Would it be possible to add in a mid woofer like a CSS SDX7 or a EL166 to a Pensil enclosure?
I've been experimenting with an ESP Linkwitz Riley active crossover at 300Hz with my Pensil 10.2 handling the higher frequencies with my KT88 SET and a TA2020 digital amp for the bottom frequencies thro an old KEF Cresta 2 bookshelves. I quite like what I hear with the bass reinforcement but will shift the XO frequencies to around 150-200Hz to make use of the Alpair 10.2's excellent mids.
Now what is bothering me is the extra 2 sets of speakers that does not integrate well into the living room and the domestic controller.

no chance at all to mod the pensils? 😕 i was hoping if it would be an easy add on as space is limited around here.
Trying to reuse the Pensil box would be non-optimal, but could be done if you have a removable back (and left out the holey brace).
You would need to partition of a smallish enclosure for the A10.2 -- i'd suggust about 10 litres. Then modify what is left to accomodate the woofer. SDX7 works nicely in 14-17 litres sealed.
Where you can put a partition is limited to just under the A10, leaving about 20 litres for the A10 and 46 litre for the bass driver.

Thanks Dave! I've built the pensil with a removable back and without the holey brace. 😀
Should I put the SDX7 front firing or side firing like the Tysens? I guess I'll have to cover the Pensil port from the inside.
Can't wait to place an order for the SDX7😀

You will need to decrease the volume of at least the woofer chamber, even if you get 2 per side.
I'd side mount them.

Yah will need to half the volume for around 17L
How about the EL166 compared to the SDX7. Cost a third of the SDX7. Both are different in construction though.

EL166 is a good woofer, especially of price is taken into consideration. I think the SDX7 is better.
