Re: Rise of the Eighteens

Sonnie. I don't want you to worry too much if you end up with a system that does not exactly give you 4 or 8 ohm. There won't be a huge difference between different loads (as opposed to what you might think) The EP 2500 power at 4 ohm is ~ power at 8 ohm.

Re: Rise of the Eighteens

If I bridge it 4 ohms... I get about 1950 watts. At 8 ohms bridged... it is about 1330 watts, still good power, just not taking advantage of all of its power.

Re: Rise of the Eighteens

Figure another 8-9dB from teh 15s, plus roomgain, and you're looking at serious structural damage to you house, Sonnie. You are aware you can reach reference outdoors with that setup? Pretty over the top!

Is it based on specs or measured? The TA-2400 Amp will have quite similar power at 8, 4 or 2 ohm load....

That is tested power.

What is the TA-2400?

Looks good. You could even increase the enclosure size by a few more ft each, decrease the vent length and raise the port resonance above 200hz. Splitting hairs...

Re: Rise of the Eighteens

This is actually for two drivers in one enclosure.

I am having a brain lapse... Is that port length for both ports combined or each port?

Each. I knew it was 2 in one. I was thinking you could go to around 46-48ft total for the 2 and reduce the port length a bit. It's gonna be a Haus regardless. (I just edited my response right into your post on accident. Oops. Thought I hit the quote button.)
