I have a custom system so I m putting 2 7.1 on real left and 2 on rear right and 2 7.2 for centre and 2 beolab9 for front left right - I need 3 x 50 cm 8 pin two males to on female and 2 long male male 8 pin 1 shorter one and I have a fac converter to 5.1 from amazon therefore I need 5 rca ( without sub) mono to stereo rca- 8 pin that needs to be triggered by a 5 v usb

[@irelandgp]

So I can either dyi myself the cables either do you have 5 x 2 rca male to 8 pin + usb 5v ? I did it myself in the past but there is noise - however I ll be using magnets and phone charger or tv source for usb to see if any difference …can you offer something better ? I could draw a diagram if it s hard to follow…

Good video Steve. I cant wait to try the credit card trick to get those frets off. Couple more tips: When you have the frets off, spray them with a textile cleaner, clean them in the shower and let dry. Be gentle, this might be the thinnest material ever seen on a speaker fret. Its amazing how much c..p is in them after 30 years. Seriously consider getting the capacitors replaced in the crossovers and amps. They dry out and their values change after 30 years. Kits are available. These are worth spending a little money on !

[@soundsheavenly]

Thanks, these are great suggestions! I'm not a repairer, so I didn't look at opening the speaker for the video, but I agree this is a worthy upgrade for those who are able to do it.

[@bfb1962]

Hi, Steve. Saw this video about four months ago, and just thought about it yesterday. So just now, I finished modifying my right Beolab Penta MK3 speaker. Turned the speaker panel. Both tweeters are now facing inwards. What a difference that made! Sound is so much better now! Thanks again for the tip 👍🏻

[@soundsheavenly]

Thanks Bo, glad to hear that the tip was helpful and that you are enjoying these great speakers!

[@wimjoos9125]

@@soundsheavenly : Owning a set of Penta's myself, turning one panel around so you get a mirrored pair is a good upgrade. But you also have to change the mid range speakers, because they are NOT identical! one unit has an other type number and is mounted on a specific location.

[@soundsheavenly]

Yes, but the two inner midrange speakers match and the two outer midrange speakers match, so they are still correct when the panel is rotated

[@wimjoos9125]

@@soundsheavenly , there is one different mid-range unit on each side ( the upper one of the two middle ones). So turning the panel around will put the other midrange on one side lower than on the other. Maybe this is different on certain production runs. My Penta's also do not have T10 torx, but only Philips screws.

Thanks, sounds like there is a variation on some speakers

Hello Steve, I've enjoyed all your videos. I'm using a pair of Beolab Penta speakers connected to a Yamaha receiver using the RCA phono input on the speakers. Works GREAT! I'd like to make an external circuit that I could manually use the display on the speakers via 8 pin DIN connector. Would this be practical? I would need the pin outs & signal/voltages of the cable.

Steve, I remember trying the reversed tweeters trick on clients sets back in the '90s. It made good sense to me. And since I was selling new systems, they always used PowerLink anyways. The 50 kilo blocks make a great acoustical enhancement I'm sure, however a bit difficult to sell the idea to spousal units at the time...

[@soundsheavenly]

My good lady wife still hasn't spotted the concrete block (I guess I will be in trouble if she watches this video!)

[@nicolasborgiani5399]

Thank you for your time, I will try this and write you again, I'm very happy with this speakers, I used to play music with a pair of klipsch rf62ii and still can't find something bad in this penta (6633 mk 3 I suppose) compared to klipsch, they are beautiful, aspect and sound. Thank you.

[@micronian]

I first got introduced to B&O back in 1999 when I started working for a B&O installer in the NYC metro area. My boss used to always recommend a 1 inch thick slate tile underneath the Penta when it was installed on a rug covered floor. And for MK1 Penta he always used this adapter that would give the MK1 Penta a female Powerlink connector. He had a case full of them back then, they are probably worth their weight in gold these days.

[@soundsheavenly]

That is a good suggestion about the slate tile for weight. Yes, those adapters are out of production now, so well worth buying if you can find any pre-owned adapters.

Love my penta's! Was able to haggle a pair down to 150€. Beovox tho, because i don't need them to be any taller than they already are haha. Currently running them on a Cayin A50-T amp. Replaced the foam surrounds, replaced all the capacitors on the MASSIVE crossovers, and now i'm restoring the tweeters because few people seem to be aware of the fact that these are ferrofluid tweeters. That fluid didn't look so good anymore after 36 years! And taking those suckers apart was no easy feat without any guides on KZbin...

[@thor7564]

Turning the mid/tweeter unit 180 degrees did nothing for me back then, and considering B&Os deep knowledge of speaker design and testing, it's not likely they made such an obvious mistake if it was degrading the sound. But: I might have been attending too many concerts to notice any possible gain from mirroring the Penta 😜 All other tips are bang on. Penta is by design exactly the opposite of what B&O wanted to achieve with the acoustic lens: Penta is made for a narrow sweet spot, but that spot is indeed sweet. I had them toed a bit further inwards from your position. If you are more about getting the best sound from Penta than keeping it all B&O: get the Beovox Penta (or disconnect the Beolab amp) and have an upper class 2x200w (or upwards) power amp driving them.

[@soundsheavenly]

Thanks. I wouldn't say B&O made a mistake in setting both speakers the same way around, they made the speakers to give the best sound for most situations, without the user needing to do anything special for the setup. This gives scope for owners to gain some extra improvement by tailoring the speakers to their situation.

[@martinjandijkstra3205]

In my old beolabs one of the capacitors in the power supply part was broke. I replaced all caps. I understand this video is about relatively simple hacks but a good recap may be essential.

[@MultiIfran]

great info thank you .. but isn't it better to place the medium inside and the tweeters outside?

[@soundsheavenly]

Good suggestion, this can vary from one room to another. Personally, I prefer having the tweeters facing inwards, as this tames the slightly ‘shouty’ effect the Pentas can have in some spaces if you get too much of the midrange driver sound. If you get a chance to try both options on your speakers, please let me know what works best for your ears and room!

[@Schweini_1983]

I had my crossovers rebuilt and replaced the mids and tweeters. The tweeters were blown and the crossovers had popped caps. They sound amazing now. But I don't believe for a second that turning the mids 180 degrees will make any difference whatsoever. I would love to get icepower amps

[@soundsheavenly]

They are great speakers, especially when restored. If you aren't convinced about turning the tweeter panels, play sound music and walk from side to side while listening - you should hear more midrange on the side with the four mid cones and more high treble on the side with the tweeter. You can get better control of the sound by matching the panels as a mirror image of each other and turning the speakers inwards or outwards until the sound is to your liking.

I can't fault your speakers or your choice of music, maybe you need better house guests? ;-)

[@Dreez76]

I've always dreamed of having these speakers. A dear friend of mine which turned me into the musiclover i am today, introduced me to these speakers while playing Mike Oldfield - Voyager CD . I was utterly blown away and started building my own speakers from that day. Sadly he passed away in cancer, but his impression still lingers, and i still want these speakers. Problem is that i have no interest in the Beolab stereo, i have a Yamaha A-S1100 which powers my current speakers, and connecting Beolab Penta's to regular amps is a bitch , especially if you want the display working.

[@soundsheavenly]

Yes you can use these great speakers with any amplifier but the displays will not light unless you use a B&O music system. Please ask at soundsheavenly.com if you need any help with connections

Would you recommend lifting the speakers from an oak wooden floor resting on about 40 cm of massive reinforced concrete, or would it be overkill? I'm reasoning that just an isolating rubber mat under the speakers will be enough for me. My floor is more than enough for a heavy gun safe... Also, does these tweaks apply to the passive Beovox Penta's as well?

[@soundsheavenly]

Hi, the simple answer is try it and see if it helps with the sound in your room. Both passive and active speakers produce the same sound, so the same issues apply to both.

[@magnusfranzonuvebrant9519]

Hello Steve! First of all, thank you for the excellent cables that now connect our BV 7 55 (with Beolab 7-6) to a pair of Beolab 6000. I am thinking of getting a pair of 8000, to use as well. I gather the Penta would be a bit of overkill, and rather missmatched with the 6000!?! Thank you again, and all the BEST! Magnus in Sweden.

[@soundsheavenly]

Thanks for your purchase and for your kind words! My view is that Pentas would never be overkill, their sound is so much better than Beolab 6000 even at low volumes that they are absolutely worth adding. You can adjust the output level via the switch on the front panel to reduce their level, then they won't over power the 6000s.

[@beitie]

Nice video! My Mk I Penta's are kind of a mixed bag. When I bought them, they were very worn out, missing some parts, lots of dust caps pushed in, and the ferrite core materials around the crossovers were shattered into 1,000's of pieces. So I had quite a bit of work ahead of me. I had the rotted foam replaced, bought a used set of Mk III woofers, and crossovers. Had all the capacitors replaced, and bought the amp kit from Martin on Beoworld. So mine are still Mk I's but with Mk III crossovers. Running off the dreaded speakerlinks to my Beocenter 9000. Eventually I'd really like to get a Beocenter 9500, and Beolab 5's, but I'm pretty happy with it all for now. I know in this video you say to ditch the speaker link, I'm not sure what my best course of action would be there. I could consider trying the Pre Amp output of the Beocenter 9000 to the Phono plug (RCA) input of the Penta.

[@soundsheavenly]

Thanks! Yes, you should get better sound via the pre-amp outputs of the 9000 to the RCA inputs of the Penta, if you buy the cables in my store then I can help with an option that keeps the Speakerlink cables to use the display, a small change is needed to the wiring for this. Please get in touch at soundsheavenly.comk for more details.

[@mogensranneries7517]

Great idea to turn the speakers symmetrical. BUT - I remember from my tech. class (back in the 70'ties) that the tweeters should be right most at the right speaker and left on the left speaker, in orders to get the widest stereo perspective. But what do I know - physics might have changed since then...

[@soundsheavenly]

Thanks, that is an interesting point...my view is that either can work, it varies depending on the room acoustics and whether the speakers are "toe out" for the widest sound stage, or "toe in" for the most accurate stereo image - but that is getting a bit beyond the ability of my ears to hear the differences!

[@112Ullerup]

I've got me a pair of Penta (6601) for my Beocenter 8300. I was not aware of the different connections. I've already have changes the foam on the midrange speakers (foam-rot) and of course turned the section around (that one was obvious to a HiFi man :) ). I've been searching for the mentioned speaker-link cables, but couldn't find any. Now you are saying its not the best way, and I'm totally in on that, but how do I connect my speakers? DIN to phono cables an an extra with the two extra pins from the DIN-speaker socket?

[@andrewberridge4630]

I love my Pentas. I also own a pair of Beolab 5's. The 5's blow them away of course, but the Pentas do sound sweeter and have fantastic stereo imaging. There are other upgrades you can do - e.g. replace the on board op-amps with Burr-Brown ones, for a smoother sound; replace the capacitors in the crossovers with high end ones, but these are for the technically minded. Also, I've had a number of the amplifier/power supplies fail - I got a bit fed up replacing/repairing them, as the faults were different every time! In the end I used a generic Class D amplifier from eBay and wired it directly to the speakers. They sound better than ever before. I also recommend a separate subwoofer if you need deep, powerful bass.

[@soundsheavenly]

Thanks, that is great advice! I wanted to just cover the easier upgrades in the video, but I’m seriously considering some of the improvements that you suggested

Hi Steve, I found a gorgeous set of M1's that had the midranges refoamed.

I initially did intoeing which improved the sound and now I also changed the twiter side with further improvement.

Very helpful tips by the way.

[@soundsheavenly]

Thanks, glad the video was helpful! These are great speakers

[@beopaul]

Hey Steve, great video. When you had the middle panels off for flipping, did you notice if they can be easily unplugged as a unit? Thinking if my midranges need refoaming, perhaps I could pull these out instead of taking the whole speakers in. Thoughts? (they've been sitting in storage a couple years but have been in otherwise regular use since around 1991). And you're so right about proper Powerlink cables. I want a few years with the 4-pin speaker cables from my BeoCenter 9500 before switching over, and was amazed how much better they sounded.

[@soundsheavenly]

Thanks. Sorry I can't recall if the midrange panel can be unplugged or not. Yes, good Powerlink cables are certainly the best way to connect the speakers, the sound is far better than via the old Speakerlink wires!

[@tniedermeyer]

I just acquired a pair of Mark 2s, am very pleased with them. The surrounds look like new and I switched their positions to put the tweeters on the inside. I use standard phono cables to drive them because I don't have a B&O system. Do you have any criticism of driving them this way? Thanks for the tips!

Instead of concrete blocks I put subwoofer isolation pads under my Pentas (on a hollow wooden floor). Would that have (about) the same effect? A big pro is that it is a bit easier to move the speakers around in order to find my preferred listening position(s)! I also just flipped the midrange speaker section, curious to find out if I can spot the difference!

[@soundsheavenly]

That is an interesting idea - I haven't tried these isolation pads but they should help to reduce bass vibrations from the speakers reaching the floor. The concrete blocks work by adding mass to stop the floor moving, so a slightly different approach.

[@Johnathan_Waters]

I just got my first set of BeoVOX Penta's (literally yesterday), and I did the "flip" of the midrange assembly, and I am happy to report that it most certainly makes a difference! Thank you for posting this. Now I just need to order up a set of new foam surrounds for the midrange (mine have gone all spotted and are tearing). Do you have any opinions on using rubber or foam surrounds here??

[@soundsheavenly]

Hi, glad the video was helpful! I would always fit the same material in the speaker surrounds as the original design, as changing this will change the characteristics of the speakers. I have used GoodHiFi for B&O speaker surrounds in the past, I think they are based in Netherlands and sell on eBay and via their website.

[@Trev9]

How do I tell the difference between a mk2 and a mk3?

[@soundsheavenly]

Mk.3 Beolab Pentas have a green display, while mk.2 have a yellow display. Also the 3rd digit of the type number is different. In all other ways including sound quality, they are identical.

[@raz0r2k]

Thanks Steve, I enjoyed the video greatly. I've got my own pair of Penta MK3s that I've been refurbishing. I don't know what it is about these speakers, but I'm sure I'll never part with them. I've got mine on a wooden floor (parquet I think). Would the concrete blocks help with sound quality on wooden floor too, or only carpet? And I saw another viewer comment about slate tiles - would they do a similar job as the concrete blocks? Thanks again. I really enjoy your content, and hope you'll make more on the Pentas.

[@soundsheavenly]

Thanks, glad my video was helpful! The tiles or blocks help to add mass to give a solid base for the speakers. If the floor construction is concrete then you may not need this, but for any kind of suspended floor or where the floor sounds "hollow" when you stamp your foot hard then adding either type of solid base can improve the sound.

[@contemporiser]

I re-foamed mine a couple of years ago so have that sorted, but was interested to hear about Speakerlink being not great - I knew it attenuated the signal and then amplified it again, but hadn't really given that much thought. Would it be best to use the line level inputs to them then? I have a BeoSystem 5500 so I'm not sure of what the best way to connect them would be. And it would also be a shame to not have the displays working - I've always thought they were fantastic!

Why don't people use rubber to replace the foam? That should hold way longer! Is there a difference in sound?

[@leeshepherd6512]

The rubber has a different compliance which would/should effect the sound.

@@leeshepherd6512 Interesting, thanks for your reply! :)

[@soundsheavenly]

@@Jondedy Thanks Lee, you beat me to it! Foam is the best option for sound, if you keep the speakers in a dry, smoke-free environment then you should get several decades between each re-foam.

[@Jondedy]

@@soundsheavenly Awesome, thank you very much! Foam it is than! Though if I buy a pair now, i'd go for a pair that's already refoamed. That saves a lot of time :)

Hi Steve, can I ask you something about teh penta speakers? About the midrages, only sound 2 speaker of the 4 that have each tower, in both towers are the same. I have connected with line in only, never connected to other system o B&o. Very grateful. Bye.

[@soundsheavenly]

Hi Nicolas, all 4 of the midrange speaker drivers should always give sound, otherwise you have a fault in the speaker somewhere. You can test these using a cardboard (paper kitchen roll) tube to let you put your ear to just one speaker driver at once while the music is playing

[@nicolasborgiani5399]

Thank you, I take out the entire panel and realise that if you disconnect 1 of 2 center midrange the sound of all 4 midrange goes off, then check the sound in the 2 midrange (the uppest and downest) and sounds like surround can be? The sound and power is not the same than the 2 midrange of the middle, excuse my poor English, I'm from Uruguay.

[@soundsheavenly]

Please don’t worry, the outer and inner midrange speakers are meant to give different sounds, this is how the speakers are designed.

[@pertangelauridsen280]

Hi Steve, I don’t know if you want to make any recommendations on this but I have a pair of Beolab Pentas mk2. From a sound quality point of view do you think it is it better to use or bypass the Beolab amp? I am using a Denon AVC-X3700 amp in pre-amp mode (and your cables) at present. One of the speakers goes into Autolimit mode when turning on and needs to warm up for 10 minutes or so before working. Bypassing the amp would fix that problem as well I expect.

[@soundsheavenly]

Hi, for best results, please always connect to the receiver pre-out sockets and use the amp in the base of the Pentas. If the speaker has a fault I recommend asking your local B&O dealer to recommend a repair agent (sorry I don't know about repairs) as you won't get the best sound quality until this is resolved.

Hi Steve. I found some MK3 models online and was quite interested to get them. My setup is currently two Rega players and a regular stereo/cinema amp (to be changed eventually) Do you think they would still be a good fit for the main channels? And as for foam rot, is it the entire woofer that needs to be changed? Thank you!

[@soundsheavenly]

These are great speakers, they should work well with any amp - please get in touch at soundsheavenly.com with the model number of your amp if you need help connecting them. Only the foam surround of the midrange speakers is affected by foam rot, whilst I can't advise on this, if you search for "Good Hifi" online, they have the parts and advice for replacing these items.

[@NiGHTSaturn]

@@soundsheavenly Thank you so much for the advice. I just got them, can’t wait to install them properly. I noticed also that you have rj45/powerlink cables. Does that mean if for example I own a Beosound Moment that the display may work with it? I will definitely order some accessories from you!

[@SuperJuul81]

Great video. In future videos, it would be interesting to hear about connection options for these speakers. Obviously you can connect them to a stereo, like a BeoMaster 7000, and use a remote control through that system. But can you eg. connect directly via jack/phono via a Crome Cast/Apple Airport Express? How about display and control of volume/base/balance etc. What about auto on/off (I believe they do that). Them having their own amplifier and with today’s streaming, what’s the most simple way to connect these, while still retaining ease of operating them and keeping the good sound quality. Maybe a “control unit” stereo system is best?

[@soundsheavenly]

Thanks! Yes, I will cover the connections in detail in a future video. In the meantime, please feel free to get in touch at soundsheavenly.com with any connection questions. You can easily use the speakers with a device like a Chromecast Audio or Airport Express, the speakers will turn o n automatically when the music plays but the display won't work, you just need this cable: soundsheavenly.com/line-in-connection/77-241-minijack-to-beolab-line-in-using-phono-rca-sockets-one-cable-for-two-speakers.html#/2-length-1m

Looking at getting a set of Pentas there too. And would like the simplest setup. So very keen to hear about functionality and control. Can’t you e.g. use a remote to control the volume? Thank you for the link :-)

[@soundsheavenly]

@@SuperJuul81 The speakers won't respond to a remote control, only a B&O music system will do this. If you wish to use a remote, please add a B&O music system and connect the speakers to this.

[@SuperJuul81]

@@soundsheavenly Okay, sure :-) But then I don’t understand how you control the volume. The audio out on a streaming device like Airport express gives a signal “volume” which can be adjusted like when plugging in headphones. But how does the amplifiers in the speakers know how much to amplify? I’m normally really in to this, but this I don’t understand. I have a Beloit 12 in my kitchen. It’s hooked up to an Airplay 2 unit for Apple airplay multi room. It’s normally set on full volume on the output from the airport unit, and then the volume is adjusted on the Beloit for minimum distortion. Same thing on my Beosystem 7000. But how does that work if connected directly to the Pentas. Does the amplifier automatically read the input level of the jack-phono? This puzzles me. I’m so sorry for asking this many questions. Great great KZbin channel you have. I’ll make sure to order from you when needed and link to you channel.

[@soundsheavenly]

@@SuperJuul81 Thanks, glad you like my channel! The speakers have a fixed volume gain, the phone will set the volume level when you play through a wireless device to the speakers (just as if would if you had headphone connected to the phone).

No problem! There are many thousands of amplifier models to choose from, so probably best if I don't try to recommend a specific model. However, the good news is that you can use just about any amplifier with these speakers. Please feel free to get in touch via the contact page at soundsheavenly.com to let me know which model of amp you choose and which version of Pentas you have (the 4 digit type number on a sticker under the speakers will confirm this), I can then help you to get everything connected!

Hi Steve. I have the Beolab Penta Active loudspeakers paired with the old Beomaster 5500 system. The sound system has not been used for a couple of years and when I tried to turn it on for the first there was "no contact". I've just had the amplifier fixed by a repair technician and they discovered that there was a broken fuse in the amplifier. However, when I came home to try the sound system, it did not work. It seems that the amplifier Beomaster system works, but there is no contact with the speakers (no red light at the bottom of the speakers like yours). My question is; Is it possible that there is a broken fuse inside the speakers or is it simply a setting I need to try? //Kristian

[@soundsheavenly]

Hi Kristian, if the speakers don’t show a red light when connected to the mains power, then the speakers are faulty. Sorry I don’t know about repairs (I just make cables), but your local B&O store should be able to recommend a repair agent in your area.

Good question! Unfortunately, Beomaster 3300 only has 3 pin speaker sockets for operating remote speaker link kits via MCL, so it can't light the Penta displays (this needs the later 4 pin sockets as fitted to the Beomaster 3500)

Thanks for your reply Steve. My Penta 3s are awesome. is it possible to bypass the amps to use them as passive speakers, driven from a non -B&O power amp? is the Line -In the same spec as traditional preamplifiers?

[@soundsheavenly]

The simple answer is "DON'T DO IT!" Everything that makes the Beolab Pentas great starts in the power amps. You can remove the amps from the base of the speakers if one day they fail, then you are left with passive Beovox Pentas that won't sound as good. Until then, keep the amp in place as it is a superb power amplifier, designed to drive these speakers to their full potential. They won't sound as good without it.

[@Trev9]

@@soundsheavenly Thanks Steve. What I meant is, is the speaker there for that purpose? Can it be connected to a none- B&O power amp via this input?
