What do you need to know?

I have the manual for the whole sixes series MK1 and 2. I can E-mail it if necessary. They are basically the same as your 611's with identical drivers except that they are in a taller cabinet and have a passive bass radiator.

I'd love to test them side by side with some 611's.
Unfortunately I haven't heard these speakers myself. I have heard that they are quite hard to find. They are certainly uncommon on Ebay.

N.B. As with the 609 and 611 there will undoubtedly be a difference in the upper-mid and treble between the 615 MK1 and MK2.

Regards,
Martin.

Too much bass? I doubt it!! I have NO bass. Well, I have some and it is very nice. It's just not enough. Anyway, you know how it is with the 611's. I am very jealous of you mate. I did consider buying some 615's myself but I thought ( before I got my 611's) that they may boom in my room. I hope you enjoy your new speakers as I cry here

I'm very surprised that you have beefier inductors in the 615's. They have the same drivers (except the passive radiator) and supposedly the same crossover point. I often think that with more bass my speakers would sound more even. I guess that's what is happening with the 615's. I'd love to see a picture of the crossover if you ever get one.

If the midrange sounds better to you then I would guess that you have bought the MK1 version? I say this because the Mk1 611's sounded a bit forward and Tannoy tried to correct this with the MK11 version. The MK11 has a toned down midrange but loses it's magic I think.

Remember that if your 615's are MK1 then you could always swap the Dual concentrics with your 611 MK11 to see which you prefer. Do not remove the treble horn from the mid or you could damage them!! Maybe it's not worth the risk.

I'm still confused I first heard the 611's in 92 and the bass was full and plentiful. This is why I didn't buy some 615's in the first place. Maybe with age the bass charecteristicas are changing? Perhaps the surrounds are hardening and raising the resonant frequency of the drivers?

Do the 615's completely satisfy you or is there still some bass missing somewhere?

I recommend replacing the cap on the tweeter. I used only 10 worth (including postage) of soniq caps and the difference was very noticable indeed. Everything just sounds smoother but with the same detail as before.

All the best,
Martin

hi martin please give me your email and i will send you a pic of the crossover.i have lost the email password i set up for this account so will contact you with another the 615 is warmer sweeter i do not think the mk2 was an improvement worth shouting about. i have just changed the diodes on the cyrus 2 pre section and it sounds smoother the more i listen to the 615;s the more i just will not part with them i love themthe bass is deeper honest you will enjoy there sound after a day as they sound totaly unique. the bass has a 17 watt resistor and a cap and the other drive unit an inductor, so i do not know which is the pasive bass unit i have tried to attach a pic but it says file too big thanks for the tweeter cap tweak

So does that mean that you got the Mk1 version?
One inductor on the bass is similar to the 611 but the 17 Watt resistor on the mid/bass is different. Interesting. I'd like to see the pic if possible. It's against forum policy to post email addresses in public but if you drop me a line via my Email button then I'll send let you have it

For the tweeter cap, Bear in mind that most decent polypropylene caps are physicaly much larger than the originals. I had to cut some plastic to stop the cap hitting the vertical bracing that runs top to bottom.

I'm glad to hear that you have a cyrus 2 now. Higher power handling is definitely good for these beasts!! I have loads of questions about replacing the diodes? (I guess you mean transistors). It's usually better to stay on topic in this forum so could you add the details to the 'Cyrus 1 amp later version' thread you posted in earlier. Please please please!! I need to do that to mine but lack the confidence.
I'd also be interested to hear how your CD4-SE is doing now.

Cheers,
Martin.

I know that we're supposed to stay on topic here but anyway (I tried),

I'm using my Cyrus 2 with a PSX so I'll replace the diodes there first. I'm not using the Phono section so changing the opamps for me is not necessary yet. What diodes did you use? Do you have a link to a supplier?

My CD4SE has been modified and I would love to test it against a modded CD63. It would be very interesting. For now I'll stick with the Cambridge since the warmth compliments the forward nature of my amp and speakers. I've tried other players lately but none has the X factor of the CD4. Let me know if you ever get around to modding your Cambridge. I'd be very interested to hear what you think of it against the marantz.

Back on topic, sorry:
Do you have the optional plinth for your 615's? There's a pair on Ebay at the moment. Given the height of the 615's it might be a good idea although it may change the bass characteristics.
