Anyone used this yet? sims pretty good...

Upping an old topic.

What do think how would sound 3-way floorstander TMWWW with all Seas, tweeter (27???), MCA15RCY and 3x L16RNX 1 // 2 (2 x in series and they parallel with one).

Unless you are into some fancy filtering that you have not shown or I have misunderstood your question -
Parallelling 2 serial connected woofers with a single one, means that the single chap will have to work twice as hard as the two serial connected ones. So instead of increasing dynamic range over two woofers, you actually have reduced it.

Do you think that dynamic range (or other parameters) reduces if you put one more woofer, you gain more boost from floor (longer array) and get easier load (5,3 ohm) versus two paralleled woofers (4 ohms).

Hi,

No. You are simply wasting the capabilities of the series woofers,
and the dynamic range remains near identical, fairly pointless.
4 of them makes far more sense, choice of 4 ohms or 8ohms.

Its a bass unit only, TBH H1520-08 U16RCY/P looks a far better
bet for 2.5 way, which is far better use of small bass/mids.

rgds, sreten.

3 identical woofers should be in parallel ideally, series if you have to.

That's true that 2 series woofers can't give their best (maximum pressure). But still they give acoustical benefit more than 1 or 2 woofers and play more like point source compared to 4 woofers because of power tapering (might be useful if xo is highish for 3-way). Also takes 25% less volume than 4 woofers.

This is offtopic in this, lets continue woofer array duscussion somewhere else.

How do L16rNX sims for woofer? 8-12 l reflex?

The SEAS H1520-08 U16RCY/P is a great bass performer. Actually it's a bit better bass performer than the ScanSpeak 15W series in my opinion. That opinion is based on personal experience and not on theoretical calculations, but on a subjectively listening experience. The Scans go I bit lower, but the SEAS is more alert and fast sounding (have no better explanation, sorry).

On the other hand the SEAS don’t have chance against the ScanSpeak 15W series in the midrange reproduction. The SEAS sound more recessed and muffled compared to the Scans.

However as a woofer in small 3-way e.g. TMWW paired with perhaps the ScanSpeak 10F as midrange, would be a killer.

Each H1520 requires a 14litre box and can play down to the low 30:ies (in room response).
