Homebrew sub with RF-7 woofers

[DougSchaefer]

Perhaps I am doing this in the backwards order, but -

I bought 2 RF-7 woofers (K-1089-AV) 10 inches with the intention of parting out a JBL PSW-110 subwoofer for its amp and crossovers. Plan to build one bass reflex box for those two Klipsch speakers. Internal volume of 6200 cubic inches (or about 100 liters) fits in the physical space available.

Why bother? It's just that the Heresies arrive Wednesday (smiling) and maybe the JBL sub will start sounding a little tubby. Besides my saw works fine. Or maybe I fell for the price on the Klipsch woofers on eBay ($112.50)

Emailed Klipsch for the Thiele Small parameters on the K-1089-AV and have not received yet. If anybody here knows them I could try to plan enclosure volume and port configurations.

I also welcome other suggestions for enclosure design. Planning both speakers (in phase) to the front and port(s) to the rear. Double thickness 3/4 in. MDF throughout. Don't like box resonance; lots of screws & glue.

Thanks for any ideas.

The only RF-7 woofers available from any source other than Klipsch are defective/stolen units destined for the crusher and diverted.

Do not invest in these parts which did not pass QC and do not buy any if you see them available. Your work to build a project including these defective parts will be wasted. It's unfortunate that someone would foist these items on an unsuspecting public.

Hmmm... That is not what I wanted to hear. Neither is it what I heard from the seller.

Certainly explains why Cust. Svc. was not inclined to tell me the T-S
