SEAS 10" woofers H1305 (CA26RFX) or H1209 (L26RFX/P) OR ....?

Francec · 7th December 2009, 01:36 AM

Has anyone used either of these woofers in DIY?
There quite a few posts about smaller SEAS drivers that,generally, speak highly of them but virtually nothing about the larger drivers.
I have 8" Peerless 830868 as woofers in 3 way actives and am hankering for a 10" woofer in their place. They are crossed at 300Hz with LR 24dB.
I was looking at the 10" SB Acoustics but, while they are listed as having 88dB at 2.83 V 1m sensitivity, the response graph shows 10dB less sensivity. I am a bit wary now.
If not the SEAS, does have anyone have any suggestions, either for sealed or vented but with an upper box size of 60-70 litres? (Would love ScanSpeaks but close to $AU500 is a bit too much.)

The choice is large
Peerless 830668 ? 42L closed box the 12" 830669 70L closed box.
Otherwise Seas the L26RFX 50L closed box or 70L@24Hz
CA26RFX 74L@34Hz
CA26RE4X 60L@34Hz
Or the D1001-04 L26ROY 45L@27Hz.

it depends on your budget and your taste.

Thanks Jerome,
Around $200 Oz, maybe higher if I can keep it quiet from you know who (

), so the SEAS seems a good fit. Where did you get those numbers, btw?
Have you used any of the SEAS 10" drivers, at all?

I used winisd for the volume calculations and I only have used the 10" and 12" Peerless.

Hi Francec, The only 10" drivers I have any experience with are no longer available. I've looked at a lot recently due to the three way reference thread, and the CA26RFX seems to have some consensus as being the driver that will be chosen there. The Seas you mentioned models well in a vented enclosure between 66 and 72L. You might want to have a read through the three way reference thread as quite a few drivers were discussed there.

Tony.

Hello. I use the Seas L26RFX/P in 50 L closed box. Really like how they sound. I'm running them up to 120Hz/LR24 with active xo. Deep, tight and precise bass. I guess the big issue is if they'll have enough Xmax for your needs. I use two of them pr. side and that's enough for my needs.

Hi Johan,
Two per side? So you have two 50 litre compartments in one speaker?
What are you using after 120Hz?
