Hi Bill etal. On the omnitop 12 and other horn loaded designs, you specify a larger diameter phase plug for a lower frequency crossover. Can you explain why this is? What happens with a wrong sized phase plug?

Thx

Similar question. Building a J12 for a friend primarily for bass guitar, but trying to make it more flexible and able to use it as a PA also. In this case should i use the “PA top with passthru”? He has a hartke TX300 which uses +1-1 Should i keep it simple, ie bass only?
Thx

“The recommended home theater drivers are Dayton (www.parts-express.com) RSS 390HO for the ported cab, RSS 390HF for the sealed. If these aren’t available the ideal driver specs for ported are Fs 24Hz, Qts 0.35, Vas 100L, minimum xmax 12mm, impedance 4 ohms. +/-10%”

Do i have old plans?

Hello Bill etal. The recommended DA rs390ho (ported) is unavailable until june. Can i use one of the pro sound drivers with the longer HT ports to get similar response?

Thanks

Great, thanks Bill. Do i need to upgrade my beloved autotuba to keep up with the SLA?

So the sla pro with 2 mids would be louder than the sla with 6?

Dont be talkin shit about my autotuba!!

Seems like an rp600 x 2. Twice the drivers. Not the best choice i gather?

I got sucked into the klipsch rp600m frenzy and i like them ok as HT/stereo with my autotuba. Good efficiency & dynamics. To take it up a notch would you recommend the SLA pro 2 mid, the SLA 4 mid or SLA 6 mid? Or maybe something else?
Thx

Thanks Bill. Looking for drivers, PE has only the shielded version of the 4”, i assume this is fine?
Also,since xmax is 1.5mm, do i need a high pass at 80hz or so to protect the 4 inchers? (Thinking sub of course)

Thx

Dayton offers a 4” coax speaker. Can this be used for an SLA application?

Interesting, so is there a rule of thumb for off-centering such as the 2/5-3/5 rule often quoted for DMLs?
And do wedge or trapezoid shaped cabs work better to avoid internal resonances?

Pulling from previous post: I asked if the Simplexx 10 cabinet could have a smaller front baffle so long as cabinet volume and port size/shape are maintained. Bill said yes. Follow up…am i losing anything by doing this? I’m sure Bill had good reason for sizing the baffle as he did and offsetting the...

Question about the S10 cabinet, if the volume and ports are maintained per plans, can the baffle panel be smaller than in the plans? Thx.

Ah ok. Does that arrangement sound as good as the wood horns with compression driver in the DR, Omni,Jack? I realize they will get plenty loud for home music/home theater, but which has the best sound? Thx
