Peerless 830869 8" Nomex Cone HDS Woofer
Do you think this would be OK to crossover @ 2500hz? This would be for a 2 way design with 1" tweeter.
Yes this will work with a crossover of 2,500 Hz.

Could these be used in a well dampened and fairly sealed car door ?
This will work well in a car door but I would not expect much below about 50 Hz from them.

are the parameters above your own measurements?
just checking as there seem to be many variations for this driver!Many thanks
The parameters we have listed are derived from the Peerless spec sheet that is available on this product page to the right of the Product Details. There is only one variation in power handling although I will have this updated to reflect what is on the spec sheet.

B&W DM 110
Hello, I was wondering if anyone would know if this speaker would be a direct replacement for the 8" in the B&W DM 110, looks like it would but i don't have any dimentions. Thanks in advance
You would also need to confirm that both speakers have the same impedance, and look at the SPEAKER BUILDING tab, then WOOFER SELECTION GUIDE to see if the cabinet size matches... Then, hopefully, both woofers have the same sensitivity ie 89db 1W/1M. Now this woofer will sound different than the B&W - so if you are changing one, you should change both speakers so that they match sonically.

MTG90: What software was used to calculate 1.0 cu ft at 35hz, and...
Thanks for your review. In your recommendation did you take into consideration the volume consumed by the port itself? or the volume consumed by the woofer itself?, or the volume consumed by at least a typical 3/4" thick brace down the middle of the cabinet? I ask because it seems some online software does consider this, while others does not. Tymphany recommends 1.1 cu ft for this woofer but provides no data on port or other factors taking away from volume as I just mentioned. I would prefer to do 1.1 cu ft at 35hz for this woofer IF it can be achieved - including what the woofer, brace, .75" wood take away from the volume specifications. Your final thoughts?
mtg90 provides exceptional specs for this driver. In his cabinet volume quotes - they do not account for the volume displaced by the driver in the cabinet, or bracing etc. Internal volume is accurate - how you build it is up to you. In general a larger cabinet will provide better bass quality and you then have the ability to tweak your design by modifying the port. 1.1 cu ft leaves you little option after a build out. Have fun with your project!

Can someone at PE Tech accurately reconfirm what the "vented box size" and "port size" would be for this Peerless 830869 woofer tuned to 43hz?
I've tried several calculators and found references from different sources all giving somewhere between 1.1 to 1.28 cu ft for volume and the port sizes vary greatly. Looking for someone who has access to a much more sophisticated software package to help get the volume and tuned port sizes correct, please. Thanks in advance.
Both enclosure volume and port diameter will change the port length for a given tuning frequency. That said 43 hz is too high a frequency to be tuning this driver in any size enclosure unless you want a big bump in your frequency response.Something like 35hz is much better. You would want at least a 3" diameter port with this driver in order to keep port air velocity down to acceptable levels. This driver works well in a 1 to 2 cu ft enclosure tuned to ~35 hz.Size, Tuning: Port diameter, Port Length1 cu ft, 35hz: 3"D, 13"L --or-- 4"D, 25"L1.5cu ft, 35hz: 3"D, 8"L --or-- 4"D, 15.6"L2 cu ft, 35hz: 3"D, 5.5"L --or-- 4"D, 11"LAnd just to throw it in 43hz tuning:1 cu ft, 43hz: 3"D, 8"L --or-- 4"D, 15.4"L1.5 cu ft, 43hz: 3"D, 4.6"L --or-- 4"D, 9.3"L2 cu ft, 43hz: 3"D, 3"L --or-- 4"D, 6.25"L
