Other choices include the RCF 4Pro and a few others in the same general shape as what you had. On top of all that, we Americans usually go a little heavy on the low end and have the HF response stepped down a bit. Mounting Type4-Bolt Exit Diameter1. The Coherent Wave phasing plug structure has four equal length passages to provide in-phase summation of diaphragm output at the 1.
The Model J is a 1. You’ll save a little weight on an already heavy cabinet. I don’t want to start a crossover topology war here on the top end.
Should I modify my SR4732A’a or leave them stock?
I’m just not crazy about the ‘s only doing 1. Is it worth it? Jvl voltages above the heat level the driver can take may be an excursion problem, and they may not. High temperature voice coil former materials and adhesives enable the J to handle high power levels over extended periods of time. Quality is important as I would be using the subs with my Nexo GeoS8 system.

When I decide to resell, I can offer the cabs as is, or offer them stock with a new diaphram. An amplifier capable of 67 volts at 8 ohms is equal to Tim Weaver Senior Mar 24, Gary Weller Sophomore Mar 24, Silas, I’ve got the pdf’s from nbl the a and the a. I thought you were bang on until you started talking about impedance.
That is a question I will have to answer once I have a bit more experimentation under my belt. You have few options for powered dual 18″ subs. What have you looked at so far? What exactly are your needs for “keeping up” – are you intending to have one box per side?
All tolerances are held to the jvl high levels traditionally associated with JBL designs.
How big of an amp would I need safely for the ‘s considering they’re 16 ohms? That’s still not enough. Maybe not to remove the components, but at jbll for me to decipher what’s going ubl there. January 24, I recently got a steal of a deal on a pair of jbl SRA’s. So yes, a watt amp at 16 ohm would suffice.
You have a lot of options in powered single 18″ subs from all of the above mentioned vendors, plus some interesting horn loaded ones from Danley that can be ordered in a powered configuration.
Also in the marketplace thread, I mentioned that you should pretty easily be able to delete the low-pass on thewhich is probably just two components, an inductor and a capacitor. Everywhere Threads This forum This thread. Thread starter Gary Weller Start date Mar 24, Am I crazy for thinking this, should I just repair the blown and call it a day?
The polar curves of the exhibit soft-edge pattern charac- teristics, due to the gradual drop-off of level with increasing off-axis angle. I am wanting to possibly go to powered mains but I am unsure what can keep up to the JBLs. The XTi is capable of watts at 4 ohms. Like I said, it ain’t right, but it’ll work.
By the mbl power compression kicks in on the woofs and our affinity for a laid back HF, I still say that watts will do the job. Those horns are really efficient. It may take watts to get 10k up to our reference level, but at what listening position? That was probably 20 years ago. It may take watts to get 10k up to reference for that guy 45 degrees off axis.
If the driver is specified at 8 ohms there is probably a reason for it.
