At the moment, I’m sorting out my home audio set up. I was inspired by PWK’s Dipoles where Pete uses a pair of Dayton Audio speakers ( www.youtube.com/watch?v=qCDR_PKk8FY ) and this design (images & link to the project below) where an Alpine SWS-1023D 10″ subwoofer has been used to help the low frequencies along.

This is where the Alpine speakers come in.
If my understanding on IB speaker and subwoofer designs is correct, one of the most common features sought for in a project like this, is for either the speaker of subwoofer to have a high QTS of around 0,5 or more. My disastrous project with the Alpine SPR-69 6×9 speakers taught me one thing, focus on the project first and foremost, be true to the aims of your project (and realistic) and then find the components best suited to the project.
Of course I simple did this in reverse and did what 95% of people do. Find or buy components first, then try to get them to do what you want. It can work … sometimes, but the Alpines have such high Q’s, and my desired outcomes was near impossible.
I am being hard on myself. It was only until after I bought the SPR-69’s that I found out what the T/S parameters were (after contacting Alpine). As a consequence, I was also told that the SPG and/or SPS speakers also had very high Q’s. Its not a disaster and I wouldn’t anyone off buying Alpine speakers, far from it. They are superb speakers which I wish more people would choose over the many poor but expensive speakers. Yes Vibe springs to mind!

I’ve played around with a pair of Alpine SXE 1025s 4″ speakers, then moved up to a pair of Alpine SXE 1325s 5.25″ speakers. Now I’m onto a pair of Alpine Alpine SPS-517 5×7 speakers, and they really, really kick. I’ve got my Muse MU-15 MKII (15 watts @ 4 ohm) amp at about 12:30 on the volume dial, and that’s plenty enough!
Am I going to keep it pure Alpine.
I was looking at buying either a pair of Peerless SLS 6.5″ woofers (subwoofer) or go mad and buy a pair of Peerless XLS10 (P830452) subwoofers, and bi-amp the system. I have a Class D amp on the way. for reasons of size, I don’t really want to go bigger than 10″ subs.
And then for a dedicated subwoofer, I’m going to use my Sundown Audio SA-12.
