New center build, opinions please !!

[matsj]

I´m going to build a new center speaker with a 1,5" horn and 2 x 10" speakers. Am i getting trouble with a laying MTM ? Or should i mount the horn above the 10" like this Jbl center: JBL SYNTHESIS - Product Details

Crossover freq is 750hz.

MTM if you don't have constrains dimensions

I'd be worried about horizontal lobing and try to mount the tweeter above the woofers.

How many people will be listening to this?

Agree.. There are other threads dealing with those issues among other problems:

I would watch the Center to center distance but at 750Hz you certainly have more room. How wide is your horn?? Clasic MTM is distance equals 1/2 wavelength at crossovers. I use the Array 880 as the center in my HT set-up, even though it's an MTM it sounds very smooth off axis. You can't hear any obvious lobing issues. It also has the horn vertical though and that helps minimze the C to C distance. The woofers are twin 8"s.

My horn is 520 mm wide.

Well with a 20" horn and another 10" at the least for C to C I would definately drop them under the horn. Wavelength is only 18" ay 750 hz. You would want 9" C to C you are not going to make that with the horn in the center. What are you using the 9800 horn clone?

A Tad Th-4003 with 2 Tad tl-1102. I have the 9800 clone in another setup.
