[hardcore_gamer99]

I have for now dali opticon 2 mk2 fronts and svs pb 2000 pro with denon x4800h. Will dali opticon vokal be enough for room 12.7x10.7x10 room. I can also buy dali rubicon vokal but is costing me 1.90 lakhs rupees while opticon vokal costing me only 80000 rupees. Will be massive difference between the two in dialogue clarity? For 1.90 lakhs i can buy both dali opticon vokal plus dali opticon 2 mk2 1 more pair to use as surround left right. Plz suggest thank you

I believe Everett is suggest you consider using an Option 2 for center too. So that your left, right and center speakers are identical. This is typically ideal.

Generally speaking, center speakers are a form-factor compromise. It's a sonically worse speaker in order to fit it under/above a TV. But if you can fit another speaker identical to your L/R, it typically will sound better. Again, very generally, but typically bookshelf or tower speakers sound better than center speakers and are free from some issues that most horisontal center speakers have.

You're better off with a vertical 2 way than an MTM center due to loobing. Ideally if you have to comprise a center, a 3 way is your best bet if you can't can't do a vertical speaker.

MTM is mid woofer - tweeter - mid woofer, and in a horizontal orientation it has a very narrow sweet spot and has lobing

will audessey not help?

Not really as it's a design issue. There are MTM centers that do measure well, but not many, that's why I suggested another bookshelf from Dali if you can swing it.

If not I'd rather see something like a KEF coaxial center for a 3 way if the Dali three way is out of reach. They have excellent measurements and their coaxial design will provide good off axis sound.

dali rubicon vokal and rubikore cinema both are 2+1/2 way not work?

I think either will work with the hybrid tweeter system.

This was already discussed in another thread. Best option is to have the same 3 speakers up front but you need to have the space below the TV to fit the Opticon 2 vertically. If you lay it horizontally then it will have the same lobing issues as a 2-way centre speakers. They may also not sell the Opticon 2 as a single speaker (pairs only).

To match the timbre across the front, get one of the Dali centre speakers. The hybrid tweeter is also used in some of Dali's higher end speakers and it is supposed to improve horizontal dispersion. Tweeters begin to "beam" at higher frequencies. That is to say, the horizontal dispersion narrows as the frequency increases, so the response changes off axis. The hybrid tweeter is supposed help correct that problem. I have not seen measurements to confirm this but they have been using the hybrid design for quite a while.

i want to go with dali rubicon vokal is it good? placed horizontally and blend well with opticon 2? it is costing me 2300 usd. or i get opticon vokal for 1000 usd and i can buy 1 more pair of opticon 2 mk2 that would complete my 5.1

The use of two tweeters is meant to increase dispersion. When I said hybrid I was referring to using two of them, not that one or the other is actually hybrid, just the setup. The Cinema will give you more headroom, but I wouldn't spend $3k on it if it were me. I think you'll be happy with the Rubicon Vokal MK2.

If you look at the original Oberon Vokal (without the dual tweeter) in this review you can see the narrowing.

DALI Oberon Vokal Center Speaker Review

This is a review, listening tests, EQ and detailed measurements of the DALI Oberon Vokal center home theater speaker. It is on kind loan from the member and is on sale for $US 480. The word "cute" comes to mind given the rather compact size and look of the Oberon Vokal. What is unusual is a...
