Adding Rear Speakers?

[HarryY]

I'm contemplating adding rear speakers in my living room.

I currently run open baffle speakers Bi-Amped in the front
with Two 15" woofers and one 5" full rance per side.

I was thinking of adding just two 5" full-range speakers, the same that the
front uses and also open baffle, on a separate amp for the rear channels.

Does anyone see any issues with this setup?

Thank you

Not as long as the drivers can match up peak SPL-wise down at/below the XO point/slope at low distortion and at ~the same polar response, i.e. if multiple rows of seats they will in theory be too far away, thus ideally needing waveguides [WG].

Since I use an electronic crossover (miniDSP) The rear speakers
will only be playing the same frequency range as the front.

I may use a second miniDSP for the delays etc for the Rears.

Is this for home cinema or music? For music I believe that would put things out of balance, using two stereo pairs require full range imo. For home cinema I see no problem as rear channels are over 80Hz anyway. Well three decades ago that was the case I have no idea anymore really what’s going on with all the new surround standards.

Yeah, in retrospect I should have asked, but being more cinema than music oriented..........: (

For stereo, things start getting complicated once away from the 'sweet spot', so ideally need a small one for ambiance using either digital effects or creating a diffuse rear sound-field.

This would be for music mostly.

Same speakers as the front but turned down quite far.

My earliest [4.1] HTs were like this, but wasn't until I 'borrowed' a Sansui? Quadraphonic receiver did it sound 'right' [at the time], though better still when later switched to a proper rear channel stereo adjustable delay.

Regardless, good luck with it and please let us know how it turns out. 🙂

I have a spare miniDSP unit that I plan to use for adding in the proper delay.



Thanks all for the help.

with appropriate amp, the old "Dyna Quad" setup can extract an enormous sense of ambiance from some recordings. (Sinatra's "Only For The Lonely" for one example)
