses, though moving mic will give you a better idea in one measurement cycle.

Also to remind people from the F328 thread, Amir measured his in room response and they had loads of bass and also could get by without subs assuming you are able to EQ out the room modes. The F328 was criticized the same way as the F228.

Then also just before that post someone mentioned a comment from Kevin Voecks regarding measuring deep bass in an anechoic chamber and how it is very hard to get right, especially with multiple woofers and the port contribution. It's a good read and shows that maybe we should have a different approach when measuring bass.

So 226BE would be better choice?
What about the differences between 226BE and 228BE (is this only bass extension)??

I've recently got a store display pair of F228Be. It was possibly the last pair available in Japan. Apparently they have altogether ceased selling Revel in Japan. Earlier I couldn't find any F206 or F208 and had given up, when I found this pair. It was over budget so I resisted for about a month, but finally gave in.

A question: I have a class A/B integrated amp capable of 240W a channel at 4ohm (120W@8ohm). Is it powerful enough to drive the speakers? Unfortunately I can't find any measurement of the amp. I don't listen to music too loudly but they say some headroom is important...

I use F228 with the 100W benchmark AHB2.

I did not notice any clipping at loud listening levels.

Amp plays cool by the way.

That's nice to hear.
The reason I asked was that I had read somewhere that with these speakers a single AHB2 was not satisfactory, but I couldn't find the post.
Searching more thoroughly, now I have found it:

I have been fascinated by comparisons between the Revel 228 Be and the open baffle designs (especially the Spatial Audio X5). Having just bought the F208's new, I was nearly convinced that the performance of Revel speakers were like 'drinking warm cocoa'. I assume this analogy aimed to suggest that they are not dynamic and even boring. That was the phrase used to compare them to the X5's and it did spring to mind when I brought them home and began playing them on a single Benchmark AHB2 amplifier.

That was before a friend suggested I run them on mono blocks. Well, I bought a second and now run them on two Benchmark AHB2 power amps in bridged mono. The difference is huge. Better attack, bass extension, imaging, sound stage, detail and tonality. The speakers definitely like power and boy do they reward that gift. I suspect this will be the same regarding the F208's successors, the 228 Be's.

You don't have the same problem?

I have never use monoblocks but maybe he use different dac. I am using with the benchmark dac2 hgc. This dac has a high output.

I used the Purifi amp with that kind of power and it had no trouble driving them.

I have 2x AHB2 as monoblocks driving the F228be in a large room. I find the max volume I'd want to drive them at from my SHD is about -18 dB maybe -12 dB (by the SHD display), listening at about 7m (the room is actually about 10m long). Normally, I'm listening to it around -23 to -30 dB. I should measure that SPL at the listening position, sorry I don't have that number.

As the monoblocks are about +6 dB over a single amp, I'd say a single amp would be sufficient. I do at times listen to wide dynamic range material, so I wanted the extra overhead.

The AHB2 also have a sensitivity switch on the back that needs to be set correctly for the pre-amp (or dac, etc.) that's driving it.

This is a new rig for me, so I'm still getting accustomed to it. I am very happy with the setup.

Thanks everyone.
So it seems my amp (Denon PMA-SX11) is powerful enough.
Actually I was thinking of getting one of those purifi amps and was wondering if the current 1ET400A is enough or I should wait till the newer, more powerful one comes out.

Don't know about the 228Be's but the Purifi Eval 1 amp drives my F208's to painfully loud but clean volume.

 

[fraa]

Ok, so now it looks like Dgob above is the outlier...
...I just ordered a VTV Purifi EVAL-1!

The F228Be is pretty easy to drive so there is more flexibility to get great sound out of them.

I have my Vtv purifi with kef r7, very good amp

So I have been enjoying my F228's for a few years now. I have them spread pretty widely to accommodate a 130" wide screen between. I used the room for mostly theater but some 2 channel. I want to move to an AT screen so I can situate the C426Be behind the screen and at the same height. My question is, how close to you think I can place the F228's to the wall? I'd like to put it all behind the screen for a clean look and to keep small hands away, just not sure what I can get away with for depth behind the screen.
Thanks.

 

[Laserjock]

Should be able to place fairly close. Front ported and all

I have the F228Be in piano black on order. It will be paired with my Yamaha A-S2200. Supply chain is a mess, so I'm not getting them until March to May of next year.

@amirm if only yours were in piano black, I would be sending you a message to buy them. I currently I have the NHT C4 holding me over, which by the way, would love to see you measure the NHT C4.

Edit: Originally, I was considering the F206, then changed my mind to the F208, then I said the heck with it, just splurge a little so ordered the F226, two weeks later, I said F it, I only live once, changed my order to the F228. Then the dealer tried to convince to me to double F it and to get the F328, which was in stock btw. Unfortunately, I couldn't double F it, F'in it once is as big as my balls can get unfortunately.

That's basically the process I went through, though I managed to not order and reorder, I just agonized over shopping carts. The F228be has great in-room response for me. You'll be (eventually) happy.
