Hey Chris, what does SS say about your question?
No response, yet. Must be busy making speakers.

Re: RL-P15's, Choose D2 Ohm, or D4 Ohm?

I asked the same thing. Mike basically said 'it depends'...

His answer in full:

Quote:
In so far as voicecoil configuration, it seems that most home theater users who build a box similar to yours (260l, 14Hz tune) end up going with the dual 2ohm configuration, however if you have a power supply that work better with the dual 4 ohm configuration, I would suggest thet the different configuration will by no means 'make or break' your system.

Re: RL-P15's, Choose D2 Ohm, or D4 Ohm?

I checked for a response from SS among my spam mail, and there, tucked in-between 50 offers of methods to enlarge my "unit" (how did they know?) was the response from Mike:
Quote:
There isn't going to be a whole lot of response variance between the
different coil configurations. The decision between which coil
configuration to purchase should rest primarily on which amplifier (if any)
you already own or have in mind, so that you can match the nominal impedance
of the driver to the amplifier for the most appropriate power feed. For the
RL-p15, you should be aiming for between 750 - 1000 watts RMS for optimal
performance.
From that, I can say that I am on the right track with my Crown amp.

I just got my 15's in, and SHITE!! These are monsters! As soon as I clear a little space in my garage, construction begins!

Quick update for pricing: Another Sonotube supplier in Dallas, White Cap Construction (they are located nationwide) sells the 12' x 20" for $75.86. That's a good deal.

Are you still going with 260 liters tuned to 14 hz?

Sorry about the seriously tardy response, but yes, that was still the plan. As a matter of fact, I have to begin this project soon, as I have just recently sold my Polk sub, and need to replace it. Why did you ask, got a better idea?

Thanks,
Chris

I was just curoius what you decided on. Post some build pics if you can.
